Question

我一直在努力（现在大约一天）弄清楚如何从我的客户端向我的网络服务发送@POST请求，但我收到403错误，我不明白为什么。我已经尝试编辑我的web.xml文件以允许正确的授权，但它仍然无法正常工作。下面是我的WEB-INF web.xml和Tomcat web.xml文件。任何帮助将不胜感激，这已经超出了令人沮丧的程度。另外，我对Tomcat和Jersey都很新，所以它很可能是一个非常愚蠢/简单的错误。

功能

OS X El Capitan 10.11.2
Tomcat版本7.0服务器
Eclipse JEE Kepler R Cocoa x86_64
Jersey 2.23.1
JRE 1.7

Answer 1

这不应该发生。您的错误在某处处理。看看这些注释：

@ControllerAdvice
@ResponseStatus(HttpStatus.FORBIDDEN)
@ExceptionHandler(YourException.class)

Answer 2

此示例（https://wolfpaulus.com/journal/java-journal/jersey/）有一些改动的web.xml：

<display-name>Jersey Web Application</display-name>
<servlet>
    <servlet-name>javax.ws.rs.core.Application</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

该示例页面似乎突出了您的确切环境（除了作者使用IntelliJ而不是Eclipse ...但您可以免费下载社区版，而Java 8而不是7） - 所以您可能想要跟随它起床并运行。
