java - Spring XML 中的 Apache Camel 路由定义并使用 SpringBoot 运行

Question

我已经在 2 个 XML 文件中定义了 Camel 路由，并且想使用 Spring Boot 组件运行该应用程序。

主要代码如下:

Object[] sources = {
    "META-INF/spring/propertiesContext.xml",
    "META-INF/spring/concurrent-route-context.xml"
};
ApplicationContext applicationContext = new SpringApplication(sources).run(args);
CamelSpringBootApplicationController applicationController = applicationContext
    .getBean(CamelSpringBootApplicationController.class);
    applicationController.blockMainThread();

但是，我在启动过程中遇到以下错误

2015-08-19 14:54:04.203 ERROR 13812 --- [           main] o.s.boot.SpringApplication               : Application startup failed

如果我使用“spring-boot-starter”而不是“spring-boot-starter-web”更新我的 pom.xml，我会遇到另一个异常

如果我配置错误，有人可以提出建议吗？

我不知道您是否已找到解决方案，但请在您的应用程序类中尝试一下:

@Configuration
@EnableAutoConfiguration
public class TestSpringBootApplication
{
    public static void main(String... args)
    {
        (new SpringApplication("META-INF/spring/propertiesContext.xml",
                               "META-INF/spring/concurrent-route-context.xml")).run(args);
    }
}
