Question

我的项目需要从属性文件加载初始上下文工厂和提供程序URL。这是我的Spring配置

<bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate" lazy-init="true">
    <property name="environment">
        <props>
            <prop key="java.naming.factory.initial">${initial.context.factory}</prop>
            <prop key="java.naming.provider.url">${provider.url}</prop>
        </props>
    </property>
</bean>

<bean id="jmsQueueConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean" lazy-init="true" depends-on="jndiTemplate">
    <property name="jndiTemplate">
        <ref bean="jndiTemplate"/>
    </property>
    <property name="jndiName">
        <value>${queue.connection.factory}</value>
    </property>
</bean>

这是我的Spring容器初始化的方法

    PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
    ppc.setProperties(ConfigManager.getProperties());
    AbstractApplicationContext context = new ClassPathXmlApplicationContext("spring-config.xml");
    context.addBeanFactoryPostProcessor(ppc);
    context.refresh();

QueueConnectionFactory初始化会抛出异常

线程“main”中的异常org.springframework.beans.factory.BeanCreationException：创建名为'jmsQueueConnectio的bean时出错 nFactory'在类路径资源中定义[spring-config.xml]：init方法的调用失败;嵌套异常是javax.naming.Com municationException [根异常是java.net.ConnectException：http://maven.apache.org/ingestionservices-core：没有已知的有效por t for：'Default [http]：http（http）：null：-1：192.168.50.160：-1';没有可用的目的地路由器] 在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean（AbstractAutowireCapableBeanFa） ctory.java:1412）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean（AbstractAutowireCapableBeanFact） ory.java:519）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean（AbstractAutowireCapableBeanFactor） y.java:456） at org.springframework.beans.factory.support.AbstractBeanFactory $ 1.getObject（AbstractBeanFactory.java:291）在org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton（DefaultSingletonBeanRegistry.java:222））在org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean（AbstractBeanFactory.java:288）在org.springframework.beans.factory.support.AbstractBeanFactory.getBean（AbstractBeanFactory.java:190）在org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean（AbstractBeanFactory.java:281）在org.springframework.beans.factory.support.AbstractBeanFactory.getBean（AbstractBeanFactory.java:190）在org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean（AbstractBeanFactory.java:281）在org.springframework.beans.factory.support.AbstractBeanFactory.getBean（AbstractBeanFactory.java:190）在org.springframework.context.support.AbstractApplicationContext.getBean（AbstractApplicationContext.java:1075）在com.quickplay.ingestionservices.poolmgr.PoolManager.initialize（PoolManager.java:143）在com.quickplay.ingestionservices.poolmgr.PoolManager。（PoolManager.java:56）在com.quickplay.ingestionservices.poolmgr.PoolManager.main（PoolManager.java:47）

似乎未正确配置provider.url属性。如果我对提供者URL进行硬编码，它就有效。有人可以指出发生了什么吗？感谢

修改现有的config.xml文件

 <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location">
        <value>classpath:project.properties</value>
    </property>
</bean>


<bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate" lazy-init="true">
    <property name="environment">
        <props>
            <prop key="java.naming.factory.initial">${initial.context.factory}</prop>
            <prop key="java.naming.provider.url">${provider.url}</prop>
        </props>
    </property>
</bean>

<bean id="jmsQueueConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean" lazy-init="true" depends-on="jndiTemplate">
    <property name="jndiTemplate">
        <ref bean="jndiTemplate"/>
    </property>
    <property name="jndiName">
        <value>${queue.connection.factory}</value>
    </property>
</bean>

创建属性文件“project.properties”，放在类路径

中

# jndiTemplate Info
queue.connection.factory="value..."
provider.url="value..."
initial.context.factory="value..."

Spring，JndiTemplate外化提供程序URL
