基本controller

package com.gavin.exam.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

//完整url  /page/test/dashboard
@Controller
@RequestMapping("/page/test")
public class TestController {

    @RequestMapping(value = "/dashboard", method = RequestMethod.GET)
    public ModelAndView viewCourseDashboard(HttpServletRequest request) {
        System.out.println("hi");
        return null;
    }
}

请求参数的接收

• @PathVariable
• @RequestParam
  (@RequestParam(value = "go", defaultValue = "") String go)
• @RequestHeader
• @RequestBody
• 使用对象直接接收
• 文件上床
