Configuring Servers With Spring boot

Consider you are using tomcat, springboot by default uses tomcat 7, if you want to change a version to tomcat 8, please add the below code in pom.xml

1. <properties>
2. <tomcat.version>8.0</tomcat.version>
3. </properties>

If you want to change server, from tomcat to jetty server the add below code

1. <dependencies>
2. <dependency>
3. <groupId>org.springframework.boot</groupId>
4. <artifactId>spring-boot-starter-web</artifactId>
5. <exclusions>
6. <exclusion>
7. <groupId>org.springframework.boot</groupId>
8. <artifactId>spring-boot-starter-tomcat</artifactId>
9. </exclusion>
10. </exclusions>
11. </dependency>
12. <dependency>
13. <groupId>org.springframework.boot</groupId>
14. <artifactId>spring-boot-starter-jetty</artifactId>
15. </dependency>
16. <dependency>
17. <groupId>org.springframework.boot</groupId>
18. <artifactId>spring-boot-starter-test</artifactId>
19. <scope>test</scope>
20. </dependency>
21. </dependencies>

exclude tomcat, and add new dependency w.r.t jetty server.

if you want to change port, then add below code in application.properties

1. server.port=8090

if you give server.port=0, then it will assign unused port number by default.

How to deploy spring-boot in other tomcat server.

1. give a result as war file from pom.xml
2. deploy the war in webapps of another server.

If you want to deploy your application on application server like Jboss====
Just change pom.xml

1. <parent>
2. <groupId>org.springframework.boot</groupId>
3. <artifactId>spring-boot-starter-parent</artifactId>
4. <version>1.2.7.RELEASE</version>
5. </parent>
6. <dependencies>
7. <dependency>
8. <groupId>org.springframework.boot</groupId>
9. <artifactId>spring-boot-starter-web</artifactId>
10. <exclusions>
11. <exclusion>
12. <groupId>org.springframework.boot</groupId>
13. <artifactId>spring-boot-starter-tomcat</artifactId>
14. </exclusion>
15. </exclusions>
16. </dependency>
17. <dependency>
18. <groupId>javax.servlet</groupId>
19. <artifactId>servlet-api</artifactId>
20. <version>2.5</version>
21. <scope>provided</scope>
22. </dependency>
23. </dependencies>
24. <build>
25. <finalName>SpringBootBasic</finalName>
26. <plugins>
27. <plugin>
28. <groupId>org.springframework.boot</groupId>
29. <artifactId>spring-boot-maven-plugin</artifactId>
30. </plugin>
31. </plugins>
32. </build>
33. </project>

and make sure, your SpringApplicationExample.java extends SpringBootServletIntializer

1. package younus.attari;
2. import org.springframework.boot.SpringApplication;
3. import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
4. import org.springframework.boot.autoconfigure.SpringBootApplication;
5. import org.springframework.boot.builder.SpringApplicationBuilder;
6. import org.springframework.boot.context.web.SpringBootServletInitializer;
7. import org.springframework.context.ApplicationContext;
8. import org.springframework.context.annotation.ComponentScan;
9. @SpringBootApplication
10. @ComponentScan("younus.attari")
11. @EnableAutoConfiguration
12. public class SpringApplicationExample extends SpringBootServletInitializer {
13. public static void main(String[] args) {
14. SpringApplication.run(applicationClass, args);
15. }
16. @Override
17. protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
18. return application.sources(applicationClass);
19. }
20. private static Class<SpringApplicationExample> applicationClass = SpringApplicationExample.class;
21. }
