spring-mvc与jetty服务器上的resteasy字符编码问题

发布于 2024-11-03 05:34:39 字数 985 浏览 3 评论 0原文

我正在尝试在jetty服务器上实现restful协议。我有可运行的服务器，我可以从我的其余客户端访问它。我的服务器端项目是一个maven项目。我有一个关于字符编码的问题。当我在从控制器发送它之前检查响应时，不存在编码问题。但是在我向客户端返回响应后，我看到了损坏的数据。响应头是 UTF-8。另外，我有一个针对此问题的侦听器，并且我设置为请求和响应 UTF-8。我想当我尝试将响应数据写入响应时会发生问题。

@GET
@Path("/")
@Produces({"application/xml;charset=UTF-8","application/json;charset=UTF-8"})
public String getPersons(@Context HttpServletRequest request, @Context HttpServletResponse response) {

    List<Person> persons = personService.getPersons(testUserId, collectionOption, null);
    if (persons == null) {
        persons = new ArrayList<Person>();
    }

    String result = JsonUtil.listToJson(persons);
    //result doesnt has any encoding problem at this line

    response.setContentType("application/json");
    response.setContentLength(result.length());
    response.setCharacterEncoding("utf-8");

    //i guess problem happen after this line
    return result;
}

有没有jetty配置或者resteasy配置？或者有什么办法可以解决这个问题吗？感谢您的帮助。

I am trying to implement restful protocol on jetty server. I have runnable server and i can access it from my rest client. My server side project is a maven project. I have a problem about the character encoding.When i check response, before send it from controller, there is no encoding problem. But after i return response to client, i see broken data. Response header is UTF-8. Also i have a listener for this problem and i am setting to request and response to UTF-8. I guess problem happens when i try to write my response data to response.

@GET
@Path("/")
@Produces({"application/xml;charset=UTF-8","application/json;charset=UTF-8"})
public String getPersons(@Context HttpServletRequest request, @Context HttpServletResponse response) {

    List<Person> persons = personService.getPersons(testUserId, collectionOption, null);
    if (persons == null) {
        persons = new ArrayList<Person>();
    }

    String result = JsonUtil.listToJson(persons);
    //result doesnt has any encoding problem at this line

    response.setContentType("application/json");
    response.setContentLength(result.length());
    response.setCharacterEncoding("utf-8");

    //i guess problem happen after this line
    return result;
}

Is there any jetty configuration or resteasy configuration for it? Or is there any way to solve this problem? Thanks for your helps.

您使用的是哪个 Resteasy 版本？ 2.0.1 及之前版本中的字符串存在一个已知问题 (RESTEASY-467)。

这些是你的选择：

1）强制编码返回 byte[]

public byte[] getPersons

，然后

return result.getBytes("UTF8");

2）返回 List（或者如果需要的话创建一个 PersonListing）

public List<Person> getPersons

并让 Resteasy 处理 json 转换。

3) 返回 StreamingOutput

注意：使用此选项，“Content-Length”标头将是未知的。

return new StreamingOutput()
{

    public void write(OutputStream outputStream) throws IOException, WebApplicationException
    {
        PrintStream writer = new PrintStream(outputStream, true, "UTF-8");
        writer.println(result);
    }
};

4) 升级到2.2-beta-1或更高版本。

Which resteasy version are you using? There is a known issue (RESTEASY-467) with Strings in 2.0.1 an prior.

These are your options:

1) force the encoding returning byte[]

public byte[] getPersons

and then

return result.getBytes("UTF8");

2) return List (or create a PersonListing if you need it)

public List<Person> getPersons

and let resteasy handle the json transformation.

3) return a StreamingOutput

NOTE: with this option the "Content-Length" header will be unknown.

return new StreamingOutput()
{

    public void write(OutputStream outputStream) throws IOException, WebApplicationException
    {
        PrintStream writer = new PrintStream(outputStream, true, "UTF-8");
        writer.println(result);
    }
};

4) upgrade to 2.2-beta-1 or newer version.
