從HttpServletRequest中獲得各種路徑的小結

工作中用的是SSM的框架,在Controller層中我們經常需要對傳過來的HttpServletRequest 進行操作,下面總結了一些通過HttpServletRequest 獲得各種路徑的方法:

package cn.com.kingc.eoms.controller;

import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/Upload")
public class FileUploadController {
    @RequestMapping(value = "/fileUpload")
    @ResponseBody
    public void upload(@RequestBody HttpServletRequest request) {
 //       假設請求的url為http://127.0.0.1:8080/EOMS/Upload/fileUpload
        String LocalAddr = request.getLocalAddr();//       返回伺服器ip
                           request.getRemoteAddr();//      返回客戶機ip

        String path1 = request.getContextPath();
        System.out.println(path1);                //       /EOMS

        String servletPath = request.getServletPath();
        System.out.println(servletPath);          //      /Upload/fileUpload

        String realPath = request.getServletContext().getRealPath("/");                  
        System.out.println(realPath);            //      G:\apache-tomcat-8.0.45\webapps\EOMS

        request.getServletContext().getRealPath("/WEB-INF");//G:\apache-tomcat-8.0.45\webapps\EOMS\WEB-INF

    }
}
