springboot+springcloud集成seata项目，启动项目的时候报错

Question

springboot+springcloud集成seata项目，启动项目的时候报错，不知哪里出了问题：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'globalTransactionScanner' defined in class path resource [com/alibaba/cloud/seata/GlobalTransactionAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [io.seata.spring.annotation.GlobalTransactionScanner]: Factory method 'globalTransactionScanner' threw exception; nested exception is io.seata.common.exception.NotSupportYetException: not support register type: null

Answer 1

pom文件中的seata依赖问题，在seata1.0版本之后，依赖要这样引入：

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-seata</artifactId>
    <exclusions>
        <exclusion>
            <groupId>io.seata</groupId>
            <artifactId>seata-spring-boot-starter</artifactId>
        </exclusion>
    </exclusions>
</dependency>

<dependency>
    <groupId>io.seata</groupId>
    <artifactId>seata-spring-boot-starter</artifactId>
    <version>1.4.0</version>
</dependency>
