我在蓝图中使用cm:property-placeholder来加载配置文件:
<!-- External configuration -->
<cm:property-placeholder persistent-id="mubyndle" update-strategy="reload">
<cm:default-properties>
<cm:property name="schemaValidation" value="false"/>
</cm:default-properties>
</cm:property-placeholder>
<bean id="myBean" class="com.mybean">
<property name="abc" value="${abc}" />
</bean>
我可以将值设置为bean,例如$ {abc}。
如何从java访问配置的任何其他属性?
我打算添加属性列表: 为prop1 = 11 PROP2 = 22 ... propn = NN
由于数字不同,我无法在蓝图中添加所有内容。
谢谢你, 尤

在蓝图中添加对ConfigurationAdmin服务的引用:
<reference id="configAdmin" interface="org.osgi.service.cm.ConfigurationAdmin" />
将其设置为bean:
<bean id="myBean" class="com.mybean">
<property name="abc" value="${abc}" />
<property name="configAdmin" ref="configAdmin" />
</bean>
在豆中:
private ConfigurationAdmin configAdmin;
public void setConfigAdmin(ConfigurationAdmin configAdmin) throws IOException {
this.configAdmin = configAdmin;
System.out.println(configAdmin);
System.out.println(configAdmin.getConfiguration("any-persistent-id").getProperties());
}

您可以在org.apache.aries.blueprint.compendium.cm.CmPropertyPlaceholder
为<property name="cmpp" ref="cmpp" />
后将<cm:property-placeholder id="cmpp" ...
确定为my public void setProperties(CmPropertyPlaceholder properties) {
Configuration config = CmUtils.getConfiguration(properties.getConfigAdmin(), properties.getPersistentId());
if (config != null) {
Dictionary props = config.getProperties();
System.out.println(props);
}
。
然后在myBean中为cmpp添加setter:
org.apache.aries.blueprint.cm
唯一的问题是bundle org.apache.aries.blueprint.compendium.cm
没有导出包CmPropertyPlaceholder
,因此我无法访问java中的get_cachedir_bsig()
。在karaf中是否有任何命令可以另外导出捆绑包?
可以通过上下文访问配置,将查看并发布。

你最好这样做:
a)在blueprint.xml
中<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ext="http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.1.0"
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
...
<cm:property-placeholder persistent-id="<name of cfg file>"
update-strategy="reload">
<cm:default-properties>
<cm:property name="<property name in file>" value="<value>" />
</cm:default-properties>
</cm:property-placeholder>
<bean id="<name of Bean>" class="<full name of class>" >
<property name="<property name in file>" value="${<value>}"></property>
</bean>
b)内部&#34; bean&#34;
c)加入&#39; / etc&#39;文件夹配置文件:private <Type of> <name of variable>; public <Constructor> (){} // no parameters public void set<property name in file first upper letter>(<Type of> <property name in file>) { <name of variable> = <property name A>; }
<name of cfg file>.cfg
显然,在其中,属性:
<Property name> = <value>
