Caused by: java.lang.AbstractMethodError: com.alibaba.cloud.sentinel.feign.SentinelContractHolder...-优快云博客

本文档介绍了在SpringCloud项目中遇到的错误，通过将SpringCloud版本从Hoxton.SR1更新到Hoxton.SR3来解决Sentinel注入资源失败的问题，确保PaymentService的正常创建。

报错：

解决：

Spring Cloud版本问题~

我原来的版本：

 		<!--spring cloud Hoxton.SR1-->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.SR1</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

修改：

Hoxton.SR1 为 Hoxton.SR3

		<!--spring cloud Hoxton.SR3-->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.SR3</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
