SpringCloud：自定义skywalking链路追踪

一、添加依赖：

        <dependency>
            <groupId>org.apache.skywalking</groupId>
            <artifactId>apm-toolkit-logback-1.x</artifactId>
            <version>8.7.0</version>
        </dependency>

        <dependency>
            <groupId>org.apache.skywalking</groupId>
            <artifactId>apm-toolkit-trace</artifactId>
            <version>8.7.0</version>
        </dependency>

二、在普通业务方法添加@Trace注解：

    @Trace
    public String myBusiness(){
        return "my business";
    }

三、在skywalking UI界面可以看到普通业务方法：

可以通过@Tag注解来在skywalking里显示调用的参数和返回值

@Trace
@Tags({@Tag(key = "param", value = "arg[0]"),
       @Tag(key = "result", value = "returnedObj")})
public int get(Integer id) {
    return id;
}
