tkmybatis开启二级缓存

1.MyBatis配置文件开启二级缓存功能 

<settings> 
<settingname="cacheEnabled"value="true"/> 
</settings>

2.在 XxxMapper 接口上使用@CacheNamespace 注解 

@CacheNamespace
 public interface EmployeeMapper extends MyMapper<Employee>{

}

3.实体类上实现序列化

public class Employee implements Serializable {
	
	private static final long serialVersionUID = 1L;
