JPA 2.1 @Procedure with multiple out parameters

问题

问题：调用带有多个输出参数的存储过程。

  1. @Procedure(procedureName = "procedureName", outputParameterName = "parma1", outputParameterName = "param2")
  2. Map<String, String> methodName();

在从服务类调用方法时，我遇到以下错误。

  1. Caused by: java.lang.IllegalArgumentException: Type cannot be null
  2.         at org.hibernate.query.procedure.internal.ProcedureParameterImpl.setHibernateType(ProcedureParameterImpl.java:130)

英文:

Issue: call procedure with multiple out parameters.

  1. @Procedure(procedureName = &quot;procedureName&quot; , outputParameterName = &quot;parma1&quot;, outputParameterName = &quot;param2&quot;)
  2. Map&lt;String, String&gt; methodName();

I am getting below error while calling method from service class.

以下是翻译好的内容：

在下方网址提供的详细信息中 http://roufid.com/3-ways-to-call-a-stored-procedure-with-hibernate-jpa-2-1/ 对我很有帮助。

按照以下方式手动注册存储过程。

// 动态存储过程定义。

  1. StoredProcedureQuery addBookStoredProcedure = entityManager.createStoredProcedureQuery("addBook_sp");
  2. addBookStoredProcedure.registerStoredProcedureParameter("sum", String.class, ParameterMode.OUT); 
  6. /// 调用存储过程并获取结果
  7. query.execute();
  8. Double sum = (Double) addBookStoredProcedure.getOutputParameterValue("sum");
英文:

Detail given below web link http://roufid.com/3-ways-to-call-a-stored-procedure-with-hibernate-jpa-2-1/ work for me.

Register the procedure manually as given below.

// Dynamic stored procedure definition.

  1. StoredProcedureQuery addBookStoredProcedure = entityManager.createStoredProcedureQuery(&quot;addBook_sp&quot;);
  2. addBookStoredProcedure.registerStoredProcedureParameter(&quot;sum&quot;, String.class, ParameterMode.OUT); 
  6. /// call the stored procedure and get the result
  7. query.execute();
  8. Double sum = (Double) addBookStoredProcedure.getOutputParameterValue(&quot;sum&quot;);
