spring boot redis做mybatis二級快取

• 新增依賴

  <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
  <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-cache</artifactId>
    </dependency>
  複製程式碼

• application.properties

  spring.redis.host=127.0.0.1
  spring.redis.pool.max-idle=8
  spring.redis.pool.min-idle=0
  spring.redis.pool.max-active=8
  spring.redis.pool.max-wait=-1

• Aplication

    @SpringBootApplication
    @EnableCaching
    public class Application {
  
        public static void main(String[] args) {
            SpringApplication.run(Application.class,args);
        }
    }

• mapper

    @Component  //為了消除Controller裡面的紅線警告
    @Mapper
    @CacheConfig(cacheNames = "users")
    public interface UserMapper {
    
        @Cacheable
        User get(Long id);
    
        void insert(User user);
        void update(User user);
        List<User> list(UserQueryObject qo);
        void delete(Long id);
        User findByUsername(String username);
        Set<String> getRoleNamesByUserId(Long userId);
        Set<String> getPermissionsNameByRoleNames(@Param("roleNames") Set<String> roleNames);
    }

在需要快取的地方新增@Cacheable註解
