開發環境使用jdk1.8.0_60，把springboot 項目打成war包后，

部署到apache-tomcat-7.0.68時報錯如下，換成apache-tomcat-8.0.9解決

另外springboot項目打成war包部署到tomcat時需要改變啟動方式，否則運行tomcat時war包只會解壓，但是加載不了

import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.builder.SpringApplicationBuilder;import org.springframework.boot.context.web.SpringBootServletInitializer;@SpringBootApplication  //- springboot項目,并配置掃描路徑@EnableAutoConfiguration //- springboot自動配置，這個注解可以根據你依賴的包自動生成相關配置public class StartApp extends SpringBootServletInitializer {  public static void main(String[] args) {    SpringApplication.run(StartApp.class, args);  }  /**   * 需要把web項目打成war包部署到外部tomcat運行時需要改變啟動方式   */  @Override  protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {    return builder.sources(StartApp.class);  }
