com.thoughtworks.xstream.converters.ConversionException [英] com.thoughtworks.xstream.converters.ConversionException

问题描述

我正在开发的项目是Java J2EE中的3个文件夹项目，其中包含servlets和Hibernate以提供持久性。结构如下： - 管理 - >与豆和HTML / CSS的主程序 - Jar - >与罐子，Hibernate工具和类 - 战争 - >与Servlets

在它们之间，我使用Xstream来共享类和重要信息。

我使用Eclipse和Tomcat 7。

希望通过这一切都可以得到全球性的想法。

这是Xstream调试器所说的：

 原因：com.thoughtworks.xstream.converters.ConversionException：satdata.musicoterapia.hibernate.Terapeuta0：satdata.musicoterapia.hibernate.Terapeuta0 
 --- - 调试信息---- 
消息：satdata.musicoterapia.hibernate.Terapeuta0

 path：/ list / Usuario [2] / terapeuta 
 class [1]：java.util.ArrayList 
 converter-type [1]：com.thoughtworks.xstream.converters.collections.CollectionConverter

解决方案

在您的servlet代码中，您提到了：

  xstream.alias（Terapeuta，Terapeuta.class）; 
  

在XML文件中，它给出为：

 < terapeuta class =satdata.musicoterapia.hibernate.Terapeuta0resolves-to =Terapeuta> 
  

因此，在日志中您收到错误信息：

日志中的例外说：

com.thoughtworks.xstream.mapper.CannotResolveClassException：
satdata.musicoterapia.hibernate .Terativea0

好像你在MXL中的类名应该是 satdata.musicoterapia.hibernate.Terapeuta $ b $ pre $ satdata.musicoterapia.hibernate.Terapeuta0





[EDITED]

The project i'm working on is a 3 folder project in Java J2EE with servlets and Hibernate for the persistance. The structure is as follow: - Admin -> the main program with the beans and HTML/CSS - Jar -> with the jars, Hibernate tools and classes - War -> with the Servlets

Between them, I use Xstream to share the classes and important info.

I'm using Eclipse and Tomcat 7.

Hope that with this all of you get the global idea.

This what the Xstream debugger said:

解决方案

In your servlet code you are are mentioning :

xstream.alias("Terapeuta", Terapeuta.class);

In XML file it is given as:

<terapeuta class="satdata.musicoterapia.hibernate.Terapeuta0" resolves-to="Terapeuta">

So in logs you are getting error as:

The exception in logs says:

com.thoughtworks.xstream.mapper.CannotResolveClassException: satdata.musicoterapia.hibernate.Terapeuta0

it seems your class namein MXL should be satdata.musicoterapia.hibernate.Terapeuta

satdata.musicoterapia.hibernate.Terapeuta0
