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.....
