創建項目

file-new project

一路next.

目錄結構

手動創建缺少的文件夾

可以選中文件夾右鍵，將文件夾作爲資源根目錄（包）

修改pom.xml導入依賴

mybatis逆向工程創建mapper接口和xml文件

user表腳本

/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;

  `address` varchar(256) DEFAULT NULL COMMENT '地址',
  PRIMARY KEY (`id`)

在main/resources中創建generatorConfig.xml

</generatorConfiguration>

idea右側maven選項卡，選中mybatis-generator，綠色鍵運行

不報錯的話會生成這些文件

db.properties

在resources/config中創建db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/mybatis?characterEncoding=UTF-8
jdbc.username=root
jdbc.password=root

SqlMapConfig.xml

在resources/config/mybatis中創建SqlMapConfig.xml

基礎配置都整合在spring中，所以這裏只寫文件框架

<?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>
</configuration>

springmvc配置

在resource/config/spring中創建springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>

       <!--控制器映射器和控制器適配器-->

service接口與實現

UserService.java

package me.wangyq.ssm.service;

import me.wangyq.ssm.pojo.User;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

import java.util.List;

/**
 * Created by wangyq on 2016/5/28.
 */
public interface UserService {

    /**
     * 查找所有用戶
     * @return
     * @throws Exception
     */
    List<User> findUser() throws Exception;
}

UserServiceImpl.java

package me.wangyq.ssm.service;

import me.wangyq.ssm.mapper.UserMapper;
import me.wangyq.ssm.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import java.util.List;

/**

 */
@Service
public class UserServiceImpl implements UserService {
    @Autowired
    private UserMapper userMapper;

    public List<User> findUser() throws Exception {
        //null表示無條件查找
        List<User> users=userMapper.selectByExample(null);
        return users;
    }
}

控制器Controller

UserController.java

package me.wangyq.ssm.controller;

import me.wangyq.ssm.pojo.User;
import me.wangyq.ssm.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

import org.springframework.web.servlet.ModelAndView;

import java.util.List;

/**

@Controller
@RequestMapping("/user")
public class UserController {
    @Autowired
    private UserService userService;

    @RequestMapping("/findUser")
    public ModelAndView findUser() throws Exception{
        ModelAndView modelAndView=new ModelAndView();

        List<User> users=userService.findUser();
        modelAndView.addObject("users",users);
        modelAndView.setViewName("findUser");
        return modelAndView;
    }
}

tomcat配置運行

如果Settings中還未配置好tomcat，則選擇application server如圖添加本地tomcat

部署web application

file-project structure-artifacts

加號添加一個web application: exploded

發佈

run-edit configurations

配置完成，右上角綠色鍵運行

在數據庫表中添加一些數據，輸入URL地址，不出意外，可得到：

END.

手搭一次，寫一次，加深理解和印象。

spring中的註解千萬別寫漏了。

各配置文件的作用還有待記牢。
