Question

我需要JAXB中的这个问题的帮助，而我运行项目时总是得到以下错误

Property assignment is present but not specified in @XmlType.propOrder
this problem is related to the following location: 
  at public int edu.asu.cse446.sample1.server.test.GradBook.getAssignment()
  at edu.asu.cse446.sample1.server.test.GradBook

这是我的代码：

 package edu.asu.cse446.sample1.server.test;

    @XmlElement                 // Read it in XML Format

Answer 1

好。这就是为什么他们说 - follow standard and conventions。

问题是 - 您将成员变量名称大写。

将它们更改为 - "id", "assignment", "midTerm", "quiz", "classLab"，它应该有用。
