RETEasy @WrappedMap
我正在使用 RESTEasy 编写 RESTful Web 服务，并尝试编写包含 HashMap 的响应。 Web 服务生成 JSON 或 XML。 JSON 映射是正确的，但 XML 映射没有内容。 RESTEasy @WrappedMap 注释应该将 Map 编组为 XML。
@XmlRootElement(name="Response")
public class RootResponse {
private HashMap<String, String> test;
public RootResponse() {
test = new HashMap<String, String>();
test.put("Fred", "Wilma");
test.put("Barney", "Betty");
}
@XmlElement
@WrappedMap(map="test", key="name", entry="spouse")
public HashMap<String, String> getTest() {
return this.test;
}
}
JSON 输出：
{
"test": {
"Fred": "Wilma",
"Barney": "Betty"
}
}
XML 输出：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Response>
<test/>
</Response>
如果省略 @WrappedMap 注释，我会得到相同的输出。
@WrappedMap 不适用于属性吗？
I am using RESTEasy to write a RESTful web service and trying to write a response that contains a HashMap. The web service produces either JSON or XML. The JSON map is correct, but the XML map has no content. The RESTEasy @WrappedMap annotation is supposed to marshal Maps to XML.
@XmlRootElement(name="Response")
public class RootResponse {
private HashMap<String, String> test;
public RootResponse() {
test = new HashMap<String, String>();
test.put("Fred", "Wilma");
test.put("Barney", "Betty");
}
@XmlElement
@WrappedMap(map="test", key="name", entry="spouse")
public HashMap<String, String> getTest() {
return this.test;
}
}
JSON output:
{
"test": {
"Fred": "Wilma",
"Barney": "Betty"
}
}
XML output:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Response>
<test/>
</Response>
I get the same output if I leave out the @WrappedMap annotation.
Does @WrappedMap not work for properties?

我知道你发布这个问题已经有一段时间了，但我仍然想分享我最近学到的东西，以防其他人偶然发现这个问题。
@WrappedMap根据 本文档仅帮助更改输出 XML 中的元素名称。至于为什么你不能让JAXB从HashMap输出XML，我认为此页有说明。希望这有帮助。
I know it has been a while since you posted this question, but I still want to share what I have recently learnt in case someone else may stumble upon this question.
@WrappedMapaccording to this documentation only helps changing the name of the elements in the output XML. As to why you cannot get JAXB to output XML from theHashMap, I think this page has the explanation.Hope this helps.
