Spring资源
问题:我想让以下 bean 定义(在 aaplicationContext.xml 中指定)作为“org.springframework.web.context.ContextLoaderListener”的可选。如果我没有正确提供“emsPropLocation”上下文参数,tomcat Web 容器将无法正确初始化,这是显而易见的原因。有什么办法让它成为可选的吗?
appicationContext.xml:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="false"/>
<property name="location" value="file:/#{contextParameters.emsPropLocation}" />
</bean>
<!-- TIBCO Connection Factory Bean -->
<bean id="tibcoConnectionFactory" class="com.tibco.tibjms.TibjmsConnectionFactory">
<constructor-arg value="${emsServerURL}"/>
<property name="userName" value="${emsUserName}"/>
<property name="userPassword" value="${emsPassword}"/>
<property name="connAttemptCount" value="${connAttemptCount}"/>
<property name="connAttemptDelay" value="${connAttemptDelay}"/>
<property name="connAttemptTimeout" value="${connAttemptTimeout}"/>
<property name="reconnAttemptCount" value="${reconnAttemptCount}"/>
<property name="reconnAttemptDelay" value="${reconnAttemptDelay}"/>
<property name="reconnAttemptTimeout" value="${reconnAttemptTimeout}"/>
</bean>
<!-- bean id="tibcoUtil" class="com.nr.ns.upload.TibcoUtil" scope="singleton">
<constructor-arg value="true"/>
</bean-->
<bean id="jmsExceptionListener" class="com.nr.ns.upload.LogMsgExceptionListener"/>
<!-- Spring CachingConnectionFactory Bean -->
<bean id="connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
<constructor-arg ref="tibcoConnectionFactory"/>
<property name="reconnectOnException" value="${reconnectOnException}"/>
<property name="sessionCacheSize" value="${sessionCacheSize}"/>
<property name="exceptionListener" ref="jmsExceptionListener"/>
</bean>
<!-- JMSTemplate Bean -->
<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
<constructor-arg ref="connectionFactory"/>
<property name="receiveTimeout" value="${receiveTimeout}"/>
<property name="deliveryMode" value="${deliveryMode}"/>
</bean>
我们将 WAR 文件保留在 tomcat 之外,并且为了实现这一点,我们在 TOMCAT_HOME/conf/Catalina/localhost 内有“app.xml”文件。
app.xml:
<Context path="/app"
docBase="/abc/ccp/app.war"
reloadable="true"
unpackWAR="false">
<Parameter name="emsPropLocation"
value="/xyz/config/EMSServerConf.properties"
override="false"/>
</Context>
Problem: I want to make the below bean definitions (specified in aaplicationContext.xml) optional for "org.springframework.web.context.ContextLoaderListener". If i am not providing the "emsPropLocation" context parameter correctly, tomcat web container is not able to initialized properly and it is obvious reason. Is there any way to make it optional?
appicationContext.xml:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="false"/>
<property name="location" value="file:/#{contextParameters.emsPropLocation}" />
</bean>
<!-- TIBCO Connection Factory Bean -->
<bean id="tibcoConnectionFactory" class="com.tibco.tibjms.TibjmsConnectionFactory">
<constructor-arg value="${emsServerURL}"/>
<property name="userName" value="${emsUserName}"/>
<property name="userPassword" value="${emsPassword}"/>
<property name="connAttemptCount" value="${connAttemptCount}"/>
<property name="connAttemptDelay" value="${connAttemptDelay}"/>
<property name="connAttemptTimeout" value="${connAttemptTimeout}"/>
<property name="reconnAttemptCount" value="${reconnAttemptCount}"/>
<property name="reconnAttemptDelay" value="${reconnAttemptDelay}"/>
<property name="reconnAttemptTimeout" value="${reconnAttemptTimeout}"/>
</bean>

We are keeping WAR file outside tomcat and to make it happen we have "app.xml" file inside TOMCAT_HOME/conf/Catalina/localhost.
app.xml:
<Context path="/app"
docBase="/abc/ccp/app.war"
reloadable="true"
unpackWAR="false">
<Parameter name="emsPropLocation"
value="/xyz/config/EMSServerConf.properties"
override="false"/>
</Context>

尝试将 propertyConfigurer 的ignoreResourceNotFound 属性更改为true。
have a try to change the ignoreResourceNotFound property of your propertyConfigurer to true.
如果未设置 contextParameters.emsPropLocation,则默认为冒号后面的位置。
If contextParameters.emsPropLocation is not set, this will default to what is afer the colon.
