JBoss-AS7 @TransactionTimeout:缺少Maven依赖项 [英] JBoss-AS7 @TransactionTimeout: Missing Maven dependency

问题描述

我正在使用 JBoss AS 7.1.1.Final"Brontes" ，并且在@Stateless -Bean中遇到了长时间运行的方法调用 5分钟后取消:

[com.arjuna.ats.arjuna] (Transaction Reaper) ARJUNA012117:
                        TransactionReaper::check timeout

搜索此问题，我找到了一些答案 JBoss-AS7参考指南或 JBoss Wiki .

答案似乎很简单:用@TransactionTimeout注释方法 但是:该课程在我的课程路径中不可用！ 我有一个具有EAR结构的Maven项目，并且ejb模块具有以下相关依赖关系，我在大量使用EJB3的多个项目中使用了这些依赖关系:

• org.jboss.spec.javax.ejb:jboss-ejb-api_3.1_spec(提供)
• javax.enterprise:cdi-api(提供)
• org.hibernate.javax.persistence:hibernate-jpa-2.0-api(提供)
• org.hibernate:hibernate-validator(提供)

缺少哪个依赖项?

解决方案

尝试一下；进行了相当认真的搜索才能发现它，但似乎应该可以:

<dependency>
    <groupId>org.jboss.ejb3</groupId>
    <artifactId>jboss-ejb3-ext-api</artifactId>
    <version>2.0.0</version>
    <scope>provided</scope>
</dependency>

• https ://github.com/jbossejb3/jboss-ejb3-ext-api/blob/master/src/main/java/org/jboss/ejb3/annotation/TransactionTimeout.java

我认为Petr发现的是较旧的一个(最初是针对JBoss 4.2.x)；如Thor所言，它不包含unit参数，并且可能不适用于AS7.

对于任何更新 JBAS7 EJB参考指南的人来说都是卑微的建议.也许可以包含@TransactionTimeout的Maven详细信息?

I'm using JBoss AS 7.1.1.Final "Brontes" and encountering a long running method call in a @Stateless-Bean which is cancelled after 5 Minutes:

[com.arjuna.ats.arjuna] (Transaction Reaper) ARJUNA012117:
                        TransactionReaper::check timeout

Searching for this issue I've found some answers Jboss 7.1 ejb 2.1 custom transaction timeout configuration and wikis JBoss-AS7 reference guide or JBoss Wiki.

The answer seems to be simple: Annotate the method with @TransactionTimeout But: This class is not available in my classpath! I have a Maven project with an EAR structure and the ejb module has the following relevant dependencies which I use in several projects with heavy usage of EJB3:

• org.jboss.spec.javax.ejb:jboss-ejb-api_3.1_spec (provided)
• javax.enterprise:cdi-api (provided)
• org.hibernate.javax.persistence:hibernate-jpa-2.0-api (provided)
• org.hibernate:hibernate-validator (provided)

Which dependency is missing?

解决方案

Try this one; it took some pretty serious searching to unearth it, but it seems like it should work:

<dependency>
    <groupId>org.jboss.ejb3</groupId>
    <artifactId>jboss-ejb3-ext-api</artifactId>
    <version>2.0.0</version>
    <scope>provided</scope>
</dependency>

• https://github.com/jbossejb3/jboss-ejb3-ext-api/blob/master/src/main/java/org/jboss/ejb3/annotation/TransactionTimeout.java

I think that the one Petr found is the older one (originally for JBoss 4.2.x); as Thor mentioned, it doesn't include the unit parameter, and may not work with AS7.

A humble suggestion for whomever updates the JBAS7 EJB reference guide; maybe the Maven details for @TransactionTimeout could be included?
