使用骆驼路线提供静态文件 [英] Serving static files with camel routes

问题描述

我正在尝试在骆驼路线中提供静态文件.

I am trying to serve a static file in camel routes.

主类中的路由包含以下代码:

The routes in my main class contains this piece of code:

public final void configure() throws Exception {
    // declaring camel routes
    // match on uri prefix must be true when parameters are passed as part of the uri
    // for example, "http://localhost/hello/rick"
    // http.port is in local.properties file user-api

    from("jetty:http://0.0.0.0:{{http.port}}/user/dist/?matchOnUriPrefix=true")
      .process( new StaticProcessor( "help", "index.html", "dist"))
      .routeId( "static");

    from("jetty:http://0.0.0.0:{{http.port}}/user?matchOnUriPrefix=true")
    .to("cxfbean:userService");
  }

这很好.当我按下url:http://xxxx:8086/user/dist/index.html时，将显示我的索引页，并且该URL在URL栏中显示为http://xxxx:8086/user/dist/.

This works good. When I hit the url: http://xxxx:8086/user/dist/index.html, my index page is rendered and the url shows to behttp://xxxx:8086/user/dist/ in url bar.

但是当我重新加载页面(按F5键)时，URL变为:http://xxxx:8086/user/dist//，并且出现如下错误:

But when I reload the page (press F5), the url becomes: http://xxxx:8086/user/dist// and I get error like:

该页面应该已经被Swagger取代.你有吗 在您应用程序的pom.xml中作为以下内容的唯一参考 swagger-maven-plugin?

This page should have been replaced by Swagger. Do you have the following in your application's pom.xml as the only reference to the swagger-maven-plugin?

    <build>
        <plugins>
            <plugin>
                <groupId>com.github.kongchen</groupId>
                <artifactId>swagger-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>swagger</id>
                        <phase>compile</phase>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

我在有效的POM中具有这种依赖性.那我想念什么呢?

I have this dependency in my effective POM. So what am I missing?

我希望实现任何带有http://clv035sl-8947d6:8888/user/dist的URL都应将调用路由到index.html.为什么我需要在URL末尾明确写index.html?

I wish to achieve that any url with http://clv035sl-8947d6:8888/user/dist should route the call to index.html. Why I need to explictly write index.html at end of the url?

任何帮助/建议将不胜感激.

Any help/ suggestion will be appreciated.

推荐答案

我制作了一个简单的JUnit测试用例，用于基于

I made a simple JUnit Test case to test your scenario based on this blog post.

StaticProcessor类的实现在哪里?对于这种情况，我已经实现了一些非常相似的内容(IMHO):

Where are the implementation of the StaticProcessor class? I've implemented something for this scenario that is quite similar (IMHO):

public void configure() throws Exception {

    from("jetty:http://0.0.0.0:8080/user/dist?matchOnUriPrefix=true").process(new Processor() {

        public void process(Exchange exchange) throws Exception {
            Message in = exchange.getIn();

            String relativepath = in.getHeader(Exchange.HTTP_PATH, String.class);
            String requestPath = in.getHeader("CamelServletContextPath", String.class); //CamelServletContextPath

            if (relativepath.isEmpty() || relativepath.equals("/")) {
                relativepath = "index.html";
            }

            final String formattedPath = String.format("%s/%s", requestPath, relativepath);
            InputStream pathStream = this.getClass().getResourceAsStream(formattedPath);
            Path path = FileSystems.getDefault().getPath(this.getClass().getResource(formattedPath).getPath());

            Message out = exchange.getOut();
            try {
                out.setBody(IOUtils.toByteArray(pathStream));
                out.setHeader(Exchange.CONTENT_TYPE, Files.probeContentType(path));
            } catch (IOException e) {
                out.setBody(relativepath + " not found.");
                out.setHeader(Exchange.HTTP_RESPONSE_CODE, "404");
            }
        }
    }).routeId("static");
}

它从类路径中获取需要公开的资源，并将out消息设置为响应.请查看整个测试用例.

It takes from the classpath the resources that needed to be exposed and set the out message to the response. Please, take a look at the entire test case.

我已经测试了以下URL:

I've tested the following URLs:

• http://localhost:8080/user/dist/
• http://localhost:8080/user/dist
• http://localhost:8080/user/dist/index.html

• http://localhost:8080/user/dist/
• http://localhost:8080/user/dist
• http://localhost:8080/user/dist/index.html

请注意，就像您一样，我添加了swagger插件依赖项.

Please note that I added the swagger plugin dependency just like you did.

让我知道这对您有帮助还是指出StaticProcessor实现的目的，以便我可以对其进行测试并修改答案.

Let me know if that helps or point where the StaticProcessor implementation is that I may test with it and edit my answer.
