springboot项目打成war包后就不能运行？

Question

异常描述 我的开发环境如下 框架：springboot，mybatis …… 工具：eclipse 数据库：MySQL 在开发工程中，使用启动类启动能够正常启动并测试。问题出在，我将项目打成war包，整个项目不能启动。 我在打包的时候做了如下操作：1 1.修改启动类 将启动类继承了SpringBootServletInitializer，并且重写了configure方法。 @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { // 注意这里要指向原先用main方法执行的Application启动类 return builder.sources(Application.class); } 2.修改依赖 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!-- 移除嵌入式tomcat插件 --> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency> <!-- 添加servlet-api的依赖 --> <dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-servlet-api</artifactId> <version>8.0.36</version> <scope>provided</scope> </dependency> 3.修改打包方式 <packaging>war</packaging> 4.maven-install打包 打包完成后，在tomcat-8.0.46中执行，出现以下错误提示 13-Sep-2017 09:49:34.794 严重 [localhost-startStop-1] org.apache.catalina.core.StandardContext.startInternal One or more Filters failed to start.

Answer 1

Application类要继承SpringBootServletInitializer。
