最近，有个开发提了个需求，希望中间件支持调用mysql存储过程时支持多结果集返回，因为某些原因我们使用了不少的存储过程，很多复杂的逻辑目前来看交互非常的多，所以从当前的现状来说，这个需求还是蛮合理的。中午抽空特地搜了下，整合完整示例如下：
1、创建测试存储过程
delimiter $$ CREATE PROCEDURE sp_multi_resultset(IN p_operator_company_no int, IN p_operator_no int, OUT p_error_code varchar(32), OUT p_error_info varchar(255)) BEGIN select 1 as col1,2 as col2; select 11 as col11,22 as col21; end $$ delimiter ; call sp_multi_resultset(1,1,@error_code,@error_info);
2、mapper文件
<?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="MultiResultset"> <resultMap type="test.Test" id="test1"> <result column="col1" jdbcType="INTEGER" javaType="Integer" /> <result column="col2" jdbcType="INTEGER" javaType="Integer" /> </resultMap> <resultMap type="test.Test2" id="test2"> <result column="col1" jdbcType="INTEGER" javaType="Integer" /> <result column="col3" jdbcType="INTEGER" javaType="Integer" /> </resultMap> <select id="getTests" statementType="CALLABLE" parameterType="Map" resultMap="test1,test2" > {call sp_multi_resultset(#{param1,mode=IN,jdbcType=INTEGER},#{param2,mode=IN,jdbcType=INTEGER},#{errorCode,mode=OUT,jdbcType=VARCHAR},#{errorInfo,mode=OUT,jdbcType=VARCHAR})} </select> </mapper>

3、java代码
/** * */ package com.medsoft.top10.dao; import java.util.HashMap; import java.util.List; import java.util.Map; import org.mybatis.spring.SqlSessionTemplate; import org.springframework.beans.factory.InitializingBean; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.cyl.kernel.util.JsonUtils; /** * @author zhjh256@163.com * {@link} http://www.cnblogs.com/zhjh256 */ @Service public class TestMultiResultSet implements InitializingBean { @Autowired private SqlSessionTemplate sqlSession; /* (non-Javadoc) * @see org.springframework.beans.factory.InitializingBean#afterPropertiesSet() */ @Override public void afterPropertiesSet() throws Exception { Map<String,String> map = new HashMap<String,String>(); map.put("param1", "1"); map.put("param2", "1"); map.put("errorCode", ""); map.put("errorInfo", ""); List<List<?>> multiResult = sqlSession.selectList("MultiResultset.getTests",map); System.out.println(JsonUtils.toJson(multiResult.get(0))); System.out.println(JsonUtils.toJson(multiResult.get(1))); } }
输出：
[null]
[null]
说明压根没返回啊。。。这网上一个个都出来的，到底是测没测试呢。。。。难不成是spring-mybatis给阉割了，用原生mybatis看看。
