Question

我正在使用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。我为所有请求设置了过滤器，以进行一些日志记录并向MDC添加一些值（例如requestId），但异常来自此处。这是堆栈：

奇怪的是，虽然请求已成功处理，并且成功响应（在此堆栈显示之前，有200发送回调用客户端。我很茫然。而且，堆栈中的行来自于我代码（com.xyz.gatorws.webapp.LoggingFilter.doFilter(LoggingFilter.java:34)）如下：

chain.doFilter(httpRequest, response);

这很奇怪，因为过滤器在处理请求之前运行。啊！我肯定错过了什么。我在LoggingFilter.destroy()方法中清除了日志记录上下文，所以看不到涉及另一个请求，但是我真的很茫然。

任何想法都将不胜感激。

如果这可以帮助提问者或其他人

我的配置是 Java9 Tomcat9 Jersey2。我遇到了这样的问题，因为匹配的方法没有用任何 HTTP 方法注释进行注释。在我的情况下，@GET 丢失了。该方法正在返回一个 Response 对象，并且在 return Response ... 之前的最后一条语句之后，它抛出了 NotFoundException。我认为 Jersey 认为这个方法是由于 @Path 注释而找到的子资源定位器。

所以我改变了这个：

@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();
}

为此：

@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();

}

但在我的情况下，由于异常，请求没有生成任何 200 响应代码，客户端得到 500，因为我有一个 RuntimeExceptionMapper。

请求后发生“ javax.ws.rs.NotFoundException：未找到HTTP 404”
