我不确定JSR 339:JAX-RS 2.0:用于RESTful Web Services的Java API是否已经涵盖了这一点。
为此,您可能需要扩展 Response.StatusType。
public abstract class AbstractStatusType implements StatusType {
public AbstractStatusType(final Family family, final int statusCode,
final String reasonPhrase) {
super();
this.family = family;
this.statusCode = statusCode;
this.reasonPhrase = reasonPhrase;
}
protected AbstractStatusType(final Status status,
final String reasonPhrase) {
this(status.getFamily(), status.getStatusCode(), reasonPhrase);
}
@Override
public Family getFamily() { return family; }
@Override
public String getReasonPhrase() { return reasonPhrase; }
@Override
public int getStatusCode() { return statusCode; }
public ResponseBuilder responseBuilder() { return Response.status(this); }
public Response build() { return responseBuilder().build(); }
public WebApplicationException except() {
return new WebApplicationException(build());
}
private final Family family;
private final int statusCode;
private final String reasonPhrase;
}
以下是一些扩展的 statust 类型。
public class BadRequest400 extends AbstractStatusType {
public BadRequest400(final String reasonPhrase) {
super(Status.BAD_REQUEST, reasonPhrase);
}
}
public class NotFound404 extends AbstractStatusType {
public NotFound404(final String reasonPhrase) {
super(Status.NOT_FOUND, reasonPhrase);
}
}
我就是这样做的。
@POST
public Response create(final MyEntity entity) {
throw new BadRequest400("bad ass").except();
}
@GET
public MyEntity read(@QueryParam("id") final long id) {
throw new NotFound404("ass ignorant").except();
}
// Disclaimer

// I don't know what 'bad ass' or 'ass ignorant' means.
