Eclipse中使用Maven搭建SSM框架
Eclipse中不使用Maven搭建SSM框架：https://www.cnblogs.com/xuyiqing/p/9569459.html
IDEA中使用Maven搭建SSM框架：https://www.cnblogs.com/xuyiqing/p/10522339.html
Eclipse新建Maven Project->archetype选择webapp
Window-Preferences->搜索JRES配置本地JDK（推荐1.8，过高或过低可能出现未知问题）
Window-Preferences->搜索Maven配置本地Maven和settings.xml
Window-Preferences->搜索Server配置本都Tomcat
然而新建好的Maven Project是报错的
解决：选中项目右键Properties->Java Build Path->Libraries->Add Library，添加Server Runtime，应用后就不会报错了
pom.xml加入Maven编译插件，并配置JDK和编码：
<build> <finalName>xxx</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.6.1</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF8</encoding> </configuration> </plugin> </plugins> </build>
保存后，项目右键Maven->Update ...
由于自动构建的项目缺少src/test/resources目录，可以选择性地自行创建
Java Resource目录右键new source folder：
Project Name和项目名一致
Folder Name：src/test/resources
完成后
项目右键Properties->Java Build Path->Source
如果是最新版Eclipse，在src/test/java中选中Contains Test Source->Toggle
src/test/resources设置Output和src/test/java地Output路径一致
应用
设置Project Facets：可以省略，我设置只是为了提高效率
项目右键设置properties->搜索facets，设置Dynamic Web Module为3.1
发现设置失败，这是Eclipse的BUG，无论新旧版本
解决办法：进入项目路径.settins目录，打开目录中的XML文件：修改为下图所示
<?xml version="1.0" encoding="UTF-8"?> <faceted-project> <fixed facet="wst.jsdt.web"/> <installed facet="jst.web" version="3.1"/> <installed facet="wst.jsdt.web" version="1.0"/> <installed facet="java" version="1.8"/> </faceted-project>
web.xml也要修改为3.1版本：
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1" metadata-complete="true"> <display-name>Archetype Created Web Application</display-name> </web-app>
测试：启动项目，如果正常跳到index.jsp说明准备工作顺利完成
接下来开始正式搭建SSM框架：
pom.xml：我选取了SSM框架和一些常用的包作为依赖
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.dreamtech</groupId> <artifactId>xiuxian</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>xiuxian Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <spring.version>4.3.7.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- 日志 --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.2.1</version> </dependency> <!-- 数据库 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.37</version> </dependency> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>0.9.1.2</version> </dependency> <!-- MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.2</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.1</version> </dependency> <!-- 其他包 --> <dependency> <groupId>taglibs</groupId> <artifactId>standard</artifactId> <version>1.1.2</version> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.8.7</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>commons-collections</groupId> <artifactId>commons-collections</artifactId> <version>3.2</version> </dependency> <!-- 验证码 --> <dependency> <groupId>com.github.penggle</groupId> <artifactId>kaptcha</artifactId> <version>2.3.2</version> </dependency> </dependencies> <build> <finalName>xiuxian</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.6.1</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF8</encoding> </configuration> </plugin> </plugins> </build> </project>
新建两个source folder:
src/main/resources/spring：用于放Spring配置文件
src/main/resources/mapper：用于放MyBatis的映射文件
在src/main/resources下创建数据库连接配置文件：jdbc.properties：
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/xxx?useUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=xxx
在src/main/resources下创建MyBatis配置文件：mybatis-config.xml：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!-- 配置全局属性 --> <settings> <!-- 使用JDBC的getGeneratedKeys获取数据库自增主键值 --> <setting name="useGeneratedKeys" value="true" /> <!-- 使用列标签替换列别名 --> <setting name="useColumnLabel" value="true" /> <!-- 开启驼峰命名转换 --> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings> </configuration>
配置Spring：
