第三步：配置文件如下： pom.xml文件配置：

4.0.0org.springframework.bootspring-boot-starter-parent2.4.5 com.weidemo010.0.1-SNAPSHOTdemo01Demo project for Spring Boot1.8 org.springframework.bootspring-boot-starter-jdbcorg.springframework.bootspring-boot-starter-thymeleaforg.springframework.bootspring-boot-starter-weborg.mybatis.spring.bootmybatis-spring-boot-starter2.1.0 mysqlmysql-connector-java8.0.24runtimeorg.springframework.bootspring-boot-starter-testtestjunitjunittest org.projectlomboklomboktrue org.springframework.bootspring-boot-maven-pluginorg.projectlomboklombok

application.properties文件配置：

#改变端口号:server.port=8080#给整个项目加个前缀,多个项目就不会重复：#server.servlet.context-path=/first#school.grade=3#school.classNum=4 spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driverspring.datasource.password=rootspring.datasource.username=rootspring.datasource.url=jdbc:mysql://localhost:3306/demo?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=truespring.thymeleaf.prefix=classpath:/templates/#mapper.mappers=tk.mybatis.mapper.common.Mapper#mapper.not-empty=true

LoginController.java文件：
注意：@Controller只能用这个，不能用@RestController

package com.wei.demo01.controller; import com.wei.demo01.entity.UserBean; import com.wei.demo01.service.UserService; import lombok.extern.slf4j.Slf4j; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import javax.annotation.Resource; @Slf4j@Controllerpublic class LoginController { //将Service注入Web层@ResourceUserService userService; //实现登录@RequestMapping("/login")public String show(){return "login"; } @RequestMapping(value = "https://www.it610.com/loginIn",method = RequestMethod.POST)public String login(String name,String password){UserBean userBean = userService.LoginIn(name, password); log.info("name:{}",name); log.info("password:{}",password); if(userBean!=null){return "success"; }else {return "error"; }}@RequestMapping("/signup")public String disp(){return "signup"; } //实现注册功能@RequestMapping(value = "https://www.it610.com/register",method = RequestMethod.POST)public String signUp(String name,String password){userService.Insert(name, password); return "success"; }}

UserBean.java文件

package com.wei.demo01.entity; import java.io.Serializable; public class UserBean implements Serializable { private Integer id; private String name; private String password; public Integer getId() {return id; } public void setId(Integer id) {this.id = id; } public String getName() {return name; } public void setName(String name) {this.name = name; } public String getPassword() {return password; } public void setPassword(String password) {this.password = password; }}

UserMapper接口文件：
注意：我在这里为偷懒，开始加入了@Mapper注解，目的就是为了不再写mapper映射文件（那个xml写的是真的是太慢了）

package com.wei.demo01.mapper; import com.wei.demo01.entity.UserBean; import org.apache.ibatis.annotations.Insert; import org.apache.ibatis.annotations.Mapper; import org.apache.ibatis.annotations.Param; import org.apache.ibatis.annotations.Select; import org.springframework.stereotype.Component; import org.springframework.stereotype.Repository; @Mapperpublic interface UserMapper {//查询，可以实现登录功能@Select("SELECT * FROM user WHERE name = #{name} AND password = #{password}")UserBean getInfo(@Param("name") String name, @Param("password") String password); //多个参数要加@Param修饰//增加，可以实现注册功能@Insert("insert into user(name,password)values(#{name},#{password})")void saveInfo(@Param("name") String name, @Param("password") String password); }

UserService.java文件

package com.wei.demo01.service; import com.wei.demo01.entity.UserBean; import com.wei.demo01.mapper.UserMapper; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import javax.annotation.Resource; @Servicepublic class UserService {//将dao层属性注入service层@Resourceprivate UserMapper userMapper; public UserBean LoginIn(String name, String password) {return userMapper.getInfo(name,password); } public void Insert(String name,String password){userMapper.saveInfo(name, password); }}
