之前遇到过rabbitmq队列卡死的问题,有消费者,但是就不消费队列里的消息;
后来发现是消费者执行webservice方法时,没有设置超时时间,默认永不超时,然后赶上对端系统出问题,方法就一直执行不完,队列消息也就一直卡住不动。(加try-catch是没有用的,catch不到,就是没有执行完一直卡住,因为超时时间默认永不超时)
在此总结下java webservice设置超时时间的方法。
try { JaxWsDynamicClientFactory dcf=JaxWsDynamicClientFactory.newInstance(); //这里有2种方法,不确定到底是哪种,就都写上了 dcf.getJaxbContextProperties().put("com.sun.xml.ws.request.timeout", 10000); dcf.getJaxbContextProperties().put("com.sun.xml.ws.connect.timeout", 10000); dcf.getJaxbContextProperties().put("com.sun.xml.internal.ws.connection.timeout", 10000);//建立连接的超时时间为10秒 dcf.getJaxbContextProperties().put("com.sun.xml.internal.ws.request.timeout", 10000);//指定请求的响应超时时间为10秒 LOGGER.info("设置超时时间"); Client client= dcf.createClient("http://128.0.0.1/A/services/BService?wsdl"); //这里再设置超时时间好像也行 //client.getRequestContext().put("com.sun.xml.ws.request.timeout", 10000); //client.getRequestContext().put("com.sun.xml.ws.connect.timeout", 10000); //client.getRequestContext().put("com.sun.xml.internal.ws.connection.timeout", 10000);//建立连接的超时时间为10秒 //client.getRequestContext().put("com.sun.xml.internal.ws.request.timeout", 10000);//指定请求的响应超时时间为10秒 //如果不设置超时时间,那么如果连接不通,就会卡在这一步 Object[] resultObj = client.invoke("createOrenableAccount", new Object[] { accountToXML("abc") }); String retXML = resultObj[0].toString(); StringReader read = new StringReader(retXML); InputSource source = new InputSource(read); SAXBuilder sb = new SAXBuilder(); Document doc = sb.build(source); Element root = doc.getRootElement(); LOGGER.info(root.getChildText("code"));// 0 成功 LOGGER.info(root.getChildText("code") + ", " + root.getChildText("message")); } catch (Exception e) { LOGGER.error((new StringBuilder("invokeWS Exception:")).append(e).toString(),e); } ------------------ public static String accountToXML(String userName) { Document document = null; Element et = new Element("account"); document = new Document(et); document = addNode(document, "appname", "AI"); document = addNode(document, "uid", userName); document = addNode(document, "eruid", userName); return documentStr(document); } ------------------- public static String documentStr(Document document) { XMLOutputter xop = new XMLOutputter(); String xmlStr = xop.outputString(document); return xmlStr; } ------------------------ pom.xml是这样: <!-- Apache CXF --> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-rs-client</artifactId> <version>3.0.0</version> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-frontend-jaxws</artifactId> <version>3.0.0</version> </dependency>
