java - 异常后继续列表迭代

Question

            List<String> assignedGroups = new ArrayList<>();
            assignedGroups.add("Group1");
            assignedGroups.add("Group2");
            assignedGroups.add("Group3");
            assignedGroups.add("Group4");
            assignedGroups.forEach(assignedGroup -> {

                System.out.println("");
                System.out.println("Retrieving tickets from " + assignedGroup + " ...");
                System.out.println("");

                /**
                 * @param args
                 * Cloud Server Deployment - Create server in CIA in Active state
                 */
                // Create SOAP Response
                String qualification = "'Priority' == \"Critical\" AND 'Assigned Group' = \""+ assignedGroup + "\"";
                SOAPMessage soapResponse = null;
                try {
                    soapResponse = soapConnection.call(createSOAPRequest(qualification), url);
                } catch (Exception e) {
                    e.printStackTrace();
                }
                try {
                    if (soapResponse != null) {
                        soapResponse.writeTo(System.out);
                        System.out.println("Giant Spaghetti Monster!");
                    }
                } catch (SOAPException | IOException e) {
                    e.printStackTrace();
                }

                // Print the SOAP Response
                try {
                    printSOAPResponse(soapResponse, soapConnection);
                } catch (Exception e) {
                    e.printStackTrace();
                }

            });

有时，我在尝试检索 SOAP 响应时会收到 NullPointerException:

<?xml version="1.0" encoding="utf-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><soapenv:Fault><faultcode>soapenv:Server.userException</faultcode><faultstring>ERROR (302): Entry does not exist in database; </faultstring><detail><ns1:hostname xmlns:ns1="http://xml.apache.org/axis/">WEBDKBA866</ns1:hostname></detail></soapenv:Fault></soapenv:Body></soapenv:Envelope>
java.lang.NullPointerException

现在，有没有办法忽略它并继续迭代列表中的下一组，而不是修复异常？

例如，NPE 发生在 Group3。我可以直接转到 Group4 来避免脚本崩溃吗？我已经在 NPE 发生的地方打印了 Giant Spaghetti Monster。这可能吗？

您正在捕获 SOAPException | IOException。也捕获异常..
