读取配置文件的代码:
package com.util;
import java.io.file;
import java.io.fileinputstream;
import java.io.ioexception;
import java.io.inputstream;
import java.util.properties;
public class loadproperties {
public static properties getproperties() {
file file = new file(class.class.getclass().getresource("/").getpath()
+ "properties.properties");
inputstream inputstream = null;
try {
inputstream = new fileinputstream(file);
} catch (ioexception e) {
// todo auto-generated catch block
e.printstacktrace();
}
properties properties = new properties();
try {
properties.load(inputstream);
} catch (ioexception e) {
// todo auto-generated catch block
e.printstacktrace();
}
return properties;
}
}
代码目录结构:
测试运行时配置文件放在项目的bin目录下(打包成可运行jar文件的时候要删除,打包完成后将配置文件和jar包放在同级目录下即可):
properties.properties
ip= user= pwd= port=22 privatekeypath= passphrase= sourcepath= destinationpath=/home/dbbs/f
打包可运行jar文件:
export->java->runnabe jar file
完成后
在控制台运行java -jar 导出jar包的名字.jar 即可
