【MybatisPlus】MybatisPlus开启二级缓存

@[TOC]

1、启动类增加开启缓存注解

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cache.annotation.EnableCaching;


@SpringBootApplication
// 开启缓存注解
@EnableCaching
public class StartApplication {

    public static void main(String[] args) {
        SpringApplication.run(StartApplication.class, args);
    }

}

2、mapper层接口加上缓存注解

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.CacheNamespace;
import org.apache.ibatis.annotations.Mapper;

@Mapper
@CacheNamespace
public interface UserMapper extends BaseMapper<User> {
}

3、yml配置

mybatis-plus:
  mapper-locations: classpath*:/mapper/*.xml
  configuration:
    cache-enabled: true #开启MybatisPlus的二级缓存

4、xml配置【可选】

如果你需要在XML文件中编写SQL代码，需要在XML文件中加上cache-ref标签，

<cache-ref namespace="com.xxx.mapper.UserMapper" />

5、注意项

增删改查操作都需要在一个命名空间下才可以；
