问题描述
我的Java程序是从Windows脚本中调用的.
My Java program is called from a windows script.
在仍从JAR文件加载类文件的同时，是否可以使用Java退出代码来确定Java程序是否由于磁盘空间不足而提前终止?
Is it possible to use the Java exit code to determine whether the Java program was terminated prematurely due to out of disk space while it is still loading the class files from the JAR file?
我尝试了内存不足异常，它返回退出代码1，但磁盘空间不足则返回退出代码0.这是正确的行为吗?
I tried out of memory exception and it returns an exit code 1 but out of disk space returns exit code 0. Is this correct behaviour?
子类方法:
public int executeBatch() {
logger.info("executeBatch() - Send Email Alert Start");
try {
alertTransactionMgr.sendEmailAlert();
} catch (Exception e) {
throw new Exception(e);
}
logger.info("executeBatch() - Send Email Alert End");
return 0;
}
父方法:
public int execute() {
this.trx = createTransaction();
try {
returnCode = executeBatch();
} catch (Exception e) {
printLogErrorMsg("Job Failed caused by the Exception.", e);
returnCode = -1;
trx.setStatus("Failure");
updateBatchTransaction(trx);
}
return returnCode;
}

推荐答案
您的批处理文件已损坏. ERRORLEVEL永远不会为空，除非其中有些愚蠢的操作(例如将其设置为字符串)，否则它总是包含数字.
Your batch file is broken. ERRORLEVEL is never empty, it's always got a number in it, unless you do something stupid like set it to a string.
@echo off
set ERRLVL=0
java -cp %CLASSPATH% com.test.runner.MainBatchRunner
@rem if not (%ERRORLEVEL%)==() (
@rem set ERRLVL=%ERRORLEVEL%
@rem)
if %ERRORLEVEL% != 0 set ERRLVL=%ERRORLEVEL%
echo Delete Files that are more than 30 old
forfiles /p "%BATCH_LOG_DIR%" /s /m %2*.log /d -%ARCHIVE_DAYS% /c "cmd /c echo del %BATCH_LOG_DIR%\@file"
forfiles /p "%BATCH_LOG_DIR%" /s /m %2*.log /d -%ARCHIVE_DAYS% /c "cmd /c del %BATCH_LOG_DIR%\@file"
echo Program exit %ERRLVL%
echo Program exit %ERRLVL% >> %BATCH_LOG_FILE%
exit /B %ERRLVL%
