spring - Spring MVC带注释的 Controller 方法，无法“查找”DELETE操作的方法

这是实际代码：

@RequestMapping(value = "/competitors/{id}", method = RequestMethod.GET)
public Competitor getCompetitor(@PathVariable("id") long id)
{
    Competitor competitor = competitorService.getCompetitorById(id);

    if (null == competitor)
    {
        EmptyResultDataAccessException e = new EmptyResultDataAccessException(1);
        logger.log(Level.WARN, e.getMessage());
        throw e;
    }

    return competitor;
}

@RequestMapping(value = "/competitors/{id}", method = RequestMethod.DELETE)
public String deleteCompetitor(@PathVariable("id") long id)
{
    Competitor competitor = new Competitor();
    competitor.setId(id);
    competitorService.deleteCompetitor(competitor);

    return "Solid gone!";
}

向/competitors/200发送删除请求会导致错误：
“HTTP状态405-不支持请求方法”“delete”“”
Spring的日志确认没有找到此方法的路径：

我的回答是“不”？.

最佳答案

我也有同样的问题。有什么帮助，可能不是最终的解决方案，但对我有效：
删除竞争对手方法的注释和参数的更改。移除ID（方法参数也是）。从httpservletrequest读取id参数。

@RequestMapping(value = "/competitors", method = RequestMethod.DELETE)
public String deleteCompetitor(HttpServletRequest request)
{
    String idHeader = request.getHeader("id");

    Integer id = Integer.valueOf(idHeader).intValue();

    Competitor competitor = new Competitor();
    competitor.setId(id);
    competitorService.deleteCompetitor(competitor);

    return "Solid gone!";
}

id参数以这种方式通过头传递（客户端代码-未完成）：

DefaultHttpClient httpClient = new DefaultHttpClient();

HttpDelete httpDelete = new HttpDelete...

...

httpDelete.setHeader("id", "123");

...

httpClient.execute(httpDelete);

我正在使用ApacheHTTPClient。
