Springboot工程Mybatis二级缓存配置

1、在application.yml配置cache-enabled: true

    mybatis:
      config-location: classpath:/mybatis-config.xml, classpath:mybatis/mybatis-config.xml
      mapper-locations: classpath:mappers/*.xml,classpath:mybatis/mapper/*.xml
      configuration:
        cache-enabled: true

2、在xxxMapper.xml添加 

　　　　　a)<cache></cache>
        
        b) <select id="selectBygoodsCataCodeAndprovinceCode" resultMap="BaseResultMap" useCache="true" >

3)实体对象要implements Serializable，否则报错

public class CompleteTime implements Serializable

4、启动工程，如果出现

Cache Hit Ratio . #表示缓存开启了.....
