1、 新建RestFulController类并编写
package com.kuang.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class RestFulController { @RequestMapping("/add") public String test1( int a, int b, Model model){ int res = a + b; model.addAttribute("msg","结果为"+res); return "test"; } }
2、运行测试
3、传统的方法给它赋值参数
重新编写RestFulController类
package com.kuang.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class RestFulController { @RequestMapping("/add/{a}/{b}") public String test1(@PathVariable int a, @PathVariable int b, Model model){ int res = a + b; model.addAttribute("msg","结果为"+res); return "test"; } }
package com.kuang.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class ModelTest1 { //转发方式一 @RequestMapping("m1/t1") public String test1(Model model){ model.addAttribute("msg","ModelTest1"); return "/WEB-INF/jsp/test.jsp"; } //转发方式二:forward: @RequestMapping("/m2/t2") public String test2(){ return "forward:/index.jsp"; } //重定向 @RequestMapping("/rsm/t3") public String test3(){ return "redirect:/index.jsp"; } }
访问m1/t1路径,可以转发到WEB-INF/jsp/test.jsp
