springboot 项目打war包

修改主类，参照以下格式

EducationErverApplication.class

@SpringBootApplication
// war 包启动类
public class EducationErverApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(EducationErverApplication.class, args);
    }
    
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(EducationErverApplication.class);
    }
}
