Java在WEB项目中获取文件路径

Java在WEB项目中获取文件路径

1. 根目录所对应的绝对路径：request.getRequestURI()
2. 得到工程名：request.getContextPath();
3. 根目录所对应的绝对路径：path1 = request.getServletPath()
4. 得到工程目录：request.getSession().getServletContext().getRealPath("")
   注：参数可具体到包名。
5. 得到浏览器地址栏地址：request.getRequestURL()

测试代码如下

package cn.com.mydemo.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @Description 登录Controller
 * @author jjy
 * @Creation 2019-02-21
 */
@Controller
public class LoginController {
	
	/**
	 * @Description 获取路径
	 * @param request
	 * @return
	 * @Creation 2019-04-04 by jjy
	 */
	@RequestMapping(value = "/getPath")
	public String getPath(HttpServletRequest request) {
		//根目录所对应的绝对路径
		String path1 = request.getRequestURI();
		System.out.println("request.getRequestURI() = " + path1);
		//得到工程名
		path1 = request.getContextPath();
		System.out.println("request.getContextPath() = " + path1);
		//根目录所对应的绝对路径
		path1 = request.getServletPath();
		System.out.println("request.getServletPath() = " + path1);
		//得到工程目录
		path1 = request.getSession().getServletContext().getRealPath("");//参数可具体到包名。
		System.out.println("request.getSession().getServletContext().getRealPath(\"\") = " + path1);
		//得到浏览器地址栏地址
		StringBuffer path2 = request.getRequestURL();
		System.out.println("request.getRequestURL() = " + path2.toString());
		
		return "success";
	}
}

结果
