@RequestMapping(value= " /{id}/{str} " )
public ModelAndView helloWorld(@PathVariable String id, @PathVariable String str) {
System.out.println(id);
System.out.println(str);
return new ModelAndView( " /helloWorld " );
}
用@ModelAttribute注解获取POST请求的FORM表单数据
JSP
<form method="post" action="hao.do"> a: <input id="a" type="text" name="a"/> b: <input id="b" type="text" name="b"/> <input type="submit" value="Submit" /> </form>
Java pojo
public class Pojo{
private String a;
private int b;
}
@RequestMapping(method= RequestMethod.POST)
public String processSubmit(@ModelAttribute( " pojo " ) Pojo pojo) {
return " helloWorld " ;
}
直接用HttpServletRequest获取
JAVA
@RequestMapping(method= RequestMethod.GET)
public String get(HttpServletRequest request, HttpServletResponse response) {
System.out.println(request.getParameter( " a " ));
return " helloWorld " ;
}
用注解@RequestParam绑定请求参数a到变量a
当请求参数a不存在时会有异常发生,可以通过设置属性required=false解决,
例如: @RequestParam(value="a", required=false)
JAVA