在src/main/resources/spring下创建spring-dao.xml：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:property-placeholder location="classpath:jdbc.properties" /> <!-- 数据库连接池 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <!-- 读取 --> <property name="driverClass" value="${jdbc.driver}" /> <property name="jdbcUrl" value="${jdbc.url}" /> <property name="user" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <property name="maxPoolSize" value="30" /> <property name="minPoolSize" value="10" /> <property name="autoCommitOnClose" value="false" /> <property name="checkoutTimeout" value="10000" /> <property name="acquireRetryAttempts" value="2" /> </bean> <!-- 配置SqlSessionFactory对象 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 注入数据库连接池 --> <property name="dataSource" ref="dataSource" /> <!-- 配置MyBaties全局配置文件：mybatis-config.xml --> <property name="configLocation" value="classpath:mybatis-config.xml" /> <!-- 使用别名 --> <property name="typeAliasesPackage" value="org.dreamtech.xxx.entity" /> <!-- 扫描mapper文件 --> <property name="mapperLocations" value="classpath:mapper/*.xml" /> </bean> <!-- 配置扫描dao接口包 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 注入sqlSessionFactory --> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> <!-- 扫描 --> <property name="basePackage" value="org.dreamtech.xxx.dao" /> </bean> </beans>
在src/main/resources/spring下创建spring-service.xml：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 扫描 --> <context:component-scan base-package="org.dreamtech.xxx.service" /> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 注入数据库连接池 --> <property name="dataSource" ref="dataSource" /> </bean> <!-- 配置基于注解的声明式事务 --> <tx:annotation-driven transaction-manager="transactionManager" /> </beans>
在src/main/resources/spring下创建spring-web.xml：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <!-- 开启SpringMVC注解模式 --> <mvc:annotation-driven /> <!-- 放行静态资源 --> <mvc:resources mapping="/resources/**" location="/resources/" /> <mvc:default-servlet-handler /> <!-- 定义视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/html/" /> <property name="suffix" value=".html" /> </bean> <!-- 扫描 --> <context:component-scan base-package="org.dreamtech.xxx.web" /> </beans>
web.xml中对Spring进行配置：顺便我也配置了验证码插件Kaptcha
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1" metadata-complete="true"> <display-name>xxx</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 验证码 --> <servlet> <servlet-name>Kaptcha</servlet-name> <servlet-class>com.google.code.kaptcha.servlet.KaptchaServlet</servlet-class> <init-param> <param-name>kaptcha.border</param-name> <param-value>no</param-value> </init-param> <init-param> <param-name>kaptcha.textproducer.font.color</param-name> <param-value>red</param-value> </init-param> <init-param> <param-name>kaptcha.textproducer.char.string</param-name> <param-value>ACDEFGHJKMNPRSTUVWX23456789</param-value> </init-param> <init-param> <param-name>kaptcha.textproducer.char.length</param-name> <param-value>4</param-value> </init-param> <init-param> <param-name>kaptcha.textproducer.font.names</param-name> <param-value>Arial</param-value> </init-param> <init-param> <param-name>kaptcha.image.width</param-name> <param-value>135</param-value> </init-param> <init-param> <param-name>kaptcha.image.height</param-name> <param-value>50</param-value> </init-param> <init-param> <param-name>kaptcha.textproducer.font.color</param-name> <param-value>red</param-value> </init-param> <init-param> <param-name>kaptcha.textproducer.font.size</param-name> <param-value>43</param-value> </init-param> <init-param> <param-name>kaptcha.noise.color</param-name> <param-value>black</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>Kaptcha</servlet-name> <url-pattern>/Kaptcha</url-pattern> </servlet-mapping> <!-- 配置Spring --> <servlet> <servlet-name>DispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-*.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>DispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
到这里就配置完成了！
下面进行测试：
我写一个简单的实体类，并在数据库加入一条信息
