注解加载服务配置，部分服务正常部分事务失效，Dubbo代理类跳过了Spring CGLib的代理

kisChang commented 7 years ago

测试版本：(注：2.8.4的版本一样存在)

<dubbo.version>2.5.5</dubbo.version>
其他依赖版本：
<spring.version>4.3.10.RELEASE</spring.version>
<aspectj.version>1.7.4</aspectj.version>
<zookeeper.version>3.4.6</zookeeper.version>

问题简述：同样写法下，用注解配置的服务，部分类会走SpringCGLib代理，而部分却跳过了代理，导致事务失效。我认真比对了所有的写法，都一模一样，却出现了两种效果

备用解决方案：出问题的类改用xml配置，一切正常，问题应该出在 Dubbo的注解扫描

项目说明：使用了DBUtils，如下配置事务

     <\!--事务管理器配置-->
     <bean id="dataSourceProxy" class="org.springframework.jdbc.datasource.TransactionAwareDataSourceProxy">
         <constructor-arg name="targetDataSource" ref="ds"/>
     </bean>
     <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSourceProxy"/>
    <property name="nestedTransactionAllowed" value="true"/>
    </bean>
    <\!--Spring JDBC和DBUtils-->
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <constructor-arg name="dataSource" ref="dataSourceProxy"/>
    </bean>
    <bean id="queryRunner" class="org.apache.commons.dbutils.QueryRunner">
    <constructor-arg name="ds" ref="dataSourceProxy"/>
    </bean>
    <\!--事务注解支持-->
    <tx:annotation-driven transaction-manager="txManager"
                        proxy-target-class="true"/>

问题信息重现：代码写法（简化中间内容）：

正常的如下：

public interface OrderCreateService {
    ...
}

@Service
@com.alibaba.dubbo.config.annotation.Service(version = "1.0.0", interfaceName = "com.temsoft.oms.order.service.OrderCreateService")
public class OrderCreateServiceImpl implements OrderCreateService {
    ...
}

同样写法，错误的如下：

public interface OrdersMngService {
    ...
}
@Service
@com.alibaba.dubbo.config.annotation.Service(version = "1.0.0", interfaceName = "com.temsoft.oms.order.service.OrdersMngService")
public class OrdersMngServiceImpl implements OrdersMngService {
    ...
}

Spring配置(spring 的扫描，我全部都用include-filter 和 use-default-filters="false"，确定没有扫描两次)：

<!--注解方式加载-->
<dubbo:annotation />
<!-- 扫描注解Bean -->
<context:component-scan base-package="com.temsoft.oms" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Service"/>
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Component"/>
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Repository"/>
</context:component-scan>

说明：在测试过程中发现，错误的类（OrdersMngService）在Jrebel重载时也会是重载的Spring CGLib代理的类，但是Dubbo调用的依旧跳过了该代理。

错误说明方式：服务端按简述方式编写，消费端直接调用，目标函数直接报异常，传出调用栈，栈信息如下：

halober commented 6 years ago

@service不要同时注解dubbo的和spring的。可以看示例项目https://gitee.com/lei0719/spring-boot-starter-dubbo-example

chickenlj commented 6 years ago

@halober 我觉得同时配置dubbo和spring的service注解应该是没有问题的。这里的问题或许出在BeanPostProcessor执行的顺序上

chickenlj commented 6 years ago

transactional和dubbo service注解一同dubbo service应该是无法正常暴露才对呀，奇怪你这里竟然成功暴露了(OrderCreateService)

halober commented 6 years ago

指定了 interfaceName 或者interfaceClass，是可以暴露的。

kisChang commented 6 years ago

@halober 不好意思最近比较忙刚测试了一下，改为只用Dubbo的注解，配置改为以下配置

问题依旧存在

halober commented 6 years ago

吧这一行去掉，，

dubbo自己有处理这个注解的扫描，具体看这个类，AnnotationBean

kisChang commented 6 years ago

去掉后还是一样。。。老神奇了，就那几个特定的服务类出问题，都不变这样，抽时间我把代码整理出来一份发到github吧，由于是公司的项目，所以我还得把实现代码去掉，时间会长一点

