java - 使用spring DM迁移项目到Aries Blueprint的过程中，出现bean属性值不能正确转换的问题

Question

我正在将 spring-DM 迁移到 ariesblueprint

使用 java11 和 karaf 4.2.14

同时，aries blueprint 面临找不到合适的context.xml 值的转换器的问题，context.xml 定义了Apache Mina 的defaultLocalAddress。

它是我的 network-context.xml 的一部分。

<bean id="ioAcceptor" class="org.apache.mina.transport.socket.nio.NioSocketAcceptor">
    <property name="defaultLocalAddress" value=":8000"/>
    <property name="handler" ref="minaHandler"/>
    <property name="reuseAddress" value="true"/>
    <property name="filterChainBuilder" ref="filters"/>
</bean>

它在 SpringDM 中运行良好。

这句话本身似乎没有改变，所以我就照原样使用它。

有什么我忘记了或做了什么愚蠢的事吗？

如果这个问题很奇怪或愚蠢，请告诉我。

我不认为 Aries 支持本地类型转换器到InetSocketAddress.

您可以显式创建 a 的新实例InetSocketAddress：

<bean id="ioAcceptor" class="org.apache.mina.transport.socket.nio.NioSocketAcceptor">
    <property name="defaultLocalAddress" value=":8000">
      <bean class="java.net.InetSocketAddress">
        <argument value="8000"/>
      </bean>
    <property name="handler" ref="minaHandler"/>
    <property name="reuseAddress" value="true"/>
    <property name="filterChainBuilder" ref="filters"/>
</bean>

或注册您自己的类型转换器。

您应该实现org.osgi.service.blueprint.container.Converter并注册它<type-converter>
