idea搭建ssm框架（超详细）
一。创建项目
先附上测试的数据库
DROP TABLE IF EXISTS `user`; CREATE TABLE `user` ( `id` int(5) NOT NULL AUTO_INCREMENT, `name` varchar(10) COLLATE utf8_bin DEFAULT NULL, `password` varchar(10) COLLATE utf8_bin DEFAULT NULL, `remark` varchar(50) COLLATE utf8_bin DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 COLLATE=utf8_bin; -- ---------------------------- -- Records of user -- ---------------------------- INSERT INTO `user` VALUES ('1', 'zhangsan', '123456', null); INSERT INTO `user` VALUES ('2', 'lisi', '123', null); INSERT INTO `user` VALUES ('3', 'wangan', '456', null); INSERT INTO `user` VALUES ('4', 'xinxi', '000', null);
1.new->project出现如下
点击next后出现如下填写GroupId和ArtifactId在点击next直至finish
2.构建目录结构
在main下新建java和resources目录如下并将java目录标记为Sources Root，resources标记为Resources Root
在java下新建如下包package
二。Spring MVC
1.首先引入Spring MVC依赖
<!-- Spring相关包 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</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-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>

<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>${spring.version}</version>
</dependency>
并添加<properties><spring.version>4.3.8.RELEASE</spring.version></properties>
2.在controller新建TestController类，在WEB-INF下新建static目录，还在WEB-INF下新建jsp目录并新建test.jsp页面
3.在web.xml添加dispatcherServlet
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>SSM2</display-name> <!-- 设计路径变量值 <context-param> <param-name>webAppRootKey</param-name> <param-value>springmvc.root</param-value> </context-param> --> <!-- Spring字符集过滤器 --> <filter> <filter-name>SpringEncodingFilter</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>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>SpringEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- springMVC核心配置 --> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!--spingMVC的配置路径 如果是classspath：资源是在resources下面--> <param-value>/WEB-INF/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 拦截设置 --> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
4.在WEB-INF下新建spring-mvc.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" 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-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <!-- 扫描controller（controller层注入） --> <context:component-scan base-package="com.exp.controller" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <mvc:annotation-driven /> <!-- 内容协商管理器 --> <!--1、首先检查路径扩展名（如my.pdf）；2、其次检查Parameter（如my?format=pdf）；3、检查Accept Header--> <bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"> <!-- 扩展名至mimeType的映射,即 /user.json => application/json --> <property name="favorPathExtension" value="true"/> <!-- 用于开启 /userinfo/123?format=json 的支持 --> <property name="favorParameter" value="true"/> <property name="parameterName" value="format"/> <!-- 是否忽略Accept Header --> <property name="ignoreAcceptHeader" value="false"/> <property name="mediaTypes"> <!--扩展名到MIME的映射；favorPathExtension, favorParameter是true时起作用 --> <value> json=application/json xml=application/xml html=text/html </value> </property> <!-- 默认的content type --> <property name="defaultContentType" value="text/html"/> </bean> <!-- 当在web.xml 中 DispatcherServlet使用 <url-pattern>/</url-pattern> 映射时，能映射静态资源 --> <mvc:default-servlet-handler /> <!-- 静态资源映射 --> <mvc:resources mapping="/static/**" location="/WEB-INF/static/"/> <!-- 对模型视图添加前后缀 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/> </beans>
5.部署
点击如下图
点击+号找到Local
接下来修改名字，选择Deployment点击+号，选择ssm2:war exploded,另外Application context填写的如果是ssm2，那么访问的时候就是localhost:8080/ssm2,部署结束。
6.启动测试
启动后默认访问的是index.jsp页面，可以访问http://localhost:8080/ssm2/test
如果页面乱码在头部加上<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
三。Spring与Mybatis
1.引入相关依赖
<!-- MyBatis相关包 -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.3.0</version>
</dependency>
<!-- MySQL相关包 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.26</version>
</dependency>
<!-- 数据库连接池 -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.0.20</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.alibaba/fastjson -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.31</version>
</dependency>
<!-- Spring集成MyBatis -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.2.3</version>
</dependency>
<!-- JSP标准标签库 -->

</dependency>
<!-- 日志相关包 -->
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.21</version>
</dependency>
2.生成实体与mybatis配置文件
在resources下新建generator目录并新建generatorConfig.xml文件
