1.概述
java 执行shell
2.utils类
package com.shell.java;
import java.io.InputStreamReader;
import java.io.LineNumberReader;
public class JaveShellUtil {
public static int ExecCommand(String command) {
int retCode = 0;
try {
Process process = Runtime.getRuntime().exec( command,null,null);
retCode = process.waitFor();
ExecOutput(process);
} catch (Exception e) {
e.printStackTrace();
retCode = -1;
}
return retCode;
}
public static boolean ExecOutput(Process process) throws Exception {
if (process == null) {
return false;
} else {
InputStreamReader ir = new InputStreamReader(process.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
String line;
String output = "";
while ((line = input.readLine()) != null) {
output += line + "\n";
}
input.close();
ir.close();
if (output.length() > 0) {
System.out.println(output);
}
}
return true;
}
public static int execuCommonWithParam(String command) {
int retCode = 0;
try {
Process process = Runtime.getRuntime().exec(new String[] {
"/bin/sh", "-c", command }, null, null);
retCode = process.waitFor();
ExecOutput(process);
} catch (Exception e) {
retCode = -1;
}
return retCode;
}
}
测试类如下
package com.shell.java;
import org.junit.Test;
/**

*/
public class JaveShellUtilTest {
/**
* 不传参测试
*/
@Test
public void execCommand() {
String command= "chmod 777 /opt/workspace/demo.sh ";
//需要传递的就是shell脚本的位置
int retCode=JaveShellUtil.ExecCommand(command);
System.out.println(retCode+" retCode");
if(retCode==0){
System.out.println("success.....");
}else{
System.out.println("error.....");
}
}
/**

*/
@Test
public void execCommand1() {
String command= "/bin/sh /opt/workspace/demo.sh lcc xjj ";
//需要传递的就是shell脚本的位置
int retCode=JaveShellUtil.ExecCommand(command);
System.out.println(retCode+" retCode");
if(retCode==0){
System.out.println("success.....");
}else{
System.out.println("error.....");
}
}
/**

//需要传递的就是shell脚本的位置
int retCode=JaveShellUtil.execuCommonWithParam(command);
System.out.println(retCode+" retCode");
if(retCode==0){
System.out.println("success.....");
}else{
System.out.println("error.....");
}
}
}
