注：不求步道于众人，抵消遗忘留足痕
1.新建Maven工程设置字符编码为utf-8，初始化项目结构(service,controller,mapper,utils....)
2.编写pom.xml文件
<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>com.cbooy</groupId> <artifactId>xxx</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>xxx</name> <url>http://maven.apache.org</url> <properties> <!-- spring版本号 --> <spring.version>3.2.4.RELEASE</spring.version> <!-- mybatis版本号 --> <mybatis.version>3.2.4</mybatis.version> <!-- log4j日志文件管理包版本 --> <slf4j.version>1.6.6</slf4j.version> <log4j.version>1.2.9</log4j.version> </properties> <dependencies> <!-- servlet start --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <scope>provided</scope> <version>2.2</version> </dependency> <!-- servlet end --> <!-- junit start --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!-- junit end --> <!-- spring start --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</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-oxm</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-jdbc</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-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- spring end --> <!-- spring mybatis start --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- spring mybatis end --> <!-- mybatis start --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis end --> <!-- mysql driver start --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> <!-- mysql driver end --> <!-- ali druid from wenshao start --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.2</version> </dependency> <!-- ali druid from wenshao end --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> <!-- cglib start --> <dependency> <groupId>cglib</groupId> <artifactId>cglib</artifactId> <version>2.2.2</version> </dependency> <!-- cglib end --> <!-- fast json start --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.5.4</version> </dependency> <!-- fast json end --> <!-- guava start --> <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>18.0</version> </dependency> <!-- guava end --> </dependencies> <build> <finalName>xxxx</finalName> </build> </project>
3.配置MyBatis
1). 在src/main/resources目录下新建目录mybatis，并新建configuration.xml文件
<?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> <settings> <setting name="lazyLoadingEnabled" value="true" /> <setting name="multipleResultSetsEnabled" value="true" /> <setting name="useColumnLabel" value="true" /> <setting name="useGeneratedKeys" value="false" /> <setting name="defaultExecutorType" value="SIMPLE" /> <setting name="defaultStatementTimeout" value="25000" /> </settings> <mappers> <mapper resource="mybatis/mappers/UserMapper.xml" /> </mappers> </configuration>
2). 在mybatis目录下新建目录mappers目录，并新建用于测试的mapper文件，UserMapper.xml
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.cbooy.ms.mapper.UserMapper"> <resultMap type="User" id="UserMap"> <result column="id" property="id" /> <result column="name" property="name" /> </resultMap> <insert id="insertUser" parameterType="User"> insert into t_user(id,name) values(#{id},#{name}) </insert> </mapper>
3).新建接口UserMapper
public interface UserMapper { void insertUser(User user); }
4). 新建spring配置文件dao层的配置
<?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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <!-- <context:property-placeholder location="classpath:jdbc.properties"/> --> <bean id="druidDataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close"> <property name="url" value="jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf-8" /> <property name="username" value="root" /> <property name="password" value="hao123" /> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="filters" value="stat" /> <property name="maxActive" value="100" /> <property name="initialSize" value="30" /> <property name="maxWait" value="60000" /> <property name="minIdle" value="10" /> <property name="timeBetweenEvictionRunsMillis" value="60000" /> <property name="minEvictableIdleTimeMillis" value="300000" /> <property name="validationQuery" value="SELECT 'x'" /> <property name="testWhileIdle" value="true" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <property name="maxOpenPreparedStatements" value="20" /> <property name="removeAbandoned" value="true" /> <!-- 打开removeAbandoned功能 --> <property name="removeAbandonedTimeout" value="1800" /> <!-- 1800秒，也就是30分钟 --> <property name="logAbandoned" value="true" /> <!-- 关闭abanded连接时输出错误日志 --> </bean> <!-- 配置 SqlSessionFactoryBean 并配置 typeAliasesPackage 指定扫描的实体类的包，自动别名 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- <property name="dataSource" ref="dataSource" /> --> <property name="dataSource" ref="druidDataSource" /> <property name="configLocation" value="classpath:mybatis/configuration.xml" /> <property name="typeAliasesPackage" value="com.cbooy.ms.model" /> </bean> <!-- 扫描 mapper 文件 自动扫描 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.cbooy.ms.mapper" /> <property name="sqlSessionFactory" ref="sqlSessionFactory" /> </bean> <!-- 配置 事务管理器 --> <bean id="tx" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- <property name="dataSource" ref="dataSource" /> --> <property name="dataSource" ref="druidDataSource" /> </bean> <!-- 使用声明式事务 --> <tx:annotation-driven transaction-manager="tx" /> </beans>
4.配置Spring
1). 配置spring的bean文件
<?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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <context:component-scan base-package="com.cbooy.ms"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> <context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/> </context:component-scan> <import resource="classpath:springdao.xml" /> </beans>
2). 新建service层代码与dao层进行测试
public interface UserService { void addUser(User user); }
@Service public class UserServiceImpl implements UserService { @Autowired private UserMapper userDao; public void addUser(User user) { userDao.insertUser(user); } }
3). 测试在src/test目录下新建测试类 TestCases
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:springBeans.xml") public class TestService { @Autowired private UserService userService; @Test public void addTest(){ userService.addUser(new User(1,"hi")); } }
5.配置springmvc
1). 配置web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd "> <display-name>Monitor Sonar</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springBeans.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <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:springmvc.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> <servlet> <servlet-name>jsp</servlet-name> <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>jsp</servlet-name> <url-pattern>*.jsp</url-pattern> </servlet-mapping> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>false</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>/index.html</welcome-file> </welcome-file-list> </web-app>
2). 配置springmvc的相关配置文件
<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> <context:component-scan base-package="com.cbooy.ms" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /> <context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice" /> </context:component-scan> <!-- 配置视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"></property> <property name="suffix" value=".jsp"></property> </bean> <mvc:default-servlet-handler /> <mvc:annotation-driven></mvc:annotation-driven> </beans>
3).建立controller测试类UserController
@Controller @RequestMapping(value = "/ms/api", method = RequestMethod.GET) public class UserController { @Autowired private UserService userService; @RequestMapping("/addUser") @ResponseBody public User addUser(@RequestParam("user") String userNa){ System.out.println(userNa); User usr = new User(1,userNa); userService.addUser(usr); return usr; } }
至此配置部分完毕
可能存在的问题：
1.使用eclipse新建的maven项目中，在package explorer视图看不到src/main/java文件夹，新建时又提示文件夹已经存在等诸如此类的问题
解决：选中项目——>右键——>Build Path——>Configure Build Path——>Source,视图下一般src/main/java 处会报错，remove掉，在新建就可以了
