Difference Between Spring Boot Starter Web and Spring Boot Starter Tomcat
Last Updated : 11 Mar, 2022
Spring Boot is built on the top of the spring and contains all the features of spring. And is becoming a favorite of developers these days because of its rapid production-ready environment which enables the developers to directly focus on the logic instead of struggling with the configuration and setup. Spring Boot is a microservice-based framework and making a production-ready application in it takes very little time. Following are some of the features of Spring Boot:
- It allows avoiding heavy configuration of XML which is present in spring
- It provides easy maintenance and creation of REST endpoints
- It includes embedded Tomcat-server
- Deployment is very easy, war and jar files can be easily deployed in the tomcat server
Spring Boot Starter Web
It is mainly used for building web applications that include RESTful applications using Spring MVC. It uses Tomcat as the default embedded container. It has two important features:
- It is compatible with web development.
- It can be auto-configured.
We need to add the following dependency in the pom.xml file for Spring Boot Starter Web:
XML <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>2.2.2.RELEASE</version> </dependency>
It uses Spring MVC, REST, and Tomcat as a default embedded server. The single spring-boot-starter-web dependency can pull in all dependencies related to web development. It also reduces the count of build dependency. The spring-boot-starter-web mainly depends on the following:
- org.springframework.boot:spring-boot-starter
- org.springframework.boot:spring-boot-starter-tomcat
- org.springframework.boot:spring-boot-starter-validation
- com.fasterxml.jackson.core:jackson-databind
- org.springframework:spring-web
- org.springframework:spring-webmvc
By default, the spring-boot-starter-web contains the below tomcat server dependency given:
XML <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <version>2.0.0.RELEASE</version> <scope>compile</scope> </dependency>
The spring-boot-starter-web auto-configures the below things required for the web development:
- Dispatcher Servlet
- Error Page
- Embedded servlet container
- Web JARs for managing the static dependencies
Spring Boot also supports Jetty Server and Undertow Server. They are embedded web servers. We can also exclude spring-boot-starter-tomcat from spring-boot-starter-web as follows:
XML <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency>
Spring Boot Starter Tomcat
While the spring-boot-starter-tomcat has everything related to the Tomcat server. It has
It has the below dependencies
XML <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-core</artifactId> <version>8.5.23</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-el</artifactId> <version>8.5.23</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-websocket</artifactId> <version>8.5.23</version> <scope>compile</scope> </dependency>
