没有实际组成一个编写器并将每个元素附加到字符串上。有没有一种方法可以让JAXB编组器编组对象列表,而我可以在上面给出顶层元素的名称?
我觉得我已经很接近了
//http://blog.bdoughan.com/2012/07/jaxb-no-annotations-required.html
public <T> String jaxb(Collection<T> o, Class<T> clazz, String plural){
try {
ArrayList<T> al = new ArrayList<T>(o.size());
al.addAll(o);
JAXBContext jc = JAXBContext.newInstance(ArrayList.class);
JAXBElement<ArrayList> amenity = new JAXBElement(new QName(plural), ArrayList.class, al);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
StringWriter writer = new StringWriter();
marshaller.marshal(amenity, writer);
return writer.toString();
} catch (JAXBException e) {
throw new RuntimeException(e);
}
}

但结果仍然是一个空列表
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<pluralName/>

有没有一种方法,而不仅仅是手动将xml字符串粘贴在一起?
从迈克尔Glavassevich [我已一些帮助能有一点需要注意做到这一点,各个元素是<Item>小号
