mybatisplus calls oracle stored procedure

mybatisplus calls oracle stored procedure

Create a test oracle stored procedure

-- 创建携带返回值存储过程
CREATE OR REPLACE PROCEDURE SP_SUM_PROC_2023(number1 IN NUMBER, number2 IN NUMBER, result OUT NUMBER,result2 OUT NUMBER) is
BEGIN
result := number1 + number2;
result2 := 999;
END;

Use normal sql to call stored procedures

-- sql窗口中调用
DECLARE res NUMBER(6); res2 NUMBER(6);
BEGIN 
   SP_SUM_PROC_2023(1, 3, res,res2); 
  dbms_output.put_line(res);
  dbms_output.put_line(res2);
END; 

Use mybatis calling method

service layer call

    Map<String, Object> result = new HashMap<>();
    result.put("test", "asdfasdf");//这里是入参，必须输入
    result.put("errorCode", 0);// 这里是出参，随便写点东西
    result.put("errorCode2", 0);// 这里是出参，随便写点东西
    baseMapper.testTran(result);
    System.out.println("result = " + JsonUtil.toJSONString(result));

mapper interface

public interface MMapper {
    
    
    void testTran(Map<String, Object> result); // 这里没有@Param("result") 
}

mapper.xml file

...
<select id="testTran" statementType="CALLABLE" parameterType="map">
    call SP_SUM_PROC_2023(1,2,#{errorCode,mode=OUT,jdbcType=INTEGER},#{errorCode2,mode=OUT,jdbcType=INTEGER})
</select>

mode=OUT or IN, OUT is the parameter brought out, IN is the parameter passed into the stored procedure
