java - Spring Boot 无法识别带有发送请求参数的 Controller

Question

仅当我根据请求发送更多参数时，Spring Boot 才无法识别我的 Controller 。例如:

如果我发送正常的GET请求，Spring Boot识别我的 Controller : http://localhost/idp/oauth/123/authorize

如果我发送带有额外参数的GET请求，Spring Boot无法识别我的 Controller : http://localhost/idp/oauth/123/authorize?scope=public_profile

我需要准确接收第二个示例的请求(带有参数范围)，但 Spring Boot 无法识别 Controller 并重定向到/error。

代码:

@Controller
@RequestMapping("/idp/oauth")
public class OAuthController {

    @RequestMapping(value = "/{clientId}/authorize", method = RequestMethod.GET)
    public String authorizeGet(
            HttpServletRequest request, 
            HttpServletResponse response, 
            @PathVariable String clientId,
            Model model) {
            // ...
    }

    @RequestMapping(value = "/{clientId}/authorize", method = RequestMethod.POST)
    public String authorizePost(
            HttpServletRequest request, 
            HttpServletResponse response, 
            @PathVariable String clientId,
            Model model) {
            // ...
    }
}

Answer 1

由于您传递了名为“scope”的额外参数，Spring 将在方法中搜索 @RequestParam 它找不到任何内容，因此出现错误

您需要修改您的方法以添加所有@RequestParam

如果可选字段不是必需的，您还可以添加 required = false

@RequestMapping(value = "/{clientId}/authorize", method = RequestMethod.GET)
public String authorizeGet(
        HttpServletRequest request, 
        HttpServletResponse response, 
        @PathVariable String clientId,
        @RequestParam(value = "scope") String scope,
        @RequestParam(required = false, value = "optionalParam") String optionalParam,
        Model model) {
        // ...
}
