Maven+SSM(Spring+SpringMVC+Mybatis)实现登录功能

一 用IDEA构建一个空的Maven web项目

重点截图：

然后下一步直到完成（设置项目名和maven地址）

二 搭建环境

1 添加依赖

2 建立对应的目录文件夹

3 写配置文件

db.properties

#数据源的配置信息
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/testweb?characterEncoding=utf-8
jdbc.username=root
jdbc.password=root

log4j.properties

log4j.rootLogger=DEBUG, stdout
log4j.appender.CONSOLE.Encoding=UTF-8

log4j.appender.stdout.layout.ConversionPattern=%d[%t]%-5p[%c]-%m%n

写登录实例

Person.java

package com.manage.model;

public class Person {
    private Long id;

    private String username;

    private String password;

    public Long getId() {
        return id;
    }

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


    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username == null ? null : username.trim();
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password == null ? null : password.trim();
    }
}

PersonMapper接口

package com.manage.dao;

import com.manage.model.Person;
import org.apache.ibatis.annotations.*;

public interface PersonMapper {

    Person select(@Param("name") String name, @Param("age") int age);

}

mapper文件

<mapper namespace="com.manage.dao.PersonMapper">

    <resultMap id="person" type="Person">
        <result property="username" column="name">result>
        <result property="password" column="age">result>
    resultMap>

    <select id="select" resultMap="person">
        SELECT * FROM tuser WHERE name=#{name} AND age=#{age}
    select>
mapper>

service接口

package com.manage.service;

import com.manage.model.Person;

public interface TestService {

    public Person login(String name,int age);
}

service实现类

package com.manage.service.impl;

import org.springframework.beans.factory.annotation.Autowired;

    @Autowired
    private PersonMapper personMapper;

    public Person login(String name, int age) {
        return personMapper.select(name,age);
    }
}
