如何创建自动转换响应的JAXBElement到XML

问题描述：

@Controller 
@RequestMapping(value="/fake_cp") 
public class FakeContentProvider { 
    @RequestMapping(value="/request") 
    public @ResponseBody JAXBElement<MetaRequest> request(
      @Valid @ModelAttribute FaceContentProviderCommand command 
      ) 
      throws Exception { 
     ru.icb.cpaclick.controller.jaxb.MetaRequest request = new ru.icb.cpaclick.controller.jaxb.MetaRequest(); 
     request.setAccessUrl("http://accessUrl.ru"); 
     request.setErrorUrl("http://errorUrl.ru"); 
     request.setShortdesc("This is short desc"); 
     request.setLoadUrl("http://loadru.ru"); 
     request.setTariffclass(20501); 
     return new ObjectFactory().createRequest(request); 

}

如何进行的JAXBElement创建响应转换器，或者如何配置弹簧？

答

这可能不是在Spring中处理REST或SOAP服务的最佳方式。

弹簧mvc控制器最适合用于渲染网页。如果您想处理REST或SOAP服务，最好添加一个与Spring集成的Apache XCF servlet。

使用xjc（REST）和wsimport（SOAP），您可以使用合同优先方法来生成与您想要公开的服务相关的类和接口。根据您在xcf配置中创建端点并完成。
