使用Servlet原生API作为方法的参数

1、SpringMVC的Handler方法可以接受以下ServletAPI类型的参数：
（1）HttpServletRequest
（2）HttpServletResponse
（3）HttpSession
（4）java.security.Principal
（5）Locale
（6）InputStream
（7）OutputStream
（8）Reader
（9）Writer

2、控制器TestRequestMappingController.java

package com.springmvc.web.controller;

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

@Controller
@RequestMapping("/springmvc")
public class TestRequestMappingController {

	@RequestMapping("testServletAPI")
	public String testServletAPI(HttpServletRequest request,
			HttpServletResponse response) {
		String username = request.getParameter("username");
		System.out.println("testServletAPI, username="+username);
		return "success";
	}	
	
}

3、访问代码

<a href="<%=path%>/springmvc/testServletAPI?username=lps">Test ServletAPI</a>
