从部署在cloudfoundry上的spring web应用程序执行shell脚本 [英] Execute shell script from spring web application deployed on cloudfoundry

问题描述

我试图从部署在cloudfoundry上的Spring Web应用程序调用Btrace脚本。

I am trying to call Btrace script from Spring web application deployed on cloudfoundry.

执行命令是/ var / vcap / data / dea / apps / petclinic- 0-fef4b0e052097a0cd2bedb8018c28dcd / tomcat / webapps / ROOT / WEB-INF / classes / bin / btrace.sh 532 / var / vcap / data / dea / apps / petclinic-0-fef4b0e052097a0cd2bedb8018c28dcd / tomcat / WEB-INF /bin/DatabaseQueries.java

The execution command is /var/vcap/data/dea/apps/petclinic-0-fef4b0e052097a0cd2bedb8018c28dcd/tomcat/webapps/ROOT/WEB-INF/classes/bin/btrace.sh 532 /var/vcap/data/dea/apps/petclinic-0-fef4b0e052097a0cd2bedb8018c28dcd/tomcat/webapps/ROOT/WEB-INF/classes/bin/DatabaseQueries.java

但是我收到此错误：

java.io.IOException：无法运行程序 /var/vcap/data/dea/apps/petclinic-0-fef4b0e052097a0cd2bedb8018c28dcd/tomcat/webapps/ROOT/WEB-INF/classes/bin/btrace.sh：java.io.IOException：错误= 13，权限被拒绝

java.io.IOException: Cannot run program "/var/vcap/data/dea/apps/petclinic-0-fef4b0e052097a0cd2bedb8018c28dcd/tomcat/webapps/ROOT/WEB-INF/classes/bin/btrace.sh": java.io.IOException: error=13, Permission denied

我以完全的脚本编写权限推送了应用程序，但错误仍然存​​在。

I push the app with full permissions to script but error persists.

我们如何执行shell /来自cloudfoundry上的spring Web应用程序的bat脚本

How can we execute a shell/bat script from spring web application on cloudfoundry

推荐答案

推送到Cloud Foundry的文件的权限由文件所有者读取/写入。在运行脚本之前，您需要使脚本可从您的应用程序执行：

Permissions on files pushed to Cloud Foundry are read/write by the file owner. You'll need to make the script executable from your app before running it:

String btracePath = System.getenv().get("HOME") + "/tomcat/webapps/ROOT/WEB-INF/classes/bin/btrace.sh";
String cmd = "chmod +x " + btracePath;
Runtime run = Runtime.getRuntime();
Process pr = run.exec(cmd);
try {
    pr.waitFor();
} catch (InterruptedException ex) {
    ex.printStackTrace();
}
