xstream正在转换＆amp;(xstream is converting & to & when converting from xml to Java Objects)

 xstream正在转换& to & when从xml转换为Java Objects时。 我不希望这种情况发生。 我该怎么办？ 
 

 XStream xstream = new XStream(new DomDriver());

            xstream.processAnnotations(HelpConfigVO.class);
            xstream.processAnnotations(ProductVO.class);
            xstream.processAnnotations(PackageVO.class);
            xstream.addImplicitCollection(HelpConfigVO.class, "packages");
            configVO = (HelpConfigVO)xstream.fromXML(helpConfigData);

 

 其次，我从xstream获得的输出XML没有格式化。 如何格式化我的xml以使其可读？ 

xstream is converting & to & when converting from xml to Java Objects. I don't want this to happen. How shall I do it?
 

 XStream xstream = new XStream(new DomDriver());

            xstream.processAnnotations(HelpConfigVO.class);
            xstream.processAnnotations(ProductVO.class);
            xstream.processAnnotations(PackageVO.class);
            xstream.addImplicitCollection(HelpConfigVO.class, "packages");
            configVO = (HelpConfigVO)xstream.fromXML(helpConfigData);

 

Secondly, The output XML I am getting from xstream is not formatted. How do I format my xml to make it readable?

 如果你考虑可能分配给它的东西，一切都是有意义的。 
 

List<? super Number> list1 = new ArrayList<Object>(); // works
List<? super Number> list1 = new ArrayList<Number>(); // works
List<? super Number> list1 = new ArrayList<Integer>(); // doesn't work

 

 任何在右侧工作的东西都会接受Double 。 
 

List<? super Integer> list = new ArrayList<Object>(); // works
List<? super Integer> list = new ArrayList<Number>(); // works
List<? super Integer> list = new ArrayList<Integer>(); // works

 

 任何你可以分配给list1你也可以分配给list 。 所以list = list1工作得很好。 但并非所有可以分配给list的东西都会接受Double ，所以它不能编译。 

Everything makes sense if you consider the possible things you could assign to it.
 

List<? super Number> list1 = new ArrayList<Object>(); // works
List<? super Number> list1 = new ArrayList<Number>(); // works
List<? super Number> list1 = new ArrayList<Integer>(); // doesn't work

 

Anything that works on the right hand side will accept a Double.
 

List<? super Integer> list = new ArrayList<Object>(); // works
List<? super Integer> list = new ArrayList<Number>(); // works
List<? super Integer> list = new ArrayList<Integer>(); // works

 

Anything that you could assign to list1 you could also assign to list. So list = list1 works just fine. But not all of the things you could assign to list will accept a Double, so it doesn't compile.
