spring-boot项目需要部署在外部容器中的时候,spring-boot导出的war包无法再外部容器(tomcat)中运行或运行报错。
为了解决这个问题,需要移除springBoot自带的tomcat容器。
具体解决方法如下:
1.pom.xml中
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!-- 排除内置容器,排除内置容器导出成war包可以让外部容器运行spring-boot项目--> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency> <!-- 增加servlet-api依赖 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> </dependency>
2.实现SpringBootServletInitializer接口
import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.support.SpringBootServletInitializer; public class Application extends SpringBootServletInitializer{ public static void main(String[] args) { SpringApplication.run(Application.class); } @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); } }
