如何从spring data JPA调用存储过程procedure，其中procedure等于

【解决方案1】：

尝试如下：

实体类

@Entity

@NamedStoredProcedureQuery(name = "User.plus1", procedureName = "plus1inout", parameters = {

  @StoredProcedureParameter(mode = ParameterMode.IN, name = "arg", type = Integer.class),

  @StoredProcedureParameter(mode = ParameterMode.OUT, name = "res", type = Integer.class) 

})

public class User {}

存储库方法应该是这样的

@Procedure("plus1inout")
Integer explicitlyNamedPlus1inout(Integer arg);
