我有一个Spring Boot应用程序，该应用程序可以在嵌入式tomcat容器中正常运行。但我希望将其部署在外部tomcat服务器上。因此，我遵循了一些在线教程并进行了更改，以使应用程序可与外部容器一起使用。
看起来像是tomcat部署了它，但是catalina.2018-06-28.log（严重警告）和localhost.2018-06-28.log（2 Spring WebApplicationInitializers）文件的输出有些奇怪，我不确定这意味着，如果那是问题。另外，当我从log4j2插件检查我的输出文件时，文件已创建，但为空。
不确定我想念的是什么。它不给我任何输出，也不起作用。如果我删除为使其与外部tomcat一起工作而添加的多余代码，它将与嵌入式tomcat一起工作。
下面是我的主要Java文件：
package com.consumer;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.ApplicationContext;
import com.consumer.config.KafkaConfig;
import com.consumer.services.KafkaConnector;
@SpringBootApplication
@EnableConfigurationProperties(KafkaConfig.class)
public class KafkaBussOpsConsumer extends SpringBootServletInitializer {
private static final Logger logger = LogManager.getLogger(KafkaBussOpsConsumer.class);
public static void main(String[] args) {
logger.info("||||||||||||||||| Application Started");
ApplicationContext context = SpringApplication.run(KafkaBussOpsConsumer.class, args);
KafkaConnector kConnector = context.getBean(KafkaConnector.class);
logger.info("Application about to connecto kafka");
kConnector.connect();
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(KafkaBussOpsConsumer.class);
}
}
