如果要在jsp页面用java代码获取完整url，直接用页面的request获取是获取不到spring的请求地址的。
spring controller的request和请求转发后jsp request是2个不同的对象。直接上结果：
例如请求地址为：http://localhost:8080/index/test?time=1&no=2
Controller打印：
request.getScheme() = http request.getServerName() = localhost request.getServerPort() = 8080 request.getContextPath() = request.getServletPath() = /index/test request.getRequestURI() = /index/test request.getRequestURL() = http://localhost:8080/index/test request.getQueryString() = time=1&no=2 fullUrl1 = http://localhost:8080/index/test?time=1&no=2 fullUrl2 = http://localhost:8080/index/test?time=1&no=2
Jsp打印：
request.getScheme() = http request.getServerName() = localhost request.getServerPort() = 8080 request.getContextPath() = request.getServletPath() = /WEB-INF/view/index/test.jsp request.getRequestURI() = /WEB-INF/view/index/test.jsp request.getRequestURL() = http://localhost:8080/WEB-INF/view/index/test.jsp request.getQueryString() = time=1&no=2 ===================================================== req.getScheme() = http req.getServerName() = localhost req.getServerPort() = 8080 req.getContextPath() = req.getServletPath() = /index/test req.getRequestURI() = /index/test req.getRequestURL() = http://localhost:8080/index/test req.getQueryString() = time=1&no=2 fullUrl1 = http://localhost:8080/index/test?time=1&no=2 fullUrl2 = http://localhost:8080/index/test?time=1&no=2
获取完整url
String fullUrl1 = request.getScheme() + "://" + request.getServerName() + ":" + //协议 + 服务器域名
(request.getServerPort()==80 ? "" : request.getServerPort()) + //端口
request.getContextPath() + //项目的名字
request.getServletPath() + //目录下全名称
(request.getQueryString()!=null ? ("?"+request.getQueryString()) : ""); //参数
System.out.println("fullUrl1 = "+fullUrl1);
String fullUrl2 = request.getRequestURL() + (request.getQueryString()!=null ? ("?"+request.getQueryString()) : "");
System.out.println("fullUrl2 = "+fullUrl2);如果jsp获取完整url就用
HttpServletRequest req = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
IndexController.java
package com.cxq.controller;

@Controller
@RequestMapping(value = "/index")
public class IndexController {
protected Logger logger = LoggerFactory.getLogger(this.getClass());
@RequestMapping("/test")
public String test(Model model, HttpServletRequest request, HttpServletResponse response) {
System.out.println("request.getScheme() = "+request.getScheme());
System.out.println("request.getServerName() = "+request.getServerName());
System.out.println("request.getServerPort() = "+request.getServerPort());
System.out.println("request.getContextPath() = "+request.getContextPath());
System.out.println("request.getServletPath() = "+request.getServletPath());
System.out.println("request.getRequestURI() = "+request.getRequestURI());
System.out.println("request.getRequestURL() = "+request.getRequestURL());
System.out.println("request.getQueryString() = "+request.getQueryString());
String fullUrl1 = request.getScheme() + "://" + //协议
request.getServerName() + ":" + //服务器域名
(request.getServerPort()==80 ? "" : request.getServerPort()) + //端口
request.getContextPath() + //项目的名字
request.getServletPath() + //目录下全名称
(request.getQueryString()!=null ? ("?"+request.getQueryString()) : "");
System.out.println("fullUrl1 = "+fullUrl1);
String fullUrl2 = request.getRequestURL() +
(request.getQueryString()!=null ? ("?"+request.getQueryString()) : "");
System.out.println("fullUrl2 = "+fullUrl2);
return "index/test";
}
