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>

      </dependency>
  </dependencies>

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:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.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>

<!--    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-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>
<!--    配置Mapper扫描器-->

        <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">

                           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!--    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"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         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>
  </listener>

<!--  编码过滤器-->

  </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
