我正在尝试使用apache camel的简单弹簧启动应用程序。我有两个伪骆驼处理器，它们的sysout方法中有process()个。我有一个路由构建器，一个接一个地调用这些处理器。问题是我的springboot应用程序关闭太快，迫使camel上下文关闭，而不让处理器在控制台上执行和输出任何内容。
简单代码如下所示
MyProcessor1.java
import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.springframework.stereotype.Component;
@Component
public class MyProcessor1 implements Processor
{
public void process(Exchange exchange) throws Exception {
System.out.println("Inside my processor 1");
}
}
MyProcessor2.java
import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.springframework.stereotype.Component;
@Component
public class MyProcessor2 implements Processor
{
public void process(Exchange exchange) throws Exception {
System.out.println("Inside my processor 2");
}
}
MyRouteBuilder.java
import org.apache.camel.builder.RouteBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.digitate.ignio.smarttriggers.processors.MyProcessor1;
import com.digitate.ignio.smarttriggers.processors.MyProcessor2;
@Component
public class MyRouteBuilder extends RouteBuilder
{
@Autowired
MyProcessor1 myProcessor1;
@Autowired
MyProcessor2 myProcessor2;
public MyRouteBuilder(){}
@Override
public void configure() throws Exception {
System.out.println("Inside route builder");
from("file:C:\\Mahesh\\delete\\camelsource")
.process(myProcessor1)
.process(myProcessor2);
}
}
Application.java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) throws InterruptedException {
SpringApplication.run(Application.class, args);
}
}

当我在Thread.sleep(10000);类的main()方法末尾添加Application时，它会正确地让处理器运行并将相应的行打印到输出。
我知道这一点（springboot应用程序退出而不让处理器运行）是正确/预期的行为，但我想知道如果有任何方法可以让spring引导应用程序等到camel处理器完成执行。
