导致这个问题的原因是alibaba的@Service注解和@Transactional冲突
解决办法
1、将@Service注解修改为spring提供的@Service
2、添加如下配置文件
applocationContext_dubbo.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.2.xsdhttp://code.alibabatech.com/schema/dubbohttp://code.alibabatech.com/schema/dubbo/dubbo.xsd"><!-- 声明需要暴露的服务接口 --><!-- <dubbo:service interface="com.huarui.cart.service.CartService" ref="CartServiceImpl" timeout="600000"/> --><!-- <dubbo:service interface="com.huarui.sso.service.TbUserService" ref="TbUserServiceImpl" timeout="600000"/> --><!-- <dubbo:service interface="com.huarui.search.service.SearchItemService" ref="SearchItemServiceImpl" timeout="600000"/> --><dubbo:service interface="com.test.service.UserService" ref="userServiceImpl" timeout="600000"/></beans>3、在入口程序添加如下注解，去扫描配置文件