package org.dreamtech.xiuxian.entity; public class Person { private String userId; private Integer exp; private String stateId; private String username; private String password; public String getUserId() { return userId; } public void setUserId(String userId) { this.userId = userId; } public Integer getExp() { return exp; } public void setExp(Integer exp) { this.exp = exp; } public String getStateId() { return stateId; } public void setStateId(String stateId) { this.stateId = stateId; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } @Override public String toString() { return "Person [userId=" + userId + ", exp=" + exp + ", stateId=" + stateId + ", username=" + username + ", password=" + password + "]"; } }
Dao层测试：
package org.dreamtech.xiuxian.dao; import org.apache.ibatis.annotations.Param; import org.dreamtech.xiuxian.entity.Person; public interface PersonDao { /** * 根据用户名和密码得到用户信息 * * @return 用户 */ Person getPersonByUsernameAndPassword(@Param("username") String username, @Param("password") String password); }
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="org.dreamtech.xiuxian.dao.PersonDao"> <select id="getPersonByUsernameAndPassword" resultType="Person"> SELECT user_id,exp,state_id,username,password FROM tb_person WHERE username=#{username} AND password=#{password} </select> </mapper>
package org.dreamtech.xiuxian.dao; import org.dreamtech.xiuxian.entity.Person; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration({ "classpath:spring/spring-dao.xml" }) public class DaoTest { @Autowired private PersonDao personDao; @Test public void testPersonDao() { Person person = personDao.getPersonByUsernameAndPassword("test", "test"); System.out.println(person.getUserId()); } }
Dao层测试成功！
Service层测试：
package org.dreamtech.xiuxian.service; import org.dreamtech.xiuxian.entity.Person; public interface PersonService { /** * 根据用户名和密码得到用户信息 * * @return 用户 */ Person getPersonByUsernameAndPassword(String username, String password); }
package org.dreamtech.xiuxian.service.impl; import org.dreamtech.xiuxian.dao.PersonDao; import org.dreamtech.xiuxian.entity.Person; import org.dreamtech.xiuxian.service.PersonService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; @Service public class PersonServiceImpl implements PersonService { @Autowired private PersonDao personDao; @Override public Person getPersonByUsernameAndPassword(String username, String password) { if (username != null && !username.equals("")) { username = username.replace(" ", ""); } else { throw new RuntimeException("username is null"); } if (password != null && !password.equals("")) { password = password.replace(" ", ""); } else { throw new RuntimeException("password is null"); } Person person = null; try { person = personDao.getPersonByUsernameAndPassword(username, password); } catch (Exception e) { e.printStackTrace(); throw new RuntimeException("error:PersonDao.getPersonByUsernameAndPassword"); } return person; } }
package org.dreamtech.xiuxian.service; import org.dreamtech.xiuxian.entity.Person; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration({ "classpath:spring/spring-dao.xml", "classpath:spring/spring-service.xml" }) public class ServiceTest { @Autowired private PersonService personService; @Test public void testPersonDao() { Person person = personService.getPersonByUsernameAndPassword("test", "test"); System.out.println(person.getUserId()); } }
Service层测试成功！
Controller层测试：
package org.dreamtech.xiuxian.web; import java.util.HashMap; import java.util.Map; import javax.servlet.http.HttpServletRequest; import org.dreamtech.xiuxian.entity.Person; import org.dreamtech.xiuxian.service.PersonService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping("/person") public class PersonController { @Autowired private PersonService personService; @RequestMapping("login") private Map<String, Object> login(HttpServletRequest request) { String username = request.getParameter("username"); String password = request.getParameter("password"); Map<String, Object> modelMap = new HashMap<String, Object>(); try { Person person = personService.getPersonByUsernameAndPassword(username, password); modelMap.put("person", person); modelMap.put("success", true); } catch (Exception e) { modelMap.put("success", false); } return modelMap; } }
Controller层就不需要写测试类了，直接访问：
http://localhost:8080/xiuxian/person/login?username=test&password=test
所有测试完成！
