这里写的是后台数据库使用Mysql，

存储过程定义：

 1 PROCEDURE deyestest.procedure1(OUT json VARCHAR(2000))

 2 BEGIN DECLARE v_id        INT;

 3   DECLARE v_userName  VARCHAR(155);

 4   DECLARE v_mobileNum VARCHAR(55);

 5   DECLARE v_tmp       VARCHAR(1000);

 6   DECLARE v_info      VARCHAR(2000);

 7   DECLARE v_info2     VARCHAR(2000);

 8   DECLARE v_int       INT;

 9   

10 

11   DECLARE done        INT DEFAULT 0;

12 

13 

14   DECLARE myCursor CURSOR FOR

15   SELECT userId

16        , userName

17        , mobileNum

18   FROM

19     user_info

20   ORDER BY

21     userId

22   LIMIT

23     2, 10;

24   DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET done = 1;

25 

26   OPEN myCursor;

27   SET v_info = concat('[');

28   FETCH myCursor INTO v_id, v_userName, v_mobileNum;

29   REPEAT

30 

31     SET v_tmp = concat('{', v_id, ',', v_userName, ',', v_mobileNum, '}', ',');

32     SET v_info = concat(v_info, v_tmp);

33     FETCH myCursor INTO v_id, v_userName, v_mobileNum;

34   UNTIL done

35   END REPEAT;

36   SET NAMES 'utf8';

37   SET v_int = char_length(v_info);

38 

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

40 

41   SET v_info2 = concat(v_info, ']');

42   CLOSE myCursor;

43   SELECT v_info2

44 INTO

45   json;

46 END

View Code

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：

1 public interface PersonMapper {

2     public void getByProcedure2(Map<String,Object> map);

3 }

View Code

java调用测试

1 public  static void main(){

2 HashMap<String, Object> hashMap = new HashMap<String, Object>();

3         

4         wuShuaiMapper.getByProcedure2(hashMap);

5         System.out.println(hashMap.get("json"));

6 

7 }

View Code

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。
