我想在我的应用程序中使用mybatis和容器管理事务。我使用mybatis 3.4.2和mybatis cdi 1.0.0

我的代码可以工作，但目前我手动打开和关闭会话，不知道如何将
SqlSession
或
Mapper
注入我的EJB

在我的情况下，
mybatis cdi
似乎不能正常工作

这是我的部署结构：

EAR
  +--- commons.jar (interfaces, POJOs)
  +--- ejb.jar (stateless EJBs + MyBatis mapper + session factory)
  +--- web.war (demo servlet which calls EJB)

当我使用我的
SessionFactoryProducerImpl
EJB来获取MyBatis会话时，一切正常，但我想让EE容器管理SqlSession（打开/关闭/提交/回滚）

这个问题是在我按照官方文件的建议修改了我的
SessionFactoryProducerImpl
之后出现的（删除@Stateless和接口引用，添加@products、@ApplicationScoped、@SessionFactoryProvider注释），之后

  • 我注入了
    org.apache.ibatis.session.SqlSession
    而不是我的
    sessionfactoryproduceripl
    在将EAR部署到服务器的过程中，我得到了一个
    类型SqlSession与qualifiers@Default
    的未满足的依赖项
  • 我注入MyBatis映射器，它是
    ConfigurationDao
    ，在我的例子中，然后我得到一个
    错误，没有正确配置的SqlSessionFactory生产者
    • 让EE容器管理MyBatis会话的正确方法是什么

    更新-1

    我尝试按名称插入SqlSessionFactory：

    //@Stateless
public class SessionFactoryProducerImpl /*implements SessionFactoryProducer*/ {
    //@Override
    @ApplicationScoped
    @Produces
    @Named("fooManager")
    @SessionFactoryProvider
    public SqlSessionFactory produce() throws IOException {
       ...
    }
}
    用法：

    @Stateless
public class EchoServiceBean implements EchoService {
    @Inject @Named("fooManager") ConfigurationDao configurationDao;
    ...
}
    从应用服务器登录：

    我可以看到我的
    SessionFactoryProducerImpl
    被注入@Stateless注释（bean id 70）或不注入@Stateless注释。我还可以看到SQLSessionFactoryProducer也被注入了bean id 58

    但是我仍然得到
    org.mybatis.cdi.mybatiscdigurationexception：当我调用EJB的
    echo（…）
    方法时，没有正确配置的SqlSessionFactory生产者
    

    我猜MyBatis需要使用
    a.b.ejb.SessionFactoryProducerImpl
    中的producer方法。但是如何告诉mybatis cdi呢？
    文档没有告诉您删除
    @Stateless
    ，只是没有指定它是必需的，因为它描述了一般用例。然后尝试：
    

    @Stateless
@Local(SessionFactoryProducer.class)
public class SessionFactoryProducerImpl implements SessionFactoryProducer {
    //@Override
    @ApplicationScoped
    @Produces
    @Named("fooManager")
    @SessionFactoryProvider
    public SqlSessionFactory produce() throws IOException {
       ...
    }
}

    

    @Local（SessionFactoryProducer.class）
    和
    实现SessionFactoryProducer
    甚至可能不是必需的
    
我假设
    @Stateless
    将
    SessionFactoryProducer
    转换成一个EJB，该EJB将在相同的上下文/范围中可用，并可以注入到另一个上下文/范围中
    

    SessionFactoryProducer
    只需出席即可。之后，CDI的任务是在找到SqlSession或Mapper注入点时调用它
    
这就是我所做的，会话由EJB管理。当然提供了mybatis-config.xml：
    

    <environments default="development">
  <environment id="development">
    <transactionManager type="MANAGED">
    <dataSource type="JNDI">

    

    

    首先，尝试部署示例应用程序。它已经在许多应用服务器上进行了测试，并且有一个示例EJB。然后只需将mybatis-config_1.xml更改为使用托管事务。会话工厂生产者不打算直接使用，而是由mybatis cdi内部使用。链接到示例应用程序：你是正确的。“@Local”和“implement”关键字不是必需的。正如我所见，“@无状态”也不是必需的。正如您在UPDATE-2中看到的，SqlSessionFactory被注入，但仍然会出现错误：（我的mybatis.xml与您的非常相似。神奇的是，只需要注释，CDI就可以完成所有工作。我认为无论如何都需要
    @Stateless
    ：即使SessionFactoryProducer被实例化，它也无法访问（不同的范围…这是错误日志所说的）要调用并用SqlSession/Mapper注入EJB，
    @Stateless
    将其转换为EJB，这与使用简单webapp（无EJB）时不同。您使用的是哪种应用服务器？我使用的是Jboss EAP 6.3
