?創建實體類

• 這里使用的@Getter和@Setter注解，可以避免寫一大堆的get和set方法
• 需要引入Lombak，在file->settings->plugins里面查找

package com.cc.springbootrediscache.entity;import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
public class User {private Integer id;private String username;private String password;private Integer status;public User(String username, String password, Integer status) {this.username = username;this.password = password;this.status = status;}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public Integer getStatus() {return status;}public void setStatus(Integer status) {this.status = status;}
}

UserMapper

package com.cc.springbootrediscache.mapper;import com.cc.springbootrediscache.entity.User;
import org.apache.ibatis.annotations.*;import java.util.List;public interface UserMapper {@Options(useGeneratedKeys = true, keyProperty = "id")@Insert("insert into user (username,password,status) values (#{username}, #{password}, #{status})")Integer addUser(User user);@Delete("delete from user where id=#{0}")Integer deleteUserById(Integer id);@Update("update user set username=#{username}, password=#{password}, status=#{status}")Integer updateUser(User user);@Select("select * from user where id=#{0}")User getById(Integer id);@Select("select * from user")List<User> queryUserList();}

UserService?

package com.cc.springbootrediscache.service;import com.cc.springbootrediscache.entity.User;
import com.cc.springbootrediscache.mapper.UserMapper;
import org.springframework.cache.annotation.CacheEvict;
import org.springframework.cache.annotation.CachePut;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;import javax.annotation.Resource;@Service
public class UserService {@Resourceprivate UserMapper userMapper;/*** 添加和更新都調用這個方法* @param user* @return user_1*/@CachePut(value = "usercache", key = "'user_' + #user.id.toString()", unless = "#result eq null")public User save(User user) {if (null != user.getId()) {userMapper.updateUser(user);} else {userMapper.addUser(user);}return user;}@Cacheable(value = "usercache", key = "'user_' + #id", unless = "#result eq null")public User findUser(Integer id) {return userMapper.getById(id);}@CacheEvict(value = "usercache", key = "'user_' + #id", condition = "#result eq true")public boolean delUser(Integer id) {return userMapper.deleteUserById(id) > 0;}
}

?UserController

package com.cc.springbootrediscache.controller;import com.cc.springbootrediscache.entity.User;
import com.cc.springbootrediscache.service.UserService;
import org.springframework.web.bind.annotation.*;import javax.annotation.Resource;@RestController
@RequestMapping("/user")
public class UserController {@Resourceprivate UserService userService;@PutMappingpublic User add(@RequestBody User user) {return userService.save(user);}@DeleteMapping("{id}")public boolean delete(@PathVariable Integer id) {return userService.delUser(id);}@GetMapping("{id}")public User getUser(@PathVariable Integer id) {return userService.findUser(id);}@PostMappingpublic User update(@RequestBody User user) {return userService.save(user);}
}

使用MapperScan添加對于mapper的掃描

package com.cc.springbootrediscache;import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
@MapperScan("com.cc.springbootrediscache.mapper")
public class SpringbootRedisCacheApplication {public static void main(String[] args) {SpringApplication.run(SpringbootRedisCacheApplication.class, args);}
}
