在启动春季引导+ Apache的骆驼HTTP组件崩溃：缺少EmbeddedServletContainerFactory豆 [英] Spring Boot + Apache Camel HTTP component crashes at start: missing EmbeddedServletContainerFactory bean
问题描述
只是把春天引导兜风，并决定在骆驼混合，因为我需要一些神秘的头在其他地区的客户我工作的工作。设置应用程序是罚款，直到我添加了骆驼HTTP组件到我的POM，然后我得到这个初始化上：
异常线程mainorg.springframework.context.ApplicationContextException：无法启动嵌入容器;嵌套的例外是org.springframework.context.ApplicationContextException：无法启动EmbeddedWebApplicationContext由于缺少EmbeddedServletContainerFactory豆。
我一直还没有得到从哪里开始寻找问题的第一个想法。我收集春天启动将查找类路径，并尝试丝东西了，所以那里的，从上或排序？
的东西正在采取行动阻止骆驼包的方式的完整的日志启动这个吉斯特
下面是我的主要aplication code：

的System.out.println（让我们检查由Spring提供引导豆：）;
的String [] = beanNames ctx.getBeanDefinitionNames（）;
Arrays.sort（beanNames）;
对于（字符串beanName：beanNames）{
的System.out.println（beanName）;
}

唯一的例外是告诉你，春天启动认为你想建立一个Web服务器，但是找不到类路径的正确依赖关系。对于你的情况最明显的原因是，你添加的HTTP依赖性包含的Servlet API的。我不明白为什么你需要一个客户端应用程序，但只有你会知道你是否需要与否。也许你可以排除了吗？
如果你需要Servlet的依赖关系，只是想明确地告诉你没有创建一个Web应用程序，您可以设置该属性启动 spring.main.web_environment = FALSE ，或者直接使用 SpringApplication （或 SpringApplicationBuilder ）API设置相同的标志。见<一href=\"https://github.com/spring-projects/spring-boot/blob/master/docs/howto.md#create-a-non-web-application\"相对=nofollow>这里的背景信息的文档。
Just taking Spring-Boot for a spin and decided to mix in Camel because I need some arcane Headers work in the rest client I am working on. Setting up the application was fine until I added the camel-http component to my POM, then I get this on init:
Exception in thread "main" org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.
I've havent got the first idea of where to start to look for the problem. I gather Spring Boot will look up the classpath and try to wire stuff up, so is there a way for the to block the Camel packages from being acted on or something of the sort?
Complete log of the start up in this Gist
Here's my main aplication code:
@ComponentScan
@EnableAutoConfiguration
public class Application {
private static ApplicationContext ctx;
public static void main(String[] args) throws Exception {
ctx = SpringApplication.run(Application.class, args);
//Right outta Spring 4 docs
System.out.println("Let's inspect the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
System.out.println(beanName);
}
//---
// FIXME: ugly hack to allow some POC woek while wait for proper Camel/Spring4 unit tests fix.
Application app = new Application();
app.executeTests();
}
/**
* Dev QOL - unit tests are broken for now, see:
* https://issues.apache.org/jira/browse/CAMEL-7074
* <p/>
* Waiting for fix (Too lay to checkout and build my own Camel)
*/
private void executeTests() throws Exception {
testAuth();
}
@Bean
DefaultCamelContext camelCtx() throws Exception {
DefaultCamelContext camel = new DefaultCamelContext();
camel.addRoutes(cryptsyRouteBuilder());
camel.start();
return camel;
}
@Bean
public CryptsyRouteBuilder cryptsyRouteBuilder() throws Exception{
CryptsyRouteBuilder bean = new CryptsyRouteBuilder();
bean.setCryptsy(cryptsy());
return bean;
}
@Bean
public Cryptsy cryptsy() throws IOException {
return new Cryptsy();
}
protected void testAuth() throws Exception {
ProducerTemplate producer = camelCtx().createProducerTemplate();
producer.requestBody("direct:start", "Why, hullo there", String.class);
}
}

The exception is telling you that Spring Boot thinks you want to build a web server, but can't find the right dependencies on the classpath. The most obvious reason for that in your case would be that the HTTP dependencies you added included Servlet APIs. I see no reason why you need that for a client app, but only you would know whether you need it or not. Maybe you can exclude it?
If you do need the Servlet dependencies and just want to explicitly tell Boot that you aren't creating a web application you can set the property spring.main.web_environment=false, or use the SpringApplication (or SpringApplicationBuilder) API directly to set the same flag. See docs here for background information.
