Springboot Combat (10) building a RESTful Web service using Spring Boot Actuator

First, import dependency

<?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>Org.springframework</groupId>    <Artifactid>Gs-actuator-service</Artifactid>    <version>0.1.0</version>    <Parent>        <groupId>Org.springframework.boot</groupId>        <Artifactid>Spring-boot-starter-parent</Artifactid>        <version>1.5.8.RELEASE</version>    </Parent>    <Dependencies>        <Dependency>            <groupId>Org.springframework.boot</groupId>            <Artifactid>Spring-boot-starter-web</Artifactid>        </Dependency>        <Dependency>            <groupId>Org.springframework.boot</groupId>            <Artifactid>Spring-boot-starter-actuator</Artifactid>        </Dependency>        <Dependency>            <groupId>Org.springframework.boot</groupId>            <Artifactid>Spring-boot-starter-test</Artifactid>            <Scope>Test</Scope>        </Dependency>    </Dependencies>    <Properties>        <Java. Version>1.8</java.version>    </Properties>    <Build>        <Plugins>            <plugin>                <groupId>Org.springframework.boot</groupId>                <Artifactid>Spring-boot-maven-plugin</Artifactid>            </plugin>        </Plugins>    </Build></Project>

Ii. Building Entities

Package Hello;public class Greeting {    private final long id;    Private final String content;    Public greeting (Long ID, String content) {        this.id = ID;        this.content = content;    }    Public long GetId () {        return ID;    }    Public String getcontent () {        return content;    }}

III. Preparation of Controller

 PackageHello;ImportJava.util.concurrent.atomic.AtomicLong;ImportOrg.springframework.stereotype.Controller;Importorg.springframework.web.bind.annotation.GetMapping;ImportOrg.springframework.web.bind.annotation.RequestParam;Importorg.springframework.web.bind.annotation.ResponseBody; @Controller Public classHelloworldcontroller {Private Static FinalString template = "Hello,%s!"; Private FinalAtomiclong counter =NewAtomiclong (); @GetMapping ("/hello-world") @ResponseBody PublicGreeting SayHello (@RequestParam (name= "name", required=false, defaultvalue= "Stranger") (String name) {return NewGreeting (Counter.incrementandget (), String.Format (template, name)); }}

Iv. Writing configuration Files

server.port:9000management.server.port:9001management.server.address:127.0.0.1

V. Writing the Startup class

 PackageHello;Importorg.springframework.boot.SpringApplication;Importorg.springframework.boot.autoconfigure.SpringBootApplication;/*** Build restful Web services using Spring Boot actuator * */@SpringBootApplication Public classhelloworldapplication { Public Static voidMain (string[] args) {Springapplication.run (helloworldapplication.class, args); }}

Six, write test class
