Jersey MessageBodyWriter not found for media type=text/plain
提问by Little Code
I'm trying to follow the Jersey docs to enable a non-200 response if an error occured (https://jersey.java.net/documentation/latest/representations.html#d0e3586)
如果发生错误，我正在尝试按照 Jersey 文档启用非 200 响应（https://jersey.java.net/documentation/latest/representations.html#d0e3586）
My code looks like :
我的代码看起来像：
@POST
@Produces(MediaType.TEXT_PLAIN)
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public ResponseBuilder getData(@FormParam("one") String one,@FormParam("two") String two,@FormParam("three") String three) {
if(one.isEmpty() || two.isEmpty() || three.isEmpty()) {
logger.error("Missing params for getData");
throw new WebApplicationException(501);
}
return Response.ok();
}
}
This unfortunately yields the following error :
不幸的是，这会产生以下错误：

The problem is the return type of your method. It has to be Responseinstead of ResponseBuilder.
问题在于您的方法的返回类型。它必须是Response而不是ResponseBuilder.
Change your code to the following and it should work:
将您的代码更改为以下内容，它应该可以工作：
@POST
@Produces(MediaType.TEXT_PLAIN)
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public Response getData(@FormParam("one") String one,@FormParam("two") String two,@FormParam("three") String three) {
if(one.isEmpty() || two.isEmpty() || three.isEmpty()) {
logger.error("Missing params for getData");
throw new WebApplicationException(501);
}
return Response.ok();
}