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <!--本地的数据库连接驱动地址--> <classPathEntry location="D:\OfficeWave\configdata\repository\mysql\mysql-connector-java\5.1.26\mysql-connector-java-5.1.26.jar"/> <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat"> <property name="beginningDelimiter" value="`"/> <property name="endingDelimiter" value="`"/> <property name="mergeable" value="false"></property> <!--数据库连接地址--> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/user" userId="root" password="root"> </jdbcConnection> <!--生成实体类（注意修改包路径）--> <javaModelGenerator targetPackage="com.exp.model" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator> <!--生成mapper.xml--> <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!--生成mapper.java（注意修改包路径）--> <javaClientGenerator type="XMLMAPPER" targetPackage="com.exp.mapper" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> <!--数据库中的表名称和对应的实体类名称--> </javaClientGenerator> <table tableName="user" domainObjectName="User"></table> </context> </generatorConfiguration>
在pom.xml中的<pluginManagement>标签下添加如下
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
<overwrite>true</overwrite>
<verbose>true</verbose>
</configuration>
</plugin>
</plugins>
双击运行即可
3.web.xml中引入spring相关配置
<!-- 读取spring配置文件 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
4.在resources下新建applicationContext.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:aop="http://www.springframework.org/schema/aop" 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/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd "> <!-- 1.配置jdbc文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations" value="classpath:jdbc.properties"/> </bean> <!-- 2.扫描的包路径，这里不扫描被@Controller注解的类 --><!--使用<context:component-scan/> 可以不在配置<context:annotation-config/> --> <context:component-scan base-package="com.exp"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <import resource="classpath:spring-mybatis.xml" /> </beans>
5.在resources下新建jdbc.properties文件和spring-mybatis.xml
jdbc.properties
jdbc_driverClassName =com.mysql.jdbc.Driver jdbc_url=jdbc:mysql://localhost:3306/user?useUnicode=true&characterEncoding=utf8 jdbc_username=root jdbc_password=root
spring-mybatis.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:aop="http://www.springframework.org/schema/aop" 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-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"> <!-- 3.配置数据源 ，使用的alibba的数据库--> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <!-- 基本属性 url、user、password --> <property name="driverClassName" value="${jdbc_driverClassName}"/> <property name="url" value="${jdbc_url}"/> <property name="username" value="${jdbc_username}"/> <property name="password" value="${jdbc_password}"/> <!-- 配置初始化大小、最小、最大 --> <property name="initialSize" value="10"/> <property name="minIdle" value="10"/> <property name="maxActive" value="50"/> <!-- 配置获取连接等待超时的时间 --> <property name="maxWait" value="60000"/> <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="60000" /> <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --> <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" /> <!-- 打开PSCache，并且指定每个连接上PSCache的大小 如果用Oracle，则把poolPreparedStatements配置为true，mysql可以配置为false。--> <property name="poolPreparedStatements" value="false" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="20" /> <!-- 配置监控统计拦截的filters --> <property name="filters" value="wall,stat" /> </bean> <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mapping.xml文件 --> <property name="mapperLocations" value="classpath:/mapper/*.xml"></property> </bean> <!-- DAO接口所在包名，Spring会自动查找其下的类 ,自动扫描了所有的XxxxMapper.xml对应的mapper接口文件,只要Mapper接口类和Mapper映射文件对应起来就可以了--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.exp.mapper" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!--======= 事务配置 End =================== --> <!-- 配置基于注解的声明式事务 --> <!-- enables scanning for @Transactional annotations --> <tx:annotation-driven transaction-manager="transactionManager" /> </beans>
6.编写代码
在service下新建接口UserService
package com.exp.service; import com.exp.model.User; import java.util.List; public interface UserService { List<User> selectAll(); }
在UserServiceImpl下新建类UserServiceImpl
package com.exp.service.impl;
import com.exp.mapper.UserMapper;
import com.exp.model.User;
import com.exp.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;
@Override
public List<User> selectAll() {
List<User> userList = userMapper.selectAll();
return userList;
}
}
类TestController
package com.exp.controller; import com.exp.model.User; import com.exp.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import java.util.List; @Controller @RequestMapping("/") public class TestController { @Autowired private UserService userService; @RequestMapping("/test") public String test(){ List<User> userList = userService.selectAll(); for (User user:userList){ System.out.println(user);
} return "test"; } }
7.测试
访问http://localhost:8080/ssm2/test
在server打印如下即搭建成功
