mybatis mysql 调用视图
java代码
@RequestMapping(value = "http://www.mamicode.com/testView", method = RequestMethod.GET) public @ResponseBody String testView(HttpServletRequest request, HttpServletResponse response) throws IOException { Map<String, Object> paraMap = new HashMap<String, Object>(); paraMap.put("userType", "doctor"); List<Map<String, Object>> list = new ArrayList<Map<String,Object>>(); list = procedureMapper.testView(paraMap); if(list != null && list.size() > 0){ for (int i = 0; i < list.size(); i++) { System.out.println(list.get(i)); } } return null; }
mapper
package cn.zsmy.mapper; import java.util.List; import java.util.Map; import cn.zsmy.entity.User; import cn.zsmy.form.UserForm; import cn.zsmy.mapper.base.SimpleMapper; import cn.zsmy.tmp.core.MyBatisRepository; /** * @ClassName: ProcedureMapper * @Description: 调用存储过程与视图 * @author 师海明 * @date 2016年6月13日 上午11:52:38 * */ @MyBatisRepository public interface ProcedureMapper extends SimpleMapper<UserForm,User>{ Map<String, Object> testProcedure(Map<String, Object> paraMap); List<Map<String, Object>> testView(Map<String, Object> paraMap); }
mapper.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="cn.zsmy.mapper.ProcedureMapper" > <!-- 调用存储过程查询 --> <select id="testProcedure" parameterType="java.util.Map" statementType="CALLABLE" resultType="java.util.HashMap"> {call loginandreg( #{out_ret,mode=OUT,javaType=java.lang.Integer,jdbcType=INTEGER}, #{out_desc,mode=OUT,javaType=java.lang.String,jdbcType=VARCHAR}, #{userId,jdbcType=VARCHAR,mode=OUT}, #{user_pwd,jdbcType=VARCHAR,mode=IN}, #{nickname,jdbcType=VARCHAR,mode=IN} ) } </select> <!-- 调用视图查询 --> <select id="testView" parameterType="java.util.Map" resultType="java.util.HashMap"> select username, nickname, dept from test_view where user_type=#{userType} </select> </mapper>
视图
DROP VIEW IF EXISTS `palm_2_0_16`.`test_view`; CREATE VIEW `palm_2_0_16`.`test_view` AS SELECT u.username,u.nickname,d.dept, u.user_type FROM tb_user u, tb_doctor d WHERE d.id=u.id ;
备注:
mapper.xml中where后面的参数条件一定是在视图中返回的,不然会报错。
