使用Tomcat的Spring Stream AggregateApplication

我正在尝试配置ServletInitializer以在带有WAR打包的tomcat主机中运行Spring Stream Aggreagate应用程序。父应用程序配置为... 

@SpringBootApplication
public class MyAggregateApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        AggregateApplication aggregateApp = new AggregateApplicationBuilder()
                .from(MySource.class)
                .via(MyProcessor.class)
                .to(LogSink.class).build();
        return application.sources(aggregateApp);
    }

    public static void main(String[] args) {
        new AggregateApplicationBuilder()
                .from(MySource.class)
                .via(MyProcessor.class)
                .to(LogSink.class)
                .run(args);
    }
}

这可以作为一个独立的jar运行，但是，当部署到Tomcat服务器时，ServletInitializer配置挂钩无法接受application.sources（aggregateApp）的configure方法返回，如错误所示......

尝试使用AppClass ...... 

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(MyAggregateApplication.class);
}

不希望将App配置为AggregateApplication，不会自动配置内部消息代理并导致此错误...

有关在ServletInitalizer中连接AggregateApplication或禁用binderRegistry bean忽略缺少的绑定器的任何建议吗？添加rabbitMQ或Kafka绑定器会导致处理器应用程序绑定到这些代理。

2 个答案:

答案 0 :(得分：1)

  

application.sources(aggregateApp)

以上似乎不是正确的做法，因为AggregateApplicationBuilder不是SpringApplicationBuilder的有效来源，因为您只能拥有Class的有效类型，{{1 }}，Package和Resource作为来源。

答案 1 :(得分：0)

我能够通过为聚合堆栈提供run（）方法来运行它，该方法返回ConfigurableApplicationContext，允许作为源。我还必须禁用带有web的web（false），因为嵌入式tomcat似乎仍然想要启动...
