如何在客户端为 GWT 使用 JAXB 注释? [英] How to use JAXB annotations in the client side for GWT?

问题描述

我想像这样在我的班级中使用 JaxB 注释:

I wanted to use the JaxB annotation in my class like this:

@XmlRootElement
public class ItemExtension implements Serializable {

但是当我把它放在客户端时 GWT 会抱怨.

But GWT complains when I put it in the client side.

 [ERROR] Line 4: The import javax.xml.bind cannot be resolved
         [ERROR] Line 14: XmlRootElement cannot be resolved to a type

是否有解决方法或我做错了什么?

Is there a workaround or am I doing something wrong?

推荐答案

我有一个项目，它在客户端 GWT 代码中使用带有 JPA 和 JAXB 注释的实体类.请参阅GWT 文档.

I have a project that uses entity classes with both JPA and JAXB annotations in the client-side GWT code. See the section "Overriding one package implementation with another" in the GWT Documentation.

假设您的模块位于 com.example.app 包中.您需要在新包中重新创建[1] 所有 JAXB 注释类，特别是 com.example.app.jre.java.xml.bind.annotation；在您的模块 XML 文件中，然后添加 <super-source path="jre"/> 并设置.

Let's say your module is in package com.example.app. You will need to recreate[1] all JAXB annotation classes in a new package, specifically com.example.app.jre.java.xml.bind.annotation; in your module XML file, you then add <super-source path="jre" /> and you're set.

请注意，您不需要分发该包中的类文件，它们只是为了 GWT 编译器而需要.

Note that you don't need to distribute the class files in that package, they are needed solely for the sake of the GWT compiler.

[1]:您可以复制它们并调整所有包引用.
