Spring - 基于注释的控制器 - 基于查询字符串的RequestMapping

Question

在基于Spring注释的控制器中,是否可以使用@RequestMapping不同的方法映射不同的查询字符串？

例如

@RequestMapping("/test.html?day=monday")
public void writeMonday() {
}


@RequestMapping("/test.html?day=tuesday")
public void writeTuesday() {
}

Answer 1

是的,你可以使用params元素:

@RequestMapping("/test.html", params = "day=monday")
public void writeMonday() {
}

@RequestMapping("/test.html", params = "day=tuesday")
public void writeTuesday() {
}

你甚至可以在地图基础上,存在或不存在一个特性参数的:

@RequestMapping("/test.html", params = "day")
public void writeSomeDay() {
}

@RequestMapping("/test.html", params = "!day")
public void writeNoDay() {
}

Answer 2

或者你可以这样做:

@RequestMapping("/test.html")
public void writeSomeDay(@RequestParam String day) {
   // code to handle "day" comes here...
}
