Spring Batchの戻り値をshellで取る

Spring Batchの戻り値を取れずにクソレベルにハマった

単純に、Shellからjavaコマンドでバッチを起動して、$?で取りたかっただけ
ExitStatusをグリグリ弄ったところでうまくいかない、結局、中のコード見たら、BatchStatusと何かの関連で決まるようなコードを見かけたので
module-context.xmlあたりにSimpleJvmExitCodeMapperのbeanを突っ込んで

 
   <!-- exitCodeMapper -->
   <bean class="org.springframework.batch.core.launch.support.SimpleJvmExitCodeMapper" id="exitCodeMapper"/>

@Autowiredした

public class KusoTasklet implements Tasklet, InitializingBean {
 @Autowired
 private SimpleJvmExitCodeMapper sm;
...

で、@Autowiredしたクラスあたりで、ExitStatus.COMPLETEDの値を書き換える

...
    protected void setResultCode(Integer result) {
        Map<String, Integer> exitCodeMap = new HashMap<String, Integer>();
        exitCodeMap.put(ExitStatus.COMPLETED.getExitCode(), result);
        sm.setMapping(exitCodeMap);
    }
...

やってみた

resultへ任意の数字を仕込めばshellの戻り値になる


ググったら、ここに 書いてあるじゃないか。。。

なかのコード見てる暇あったら、みんなググロー、１日無駄になった...
