用@ModelAttribute注解获取POST请求的FORM表单数据
JSP
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 " ;}
