springboot-springmvc-requestParam

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;
}
