我有一个JAR,它对数据库所有源系统中的所有表执行一些验证。在所有源系统中,表每四小时加载一次。有时,我希望对特定源系统的表进行验证,而不是对所有源运行JAR,因此我希望添加在运行JAR时从参数发送源系统名称的选项。到目前为止,这就是我提出的代码:
public static void main(String[] args) throws SQLException, IOException, AddressException, InterruptedException {
GpHiveRecords brge;
Options options = new Options();
Option input = new Option("s", "ssn", true, "source system names");
input.setRequired(true);
options.addOption(input);
CommandLineParser parser = new DefaultParser();
HelpFormatter formatter = new HelpFormatter();
CommandLine cmd = null;
try {
cmd = parser.parse(options, args);
if (cmd.hasOption("s")) {
String sources = cmd.getOptionValue("s");
if (sources == null) {
System.out.println("Please enter the source system names to perform the Recon..");
} else {
brge = new GpHiveRecords(sources);
brge.createReconFile();
}
} else {
brge = new GpHiveRecords();
brge.createReconFile();
}
} catch (ParseException e) {
formatter.printHelp("utility-name", options);
e.printStackTrace();
System.exit(1);
return;
} catch (Exception e) {
e.printStackTrace();
}
如果在命令中使用所需的参数,则应该是:
java -Xdebug -Dsun.security.abc2.debug=true -Djava.security.abc2.conf=/etc/abc2.conf -Djava.security.abc2.realm=PRODEV.COM -Djava.security.abc2.kdc=ip-00-000-000-000.ab3.internal -Djavax.security.auth.useSubjectCredsOnly=false -jar /home/supusr/AutoVal/AutoVal_Dev.jar --s oracle, sap
由于我没有在其他类中编写逻辑来验证从cli发送的源代码,所以在提交jar时,我已经在上面的代码中处理了绕过这个条件,在“if-else条件”中处理了是否没有“--s或--ssn”。
if (cmd.hasOption("s")) {
String sources = cmd.getOptionValue("s");
if (sources == null) {
System.out.println("Please enter the source system names to perform the Recon..");
} else {
brge = new GpHiveRecords(sources);
brge.createReconFile();
}
} else {
brge = new GpHiveRecords();
brge.createReconFile();
}
}
但当我提交jar时,如下所示:
java -Xdebug -Dsun.security.abc2.debug=true -Djava.security.abc2.conf=/etc/abc2.conf -Djava.security.abc2.realm=PRODEV.COM -Djava.security.abc2.kdc=ip-00-000-000-000.ab3.internal -Djavax.security.auth.useSubjectCredsOnly=false -jar /home/supusr/AutoVal/AutoVal_Dev.jar
usage: utility-name
-s,--ssn <arg> source system names

我从以下位置获得代码:

有人能告诉我我在这里犯了什么错误吗?
