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</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>

 

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;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HelloWorldController {

    private static final String template = "Hello, %s!";
    private final AtomicLong counter = new AtomicLong();

    @GetMapping("/hello-world")
    @ResponseBody
    public Greeting sayHello(@RequestParam(name="name", required=false, defaultValue="Stranger") String name) {
        return new 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

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
 * 使用Spring Boot Actuator构建RESTful Web服务
 *
 */
@SpringBootApplication
public class HelloWorldApplication {

    public static void main(String[] args) {
        SpringApplication.run(HelloWorldApplication.class, args);
    }

}

 

六、编写测试类

 */
package hello;

import java.util.Map;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.web.client.TestRestTemplate;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.test.context.TestPropertySource;
import org.springframework.test.context.junit4.SpringRunner;

import static org.assertj.core.api.BDDAssertions.then;

/**
 * Basic integration tests for service demo application.
 *
 * @author Dave Syer
 */
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@TestPropertySource(properties = {"management.port=0"})
public class HelloWorldApplicationTests {

    @org.springframework.boot.context.embedded.LocalServerPort
    private int port;

    @Value("${local.management.port}")
    private int mgt;

    @Autowired
    private TestRestTemplate testRestTemplate;

    @Test
    public void shouldReturn200WhenSendingRequestToController() throws Exception {
        @SuppressWarnings("rawtypes")
        ResponseEntity<Map> entity = this.testRestTemplate.getForEntity(
                "http://localhost:" + this.port + "/hello-world", Map.class);

        then(entity.getStatusCode()).isEqualTo(HttpStatus.OK);
    }

    @Test
    public void shouldReturn200WhenSendingRequestToManagementEndpoint() throws Exception {
        @SuppressWarnings("rawtypes")
        ResponseEntity<Map> entity = this.testRestTemplate.getForEntity(
                "http://localhost:" + this.mgt + "/actuator/info", Map.class);

        then(entity.getStatusCode()).isEqualTo(HttpStatus.OK);
    }

}
