我想实现 Spring REST 方法。我尝试了 Get 并且它有效:

@RequestMapping(value = "{systemId}", method = RequestMethod.GET)
    public
    @ResponseBody
    Configuration getConfigurationInJSON(HttpServletResponse response, @PathVariable long systemId) throws IOException {
        if (configurationMap.containsKey(systemId)) {
            return configurationMap.get(systemId);
        } else {
            response.sendError(HttpServletResponse.SC_NOT_FOUND);
            return null;
        }
    }

但是,当我想实现 DELETE 时,它不会。我的方法是:

@RequestMapping(value = "{systemId}", method = RequestMethod.DELETE)
    public void deleteConfiguration(HttpServletResponse response, @PathVariable long systemId) throws IOException {
        if (configurationMap.containsKey(systemId)) {
            configurationMap.remove(systemId);
            response.setStatus(HttpServletResponse.SC_FOUND);
        } else {
            response.sendError(HttpServletResponse.SC_NOT_FOUND);
        }

    }

我的 web.xml 如下:

mvc-dispatcher org.springframework.web.servlet.DispatcherServlet 1

<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/ui/*</url-pattern>
</servlet-mapping>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

当我尝试使用 Curl for GET 时有效的命令:

curl http://localhost:8080/ui/webapp/conf/1

当我尝试使用 Curl 进行 DELETE 时,该命令不起作用:

curl -x delete http://localhost:8080/ui/webapp/conf/1

第二个命令在 curl 一段时间后给出了该错误:

curl: (7) couldn't connect to host

Tomcat端没有错误,调试时也没有进入delete方法体。

有任何想法吗?

尝试

curl -X DELETE http://localhost:8080/ui/webapp/conf/1

带大写DELETE和大写X
