java - 我无法使用 aries jpa/v2.0.0 和 transactions/v2.0.0

Question

我尝试启用并 int blueprint.xml 但出现错误。这是我的 xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
           xmlns:jpa="http://aries.apache.org/xmlns/jpa/v2.0.0"
           xmlns:tx="http://aries.apache.org/xmlns/transactions/v2.0.0"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 https://osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
           http://aries.apache.org/xmlns/jpa/v2.0.0
           http://aries.apache.org/xmlns/transactions/v2.0.0 ">
    <jpa:enable/>
    <tx:enable-annotations/>
    <service ref="userService" interface="domain.access.UserService"/>
    <bean id="userService" class="domain.access.impl.UserServiceImpl" scope="singleton">
    </bean>
</blueprint>

这是我在 pom.xml 中的依赖项，我包含了所有库，也许我忘记了一些东西

当我开始捆绑时，我有宽限期并记录在日志中

Answer 1

在事务 2.0.0 命名空间中，xml 元素名为 <tx:enable/>不是<tx:enable-annotations/> 。但这与您描述的错误无关。

该错误表明您没有安装正确的 Aries JPA bundle 。确保安装所有必需的功能，如this example .

pom 中的依赖项仅涵盖构建时间。在运行时，您必须提供依赖项作为 karaf 功能或单独的 bundle 。

还要确保您使用最新的 Apache Karaf。旧版本不包含 aries transaction 2.0.0 bundle 。
