Question

我成功地使Activiti能够使用JtaProcessEngineConfiguration并与CdiStandaloneProcessEngineConfiguration分开使用。

但我无法让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：名称[TransactionManager]不是绑定在这个上下文中。无法找到[TransactionManager]。

并且堆栈跟踪如下

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';

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，您需要在应用程序准备就绪时加载JtaProcessEngineConfiguration手册，但是通过ActivitiExtension类自动加载CdiStandaloneProcessEngineConfiguration和CdiJtaProcessEngineConfiguration。

[编辑2] 在扩展的JtaProcessEngineConfiguration（没有cdi）中按如下方式查询事务管理器（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]试图使用＆＃34; java.naming.factory.initial = org.apache.openejb.core.OpenEJBI nitialContextFactory＆＃34;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.spi.NamingManager.getInitialContext(NamingManager.java:674)
at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:313)
at javax.naming.InitialContext.init(InitialContext.java:244)
at javax.naming.InitialContext.<init>(InitialContext.java:216)

但是使用＆＃34; openejb：TransactionManager＆＃34;的jndi字符串;作品

SUCCESS 工作配置使用jndiName属性，如下所示。

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

Answer 1

使用openejb怎么样：Resource / TransactionManager在容器启动后立即可用（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

使用@Romain Manni-Bucau帮助解决方案是一个jndi名称＆＃34; openejb：TransactionManager＆＃34;

我的编辑允许我接受@Romain Manni-Bucau的回答被拒绝，在此发布了正确答案。

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