使用idea搭建SSM项目

 

本篇文章主要内容是介绍如何使用IDEA创建spring + SpringMVC + MyBatis的一个web项目，下面会给出项目搭建的详细步骤以及相关的配置文件。

一、创建一个项目工程

1.1 在File下拉->New -> project

1.2选择maven工程，勾选create from archetype，选择maven-archetype-webapp。next

1.3 填写groupid和artifactid。next

1.4设置maven home 。next

 

1.5 打开pom.xml加入坏境所需的依赖pox.xml

1.6 设置工程的jdk等

1.7 添加工程目录并设置工程目录属性，java目录为sources，resources的目录属性为resources

1.8 目录结构如下所示。

 

二、代码部分

bean:

package ssm.bean;

/**
 * @author chenjw
 * @version v1.0.0
 * @description
 * @date Created in 2018/8/3 10:07
 */

public class User {
    private String id;
    private String name;
    private String age;
set,get略
}

dao：

package ssm.dao;

import org.springframework.stereotype.Repository;
import ssm.bean.User;

/**
 * @author chenjw
 * @version v1.0.0
 * @description
 * @date Created in 2018/8/3 10:11
 */
@Repository
public interface UserDao {
    User showUser(String id);
}

service:

package ssm.service;

import ssm.bean.User;

/**
 * @author chenjw
 * @version v1.0.0
 * @description
 * @date Created in 2018/8/3 10:14
 */

public interface UserService {
    User showUser(String id);
}

serviceImpl

package ssm.service;

import ssm.bean.User;
import ssm.dao.UserDao;

import javax.annotation.Resource;

/**
 * @author chenjw
 * @version v1.0.0
 * @description
 * @date Created in 2018/8/3 10:15
 */

public class UserServiceImpl implements UserService{
    @Resource
    private UserDao uDao;

    public User showUser(String id) {
        return uDao.showUser(id);
    }
}

package ssm.controller;

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import ssm.bean.User;
import ssm.service.UserService;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * @author chenjw
 * @version v1.0.0
 * @description
 * @date Created in 2018/8/3 10:17
 */
@Controller
@RequestMapping("/uus")
public class UserController {
    @Autowired
    private UserService uService;

    private  static final Logger LOG = Logger.getLogger(UserController.class);
    @RequestMapping("/get.do")
    public User showUser(HttpServletRequest req, HttpServletResponse resp){
      User u = uService.showUser("1");
        LOG.info("....==>"+u.getName());
        return u;
    }
}

spring-mvc.xml

    
    

    
    
        
            
                text/html;charset=UTF-8
            
        
    
    
    
        
            
                 
            
        
    


    
    
        
        
    

    
    
        
        
        
        
        
        
    

spring-mybatis.xml

 

 

sql语句

DROP TABLE IF EXISTS `t_user`;
CREATE TABLE `t_user` (
  `id` varchar(255) NOT NULL,
  `name` varchar(255) DEFAULT NULL,
  `age` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of t_user
-- ----------------------------
INSERT INTO `t_user` VALUES ('1', 'xiaoming', '11');

  Archetype Created Web Application

  
    contextConfigLocation
    classpath:spring-mybatis.xml
  

  
    log4jConfigLocation
