Spring Boot-请求映射将不接受尾部斜杠或多个目录

在控制器中使用RequestMapping时,我可以将html文件映射到“ /”,另一个映射到“ / users”。但是,尝试映射到“ / users /”或“ / users / test”将不起作用。在控制台中,它将说端点已映射,但是在尝试访问它时,我会看到404错误页面。

package com.bridge.Bitter.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class BitterController {

    //works
    @RequestMapping(value="/")
    public String getMainPage(){
        return "main.html";
    }

    //works
    @RequestMapping(value="/users")
    public String getUsersPage(){
        return "users.html";
    }

    //doesn't work, Whitelabel error page
    @RequestMapping(value="/users/")
    public String getUsersSlashPage(){
        return "users.html";
    }
    //doesn't work, Whitelabel error page
    @RequestMapping(value="/users/test")
    public String getUsersTestPage(){
        return "users.html";
    }

}

我的application.properties仅包含“ spring.data.rest.basePath = / api”。

如果我从@Controller更改为@Rest Controller,则会发生以下情况:

package com.bridge.Bitter.controllers;

import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;

@RestController
public class BitterController {

    //works
    @RequestMapping(value="/")
    public String getMainPage(){
        return "main.html";
    }

    //returns a webpage with the text "users.html" on it instead of serving the html
    @RequestMapping(value="/users")
    public String getUsersPage(){
        return "users.html";
    }

    //returns a webpage with the text "users.html" on it instead of serving the html
    @RequestMapping(value="/users/")
    public String getUsersSlashPage(){
        return "users.html";
    }
    //returns a webpage with the text "users.html" on it instead of serving the html
    @RequestMapping(value="/users/test")
    public String getUsersTestPage(){
        return "users.html";
    }

}

将函数从返回字符串更改为返回

new ModelAndView("user.html")

适用于/ users,但是适用于/ users /和/ users / test的404错误。

您尝试两次映射相同的路径。 / users与/ users /相同,因此Spring无法解析哪个控制器方法应处理请求。

您可以尝试以下操作:

package com.bridge.Bitter.controllers;

import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class BitterController {

    @RequestMapping("/")
    public String getMainPage(){
        return "main.html";
    }

    @RequestMapping("/users")
    public String getUsersPage(){
        return "users.html";
    }

    @RequestMapping("/users/test")
    public String getUsersTestPage(){
        return "users.html";
    }
}

另一方面,当您使用@RestController annotation时,总是返回JSON格式的响应文本,这就是为什么总是得到相同结果的原因。
