使用Spring Cloud Alibaba进行链路追踪,需要使用阿里巴巴开源的中间件——Nacos和Sentinel。
具体步骤如下:
1. 引入依赖
在pom.xml文件中,引入以下依赖:
```xml
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-seata</artifactId>
</dependency>
```
2. 配置Nacos
在application.yml文件中,添加以下配置:
```yaml
spring:
cloud:
nacos:
discovery:
server-addr: ${NACOS_SERVER_ADDR:localhost:8848}
sentinel:
transport:
dashboard: localhost:8080
port: 8719
```
3. 配置Sentinel
在application.yml文件中,添加以下配置:
```yaml
spring:
cloud:
sentinel:
transport:
dashboard: localhost:8080
port: 8719
```
4. 配置链路追踪
在启动类中添加@EnableZipkinServer注解,激活Zipkin Server:
```java
@SpringBootApplication
@EnableZipkinServer
public class ZipkinServerApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinServerApplication.class, args);
}
}
```
5. 配置Sleuth
在服务中,需要使用Spring Cloud Sleuth进行链路追踪。在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-sleuth</artifactId>
</dependency>
```
然后在application.yml文件中配置:
```yaml
spring:
sleuth:
sampler:
probability: 1.0
```
以上就是使用Spring Cloud Alibaba进行链路追踪的步骤。总的来说,需要配置Nacos、Sentinel、Zipkin Server和Sleuth,以保证链路追踪的正常运行。
