springmvc之使用@RequestParam绑定请求参数

@RequestMapping("/springmvc")
@Controller
public class SpringmvcTest {
    private static final String SUCCESS = "success";
    
    @RequestMapping(value="/testRequestParam",method=RequestMethod.GET)
    public String testRequestParam(@RequestParam(value="username") String username,
            @RequestParam(value="age",required=false,defaultValue="0") Integer age) {
        System.out.println("username="+username+","+"age="+age);
        return SUCCESS;
    }
}

<a href="springmvc/testRequestParam?username=tom&age=18">testRequestParam</a>
