就像标题所说的那样.
@WebService(
targetNamespace = "http://com.lalaland.TestWs",portName = "TestWs",serviceName = "TestWs")
public class TestWs implements TestWsInterface {
@EJB(name="validator")
private ValidatorLocal validator;
@WebMethod(operationName = "getStuff")
public List<StuffItem> getStuff(@WebParam(name = "aaa")String aaa,@WebParam(name = "bbb")int bbb ) {
if ( ! validator.check1(...) )
return HTTP code 403 <------------ Here
if ( ! validator.check2(...) )
return HTTP code 404 <------------ Here
if ( ! validator.check3(...) )
return HTTP code 499 <------------ Here
return good list of Stuff Items
}
无论如何我可以让方法按需返回特定的HTTP代码吗？我知道一些东西,如身份验证,内部服务器错误等,使得WS方法返回500和auth错误,但我希望能够按照业务逻辑发送这些错误.
有人这样做过吗？使用jax-WS已经有一段时间了,这是我第一次有这种需求,尝试搜索它并且无法在任何地方找到答案.
谢谢
解决方法
只获取javax.servlet.http.HttpServletResponse的当前实例并发送错误.
@WebService
public class Test {
private static final Logger LOG = Logger.getLogger(Test.class.getName());
@Resource
private WebServiceContext context;
@WebMethod(operationName = "testCode")
public String testCode(@WebParam(name = "code") int code) {
if (code < 200 || code > 299) {
try {
MessageContext ctx = context.getMessageContext();
HttpServletResponse response = (HttpServletResponse)
ctx.get(MessageContext.SERVLET_RESPONSE);
response.sendError(code,code + " You want it!");
} catch (IOException e) {
LOG.severe("Never happens,or yes?");
}
}
return code + " Everything is fine!";
}
}
