最近的新项目有多个地方需要调用shell脚本,这里记录下简单的shell脚本调用方法。代码如下:
private void callSh() {
InputStreamReader stdISR = null;
InputStreamReader errISR = null;
Process process = null;
//调用的脚本及路径
String command = "/home/mw/weblogic/test.sh";
try {
process = Runtime.getRuntime().exec(command);
BufferedReader stdBR = new BufferedReader(new InputStreamReader(process.getInputStream()));
BufferedReader errBR = new BufferedReader(new InputStreamReader(process.getErrorStream()));
String line = "";
while ((line = stdBR.readLine()) != null) {
System.out.println("STD line:" + line);
}
while ((line = errBR.readLine()) != null) {
System.out.println("ERR line:" +line);
}
} catch (Exception e) {
throw new BusinessException("执行脚本失败===="+e);
}finally{
if(stdBR != null){
stdBR.close();
}
if(errBR != null){
errBR.close();
}
if(process != null){
process.destroy();
}
}
}
此代码只适用一般的shell脚本调用,如果shell脚本内容比较多,语法比较复杂,因为没有很好的容错机制,使用此方式可能就会出现问题。这里看过一篇文章,可借鉴:
