Spring Boot rapid Development Web project

When we used the spring framework before, we needed to add dependency dependencies to the Pom file, and then create a new spring-related XML file, often with fewer XML files. Then continue to use Tomcat or jetty as a container to run the project. Basically creating a new project every time is such a process, and we sometimes just want to quickly create a spring Web project to test something, or to save time.

Now we can do this quickly with spring boot.

1. We create a MAVEN project, the project name is Spring-boot-helloworld, and then modify the Pom.xml file:

<?XML version= "1.0" encoding= "UTF-8"?><Projectxmlns= "http://maven.apache.org/POM/4.0.0"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelversion>4.0.0</modelversion>    <groupId>Net.mingyang</groupId>    <Artifactid>Spring-boot-helloworld</Artifactid>    <version>0.0.1-snapshot</version>    <Packaging>Jar</Packaging>    <name>Spring-boot-helloworld</name>    <Description>Demo Project for Spring Boot</Description>    <Parent>        <groupId>Org.springframework.boot</groupId>        <Artifactid>Spring-boot-starter-parent</Artifactid>        <version>1.4.1.RELEASE</version>        <RelativePath/> <!--Lookup parent from repository -    </Parent>    <Properties>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>        <java.version>1.7</java.version>    </Properties>    <Dependencies>        <Dependency>            <groupId>Org.springframework.boot</groupId>            <Artifactid>Spring-boot-starter-web</Artifactid>        </Dependency>        <Dependency>            <groupId>Org.springframework.boot</groupId>            <Artifactid>Spring-boot-starter-test</Artifactid>            <Scope>Test</Scope>        </Dependency>    </Dependencies>    <Build>        <Plugins>            <plugin>                <groupId>Org.springframework.boot</groupId>                <Artifactid>Spring-boot-maven-plugin</Artifactid>            </plugin>        </Plugins>    </Build></Project>

2. Create a new controller to accept the processing of our request:

 PackageNet.mingyang.spring_boot_helloworld;Importorg.springframework.boot.SpringApplication;Importorg.springframework.boot.autoconfigure.SpringBootApplication;ImportOrg.springframework.stereotype.Controller;Importorg.springframework.web.bind.annotation.RequestMapping;ImportOrg.springframework.web.bind.annotation.RequestMethod;Importorg.springframework.web.bind.annotation.ResponseBody, @SpringBootApplication @controller Public classSimplecontroller {@RequestMapping (value= "/hello", method =requestmethod.get) @ResponseBody PublicString Hello () {return"Hello World"; }         Public Static voidMain (string[] args) {Springapplication.run (simplecontroller.class, args); }}

3. Execute the main () method in Simlecontroller:

  . ____          _            __ _ _ /\\/___ ' _ __ _ _ (_) _ __ _ \ \ \ (() \___ | ' _ | ' _| | ' _ \ _ ' | \ \ \  \\/  ___)| |_)| | | | | || (_| |  ) ) ) )  ' |____|. __|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/: : Spring Boot:: (v1.4.1.

View logs can be found by default Tomcat, port binding at 8080, Access: Http://localhost:8080/hello, you can see the output of our code words.

Isn't it simple?
