整合Spring Cloud Sleuth

一新建项目microservice-simple-provider-user-trace

二为项目添加以下依赖spring-cloud-starter-sleuth

  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
      <groupId>com.h2database</groupId>
      <artifactId>h2</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-sleuth</artifactId>
    </dependency>
  </dependencies>

三修改application.yml

server:
  port: 8000
spring:
  jpa:
    generate-ddl: false
    show-sql: true
    hibernate:
      ddl-auto: none
  datasource:                           # 指定数据源
    platform: h2                        # 指定数据源类型
    schema: classpath:schema.sql        # 指定h2数据库的建表脚本
    data: classpath:data.sql            # 指定h2数据库的数据脚本
  application:
    name: microservice-provider-user
logging:
  level:
    root: INFO
    org.springframework.cloud.sleuth: DEBUG
    # org.springframework.web.servlet.DispatcherServlet: DEBUG

这样就整合好Sleuth了。

用同样的方法新建一个项目microservice-simple-consumer-movie-trace

四测试

1 启动microservice-simple-provider-user-trace

2 访问http://localhost:8000/1,控制台会输出类似如下的日志：

3 启动项目microservice-simple-consumer-movie-trace

4 访问 http://localhost:8010/user/1,会发现两个项目都有日志。
