试试这个
filters((new Filter() {
@Override
public Response filter(FilterableRequestSpecification requestSpec, FilterableResponseSpecification responseSpec, FilterContext ctx) {
Response response = ctx.next(requestSpec, responseSpec);
String content=new String(response.getBody().asString());
Response Response2 = new ResponseBuilder().clone(response).setContentType(ContentType.JSON).setBody(content).build();
return Response2;
}
})
