使用MyBatis调用oracle函数（基于注释）

Question

我需要使用注解在MyBatis中调用Oracle函数。

我的映射：

@Select("{ CALL #{outParam, jdbcType=NUMERIC, mode=OUT} := ORA_FUNC(" 
    + "#{pNum1, jdbcType=NUMERIC, mode=IN}," 
    + "#{pNum2, jdbcType=NUMERIC, mode=IN}," 
    + "#{pNum3, jdbcType=NUMERIC, mode=IN})}") 
@Options(statementType = StatementType.CALLABLE) 
@ResultType(Integer.class) 
public Integer executeFunction(
    @Param("map") Map<String, Object> carteira); 

我呼吁这个签名：

Map<String, Object> mapParameters = new HashMap<String, Object>(); 
mapParameters.put("pNum1", carteira.getUnimedCarteira()); 
mapParameters.put("pNum2", carteira.getCodCarteira()); 
mapParameters.put("pNum3", carteira.getDigitoCarteira()); 
mapper.obterRedeBeneficiario(mapParameters); 
return mapParameters.get("outParam").toString(); 

的outParam为null，并且映射器的返回是空过。

任何人都可以帮助我吗？

Answer 1

创建一个域类分拆类

class SpInOut{ 

    private String outParam; 
    private int pNum1; 
    private int pNum2; 
    private int pNum3; 

    //Getters and setters 

} 

，你可以改变你的maaper如下

@Select("{ #{outParam, jdbcType=NUMERIC, mode=OUT} = CALL ORA_FUNC(" 
    + "#{pNum1, jdbcType=NUMERIC, mode=IN}," 
    + "#{pNum2, jdbcType=NUMERIC, mode=IN}," 
    + "#{pNum3, jdbcType=NUMERIC, mode=IN})}") 
@Options(statementType = StatementType.CALLABLE) 
public void executeFunction(
    SpInOut inOut);
