我目前正在使用新的Camel REST DSL作爲基礎來開發基於REST的Java應用程序。 它主要的工作只是我通過一個REST客戶端調用URL時發現（而不是說一個瀏覽器）的JSON的反應是「亂碼」，並與我承擔什麼是錯誤的編碼駱駝休息DSL響應編碼
MyRouteBuilder來通過的.java
@Component
public class MyRouteBuilder extends RouteBuilder{
@Autowired
LocalEnvironmentBean environmentBean;
@Override
public void configure() throws Exception {
restConfiguration().component("jetty").host("0.0.0.0").port(80)
.bindingMode(RestBindingMode.auto);
rest("/testApp")
.get("/data").route()
.to("bean:daoService?method=getData")
.setProperty("viewClass", constant(CustomeJsonViews.class))
.marshal("customDataFormat").endRest()
.get("/allData").route()
.to("bean:daoService?method=getDatas")
.setProperty("viewClass", constant(CustomeJsonViews.class))
.marshal("customDataFormat").endRest();
}
}
CustomeDataFormat.java
public class CustomDataFormat implements DataFormat{
private ObjectMapper jacksonMapper;
public CustomDataFormat(){
jacksonMapper = new ObjectMapper();
}
@Override
public void marshal(Exchange exchange, Object obj, OutputStream stream) throws Exception {
Class view = (Class) exchange.getProperty("viewClass");
if (view != null)
{
ObjectWriter w = jacksonMapper.writerWithView(view);
w.writeValue(stream, obj);
}
else
stream.write(jacksonMapper.writeValueAsBytes(obj));
}
@Override
public Object unmarshal(Exchange exchange, InputStream stream) throws Exception {
return null;
}
}

當去到URL，{主機}在Chrome/testApp /數據，例如響應來自通過爲：
{
data: "Sherlock",
value: "Holmes",
count: 10
}
但是使用郵差瀏覽器插件的客戶端返回：

該問題似乎與REST綁定模式是「自動」並使用自定義編組器。 如果我將綁定模式設置爲「json」，那麼瀏覽器和客戶端響應都會出現亂碼。 如果我將綁定模式設置爲「json」並繞過自定義編組器，則一切正常。 有沒有辦法將路由配置爲使用自定義編組器並正確編碼響應而不考慮客戶端？
