请求后出现"javax.ws.rs.NotFoundException: HTTP 404 Not Found“
请求后出现"javax.ws.rs.NotFoundException: HTTP 404 Not Found“
提问于 2020-06-17 00:18:57
我正在开发一个Java8 Tomcat8 Jersey2 web应用程序，它在成功响应请求后随机记录了一个奇怪的异常。我为所有的请求准备了一个过滤器，以便做一些日志记录，并向MDC添加一些值(例如requestId)，异常来自这里。下面是堆栈：

at java.lang.Thread.run(Thread.java:748)奇怪的是，请求被成功地处理了，并且在这个堆栈出现之前，一个成功的响应(200 )被发送回调用客户机。我不知所措。此外，堆栈中来自我的代码(com.xyz.gatorws.webapp.LoggingFilter.doFilter(LoggingFilter.java:34))的行如下所示：
chain.doFilter(httpRequest, response);这很奇怪，因为过滤器是在处理请求之前运行的。啊！我一定漏掉了什么。我清除了LoggingFilter.destroy()方法中的日志记录上下文，这样就看不到涉及到另一个请求，但我真的很困惑。
任何想法都将不胜感激。

以防这对提问者或其他人有帮助
我的配置是Java9 Tomcat9 Jersey2。我遇到了一个类似的问题，就是匹配的方法没有使用任何HTTP方法注释。在我的例子中，@GET丢失了。该方法返回一个Response对象，并且在return Response ...之前的最后一条语句之后抛出NotFoundException。我认为Jersey认为这个方法是一个子资源定位器，它是由于@Path注释而找到的。
所以我改变了这一点：
@Path("unique/page")
@Consumes("*/*")
@RolesAllowed("owner")
public Response getUnique(@PathParam("userUUID") String userUUID) throws RuntimeException {
LogNdc.log("userUUID: " + userUUID);
SearchCompanieService scs = new SearchCompanieService();
CompanyPagePojo cpp = scs.searchByFieldNameAutoCommit("userPojoOwnerId", userUUID);
System.out.println(cpp);
return Response.status(Status.OK).entity(cpp).build();
}要这样做：
@Path("unique/page")
@GET
@Consumes("*/*")
@RolesAllowed("owner")
public Response getUnique(@PathParam("userUUID") String userUUID) throws RuntimeException {
LogNdc.log("userUUID: " + userUUID);
SearchCompanieService scs = new SearchCompanieService();
CompanyPagePojo cpp = scs.searchByFieldNameAutoCommit("userPojoOwnerId", userUUID);
System.out.println(cpp);
return Response.status(Status.OK).entity(cpp).build();}
但在我的例子中，由于异常，请求没有生成任何200响应代码，因为我有一个RuntimeExceptionMapper，所以客户端得到了500个响应代码。
