具有多个输出参数的 JPA 2.1 @Procedure
JPA 2.1 @Procedure with multiple out parameters
问题:具有多个输出参数的调用过程。
@Procedure(procedureName = "procedureName" , outputParameterName = "parma1", outputParameterName = "param2")
Map<String, String> methodName();
我在从服务 class 调用方法时出现以下错误。

下面给出的详细信息 link http://roufid.com/3-ways-to-call-a-stored-procedure-with-hibernate-jpa-2-1/ 对我有用。
如下所示手动注册程序。
//动态存储过程定义。
StoredProcedureQuery addBookStoredProcedure = entityManager.createStoredProcedureQuery("addBook_sp");
addBookStoredProcedure.registerStoredProcedureParameter("sum", String.class, ParameterMode.OUT);
/// call the stored procedure and get the result
query.execute();
Double sum = (Double) addBookStoredProcedure.getOutputParameterValue("sum");
