JAVA 操作mysql 存储 调用

HashMap map = new HashMap();
map.put("a", 9);
map.put("b", "");

List<Map> mapTestOut = userService.proTestOut(map);
List<Map> mapTestIn = userService.proTestIn(map);

mybatis:
　　 <!-- 存储并输出 -->
    <select id="proTestOut" statementType="CALLABLE" parameterType="java.util.HashMap" resultType="java.util.Map">
        {call test_crud(#{a,jdbcType=INTEGER,mode=IN},
                       #{b,mode=OUT,jdbcType=INTEGER} )}
    </select>
    <!-- 存储没有输出函数 -->
    <select id="proTestIn" statementType="CALLABLE" parameterType="java.util.HashMap" resultType="java.util.Map">
        {call test_crud1(#{a,jdbcType=INTEGER,mode=IN})}
    </select>
