这是Spring MVC @PathVariable被截断的问题的延续

Spring论坛声明它已修复(3.2版本)作为ContentNegotiationManager的一部分.见下面的链接.
https://jira.springsource.org/browse/SPR-6164
https://jira.springsource.org/browse/SPR-7632

在我的应用程序中,带有.com的requestParameter被截断.

谁能解释我如何使用这个新功能？它是如何在xml中配置的？

注意:spring论坛 - #1带有点(.)的Spring MVC @PathVariable正在被截断

在PHP中创建平面文件数据库结构的最佳实践是什么？

我看到很多比较成熟的PHP平面文件框架试图实现类似SQL的查询语法,这在大多数情况下都是我的目的(我只会在那时使用数据库).

是否有任何优雅的技巧,以获得良好的性能和功能与小代码开销？

我正在尝试生成一个简单的JSON响应.现在我得到406 Not Acceptable错误.Tomcat说:"此请求标识的资源只能根据请求"接受"标题生成具有不可接受特征的响应." 即使我的Accept标题是

Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

在tomcat/lib中,我有所有Tomcat jar,Spring jar和jackson-all-1.9.0.jar.我正在使用Spring 3.2.2和Tomcat 7.

我知道这个问题已经讨论了很多次,但没有一个解决方案适合我.

使用spring,使用以下代码:

List<HttpMessageConverter<?>> messageConverters = restTemplate.getMessageConverters();
for(HttpMessageConverter httpMessageConverter : messageConverters){
  System.out.println(httpMessageConverter);
}
ResponseEntity<ProductList> productList = restTemplate.getForEntity(productDataUrl,ProductList.class);

我正在使用springMVC,并且在尝试进行更新时遇到异常.

我尝试在发送 GET 请求时返回 JSONObject。

方法

  @RequestMapping(value = "/{businessId}/{orderId}/{reportId}", method = RequestMethod.GET,
    produces = MediaType.APPLICATION_JSON_VALUE)
  @ResponseBody
  public ResponseEntity<JSONObject> getReport(@PathVariable("businessId") String businessId,
                                               @PathVariable("orderId") String orderId,
                                               @PathVariable("reportId") Long reportId) throws JSONException {
    return new ResponseEntity<JSONObject>(reportService.getReportJSON(), HttpStatus.OK);
  }

我从文件中获取 json。这是一个单一的 json 对象。在一行。我像这样将它解析为 JSONObject

  fs = FileSystem.get(uri, conf);
  BufferedReader reader = null;
  reader = new BufferedReader(new InputStreamReader(fs.open(path)));
  line = reader.readLine();
  while (line != null) {
    jsonObjectList = new JSONObject(line);
    line = reader.readLine();
  }
  return jsonObjectList;

这就是我的文件的样子。

{"reportId":"1","description":"????????????????????????","orderId":"357","businessId":"??????????1","tables":[{"name":"???????","fields":[{"name":"0-17","type":"number"},{"name":"18-24","type":"number"},{"name":"25-34","type":"number"},{"name":"35-44","type":"number"},{"name":"45-54","type":"number"},{"name":"45-54","type":"number"},{"name":"45-54","type":"number"}],"data":[2571,5287,4587,7705,3675,3743,7423]},{"name":"???????","fields":[{"name":"0-17","type":"number"},{"name":"18-24","type":"number"},{"name":"25-34","type":"number"},{"name":"35-44","type":"number"},{"name":"45-54","type":"number"},{"name":"45-54","type":"number"},{"name":"45-54","type":"number"}],"data":[7552,3107,6477,4967,9106,7859,9060]},{"name":"???????????????","fields":[{"name":"0-17","type":"number"},{"name":"18-24","type":"number"},{"name":"25-34","type":"number"},{"name":"35-44","type":"number"},{"name":"45-54","type":"number"},{"name":"45-54","type":"number"},{"name":"45-54","type":"number"}],"data":[7552,3107,6477,4967,9106,7859,9060]}]}

所以我很难在json中编写我的bean ...首先我尝试使用codehaus'jackson 1.9.13和Spring MVC 3.1.1.我遇到了一些问题,直到我设法达到"直接自我引用"异常.看着这个我发现我需要更快的xml的杰克逊2.然后我发现(这里)我需要Spring 3.1.2因为之前的版本不支持Jackson 2.

所以,毕竟这......我仍然得到同样的例外.我的maven依赖确实包括Spring MVC 3.1.2发行版以及Jackson的2个jar(它们都在我的构建路径中)

这是我的控制器方法试图发送一个bean:

@RequestMapping(value = "/WS/{id}")
public @ResponseBody Resource displayWS(@PathVariable final int id) {
    return this.service.findById(id);
}

这是我在通话后在浏览器中收到的内容:

HTTP Status 406
The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers ().
