idea搭建ssm框架

1、file-->new-->project-->maven....

2、建立后的目录：

3、pom.xml依赖建立：

6、db.properties(基于c3p0)

# mysql数据库

#最小连接数
c3p0.minPoolSize=10
#关闭连接后不自动commit
c3p0.autoCommitOnClose=false
#获取连接超时时间
c3p0.checkoutTimeout=10000
#当获取连接失败重试次数
c3p0.acquireRetryAttempts=2

import com.hdu.service.UserService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

@Service
public class UserServiceImpl implements UserService {
    @Resource
    private UserMapper userMapper;
    @Override
    public User findUserById(Integer id) {
        User user = userMapper.findUserById(id);
        return user;
    }
}

13、UserMapper接口

package com.hdu.dao;

import com.hdu.entity.User;

public interface UserMapper {

    User findUserById(Integer id);
}

14、UserMapper.xml(mybatis的文件)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<!-- 设置为IUserDao接口方法提供sql语句配置 -->
<mapper namespace="com.hdu.dao.UserMapper">

    <select id="findUserById" resultType="com.hdu.entity.User" parameterType="int">
        SELECT * FROM user WHERE id = #{id}
    </select>

</mapper>

15、entity类User

package com.hdu.entity;

public class User {
    private Integer id;
    private String  email;
    private String password;
    private String username;
    private String  role;
    private int status;
    private String  regIp;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getRole() {
        return role;
    }

    public void setRole(String role) {
        this.role = role;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public String getRegIp() {
        return regIp;
    }

    public void setRegIp(String regIp) {
        this.regIp = regIp;
    }
}

16、user.sql数据库

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '用户ID',
  `email` varchar(255) NOT NULL COMMENT '用户邮箱',
  `password` varchar(255) NOT NULL COMMENT '用户密码',
  `username` varchar(255) NOT NULL COMMENT '用户昵称',
  `role` varchar(255) NOT NULL COMMENT '用户身份',
  `status` int(1) NOT NULL COMMENT '用户状态',
  `regTime` datetime NOT NULL COMMENT '注册时间',
  `regIp` varchar(255) NOT NULL COMMENT '注册IP',
  PRIMARY KEY (`id`),
  UNIQUE KEY `email` (`email`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

17、咳咳，项目的主页index.jsp

<html>
<h2>Hello World!</h2>
<hr size="12" color="blue"/>
<form action="${pageContext.request.contextPath}/show/showUserById.do">
   id:<input type="text" name="id" id="id">
    <input type="submit" value="提交">
</form>
</body>
</html>

18、result.jsp

19、项目配置Tomcat一通跑，OVER
