项目描述
本项目为javaweb课程设计作业，开发了一个类似于豆瓣读书的书友交流网站。
效果图
项目结构
mapper和pojo可以用generator自动生成，我们只需编写controller就可以了
贴一个userController的代码，其他的都大同小异
package com.tedu.aireading.controller;import java.util.List;
import java.util.Random;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import com.tedu.aireading.mapper.UserMapper;
import com.tedu.aireading.pojo.BookExample.Criteria;
import com.tedu.aireading.pojo.User;
import com.tedu.aireading.pojo.UserExample;@RestController
public class UserController {@AutowiredUserMapper userMapper;@RequestMapping("/user/test")public String test() {return "测试";}//登录/注册函数，输入用户名、密码//若用户名已存在则为登录，判断密码；若不存在进行注册//注册或登陆成功返回id，否则返回失败@RequestMapping("/user/registOrLogin")public String registOrLogin(String userName,String password) {UserExample userExample=new UserExample();UserExample.Criteria criteria = userExample.createCriteria();criteria.andUserNameEqualTo(userName);List<User> list=userMapper.selectByExample(userExample);if(list==null||list.size()==0) {//注册String str="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";Random random=new Random();StringBuffer sb=new StringBuffer();for(int i=0;i<6;i++){int number=random.nextInt(62);sb.append(str.charAt(number));}User user=new User();user.setUserId(sb.toString());user.setUserName(userName);user.setPassword(password);if(userMapper.insert(user)>0) return "register";}else {User user=list.get(0);if(user.getPassword().equals(password))//登录成功return user.getUserId().toString();}return "failed";}@RequestMapping("/user/exit")public String exit(String userId) {return "1";}
}
application.yml写法
server:port: 6000
spring:application:#typeservice前面必须有一个空格name: readservicedatasource:driver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://127.0.0.1:3306/aireading?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTCusername: rootpassword: rootmybatis:mapperLocations: classpath:com.tedu.aireading.mapper/*.xmllogging:level: com.tedu.aireading: debug
