HTTP 400 on on使用Spring 4 MVC和MappingJackson2HttpMessageConverter定义的Restful post服务

Question

我尝试使用Spring 4 MVC创建一个安静的控制器，并通过点击下面提到的RestFul Post Web服务来测试它，但是在我将MappingJackson2HttpMessageConverter添加到我的后面时，将HTTP / 1.1 400 Bad Request作为响应调度员servlet.xml中。响应正确如果我使用＆＃39; @RequestBody字符串资源＆＃39;而不是＆＃39; @RequestBody资源资源＆＃39; for ResourceController post方法参数。我已经将MappingJackson2HttpMessageConverter添加到了dispatcher-servlet.xml，因为spring没有检测到jackson并且在点击这个帖子服务时抛出HTTP 415。

网址：http://localhost:8080/rma/api/resources/1
