我下载了xstream jar和sourcecode，并使用 winrar 将源代码附加到jar文件中
我创建了2个gwt.xml文件。
xstream.gwt.xml存在于com.thoughtworks
中<?xml version="1.0" encoding="UTF-8"?>
<module>
<source path="xstream"/>
</module>
和operations.gwt.xml存在于com.thoughworks.xstream
中<?xml version="1.0" encoding="UTF-8"?>
<module>
<source path="annotations"/>
<source path="converters"/>
<source path="core"/>
<source path="io"/>
<source path="mapper"/>
<source path="persistence"/>
</module>
编辑：我的gwt项目xml
<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='test'>
<inherits name='com.google.gwt.user.User'/>
<inherits name='com.google.gwt.user.theme.standard.Standard'/>
<inherits name='com.thoughtworks.xstream'/>
<entry-point class='com.example.test.client.Index'/>
</module>
但我收到了错误
Compiling module com.example.test.Test

答案 0 :(得分：3)
你不能在GWT中使用反射;
getDeclaredFields
getDeclaredMethod
的forName
getConstructor
和喜欢......都是反思性呼叫;
答案 1 :(得分：0)
GWt不支持客户端的所有代码，因此我们可以在服务器中使用它。 GWT支持RPC。 http://www.vogella.com/articles/GWT/article.html或参考 https://developers.google.com/web-toolkit/doc/latest/DevGuideServerCommunication
你需要做的是在lib中包含所有jar并配置构建路径，并且只在服务器端使用此代码。
