java - 使用驼峰路由提供静态文件

Question

我正在尝试在 Camel 路由中提供静态文件。

我的主类中的路由包含这段代码:

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");
  }

这个效果很好。当我点击网址:http://xxxx:8086/user/dist/index.html时，我的索引页面将呈现，并且网址显示为http://xxxx:8086网址栏中的/user/dist/。

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

This page should have been replaced by Swagger.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>

我的有效 POM 具有这种依赖性。那么我错过了什么？

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。为什么我需要在网址末尾明确写入 index.html ？

任何帮助/建议将不胜感激。

我制作了一个简单的 JUnit 测试用例来测试您基于 this blog post 的场景.

StaticProcessor 类的实现在哪里？我已经为这个场景实现了一些非常相似的东西(恕我直言):

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，并将输出消息设置为响应。请看一下整个test case .

我测试了以下网址:

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

请注意，我像您一样添加了 swagger 插件依赖项。

请告诉我这是否有帮助或指出 StaticProcessor 实现的位置，我可以用它进行测试并编辑我的答案。

干杯
