我正在尝试在 Tomcat 服务器上设置 Spring Boot 应用程序,但遇到了问题。我不断收到以下错误:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

这是我的程序的主要类:

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@Slf4j
@SpringBootApplication
public class DataPowerSyncProcess extends SpringBootServletInitializer {

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

    public static void main(String... args){
        addCommonProperties(new SpringApplicationBuilder())
                .build().run(args);
    }

    private static SpringApplicationBuilder addCommonProperties(SpringApplicationBuilder applicationBuilder){
        return applicationBuilder.sources(DataPowerSyncProcess.class);
    }
}

我一直注意到的是,我之前所说的错误似乎发生在 SpringBootServletInitializer 类中的这一行之后:

WebApplicationContext rootAppContext = this.createRootApplicationContext(servletContext);

编辑:这是我的 POM 文件。
