一、导入依赖
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="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</> groupId>org.springframeworkartifactId>gs-actuator-serviceversion>0.1.0parent> >org.springframework.boot>spring-boot-starter-parent>1.5.8.RELEASEdependenciesdependency> >spring-boot-starter-web>spring-boot-starter-actuator>spring-boot-starter-testscope>testpropertiesjava.version>1.8java.versionbuildpluginsplugin> >spring-boot-maven-plugin> project>
二、构建实体
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;
}
}
三、编写Controller
package hello; import java.util.concurrent.atomic.AtomicLong; org.springframework.stereotype.Controller; org.springframework.web.bind.annotation.GetMapping; org.springframework.web.bind.annotation.RequestParam; org.springframework.web.bind.annotation.ResponseBody; @Controller public class HelloWorldController { private static final String template = "Hello,%s!"; final AtomicLong counter = new AtomicLong(); @GetMapping("/hello-world") @ResponseBody public Greeting sayHello(@RequestParam(name="name",required=false,defaultValue="Stranger") String name) { return Greeting(counter.incrementAndGet(),String.format(template,name)); } }
四、编写配置文件
server.port: 9000
management.server.port: 9001
management.server.address: 127.0.0.1
五、编写启动类
org.springframework.boot.SpringApplication; org.springframework.boot.autoconfigure.SpringBootApplication; /** * 使用Spring Boot Actuator构建RESTful Web服务 * */ @SpringBootApplication HelloWorldApplication { void main(String[] args) { SpringApplication.run(HelloWorldApplication.,args); } }
六、编写测试类
