• 谷粒商城遇到的问题


    在做谷粒商城的时候,雷神把seata放到common包中,然后重启了订单和库存服务,别的服务没有重启,但是重启的时候就会报错了,

    因为他们的下面没有那2个配置文件。他应该只是处于演示,所以我就把seata的依赖提到那2个微服务中,发现启动报错

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSourceProxy' defined in class path resource [com/demo/consumer/config/DataSourceProxyConfig.class]: Initialization of bean failed; nested exception is io.seata.common.exception.ShouldNeverHappenException: Auto proxy of DataSource can't be enabled as you've created a DataSourceProxy bean.Please consider removing DataSourceProxy bean or disabling auto proxy of DataSource.

    我是这样引入的,然后先根据报错进行找问题,在github上找到:https://github.com/seata/seata/issues/2469

    给出这样的解决方法,但是我在common中是可以的,唯一不一样的就是有一段dependencyManagement,

    然后加入到2个服务就可以了。

        <dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>${spring-cloud.version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
                <dependency>
                    <groupId>com.alibaba.cloud</groupId>
                    <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                    <version>2.1.0.RELEASE</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>
    
    
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-seata</artifactId>
