Xstream XML到对象vonversion java.lang.NoClassDefFoundError：无法初始化类net.sf.cglib.proxy.Enhancer

Question

大家下午好，

Xstream jar出现问题。 我正在编写独立的后台流程，该流程会将XML转换为对象。 它在使用jdk1.6.0_35的eclipse中工作，我创建了jar文件，并使用jdk1.6.27将其部署在服务器中。

错误是

java.lang.NoClassDefFoundError: Could not initialize class net.sf.cglib.proxy.Enhancer

可能是什么问题？ 提前致谢。

我已将我的JDK复制到服务器，并尝试了相同的结果。

XStream xstream1 = new XStream(new StaxDriver()); 

//I tried both Stax and DOM Drivers same result 

XStream xstream1 = new XStream(new DomDriver()); //Same result. 

xstream1.alias("custom01", ConversionXstreamHelper.class);
//binding between xml elements and class and variables, 
................ 
ConversionXstreamHelper helper = (ConversionXstreamHelper)xstream1.fromXML(line);

Answer 1

我能够解决这个问题。 Xstream与CGLIB有关，我已将CGLIB-NODEP jar文件添加到我的maven构建中并构建了Jar，它的工作原理

我正在使用XStream 1.3 jar和cglib-nodep2.1_3.jar文件。

谢谢，