duqicauc commented 6 years ago

+1，最后是怎么解决的？

halober commented 6 years ago

看代码呗，是不是用错注解了？

@duqicauc 事务问题可能是其他地方配置的问题，可以按我测试的方式试一下看是不是这个问题，如果是，备用解决方法前面说过

@chickenlj 实在不好意思，最近太忙没时间处理，我正在弄公司项目，clone出一个可以放出来的版本，但是代码量挺多的，我尽快完成刚试了2.5.7 问题依旧存在，可能是spring BeanPostProcessor 执行过程中出的问题今天下班挺早的，我继续改改公司的项目代码:smile:

kisChang commented 6 years ago

@chickenlj 项目弄好了，https://github.com/kisChang/cztTest README有说明，我测试的版本2.5.7 有问题

wallaceyoung commented 6 years ago

@kisChang 出问题的类xml是怎么配置的，能贴出来吗？

k42jc commented 6 years ago

遇到同样的问题，某些Service事务一直失效，跟进去对比发现无事务的服务调用字节码处理直接略过了spring事务相关的aop。看到你的备用方案改成xml配置解决。给你点个赞！

看到有人在追问xml配置怎么加，我顺便贴一下(spring-boot)： doubb-provider.xml

<?xml version="1.0" encoding="UTF-8"?>

Which dubbo version do you use? I think this problem has been fixed in 2.5.9/2.6.0 or earlier version.

@chickenlj
1、2.5.9 解决了,需要增加包扫描，之前只使用了<dubbo:annotation 配置

2、但是 2.6.0 问题依旧存在打印日志如，发布的服务接口为SpringProxy ，之前的版本也有此问题，由于不想每次注解中指定接口名称，于是修改了如下： //修复代理类发布的服务接口为 SpringProxy Class clazz = bean.getClass(); if (org.springframework.aop.support.AopUtils.isAopProxy(bean)) { clazz = org.springframework.aop.support.AopUtils.getTargetClass(bean); } serviceConfig.setInterface(clazz.getInterfaces()[0]); [com.alibaba.dubbo.registry.integration.RegistryProtocol]- [DUBBO] subscribe url: provider://192.168.2.77:20880/org.springframework.aop.SpringProxy?anyhost=true&application=dubbo-rss-provider&category=configurators&check=false&default.delay=-1&default.retries=0&default.timeout=60000&delay=-1&dubbo=2.6.0&generic=false&interface=org.springframework.aop.SpringProxy&methods=*&pid=10752&revision=4.2.5.RELEASE&side=provider×tamp=1521424569991&version=1.0.0, override urls: [empty://192.168.2.77:20880/org.springframework.aop.SpringProxy?anyhost=true&application=dubbo-rss-provider&category=configurators&check=false&default.delay=-1&default.retries=0&default.timeout=60000&delay=-1&dubbo=2.6.0&generic=false&interface=org.springframework.aop.SpringProxy&methods=*&pid=10752&revision=4.2.5.RELEASE&side=provider×tamp=1521424569991&version=1.0.0], dubbo version: 2.6.0, current host: 127.0.0.1 [com.alibaba.dubbo.config.model.ApplicationModel]- [DUBBO] already register the provider service: org.springframework.aop.SpringProxy:1.0.0, dubbo version: 2.6.0, current host: 127.0.0.1

我也遇到了同样的问题，在com.alibaba.dubbo.config.spring.AnnotationBean 的204行serviceConfig.setRef(bean);设置ServiceBean 的ref时，部分服务会使用目标对象导致dubbo的服务有事务时没有被增强，改成 serviceConfig.setRef(applicationContext.getBean(beanName,clazz)); 即可
