我遇到以下错误：

线程“主”中的异常java.lang.IllegalArgumentException：无法实例化接口org.springframework.context.ApplicationContextInitializer：org.springframework.boot.autoconfigure.SharedMetadataReaderFactoryContextInitializer位于org.springframework.boot.SpringApplication.createSpringFactoriesInstances（SpringApplication.java:414） org.springframework.boot.SpringApplication.getSpringFactoriesInstances（SpringApplication.java:385）上的org.springframework.boot.SpringApplication.getSpringFactoriesInstances（SpringApplication.java:394）org.springframework.boot.SpringApplication.initialize（SpringApplication.java:261）在org.springframework.boot.SpringApplication。（SpringApplication.java:237）在org.springframework.boot.SpringApplication.run（SpringApplication.java:1191）在org。springframework.boot.SpringApplication.run（SpringApplication.java:1180）

我的主要方法是

package proj1;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;

@SpringBootApplication
public class WebApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(WebApplication.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(WebApplication.class, args);
    }
}

我的pom.xml是
