Spring Interceptor

Question

我需要创建一个拦截器来拦截HTTP请求和响应，但是在我看来我做错了什么，有人可以告诉我我应该更改或添加的内容吗？

public class HttpInterceptor extends HandlerInterceptorAdapter implements ClientHttpRequestInterceptor
{
    @Override
    public ClientHttpResponse intercept(final HttpRequest httpRequest, final byte[] bytes, final ClientHttpRequestExecution clientHttpRequestExecution) throws IOException
    {

        RestTemplate restTemplate = new RestTemplate();
        final ClientHttpResponse response = clientHttpRequestExecution.execute(httpRequest, bytes);
        final String httpResponseName = response.toString();

        final HttpHeaders httpHeaders = response.getHeaders();
        final HttpStatus httpStatusCode = response.getStatusCode();
        final String statusText = response.getStatusText();

        final String body = httpHeaders.toString() + httpStatusCode.toString() + statusText;
        //And then i will put body to DB

        return response;
    }

xml

<bean id="httpInterceptor" class="HttpInterceptor"/>
<bean id="httpInterceptor" class="de.hybris.platform.servicelayer.interceptor.impl.InterceptorMapping">
    <property name="interceptor" ref="httpInterceptor"/>
    <property name="typeCode" value="Message"/>
</bean>

我了解您尝试创建服务（可以是休息，肥皂或其他任何东西）。如果我是对的，则需要创建用于处理http请求的控制器。

@Controller("MyController")
public class MyController extends AbstractController {
    @RequestMapping(value = "/mymethod/{id}", method = RequestMethod.GET)
    public void myMethod(@PathVariable final String id, final HttpServletRequest request, final HttpServletResponse out) throws Exception {
    try {
        if (StringUtils.isEmpty(id))
            throw new UnknownIdentifierException("id is null!");
        out.setContentType(MediaType.APPLICATION_TXT_VALUE);
        IOUtils.copy(myStream, out.getOutputStream());
    } catch (UnknownIdentifierException ex) {
        out.setStatus(HttpServletResponse.SC_BAD_REQUEST);
        out.setContentType(MediaType.TEXT_PLAIN_VALUE);
        String message = "My error text!";
        IOUtils.copy(new ByteArrayInputStream(message.getBytes()), out.getOutputStream());
    } 
}
