IDEA搭建SSMM框架（详细过程）

IDEA搭建SSMM框架（详细过程）

相关环境

• Intellij IDEA Ultimate
• Tomcat
• JDK
• MySql 5.6（win32/win64）
• Maven （可使用Intellij IDEA自带的）

搭建步骤

创建项目工程

1、创建工程，选择Maven

2、填写项目信息

初始化配置

1、Maven配置

先说Maven的项目依赖配置文件pom.xml，我们进入mvn repository 查找需要搜索的包结果如图：

点击进入第一个搜索结果，然后各种版本

点击所需版本。如图：



里面的dependency即为所需标签。

工程整体结构

总体工程结构：

包括：Maven包依赖配置文件pom.xml、springMVC配置文件spring-mvc.xml、mybatis数据看配置文件spring-mybatis.xml jdbc.properties以及mybatis自动构建数据库工具配置文件generatorConfig.xml generator.properties、log日志配置文件log4j.properites、web配置文件web.xml、java类相关等。

IDEA默认快捷键选中+F4唤出工程设置，可以配置相关的Sources、Tests、Resources等文件夹类型。

Maven配置文件

pom.xml添加依赖包信息如下：

点击构建插件

输入命令：mybatis-generator:generate -e

选中generator插件，点击运行即可，在generatorConfig.xml配置的相关文件将会自动生成。其中数据库驱动包需要指定路径。构建的内容如下所示。

注意：

在IDEA中，生成在mapping中的xml会报找不到的错误，这将mapping中的内容拷贝到resources/mapper中，并指定mapper为resources类型文件夹。



对应spring—mybatis.xml中的如下内容：

<!-- 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 -->

Java类

在main文件夹下创建文件夹java，点击右键将java作为source文件夹，并生成相应包结构：

service

接口

// UserService.java
package com.ssm.service;

import com.ssm.model.User;

public interface UserService {
    public User findUserById(int id);
    public void addUser(User user);
}

实现类

// UserServiceImpl.java
package com.ssm.service;

import com.ssm.dao.UserMapper;
import com.ssm.model.User;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import javax.annotation.Resource;

@Transactional
@Service
public class UserServiceImpl implements UserService {

    @Resource
    private UserMapper userMapper;

    public User findUserById(int id) {
        return userMapper.selectByPrimaryKey(id);
    }

    public void addUser(User user) {
        userMapper.insert(user);
    }
}

测试类

将java文件夹设置为Tests类型,并添加测试类

// TestMybatis.java
package com.ssm.test;

import com.alibaba.fastjson.JSON;
import com.ssm.model.User;
import com.ssm.service.UserService;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import javax.annotation.Resource;

@RunWith(SpringJUnit4ClassRunner.class)     //表示继承了SpringJUnit4ClassRunner类
@ContextConfiguration(locations = {"classpath:spring-mybatis.xml"})
public class TestMybatis {
    private Logger logger = Logger.getLogger(TestMybatis.class);

    @Resource
    private UserService userService;

    @Test
    public void findUserByIdTest() {
        User user = userService.findUserById(1);
        System.out.println(user.getUsername());
        logger.info("值："+user.getUsername());
        logger.info(JSON.toJSONString(user));
    }

}

Controller

 // UserController.java
package com.ssm.controller;

import com.ssm.model.User;
import com.ssm.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;

@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/QueryUser.action")
    public String toIndex(HttpServletRequest request, Model model){
        int userId = Integer.parseInt(request.getParameter("id"));
        User user = this.userService.findUserById(userId);
        model.addAttribute("user", user);
        return "User";
    }
}
