shell脚本未完全从java执行

Question

我有一个shell脚本，它执行sql构建工作。

当从unix提示符手动调用它时，它正在执行并按预期给出结果。

但是当它从java调用时，它并没有完全执行。

手动执行：

MODIFY_PATCH_CREATION. ksh 118765CP_14052906_28112015134449_16

日志文件显示为：

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..

但是如果我从java程序执行相同的操作，如下所示：

Java代码：

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");


        }

}

当作为java ShellTest执行时，日志只在一定程度上出现

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

对我来说有些奇怪。请帮忙。

Answer 1

脚本有echo语句，这些语句没有指向日志，但Java程序没有使用脚本进程的输出，因此一旦输出缓冲区满了，脚本就会暂停。

如果希望脚本输出到控制台，即到与Java程序输出相同的输出目标，则需要使用ProcessBuilder。inheritIO（）。

无论如何，您应该使用ProcessBuilder。引用流程的javadoc：

默认情况下，创建的子流程没有自己的终端或控制台。它的所有标准I/O（即stdin、stdout、stderr）操作都将重定向到父进程，在父进程中，可以通过使用方法获取的流来访问它们，这些方法包括。父进程使用这些流向子进程馈送输入并从中获取输出。由于某些本机平台仅为标准输入和输出流提供有限的缓冲区大小，如果不能及时写入子进程的输入流或读取子进程的输出流，可能会导致子进程阻塞，甚至死锁。

如果需要，还可以使用ProcessBuilder类的方法重定向子进程I/O。

从1.5开始，ProcessBuilder。start（）是创建流程的首选方法。
