java中读xml文件，获取文件本身所在的磁盘位置

获取文件本身所在的磁盘位置

1.Class.getResource("")方法 http://blog.csdn.net/a15501628162/article/details/24326383
2.在通过servlet中的request获得

request.getServletContext();

ServletContext servletContext=request.getServletContext();

String realPath = servletContext.getRealPath("/WEB-INF/classes/Adress.xml");

File f = new File(realPath);

2.XmlObject.java

package edu.cslg.huachen.util;

public class XmlObject {

private String pro;

private String city;

private String jxs;

public String getPro() {

return pro;

}

public void setPro(String pro) {

this.pro = pro;

}

public String getCity() {

return city;

}

public void setCity(String city) {

this.city = city;

}

public String getJxs() {

return jxs;

}

public void setJxs(String jxs) {

this.jxs = jxs;

}

}

// request.getServletContext();

// ServletContext servletContext=request.getServletContext();

// 2.在action中读取

// ServletContext servletContext = ServletActionContext.getServletContext();

// servletContext = servletContext.getRealPath("/WEB-INF/classes/Adress.xml");

// 2.通过Class.getResource("")方法 读取
