如何创建 spring 控制器以将响应 jaxbelement 自动转换为 xml

Question

我有 spring 控制器：

@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);

}

服务器返回答案：

如何为 jaxbelement 创建响应转换器，或者如何配置 spring？

Answer 1

这可能不是在 Spring 中处理 REST 或 SOAP 服务的最佳方式。

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

使用 xjc (REST) 和 wsimport (SOAP)，您可以使用契约优先方法来生成与您要公开的服务相关的类和接口。
在此基础上，您在 xcf 配置中创建一个端点，然后就完成了。
