springboot配置全局事务

1、Pom依赖

 <!-- aop依赖 -->
<dependency>
     <groupId>org.aspectj</groupId>
     <artifactId>aspectjweaver</artifactId>
     <version>1.8.9</version>
</dependency>

2、config配置类

package demo.demobase.config;
 
import org.aspectj.lang.annotation.Aspect;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.aop.Advisor;
import org.springframework.aop.aspectj.AspectJExpressionPointcut;
import org.springframework.aop.support.DefaultPointcutAdvisor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.TransactionDefinition;
import org.springframework.transaction.interceptor.*;
 
import java.util.Collections;
import java.util.HashMap;
import java.util.Map;

    }
