Java 从HttpServletRequest转换为WebRequest

我已经使用Spring初始值设定项、嵌入式Tomcat、Thymeleaf模板引擎和作为可执行JAR文件的包生成了一个Spring引导web应用程序

使用的技术：

弹簧靴2.0.0.M6，Java 8，maven

我在班上的第一节课上有这个方法

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

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

    }

您不需要将

HttpServletRequest

强制转换为

WebRequest

。您需要的是在控制器方法中使用

WebRequest

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

并更改为

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)

}

私有映射getErrorAttributes（HttpServletRequest请求、WebRequest WebRequest、，
布尔值（includeStackTrace）{
RequestAttributes RequestAttributes=新的ServletRequestAttributes（请求）；
返回此.errorAttributes.getErrorAttributes（webRequest，includeStackTrace）
}

您可以删除RequestAttributes RequestAttributes=new ServletRequestAttributes（请求）；以及getErrorAtributes的HttpServletRequest如果任何人仍然有兴趣从HttpServletRequest获得

WebRequest

，下面是如何：

WebRequest WebRequest=new ServletWebRequest（request）反之亦然。来自WebRequest的HttpServletRequest
private Map<String, Object> getErrorAttributes(HttpServletRequest request, WebRequest webRequest,
                                               boolean includeStackTrace) {

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

}
