使用脚本运行程序读取.properties文件

1）.properties文件

name=xiaoxiage=24

2）读取代码

import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.IOException;import java.io.InputStream;import java.util.Properties;public class PropertiesTest {private Properties defaultProperties = new Properties();public PropertiesTest(){}private void getProperties(String properties){try {InputStream in = new FileInputStream(properties);this.defaultProperties.load(in);in.close();String name = this.defaultProperties.getProperty("name");System.out.println("name: " + name);int age = Integer.valueOf(this.defaultProperties.getProperty("age"));System.out.println("age: " + age);} catch (FileNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}public static void main(String[] args){if ((args == null) || (args.length == 0)) {System.out.println("java -jar propertiesTest.jar [属性文件]");return;}String TEST_HOME = null;try {TEST_HOME = System.getenv("TEST_HOME");} catch (Exception e) {}String testPro = args[0];System.out.println("testPro: " + testPro);String properties = TEST_HOME + File.separator + "conf" + File.separator + "pro.properties"PropertiesTest1 pt = new PropertiesTest1();pt.getProperties(properties);}}

3）运行脚本文件start.sh

#!/bin/bash#TEST_HOME="/home/logmonitor/LogStat"export TEST_HOME=/home/xiaoxi/testTESTPRO="hello"echo "java -jar $TEST_HOME/core/providerLogMonth.jar $TESTPRO"nohup java -jar $TEST_HOME/core/providerLogMonth.jar $TESTPRO > $TEST_HOME/log/test.log 2>&1 &

4）输出结果

testPro: helloname: xiaoxiage: 24

注：

1）将程序打成 jar包和pro.properties文件添加到Linux服务器上；

2）使用脚本start.sh运行程序，sh start.sh；

3）TESTPRO为运行程序时添加的参数；

4）程序将TEST_HOME作为环境变量读取，TEST_HOME = System.getenv("TEST_HOME")；

5) File.separetor为文件分隔符；

6）脚本中echo为运行程序时的回显语句；

7）如果脚本是在Windows环境先编写的放到Linux环境时需执行dos2unix start.sh命令转换编码格式；
