AHAS整合问题

大目老师好，我在整合ahas的时候遇到了问题，引入了ahas依赖后项目启动报错。

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
        <exclusions>
            <exclusion>
                <groupId>com.alibaba.csp</groupId>
                <artifactId>sentinel-transport-simple-http</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>com.alibaba.csp</groupId>
        <artifactId>spring-boot-starter-ahas-sentinel-client</artifactId>
        <version>1.10.1</version>
    </dependency>

报错日志如下：

APPLICATION FAILED TO START

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

com.alibaba.csp.ahas.sentinel.SentinelAnnotationAutoConfiguration.sentinelResourceAspect(SentinelAnnotationAutoConfiguration.java:44)

The following method did not exist:

com.alibaba.csp.sentinel.annotation.aspectj.SentinelResourceAspect.<init>(Lcom/alibaba/csp/sentinel/annotation/aspectj/SentinelAnnotationGlobalFallback;)V

The method’s class, com.alibaba.csp.sentinel.annotation.aspectj.SentinelResourceAspect, is available from the following locations:

jar:file:/G:/gradle-repository/com/alibaba/csp/sentinel-annotation-aspectj/1.5.2/sentinel-annotation-aspectj-1.5.2.jar!/com/alibaba/csp/sentinel/annotation/aspectj/SentinelResourceAspect.class
jar:file:/G:/gradle-repository/com/alibaba/csp/ahas-sentinel-client/1.10.1/ahas-sentinel-client-1.10.1.jar!/com/alibaba/csp/sentinel/annotation/aspectj/SentinelResourceAspect.class

It was loaded from the following location:

file:/G:/gradle-repository/com/alibaba/csp/sentinel-annotation-aspectj/1.5.2/sentinel-annotation-aspectj-1.5.2.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of com.alibaba.csp.sentinel.annotation.aspectj.SentinelResourceAspect

问题的原因：

sentinel-annotation-aspectj 和 ahas-sentinel-client 这两个jar包中都存在SentinelResourceAspect这个类

参考Ahas文档：https://help.aliyun.com/document_detail/110599.htm

在新版本的Ahas中，可以直接把<artifactId>spring-cloud-starter-alibaba-sentinel</artifactId> 删除试试。

谢谢老师，已解决，当初有这个删除依赖困扰是因为担心sentinel整合restTemplate问题，测试发现整合了AHAS不用再去restTemplate使用@SentinelRestTemplate整合了。
