SpringBoot项目war包部署到tomcat无法访问404

需要添加一个servlet初始化类以支持传统的war包方式

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {
    
    
  @Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    
    
    return application.sources(TestApplication.class); // 主启动类的类名
  }
}
