我正在使用ActiveMQ蓝图来设置JMS连接池。 我还使用Camel来提供一些功能。
我使用org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer
允许在设置camel-context
文件时使用外部属性文件。
使用蓝图是否有类似的类型功能?
所以基本上,我想用我在下面的配置中从属性文件中获得的属性替换$ {server.address}:

您可以通过config admin:
使用系统属性和/或配置<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
xmlns:ext="http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.0.0">
<!-- Allow the use of system properties -->
<ext:property-placeholder placeholder-prefix="$[" placeholder-suffix="]" />
<!--
config admin properties from etc/com.example.config.cfg
-->
<cm:property-placeholder persistent-id="com.example.config" update-strategy="reload">
<cm:default-properties>
<cm:property name="configDir" value="$[karaf.base]/my-config" />
</cm:default-properties>
</cm:property-placeholder>
<bean id="config" class="com.example.Config">
<property name="rootDir" value="${configDir}" />
<property name="someSysProp" value="$[someSysProp]" />
</bean>
</blueprint>
“ext:property-placeholder”元素允许您通过定义的占位符前缀和后缀使用系统属性(如示例中的karaf.base),但这是可选的。如果您只需要自己的配置,可以通过etc /中的文件提供 etc / com.example.config.cfg并通过persistence-id。
