本文主要是介绍SSM框架整合，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
SSM项目整合
由于SpringMVC是Spring框架中的一个模块，所以SSM框架整合只需要进行Spring与Mybatis和SpringMVC和Mybatis之间的整合
1、导入依赖
<dependencies>
<!-- 单元测试整合-->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.13.2</version>

<artifactId>spring-test</artifactId>
<version>5.3.20</version>
</dependency>
<!-- SpringContext-->

2、编写配置文件
jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/ssm jdbc.username=root jdbc.password=root jdbc.maxTotal=30 jdbc.maxIdle=10 jdbc.initialSize=5
applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
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">
<!-- 读取数据库配置信息-->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 配置数据源-->
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource">

</bean>
<!-- 事务管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 注册事务管理器驱动，开启事务注解-->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!-- 配置MyBatis工厂-->

<property name="configLocation" value="classpath:mybatis-config.xml"/>
</bean>
<!-- 配置Mapper扫描器-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="cn.pickle.dao"/>
</bean>
<!-- 扫描Service-->
<context:component-scan base-package="cn.pickle.service"/>
</beans>
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>
<!-- 配置别名-->
<typeAliases>

</configuration>
springmvc-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- 扫描前端控制器的包-->
<context:component-scan base-package="cn.pickle.controller"/>
<!-- 配置注解驱动-->
<mvc:annotation-driven/>
<!-- 定义视图解析器-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
<!--配置加载Spring文件加载的监听器-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

<!-- 编码过滤器-->

</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置SpringMVC前端控制器-->

</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
3、编写Po
package cn.pickle.po;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
/**
* @author Pickle
* @version V1.0
* @date 2022/7/15 20:32
*/
@Data
@NoArgsConstructor
@AllArgsConstructor
public class User {
private Integer id;
private String username;
}
4、编写Dao
package cn.pickle.dao;
import cn.pickle.po.User;
import org.apache.ibatis.annotations.Select;
/**
* @author Pickle
* @version V1.0
* @date 2022/7/15 20:38
*/
public interface UserDao {
/**
* 根据Id查询User
* @param id
* @return
*/
@Select("select * from t_user where id= #{id}")
public User findUserById(Integer id);
}
5、编写Service
package cn.pickle.service.Impl;
import cn.pickle.dao.UserDao;
import cn.pickle.po.User;
import cn.pickle.service.UserService;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import javax.annotation.Resource;
/**
* @author Pickle
* @version V1.0
* @date 2022/7/15 20:41
*/
@Service
@Transactional
public class UserServiceImpl implements UserService {
@Resource(name = "userDao")
private UserDao userDao;
@Override
public User findUserById(Integer id) {
return userDao.findUserById(id);
}
}
6、编写Controller
package cn.pickle.controller;
import cn.pickle.po.User;
import cn.pickle.service.UserService;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.annotation.Resource;
/**
* @author Pickle
* @version V1.0
* @date 2022/7/15 20:49
*/
@Controller
public class UserController {
@Resource(name = "userServiceImpl")
private UserService userService;
@RequestMapping(value = "/findUserById")
public String findUserById(Integer id, Model model){
final User user = userService.findUserById(id);
model.addAttribute("user",user);
return "user";
}
}
7、编写jsp
