prepare中缺少对静态文件配置的说明

你的意思是指南里面的没有说明 microservice.yaml 中需要正确配置静态页面的路径吗？ 即 修改如下配置项:

gateway.webroot: /code/servicecomb-fence/samples/EdgeService/src/main/resources

[lyflyy]

能否告知gateway.webroot 到底指向哪

[liubao68]

即静态页面相关的文件所在的目录，比如： servicecomb-fence/samples/EdgeService/src/main/resources/ui, 可以查看 microservice.yaml和StaticWebpageDispatcher

[lyflyy]

在项目中pom文件的配置是这样的

<dependencies>
        <dependency>
            <groupId>org.apache.servicecomb</groupId>
            <artifactId>java-chassis-spring-boot-starter-servlet</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.servicecomb</groupId>
            <artifactId>edge-core</artifactId>
        </dependency>
    </dependencies>

配置文件中没有去声明[gateway.webroot]

请求地址：http://localhost:9090/ui/login.html

不知道gateway.webroot需要怎么设置才能正常访问到静态资源，示例项目直接启动也是有这个错误，bmi、porter都是这个异常

[liubao68]

配置项在 microservice.yaml 或者 application.yml 里面

gateway:
  webroot: /code/servicecomb-samples/porter_lightweight/gateway-service/src/main/resources

sample里面的配置是 windows 配置。 表示当前磁盘，比如 D。

[lyflyy]

不如我这样问您，mac系统 启动
gateway.webroot应该配置为什么？
相对路径的根目录是static吗，还是要配置绝对路径，绝对路径要抛

root cannot start with / 

异常，相对路径
抛

Request has already been read

不如您直接告诉我mac下应该怎么配置吧

[liubao68]

mac 或者 linux 配置的是相对路径。 如果你已经尝试，并且还是报错， 可以试着调试下代码。看看为什么没有查找到页面文件，具体调试的类就是下面代码演示的 StaticHandler的handle方法。

@Override
  public void init(Router router) {
    String regex = "/ui/(.*)";
    StaticHandler webpageHandler = StaticHandler.create();
    webpageHandler.setWebRoot(WEB_ROOT);
    LOGGER.info("server static web page for WEB_ROOT={}", WEB_ROOT);
    router.routeWithRegex(regex).failureHandler((context) -> {
      LOGGER.error("", context.failure());
    }).handler(webpageHandler);
  }
