球衣/默认默认字符编码 [英] Jersey / Rest default character encoding
问题描述
Jersey似乎在返回JSON时失败...
这个:
Jersey seems to fail when returning JSON...
This:
@GET
@Produces( MediaType.APPLICATION_JSON + ";charset=UTF-8")
public List<MyObject> getMyObjects() {
return ....;
}
需要
返回JSON utf-8编码.如果我只使用
is needed to return JSON utf-8 encoded. If I use only
@Produces( MediaType.APPLICATION_JSON)
失败,例如德国umlaute(üöä),将以错误的方式退还.
fails and for example German umlaute (üöä), will be returned in a wrong way.
两个问题:
1-对于JSON utf-8 ist标准-为什么不使用Jersey?
2-如果传入JSON请求,是否可以为整个REST-Servlet设置utf-8?
我正在Android上使用Jersey 1.5和CRest 1.0.1 ...
Two questions:
1 - For JSON utf-8 ist standard - why not with Jersey?
2 - Can I set utf-8 for the whole REST-Servlet if a JSON Request comes in?
I am using Jersey 1.5 and CRest 1.0.1 on Android...
推荐答案
SRG的建议就像一个魅力.但是,由于Jersey 2.0的界面略有不同,因此我们不得不对过滤器进行一些调整:
SRGs suggestion works like a charm. However, since Jersey 2.0 the interfaces are slightly different, so we had to adapt the filter a little bit:
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerResponseContext;
import javax.ws.rs.container.ContainerResponseFilter;
import javax.ws.rs.core.MediaType;
public class CharsetResponseFilter implements ContainerResponseFilter {
@Override
public void filter(ContainerRequestContext request, ContainerResponseContext response) {
MediaType type = response.getMediaType();
if (type != null) {
String contentType = type.toString();
if (!contentType.contains("charset")) {
contentType = contentType + ";charset=utf-8";
response.getHeaders().putSingle("Content-Type", contentType);
}
}
}
}
