Question

我的程序中有一个循环引用。我认为我的计划没有问题。它可以在windows上运行。当我把它放在linux上时，会导致异常。

以下是错误日志：

org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'customGroupDataManager': 
Requested bean is currently in creation: Is there an unresolvable circular reference?`

以下是我的代码：

<bean id="customUserDataManager" lazy-init="true" class="com.hand.hap.activiti.manager.CustomUserDataManager">
    <constructor-arg ref="processEngineConfiguration"/>
</bean>

<bean id="customBehaviorFactory" class="com.hand.hap.activiti.custom.CustomBehaviorFactory"/>

<bean id="activitiBeanProvider" class="com.hand.hap.activiti.custom.ActivitiBeanProvider"/>

<bean id="notificationListener" class="com.hand.hap.activiti.listeners.NotificationListener"/>


<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
    <property name="dataSource" ref="dataSource"/>
    <property name="transactionManager" ref="transactionManager"/>
    <property name="databaseSchemaUpdate" value="true"/>

    <property name="mailServerHost" value="smtp.126.com"/>
    <property name="mailServerPort" value="25"/>
    <property name="mailServerUsername" value="hap_dev@126.com"/>
    <property name="mailServerPassword" value="hapdev11"/>

    <property name="asyncExecutorActivate" value="true"/>

    <property name="dbIdentityUsed" value="false"/>

    <property name="activityBehaviorFactory" ref="customBehaviorFactory"/>

    <property name="groupDataManager" ref="customGroupDataManager"/>
    <property name="userDataManager" ref="customUserDataManager"/>

    <property name="beans" ref="activitiBeanProvider"/>

    <property name="customDefaultBpmnParseHandlers" >

        <list>
            <bean class="com.hand.hap.activiti.custom.AddListenerUserTaskParseHandler">
                <constructor-arg index="0" value="create"/>
                <constructor-arg index="1" ref="notificationListener"/>
            </bean>
        </list>
    </property>
</bean>

Answer 1

检查bean customUserDataManager和processEngineConfiguration您对processEngineConfiguration中customUserDataManager的构造函数引用以及bean customUserDataManager中processEngineConfiguration的属性引用所以它肯定是一个循环引用。

<强>更新

除上述循环引用外，请检查customGroupDataManager bean以获取循环引用。

Answer 2

是的，有：

customUserDataManager需要processEngineConfiguration，它需要customUserDataManager，并且圆圈开始。

关于linux的循环引用
