Springboot deploy the project to an external Tomcat

1. Remove Springboot dependent embedded Tomcat

 1 <dependency>
 2     <groupId>org.springframework.boot</groupId>
 3         <artifactId>spring-boot-starter-web</artifactId>
 4          <exclusions>
 5                 <!-- 去除内嵌tomcat -->
 6                 <exclusion>
 7                     <groupId>org.springframework.boot</groupId>
 8                     <artifactId>spring-boot-starter-tomcat</artifactId>
 9                 </exclusion>
10             </exclusions>
11 </dependency>        

2. The introduction of the dependent servlet

1 <!--添加servlet的依赖 -->
2         <dependency>
3             <groupId>javax.servlet</groupId>
4             <artifactId>javax.servlet-api</artifactId>
5             <scope>provided</scope>
6         </dependency>

3. introduced separately dependent Tomcat

1 <dependency>
2             <groupId>org.springframework.boot</groupId>
3             <artifactId>spring-boot-starter-tomcat</artifactId>
4             <scope>provided</scope>
5         </dependency>

4 is a packaging bag war

 <packaging>war</packaging> <dependencies> ... </dependencies> 

5. Let Springboot start class inheritance SpringBootServletInitializer, rewrite configure method

 1 @SpringBootApplication
 2 public class JobSpiderApplication extends SpringBootServletInitializer {
 3 
 4     public static void main(String[] args) {
 5         SpringApplication.run(JobSpiderApplication.class, args);
 6     }
 7 
 8     @Override
 9     protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
10         return builder.sources(this.getClass());
11     }
12 
13 }

6. Project Right -> Run As-> Maven clean after, Maven install, until the console output "BUILD SUCCESS", to target files in the project folder path find XXX-0.0.1-SNAPSHOT.war package, renamed brief written, copied to the file server Tomcat webapps directory folder.
