Spring - 基于注释的控制器 - 基于查询字符串的请求映射 [英] Spring - Annotation Based Controller - RequestMapping based on query string

问题描述

在Spring基于注解的控制器中，是否可以使用@RequestMapping将不同的查询字符串映射到不同的方法上?

In Spring annotation-based controller, is it possible to map different query strings using @RequestMapping to different methods?

例如

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


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

推荐答案

是的，你可以使用 params 元素:

Yes, you can use the params element:

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

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

您甚至可以根据参数的存在或不存在进行映射:

You can even map based on the presence or absence of a param:

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

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