这样一个p2p项目的骨架就完成了,接下来实现一个注册的功能

在core下编写domain,mapper,service

domain 

package cn.wolfcode.p2p.domain;

import java.io.Serializable;

/**
 * Create by CrazyCat
 */


public class BaseDomain implements Serializable {
    private Long id;
}


package cn.wolfcode.p2p.domain;


import lombok.Getter;
import lombok.Setter;

@Setter
@Getter
public class LoginInfo extends BaseDomain{
    public static final int STATE_NORMAL=0;//正常情况

    public static final int STATE_LOCK=1;//锁定

    private String username;

    private String password;

    private int state;
}

mapper 

package cn.wolfcode.p2p.mapper;

import cn.wolfcode.p2p.domain.LoginInfo;
import java.util.List;

public interface LoginInfoMapper {


    int insert(LoginInfo record);

    LoginInfo selectByPrimaryKey(Long id);

    int updateByPrimaryKey(LoginInfo record);

    int checkRegister(String username);
}

mapper.xml 

<?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" >
<mapper namespace="cn.wolfcode.p2p.mapper.LoginInfoMapper" >
  <resultMap id="BaseResultMap" type="cn.wolfcode.p2p.domain.LoginInfo" >
    <id column="id" property="id" jdbcType="BIGINT" />
    <result column="username" property="username" jdbcType="VARCHAR" />
    <result column="password" property="password" jdbcType="VARCHAR" />
    <result column="state" property="state" jdbcType="TINYINT" />
  </resultMap>

  <insert id="insert" parameterType="cn.wolfcode.p2p.domain.LoginInfo" useGeneratedKeys="true" keyProperty="id" >
    insert into logininfo (username, password, state
      )
    values (#{username,jdbcType=VARCHAR}, #{password,jdbcType=VARCHAR}, #{state,jdbcType=TINYINT}
      )
  </insert>
  <update id="updateByPrimaryKey" parameterType="cn.wolfcode.p2p.domain.LoginInfo" >
    update logininfo
    set username = #{username,jdbcType=VARCHAR},
      password = #{password,jdbcType=VARCHAR},
      state = #{state,jdbcType=TINYINT}
    where id = #{id,jdbcType=BIGINT}
  </update>
  <select id="selectByPrimaryKey" resultMap="BaseResultMap" parameterType="java.lang.Long" >
    select id, username, password, state
    from logininfo
    where id = #{id,jdbcType=BIGINT}
  </select>
  <select id="checkRegister" resultType="java.lang.Integer">
    select count(id)
    from logininfo
    where username=#{username}
  </select>

</mapper>

service 

package cn.wolfcode.p2p.service;

import cn.wolfcode.p2p.domain.LoginInfo;

/**
 * Created by CrazyCat on 2018/3/8.
 */


public interface ILoginInfoService {
    int insert(LoginInfo record);

    LoginInfo selectByPrimaryKey(Long id);

    int updateByPrimaryKey(LoginInfo record);

    void checkResgister(String username,String password);
}


package cn.wolfcode.p2p.service.impl;

import cn.wolfcode.p2p.domain.LoginInfo;
import cn.wolfcode.p2p.mapper.LoginInfoMapper;
import cn.wolfcode.p2p.service.ILoginInfoService;
import cn.wolfcode.p2p.utils.MD5;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

/**
 * Created by CrazyCat on 2018/3/8.
 */
@Service
@Transactional
public class LoginInfoServiceImpl implements ILoginInfoService {

    @Autowired
    private LoginInfoMapper loginInfoMapper;

    @Override
    public int insert(LoginInfo record) {
        return loginInfoMapper.insert(record);
    }

    @Override
    public LoginInfo selectByPrimaryKey(Long id) {
        return loginInfoMapper.selectByPrimaryKey(id);
    }

    @Override
    public int updateByPrimaryKey(LoginInfo record) {
        return loginInfoMapper.updateByPrimaryKey(record);
    }

    @Override
    public void checkResgister(String username,String password) {
        int count = loginInfoMapper.checkRegister(username);
        if(count>0){
            throw new RuntimeException("该用户已注册,请重新输入");
        }
        LoginInfo entity = new LoginInfo();
        entity.setUsername(username);
        entity.setPassword(MD5.encoder(password));
        loginInfoMapper.insert(entity);


    }
}

utils 

package cn.wolfcode.p2p.utils;

import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;


/**
 * @author Rz
 * @date 26/02/2018 21:41
 */
@Getter
@AllArgsConstructor @NoArgsConstructor
public class JSONResult {
    private boolean success = true;
    private String msg;


    public JSONResult setMsg(boolean success,  String msg) {
        this.success = success;
        this.msg = msg;
        return this;
    }
}

Config.class 

package cn.wolfcode.p2p;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.transaction.annotation.Transactional;

import javax.sql.DataSource;

/**
 * Created by CrazyCat on 2018/3/8.
 */

@Configuration
@MapperScan("cn.wolfcode.p2p.mapper")
@PropertySource("application-core.properties")
@EnableTransactionManagement
public class CoreConfig {


    public static void main(String[] args) {
        SpringApplication.run(CoreConfig.class,args);
    }

}

application-core.properties 

spring.datasource.druid.username=root
spring.datasource.druid.password=admin
spring.datasource.druid.url=jdbc:mysql:///p2p
spring.datasource.druid.driver-class-name=com.mysql.jdbc.Driver

website部分

controller 

package cn.wolfcode.p2p.controller;

import cn.wolfcode.p2p.service.ILoginInfoService;
import cn.wolfcode.p2p.utils.JSONResult;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * Created by CrazyCat on 2018/3/8.
 */

@Controller
public class RegisterController {

    @Autowired
    private ILoginInfoService loginInfoService;


    @RequestMapping("checkRegister")
    @ResponseBody
    public Object checkRegister(String username,String password){
        JSONResult result = new JSONResult();
        try{
            loginInfoService.checkResgister(username,password);
            result.setMsg(true,"注册成功");
        }catch(Exception e){
            result.setMsg(false,e.getMessage());
        }
        return result;
    }
}

config.class 

package cn.wolfcode.p2p;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

/**
 * Created by CrazyCat on 2018/3/8.
 */

@SpringBootApplication
public class WebConfig {

    public static void main(String[] args) {
        SpringApplication.run(WebConfig.class,args);
    }
}

也需要一个application.properties资源文件，可以不配置参数，也可以在这里修改端口

register.html 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>注册</title>
</head>
<body>
    <form action="/checkRegister" method="post">
        <input type="text" name="username"/><br/>
        <input type="text" name="password"/><br/>
        <input type="submit" value="提交"/>
    </form>
</body>
</html>

如何数据库没有这条数据，效果如下：
