CdiJtaProcessEngineConfiguration 在加载之前请求事务管理器

Question

我成功地让 Activiti 使用 JtaProcessEngineConfiguration 并单独使用 CdiStandaloneProcessEngineConfiguration。

但是我无法让 CdiJtaProcessEngineConfiguration 工作，我的配置示例如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans <a href="http://www.springframework.org/schema/beans/spring-beans.xsd">

" rel="nofollow">http://www.springframework.org/schema/beans/spring-beans.xsd">

</a>    <bean id="transactionManager" class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName" value="java:comp/TransactionManager"></property>
        <property name="resourceRef" value="true" />
    </bean>

    <bean id="processEngineConfiguration" class="org.activiti.cdi.CdiJtaProcessEngineConfiguration">
        <property name="transactionManager" ref="transactionManager" />
        <property name="transactionsExternallyManaged" value="true" />

        <property name="dataSourceJndiName" value="openejb:Resource/jdbc/AppDS" />
        <property name="databaseSchemaUpdate" value="false"/>

        <property name="jobExecutorActivate" value="false"/>
        <property name="asyncExecutorEnabled" value="true"/>
        <property name="asyncExecutorActivate" value="true"/>
        <property name="history" value="audit"/>
    </bean>
</beans>

错误是

javax.naming.NameNotFoundException: Name [TransactionManager] is not bound in this Context. Unable to find [TransactionManager].

堆栈跟踪如下

2016-11-29 13:47:37 ERROR ProcessEngines:174 - Exception while initializing process engine: Error creating bean with name 'processEngineConfiguration' defined in resource loaded through InputStream: Cannot resolve reference to bean 'transactionManager' while setting bean property 'transactionManager';

        at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveValueIfNecessary

我不确定接下来要尝试什么

我使用的应用服务器是Tomee-plus 1.7.3

干杯亚当

[编辑 1] 请注意，您需要在应用准备就绪时加载 JtaProcessEngineConfiguration 手册，但 CdiStandaloneProcessEngineConfiguration 和 CdiJtaProcessEngineConfiguration 会通过 ActivitiExtension class.

自动加载

[编辑 2] 在扩展的 JtaProcessEngineConfiguration（无 cdi）中按如下方式查找事务管理器时（根据@Romain Manni-Bucau 建议）

    try {
        InitialContext initialContext = new InitialContext();
        try {
            transactionManager = (TransactionManager) initialContext.lookup("openejb:Resource/TransactionManager");
        } finally {
            initialContext.close();
        }

    } catch (NamingException e) {
        LOGGER.error(e.getMessage(), e);
    }

我得到以下异常跟踪

2016-12-06 09:16:35 ERROR TestJtaProcessEngineConfiguration:29 - Name     "Resource/TransactionManager" not found.
javax.naming.NameNotFoundException: Name "Resource/TransactionManager" not found.

[编辑 3] 尝试使用 "java.naming.factory.initial=org.apache.openejb.core.OpenEJBI‌nitialContextFactory" 导致以下堆栈跟踪。

Cannot instantiate class: org.apache.openejb.core.OpenEJBInitialContextFactory [Root exception is java.lang.ClassNotFoundException: org.apache.openejb.core.OpenEJBInitialContextFactory]

at javax.naming.InitialContext.init(InitialContext.java:244)
at javax.naming.InitialContext.<init>(InitialContext.java:216)

但是使用 "openejb:TransactionManager" 的 jndi 字符串是可行的

成功工作配置使用 jndiName 属性如下。

<property name="jndiName" value="openejb:TransactionManager"></property>

Answer 1

使用 openejb 怎么样：Resource/TransactionManager 容器一启动就可用（甚至在任何部署之前）？这将使依赖于事务管理器的任何代码不依赖于启动生命周期。

Answer 2

在@Romain Manni-Bucau 的帮助下，解决方案是 "openejb:TransactionManager"

的 jndi 名称

我允许我接受@Romain Manni-Bucau 回答的编辑被拒绝，在这里发布正确答案。
