Spring Cloud：Sleuth（七）

Spring Cloud Sleuth 整合

引入Maven依赖

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-sleuth</artifactId> </dependency> 

日志发生的变化

当应用ClassPath下存在org.springfreamwork.cloud:spring-cloud-starter-sleuth的时候，日志会发生调整。

激活

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

 Zipkin整合

创建 Spring Cloud Zipkin服务器

增加Maven依赖

<!-- 服务器依赖 --> <dependency> <groupId>io.zipkin.java</groupId> <artifactId>zipkin-server</artifactId> <version>2.11.11</version> </dependency> <!-- 服务器ui控制器 --> <dependency> <groupId>io.zipkin.java</groupId> <artifactId>zipkin-autoconfigure-ui</artifactId> <version>2.11.11</version> </dependency> 

激活Zipkin服务器

@SpringBootApplication @EnableZipkinServer public class SpringCloudZipkinDemoApplication { public static void main(String[] args) { SpringApplication.run(SpringCloudZipkinDemoApplication.class, args); } } 

HTTP 收集 （HTTP调用）

简单整合spring-cloud-sleuth

增加Maven依赖

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-zipkin</artifactId> </dependency> 

Spring Cloud 服务整合

扫描二维码关注公众号，回复： 8679311 查看本文章

端口信息

• spring-cloud-zuul:7070
• person-client:8080
• person-service:9090
• Eureka Server:12345
• ZipKin Server:23456
• Config Server:10001

服务启动顺序

1. zipkin Server
2. Eureka Server
3. spring-cloud-config-server
4. person-server
5. person-client
6. spring-cloud-zuul
7. spring-cloud-sleuth

spring-cloud-sleuth-demo改造

增加Eureka客户端依赖

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> 

配置调整

spring.application.name = spring-cloud-sleuth server.port = 6060 spring.zipkin.base-url=http://localhost:23456/ eureka.client.serviceUrl.defaultZone=http://localhost:12345/eureka 

调整代码链接：spring-cloud-zuul

完整调用链路

spring-cloud-sleuth → spring-cloud-zuul → person-client → person-service

@RestController

public class TestLoggerController {

final static Logger LOGGER = LoggerFactory.getLogger(TestLoggerController.class);

@Autowired

@Qualifier("restTemplate")

private RestTemplate restTemplate;

@GetMapping("/send")

public void send() {

LOGGER.info(" 欢迎欢迎！");

}

@GetMapping("/to/zuul/pseron-clint/findall")

public Object findall() {

LOGGER.info("TestLoggerController#findall()");

return restTemplate.getForObject("http://spring-cloud-zuul/person-client/person/findall", Object.class);

}

}

spring-cloud-zuul上报Zipkin服务器

依赖

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-zipkin</artifactId> </dependency> 

配置

spring.zipkin.base-url=http://localhost:23456/

person-client上报Zipkin服务器

依赖

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-zipkin</artifactId> </dependency> 

配置

spring.zipkin.base-url=http://localhost:23456/

person-service上报Zipkin服务器

依赖

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-zipkin</artifactId> </dependency> 

配置

spring.zipkin.base-url=http://localhost:23456/

Spring Cloud Stream 收集消息（消息）

调整spring-cloud-zipkin-server 通过Steam来收集

增加Maven依赖

<dependency><dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-sleuth-zipkin-stream</artifactId> </dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-stream-binder-kafka</artifactId> </dependency> 

激活Zipkin Stream

@SpringBootApplication //@EnableZipkinServer @EnableZipkinStreamServer public class SpringCloudZipkinDemoApplication { public static void main(String[] args) { SpringApplication.run(SpringCloudZipkinDemoApplication.class, args); } } 

调整spring-cloud-zuul

增加依赖

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-sleuth-stream</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-stream-binder-kafka</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-sleuth</artifactId> </dependency> 

注释HTTP上报URL

##日志上报

##spring.zipkin.base-url=http://localhost:23456/
