这里写的是后台数据库使用Mysql，

存储过程定义：

 PROCEDURE deyestest.procedure1(OUT json VARCHAR(2000))
 BEGIN DECLARE v_id        INT;
   DECLARE v_userName  VARCHAR(155);
   DECLARE v_mobileNum VARCHAR(55);
   DECLARE v_tmp       VARCHAR(1000);
   DECLARE v_info      VARCHAR(2000);
   DECLARE v_info2     VARCHAR(2000);
   DECLARE v_int       INT;

   DECLARE done        INT DEFAULT 0;

   DECLARE myCursor CURSOR FOR
   SELECT userId
        , userName
        , mobileNum
   FROM
     user_info
   ORDER BY
     userId
   LIMIT
     2, 10;
   DECLARE CONTINUE HANDLER FOR SQLSTATE '' SET done = 1;

   OPEN myCursor;
   SET v_info = concat('[');
   FETCH myCursor INTO v_id, v_userName, v_mobileNum;
   REPEAT

     SET v_tmp = concat('{', v_id, ',', v_userName, ',', v_mobileNum, '}', ',');
     SET v_info = concat(v_info, v_tmp);
     FETCH myCursor INTO v_id, v_userName, v_mobileNum;
   UNTIL done
   END REPEAT;
   SET NAMES 'utf8';
   SET v_int = char_length(v_info);

   SET v_info = left(v_info COLLATE utf8_bin, v_int - 1);

   SET v_info2 = concat(v_info, ']');
   CLOSE myCursor;
   SELECT v_info2
 INTO
   json;
 END

java中Mapper配置：

<select id="getByProcedure2"  statementType="CALLABLE">

        {
            call procedure1(

             #{json,jdbcType=VARCHAR,javaType=java.lang.String,mode=OUT}
            )
        }
</select>

javaMapper代码：

 public interface PersonMapper {
     public void getByProcedure2(Map<String,Object> map);
 }

java调用测试

 public  static void main(){
 HashMap<String, Object> hashMap = new HashMap<String, Object>();

         wuShuaiMapper.getByProcedure2(hashMap);
         System.out.println(hashMap.get("json"));

 }

如果使用Map作为进行java与数据库存储过程的数据输入与输出的参数，只需要配置select标签中“statementType="CALLABLE"”，然后在存储过程中的输出参数使用如下方式：SELECT v_info2 INTO json，其中json是存储过程中的输出参数。
