使用骆驼路由提供静态文件 [英] Serving static files with camel routes
问题描述
我正在尝试在骆驼路由中提供静态文件.
I am trying to serve a static file in camel routes.
我的主类中的路由包含这段代码:
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");
}
这很好用.当我点击 url:http://xxxx:8086/user/dist/index.html 时，我的索引页面被呈现并且 url 显示为 http://xxxx:8086/user/dist/ 在网址栏中.
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)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:
这个页面应该已经被 Swagger 取代了.你有没有在您的应用程序的 pom.xml 中作为对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This page should have been replaced by Swagger.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>
我的有效 POM 中有这种依赖性.那么我错过了什么?
I have this dependency in my effective POM. So what am I missing?
我希望使用 http://clv035sl-8947d6:8888/user/dist 的任何 url 都应该将调用路由到 index.html.为什么我需要在 url 的末尾显式写 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
我基于 这篇博文.
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):
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，并将输出消息设置为响应.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.
Please note that I added the swagger plugin dependency just like you did.
让我知道这是否有帮助或指出 StaticProcessor 实现在哪里，我可以用它测试并编辑我的答案.
Let me know if that helps or point where the StaticProcessor implementation is that I may test with it and edit my answer.
