Use Maven to build a spring boot2.0 project under MyEclipse

Now it's time to build the Spring boot framework and implement a HelloWorld project to get the program up and running.

First, introduced in the Pom.xml spring-boot-start-parent,spring official called stater Poms, it can provide dependency management, that is, rely on management, In the future, when declaring other dependency, no version is needed.

<Parent>    <groupId>Org.springframework.boot</groupId>    <Artifactid>Spring-boot-starter-parent</Artifactid>    <version>2.0.0.RELEASE</version></Parent>

Second, the need to introduce spring-boot-starter-web,spring official explanation in Pom.xml Spring-boot-start-web contains features of web development such as spring WEBMVC and Tomcat.

<Dependencies>    <Dependency>        <groupId>Org.springframework.boot</groupId>        <Artifactid>Spring-boot-starter-web</Artifactid>    </Dependency></Dependencies>

Third, if we want to direct main to start spring, then the following plugin must be added, otherwise it will not start. This configuration is not required if you are using Maven's spring-boot:run.

<Plugins>    <plugin>        <groupId>Org.springframework.boot</groupId>        <Artifactid>Spring-boot-maven-plugin</Artifactid>    </plugin></Plugins>

Four, start writing the program, we need a startup class, and then in the launch class declaration let spring boot automatically give us the configuration spring needs, such as: @SpringBootApplication, in order to get the program to run quickly, Let's simply write an example of a browser accessing the word Hello World:

 PackageHello;Importorg.springframework.boot.*;ImportOrg.springframework.boot.autoconfigure.*;ImportOrg.springframework.stereotype.*;Importorg.springframework.web.bind.annotation.*; @Controller @enableautoconfiguration Public classSamplecontroller {@RequestMapping ("Home") @ResponseBody String Home () {return"Hello world!"; }     Public Static voidMain (string[] args)throwsException {springapplication.run (samplecontroller.class, args); }}

Where @enableautoconfiguration declares that spring boot automatically makes the necessary configuration for the program, equivalent to using @configuration,@ with default properties Enableautoconfiguration and @componentscan.

@RestController return data from a JSON string, you can write a restful interface directly.

Five, running our application, especially simple: Right-click Run as--Java application. Then open the browser input address: Http://127.0.0.1:8080/home can see Hello world!.

Vi. Complete Pom.xml file

<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/maven-v4_0_0.xsd">  <modelversion>4.0.0</modelversion>  <groupId>Com.zst</groupId>  <Artifactid>Mymaven</Artifactid>  <Packaging>War</Packaging>  <version>0.0.1-snapshot</version>  <name>Mymaven Maven Webapp</name>  <URL>http://maven.apache.org</URL>  <Parent>    <groupId>Org.springframework.boot</groupId>    <Artifactid>Spring-boot-starter-parent</Artifactid>    <version>2.0.0.RELEASE</version>  </Parent>  <Dependencies>    <Dependency>      <groupId>Junit</groupId>      <Artifactid>Junit</Artifactid>      <version>3.8.1</version>      <Scope>Test</Scope>    </Dependency>    <Dependency>        <groupId>Org.springframework.boot</groupId>        <Artifactid>Spring-boot-starter-web</Artifactid>    </Dependency>  </Dependencies>  <Build>    <Finalname>Mymaven</Finalname>  </Build></Project>

To some, our Spring boot project has been completed and the HelloWorld project has been successfully run.
