jpa 调用oracle 有out的存储过程报错 只有int的就没问题?报错

oracle创建存储过程

create or replace procedure PT(a in int,b out int)
    is
    BEGIN
        b :=1;
         dbms_output.put_line(b);
    END;
    /

实体类

@NamedStoredProcedureQuery(name="test", procedureName = "PT",parameters= {
        @StoredProcedureParameter(mode=ParameterMode.IN,type=int.class, name="a"),
        @StoredProcedureParameter(mode=ParameterMode.OUT,type=int.class, name="b")
})

Reponsitory

@Procedure(name="test")
int createPolicy(@Param("a")int a);

调用后报错:

org.springframework.dao.InvalidDataAccessApiUsageException: OUT/INOUT parameter not available: b; nested exception is java.lang.IllegalArgumentException: OUT/INOUT parameter not available: b

意思缺少b这个参数

Reponsitory  加上参数b后报错

org.springframework.dao.InvalidDataAccessApiUsageException: Can only bind values for IN/INOUT parameters : org.hibernate.query.procedure.internal.ProcedureParameterImpl@101c15ad; nested exception is java.lang.IllegalStateException: Can only bind values for IN/INOUT parameters : org.hibernate.query.procedure.internal.ProcedureParameterImpl@101c15ad
