resteasy - 如何追踪 RESTEasy 的调度？

Question

我们在这里运行 RESTEasy 2.3.0.GA，我正在努力解决https://stackoverflow.com/questions/18219237/jax-rs-path-regex-fails-for-just-one-of-an- or-expression，我不知道如何让 RESTEasy 坦白为什么它认为特定的 URI 没有映射到我的处理程序。是否有一些调试级别可以让 RESTEasy 显示它的调度？

Answer 1

文档对您将获得的内容含糊不清，但他们使用的是 log4j、logback 和 java.util.logging 的 Logger。就我而言，将以下内容添加到 logback.xml 会给我一些稀疏信息。

<logger name="org.jboss.resteasy.core" level="debug" />
<logger name="org.jboss.resteasy.specimpl" level="debug" />
<logger name="org.jboss.resteasy.plugins.server" level="debug" />

这对我有用：

@Provider
@ServerInterceptor
public class LoggingInterceptor implements ContainerRequestFilter {

    private static final ObjectMapper MAPPER = new ObjectMapper();

    @Override
    public void filter(ContainerRequestContext containerRequestContext) throws IOException {
        if (REQUESTS_LOGGER.isDebugEnabled()) {
            final String method = containerRequestContext.getMethod();
            final String url = containerRequestContext.getUriInfo().getRequestUri().toString();
            final StringBuilder headersStr = new StringBuilder();
            MultivaluedMap<String, String> headers = containerRequestContext.getHeaders();
            for (MultivaluedMap.Entry<String, List<String>> header : headers.entrySet()) {
                headersStr.append(header.getKey()).append(": ").append(header.getValue()).append('\n');
            }
            String json = null;
            if ("POST".equals(method) || "PUT".equals(method)) {
                ByteArrayOutputStream baos = new ByteArrayOutputStream();
                IOUtils.copy(containerRequestContext.getEntityStream(), baos);
                byte[] jsonBytes = baos.toByteArray();
                json = new String(jsonBytes, "UTF-8");
                Object jsonObject = MAPPER.readValue(json, Object.class);
                json = MAPPER.writeValueAsString(jsonObject);
                containerRequestContext.setEntityStream(new ByteArrayInputStream(jsonBytes));
            }
            REQUESTS_LOGGER.restCall(method, url, headersStr.toString(), json == null ? "empty" : json);
        }
    }
}
