springmvc请求方式
1、直接写在形参中：基本类型
@RequestMapping("/testRequestParam1")
public ModelAndView testRequestParam1(String name) {
ModelAndView mv = new ModelAndView();
System.out.println(name);
mv.setViewName("helloworld");
return mv;
}
2、直接写在形参中：pojo
/**
* 页面请求实例：
* <form action="http://localhost:8080/hello/testRequestParam4" method="post">
* <input type="text" name="id"/> <input type="text" name="name"/>
* <input type="submit" value="提交"/> </form>
*/
@RequestMapping("/testRequestParam4")
public ModelAndView testRequestParam4(T1 t) {
System.out.println(t.getId());
ModelAndView mv = new ModelAndView();
mv.setViewName("helloworld");
return mv;
}
3、通过@RequestParam写在形参中
@RequestMapping("/testRequestParam2")
public ModelAndView testRequestParam2(@RequestParam(value = "id") Integer id) {
ModelAndView mv = new ModelAndView();
System.out.println(id);
mv.setViewName("helloworld");
return mv;
}
4、通过@PathVariable写在形参中
@RequestMapping("/testRequestParam3/{id}")
public ModelAndView testRequestParam3(@PathVariable("id") Integer id) {
ModelAndView mv = new ModelAndView();
System.out.println(id);
mv.setViewName("helloworld");
return mv;
}
