java action读取src目录下的properties配置文件。
mailServer.properties配置文件如下:
mailServerHost = smtp.163.com
mailServerPort = 25
authValidate = true
userName = test@163.com
读取配置文件类GetProperty代码如下:
package com.hsinghsu.test.action;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
public class GetProperty {
// 方法一:通过java.util.ResourceBundle读取资源属性文件
public static String getPropertyByName(String path, String name) {
String result = "";
try {
// 方法一:通过java.util.ResourceBundle读取资源属性文件
result = java.util.ResourceBundle.getBundle(path).getString(name);
System.out.println("name:" + result);
} catch (Exception e) {
System.out.println("getPropertyByName2 error:" + name);
}
return result;
}
// 方法二:通过类加载目录getClassLoader()加载属性文件
public static String getPropertyByName2(String path, String name) {
String result = "";
// 方法二:通过类加载目录getClassLoader()加载属性文件
InputStream in = GetProperty.class.getClassLoader()
.getResourceAsStream(path);
// InputStream in =
// this.getClass().getClassLoader().getResourceAsStream("mailServer.properties");
// 注:Object.class.getResourceAsStream在action中调用报错,在普通java工程中可用
// InputStream in =
// Object.class.getResourceAsStream("/mailServer.properties");
Properties prop = new Properties();
try {
prop.load(in);
result = prop.getProperty(name).trim();
System.out.println("name:" + result);
} catch (IOException e) {
System.out.println("读取配置文件出错");
e.printStackTrace();
}
return result;
}
}

}
