在index.jsp中加
<a href="controller/testRequestParam?username=gu&age=20">TestRequestParam</a>
HelloController
//测试@RequestParam
@RequestMapping(value = "/testRequestParam")
public String testRequestParam(@RequestParam(value = "username") String username, @RequestParam(value = "age", required = false, defaultValue = "0") Integer age) {
System.out.printf("testParam, username: " + username + ", age: " +age);
return "Hello";
}
@RequestParam来映射请求参数
value 值即请求参数的参数名
required 该参数是否必须，默认为true
defaultValue 请求参数的默认值
