我有一个Apache Camel v3.3项目，它可以作为独立的应用程序很好地工作，但我很难将其部署到Tomcat。

我得到的错误是：

我尝试过使用和不使用ContextLoaderListener；同样的错误也被抛出。

我的代码完全是@Annotated的，所以我没有apache-config或spring-config文件。

如何防止Tomcat中的启动程序尝试读取不存在的文件-我猜这就是[/<NONE>]的意思？-因为该文件不是必需的。

我的目标是在Tomcat中运行我的Camel应用程序，这样我就可以使用Hawtio控制台进行观察和管理。

我认为这个问题可能是由于缺少定义camel XMl文件位置的标记造成的。请查看官方指南here

此外，如果你想使用hawtio来监控camel，你甚至可以在jolokia的帮助下将其部署到Tomcat中。您需要传递JVM arg -javaagent:并在独立模式下运行hawtio。

我在这里找到了答案：https://www.baeldung.com/spring-boot-war-tomcat-deploy。

以下两个Spring依赖项是必需的：

代码语言：javascript
复制
<!--Spring boot dependencies to enable WEB and TOMCAT features -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

而且还需要一个web starter应用程序：

代码语言：javascript
复制
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

/**
 * See https://www.baeldung.com/spring-boot-war-tomcat-deploy
 */
@SpringBootApplication
public class WebApp extends SpringBootServletInitializer {
    
}

不需要配置-例如，不需要web.xml。

就是这样！它在第一次就能正常工作，之后就完美无缺了。
