스프링 배치 shell - seupeuling baechi shell

Hudson 의 Execution Shell에 java command 쓰다가 하루 시간이 다 가므로.. 스크립트를 만들어서 쓰면 많이 편리하다. serivce project 이름, xml 파일 이름, define한 job 이름, 저장할 table의 prefix, 기타 덧붙일 스트링이 있으면 사용하기 편할 수 있다.

Spring Batch의 CommandLineJobRunner 처럼 클래스를 하나 만듬

(http://www.docjar.com/html/api/org/springframework/batch/core/launch/support/CommandLineJobRunner.java.html)

Hello guys, in this post we will explore how to find the solution to Use shell Command in Spring Batch SystemCommandTasklet Code examples in programming.

public ExitStatus processFile(String fileName, String workingDir) throws InterruptedException, IOException {
        boolean isWindows = System.getProperty("os.name").toLowerCase().startsWith("windows");
        logger.info("OS windows {} :", isWindows);
        String command = String.format("tail -1 %s > input_footer.txt && head -n -1 %s > input_body.txt", fileName, fileName);
        logger.info("command {} and working dir{} :", command, workingDir);
        ProcessBuilder builder = new ProcessBuilder();
        builder.command(bashPath, "-c", command);
        builder.directory(new File(workingDir));
        Process process = builder.start();
        StreamGobbler streamGobbler =
                new StreamGobbler(process.getInputStream(), System.out::println);
        Executors.newSingleThreadExecutor().submit(streamGobbler);
        int exitCode = process.waitFor();
        ExitStatus status = exitCode == 0 ? ExitStatus.COMPLETED : ExitStatus.FAILED;
        return status;
    }
 public MethodInvokingTaskletAdapter preProcessFileAdapter(@Value("#{jobExecutionContext['customerFile']}") String file, PreProcessFile preProcessFile)
    {
        String workingDir = FilenameUtils.getFullPath(file);
        String fileName = FilenameUtils.getName(file);
        MethodInvokingTaskletAdapter methodInvokingTaskletAdapter=new MethodInvokingTaskletAdapter();
        methodInvokingTaskletAdapter.setTargetObject(preProcessFile);
        methodInvokingTaskletAdapter.setTargetMethod("processFile");
        methodInvokingTaskletAdapter.setArguments(new String[]{fileName,workingDir});
 return methodInvokingTaskletAdapter;
    }

Many examples helped us understand how to fix the Use shell Command in Spring Batch SystemCommandTasklet Code examples error.
