使用注解操作

package com.chen.dao;import com.chen.bean.Action;
import org.apache.ibatis.annotations.InsertProvider;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;import java.util.List;
import java.util.Map;@Repository
public interface ActionDao {<!----- 直接查询 ---->@Select("select * from tbl_action where id>#{id}")List<Action> findActionById(@Param("id") Integer id);<!----  用构造器 --->@InsertProvider(type = com.chen.dao.ActionSqlProvider.class,method = "insertAction")int insert(Action a);}

查询构造器 ActionSqlProvider

package com.chen.dao;import com.chen.bean.Action;
import org.apache.ibatis.jdbc.SQL;public class ActionSqlProvider {public String insertAction(final Action action){return  new SQL(){{INSERT_INTO("tbl_action");if(action.getName() != null){VALUES("name","#{name}");}if(action.getCreate_time() != null){VALUES("create_time","#{create_time}");}if(action.getLog() != null){VALUES("log","#{log}");}if(action.getStatus() != null){VALUES("status","#{status}");}if(action.getUpdate_time() != null){VALUES("update_time","#{update_time}");}}}.toString();}
