Springboot全局事务配置：XML配置和java类配置

第一种方式：XML配置；

首先要在启动类配置引入注解：

 然后配置XML:

 注：切入点一定要和自己项目中的目录结构对应，execution(* com.esl.ce.*.*.service..*.*(..))，.*代表一层目录。

 

第二种方式：java类配置事务

package com.esl.ce.web.common.util;

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;
