通过@PathVariabl注解获取路径中传递参数

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; }
JAVA controller
@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
@RequestMapping(value= " /requestParam " , method= RequestMethod.GET) public String setupForm(@RequestParam( " a " ) String a, ModelMap model) { System.out.println(a); return " helloWorld " ;}
