我有一个JAXB对象,我可以解组很好.但是,如果我添加一个使用@XmlAnyElement注释的Element []字段,则在尝试解组时会抛出：
java.lang.IllegalStateException: You are running with invalid JAXP api or implementation. JAXP api/implementation of version 1.3.1 (included in JDK6) or higher is required. In case you are using ant,make sure ant 1.7.0 or higher is used – older versions of ant contain JAXP api/impl version 1.2 (in xml-apis.jar). If you want to keep using older ant versions,you have to configure it to use higher the JAXP api/impl versions.
这是通过我通过Eclipse插件运行的TestNG测试运行的.我正在运行1.6 JDK并配置maven以排除旧版本的xml-apis jar但是我似乎无法让它工作.我假设我仍然从某个地方拾取不兼容的库版本,但不知道从哪里来.
直接通过Eclipse运行我得到：

解决方法
看起来这个问题是由旧版本的Xalan造成的.从JDK 5开始,似乎需要最低版本2.7.0.另一个库提供了旧版本,因此我将其从Maven构建中排除,现在一切看起来都很好.
