Shell腳本無法完全從Java執行

Question

我有一個shell腳本，它可以執行sql構建工作。

從UNIX提示符手動調用它時，它正在執行並給出預期的結果。

但是，當從Java調用相同命令時，它並沒有完全執行。

手動執行：

MODIFY_PATCH_CREATION.ksh 118765 CP_14052906_28112015134449_16

日志文件顯示為：

Installing Patch for BATCH ID:118765 and PATCH NAME:CP_14052906_28112015134449_16
CP_14052906_28112015134449_16_RELEASE directory has been created
CP_14052906_28112015134449_16_INSTALL directory has been created
CP_14052906_28112015134449_16_ROLLBACK directory has been created
SQL and LOG directories have been created for INSTALL
INSTALL script is created
SQL and LOG directories have been created for ROLLBACK
ROLLBACK script is created
SQL files are created for INSTALL
SQL files are created for ROLLBACK
Patch installed Successfully..

但是，如果我從java程序執行相同的操作，如下所示：

Java代碼：

public class ShellTest{


        public static void main(String a[]) throws Exception{


                System.out.println("Hello kp");
                Runtime.getRuntime().exec("MODIFY_PATCH_CREATION.ksh 118765 CP_14052906_28112015134449_16");


        }

}

作為java ShellTest執行時，日志僅在某種程度上出現

Installing Patch for BATCH ID:118765 and PATCH NAME:CP_14052906_28112015134449_16

我有些奇怪 請幫忙。

Answer 1

該腳本具有未定向到日志的echo語句，但是您的Java程序沒有使用腳本進程的輸出，因此一旦輸出緩沖區已滿，腳本將停頓。

如果您希望腳本輸出進入控制台，即與Java程序輸出相同的輸出目的地，則需要使用ProcessBuilder.inheritIO() 。

無論如何，您都應該使用ProcessBuilder 。 引用Process javadoc：

默認情況下，創建的子進程沒有自己的終端或控制台。 其所有標准I / O（即stdin，stdout，stderr）操作都將重定向到父進程，在此可以通過使用getOutputStream() ， getInputStream()和getErrorStream()方法獲得的流來訪問它們。 父流程使用這些流將輸入饋入子流程並從子流程獲取輸出。 由於某些本機平台僅為標准輸入和輸出流提供有限的緩沖區大小，因此未能及時寫入子流程的輸入流或讀取子流程的輸出流可能導致子流程阻塞甚至死鎖。

如果需要， 還可以使用ProcessBuilder類的方法來重定向子流程I / O。

從1.5版本開始， ProcessBuilder.start()是創建Process的首選方法。
