springboot 使用传统方式部署

spring boot默认创建出来的应用程序是内嵌web容器的,直接运行jar文件就可以的,但通常我们也需要将程序部署到tomcat中,这需要做如下改进:

1.pom.xml修改

打包方式需要修改成war:<packaging>war</packaging>

spring-boot-starter-web的配置中需要排除tomcat

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<artifactId>log4j-over-slf4j</artifactId>
<groupId>org.slf4j</groupId>
</exclusion>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>

同时为了应用能够正常编译,还需要加上tomcat的引用:

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>

2.重写SpringBootServletInitializer类中的configure方法

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {
 
 
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
 
 
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
