我正在尝试为处理COPY HTTP方法的资源创建自定义Spring MVC Controller.
@RequestMapping仅接受以下RequestMethod值:GET,HEAD,POST,PUT,PATCH,DELETE,OPTIONS和TRACE.
在Spring MVC Controller中是否有任何推荐的处理自定义HTTP方法的方法?
该Servlet规范只允许GET,HEAD,POST,PUT,DELETE,OPTIONS或TRACEHTTP方法。这可以在 Servlet API的 Apache Tomcat实现中看到。
这反映在 Spring API 的RequestMethod枚举中。
您可以通过实现自己的DispatcherServlet覆盖service方法以允许COPYHTTP 方法来绕过这些方法 - 将其更改为 POST 方法,并自定义RequestMappingHandlerAdapterbean 以允许它。
像这样,使用 spring-boot:
@Controller
@EnableAutoConfiguration
@Configuration
public class HttpMethods extends WebMvcConfigurationSupport {
public static class CopyMethodDispatcher extends DispatcherServlet {
private static final long serialVersionUID = 1L;
@Override
protected void service(final HttpServletRequest request, final HttpServletResponse response) throws ServletException, IOException {
if ("COPY".equals(request.getMethod())) {
super.doPost(request, response);
}
else {
super.service(request, response);
}
}
}
public static void main(final String[] args) throws Exception {
SpringApplication.run(HttpMethods.class, args);
}
@RequestMapping("/method")
@ResponseBody
public String customMethod(final HttpServletRequest request) {
return request.getMethod();
}
@Override
@Bean
public RequestMappingHandlerAdapter requestMappingHandlerAdapter() {
final RequestMappingHandlerAdapter requestMappingHandlerAdapter = super.requestMappingHandlerAdapter();
requestMappingHandlerAdapter.setSupportedMethods("COPY", "POST", "GET"); // add all methods your controllers need to support
return requestMappingHandlerAdapter;
}
@Bean
DispatcherServlet dispatcherServlet() {
return new CopyMethodDispatcher();
}
}

现在您可以/method使用COPYHTTP 方法调用端点。使用curl这将是:
curl -v -X COPY http://localhost:8080/method
