Spring MVC 4值传递

@RequestParam

在方法声明的参数处可以使用@RequestParam把客户端提交的请求中的参数传递给方法

@RequestMapping(value = "/testRequestParam")
public String testRequestParam(@RequestParam(value = "username") String un,
@RequestParam(value = "age", required = false, defaultValue = "0") int age) {
System.out.println("testRequestParam, username: " + un + ", age: " + age);
return SUCCESS;
}

@RequestHeader

用法与@RequestParam相同可以获取头信息中的参数的值

@RequestMapping("/testRequestHeader")
public String testRequestHeader(@RequestHeader(value = "Accept-Language") String al) {
System.out.println("testRequestHeader, Accept-Language: " + al);
return SUCCESS;
}

@CookieValue

获取Cookie中的值

@RequestMapping("/testCookieValue")
public String testCookieValue(@CookieValue("JSESSIONID") String sessionId) {
System.out.println("testCookieValue: sessionId: " + sessionId);
return SUCCESS;
}
