SpringMVC中支持原生态的HttpServletRequest和HttpServletResponse等等。

SpringMVCTest.java

package com.hust.springmvc1;

import java.io.IOException;
import java.io.Writer;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

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


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

    private static final String SUCCESS = "success";

    /**
     * 可以使用 Servlet 原生的API作为目标方法的参数
     * 具体支持以下类型
     * HttpServletRequest
     * HttpServletResponse
     * HttpSession
     * java.security.Principal
     * OutputStream
     * Reader
     * Writer
     * @throws IOException 
     */
    @RequestMapping("/testServletAPI")
    public void testServletAPI(HttpServletRequest request,
            HttpServletResponse response, Writer out) throws IOException {
        System.out.println("testServletAPI, " + request + "," + response);
        // 为了测试能用原生的Servlet中的Writer，先把返回值String去掉改成void，一样能在屏幕写出String
        out.write("hello springMVC");
        // return SUCCESS;
    }
}

比较简单，基本一看都能明白。
