springboot中使用springboot cache
前言：SpringBoot中使用Cache缓存可以提高对缓存的开发效率
此图片是SpringBootCache常用注解
第一步：引入依赖
<!--缓存--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-cache</artifactId></dependency><!--redis--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency>第二步：在启动类添加@EnableCachin
@EnableCaching //开启缓存注解功能
第三步：在实体类上继承序列化接口
public class User implements Serializable 
第四步：使用注解
@PostMapping("/add")@CachePut(cacheNames = "userCache",key = "#user.id") //缓存数据public User addInfo(@RequestBody User user){boolean save = userService.save(user);return user;}@GetMapping("/get/{id}")@Cacheable(cacheNames = "userCache", key = "#id") //查询redis中是否存储的有数据，有数据直接返回，没有数据前往MySQL查询数据public User getUser(@PathVariable Integer id){return userService.getById(id);}@DeleteMapping("/del/{id}")@CacheEvict(cacheNames = "userCache",key = "#id") //删除数据的时候同时删除缓存数据public void delUser(@PathVariable Integer id){userService.removeById(id);}@DeleteMapping("/delAll")@CacheEvict(cacheNames = "userCache",allEntries = true) //删除全部数据的时候同时删除缓存中全部数据public void delUser(){userService.deleteAll();}
