问题描述
我在 **oss AS 6 中通过 RestEasy 使用 JAX-RS.当我的 JAX-RS 资源返回项目集合(例如通过列表)时,RESTEasy 总是使用名称 collection 作为根元素.
I'm using JAX-RS via RestEasy in **oss AS 6. When my JAX-RS resource returns a collection of items (e.g. via a List), RESTEasy always uses the name collection as the root element.
例如
<collection> <item> <description>computer</description> <price>2500</price> </item> <item> <description>tv</description> <price>1500</price> </item> </collection>
此 XML 由例如:
@Produces("application/xml") @Path("xml") @RequestScoped public class MyResource { @GET @Path("myitems") public List<Item> getMyItems() { return ... } }
可以看出,RESTEasy 创建的根标签始终是<collection>.
As can be seen the root tag that has been created by RESTEasy is always <collection>.
另一方面,Jersey 总是创建一个名称,该名称是列表中包含的元素的复数形式:
Jersey on the other hand always creates a name that is the plural form of the element contained in the list:
<items> <item> <description>computer</description> <price>2500</price> </item> <item> <description>tv</description> <price>1500</price> </item> </items>
我知道可以创建一个包装器类型并返回它而不是 List,但这是一个相当复杂的解决方法,并且使代码更加复杂.
I know it's possible to create a wrapper type and return that instead of a List, but that's a rather elaborate workaround and makes the code more complicated.
是否可以轻松地为集合指定根标签的名称?
Is it possible to easily specify what the name of the root tag is for collections?
推荐答案
貌似是RTFM的一个案例:RestEasy 文档 - JAXB 对象的数组和集合
Appeared to be a case of RTFM: RestEasy docs - Arrays and Collections of JAXB Objects
所以,如果我们想输出这个 XML
So, if we wanted to output this XML
<foo:list xmlns:foo="http://foo.org"> <customer><name>bill</name></customer> <customer><name>monica</name></customer> </foo:list>
我们会使用@Wrapped注解如下:
We would use the @Wrapped annotation as follows:
@GET @Path("list") @Produces("application/xml") @Wrapped(element="list", namespace="http://foo.org", prefix="foo") public List<Customer> getCustomerSet() { ... }
因此可以通过 @Wrapped 注释来实现.这是一个 RESTEasy 特定的,但现在就可以了.
It's thus possible via the @Wrapped annotation. It's a RESTEasy specific one, but this will do for now.
留下问题以防有人有更好的解决方案(仍在寻找一个全局拦截器 orso 让 RESTEasy 做 Jersey 做的事情).
Leaving the question open in case someone has an even better solution (still looking for a global interceptor orso that lets RESTEasy do what Jersey does).
