在处理方法入参处使用@RequestParam可以把请求参数传递给请求方法。
- 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。
-
@RequestMapping(value =
"/testRequestParam")
-
public String testRequestParam(@RequestParam(value = "username") String username,
-
@RequestParam(value = "age", required = false, defaultValue = "0") int age) {
-
-
System.out.println(
"testRequestParam, username: " + username +
" , age: " + age);
-
return SUCCESS;
-
}
<a href=”testRequestParam?username=atguigu&age=11″>testRequestParam</a>
