java - 从 HttpServletRequest 转换为 WebRequest

Question

我使用 Spring Initializer、嵌入式 Tomcat、Thymeleaf 模板引擎生成了一个 Spring Boot Web 应用程序，并将其打包为可执行 JAR 文件。

使用的技术:

Spring Boot 2.0.0.M6、Java 8、行家

我在类(class)的 1 中有这个方法

private Map<String, Object> getErrorAttributes(HttpServletRequest request,
                                                   boolean includeStackTrace) {

        RequestAttributes requestAttributes = new ServletRequestAttributes(request);
        return this.errorAttributes.getErrorAttributes(request, includeStackTrace)

    }

但我不知道如何从 javax.servlet.http HttpServletRequest org.springframework.web.context.request.WebRequest

The method getErrorAttributes(WebRequest, boolean) in the type ErrorAttributes is not applicable for the arguments (HttpServletRequest, 
     boolean)

Answer 1

您不需要将 HttpServletRequest 转换为 WebRequest。您需要在 Controller 方法中使用 WebRequest。

@GetMapping("/endpoint")
public .. endpont(HttpServletRequest request, WebRequest webRequest) {
    getErrorAttributes(request, webRequest, true);
}

然后更改为您的 getErrorAttributes 方法

private Map<String, Object> getErrorAttributes(HttpServletRequest request, WebRequest webRequest,
                                               boolean includeStackTrace) {

    RequestAttributes requestAttributes = new ServletRequestAttributes(request);
    return this.errorAttributes.getErrorAttributes(webRequest, includeStackTrace)

}
