使用 spring 在战争之外读取属性文件 [英] Read property file outside war using spring

问题描述

在此处输入代码我在 etc 文件夹中放置了一个属性文件.每个子模块中的myapplication.properties"和其他几个属性文件..我尝试执行以下操作

enter code hereI have a property file placed in the etc folder. "myapplication.properties" and few other property files in each sub module.. i am try to do the following

<bean class="org.springframework.web.context.support.ServletContextPropertyPlaceholderConfigurer">
    <property name="searchContextAttributes" value="true"/>
    <property name="contextOverride" value="true"/>
    <property name="ignoreResourceNotFound" value="true"/>
    <property name="locations">
        <list>
            <value>classpath:application.properties</value> 
            <value>${config}</value>
        </list>
    </property>
</bean>

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="ignoreUnresolvablePlaceholders" value="true"/>
</bean> 

我正在尝试 mvn -Dconfig=~/my.properties jetty:run

属性是从 application.properties 读取的，但不是用于 config..

The properties are read from application.properties but not for config..

在运行应用程序时，我得到的 ${jdbc.url} 不正确.. 这个 url 存在于 my.properties ..如何实现?

While running application i get the ${jdbc.url} not correct .. This url is present in my.properties .. How can this be achieved ?

谢谢

推荐答案

这就是我所拥有的，运行它

This is what I had, to run it

<bean id="placeholderConfigConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="systemPropertiesModeName">
        <value>SYSTEM_PROPERTIES_MODE_OVERRIDE</value>
    </property>
    <property name="ignoreUnresolvablePlaceholders">
        <value>true</value>
    </property>
</bean>

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location" value="file:${config}" />
</bean>

并在 MAVEN_OPTS 中添加 -Dconfig=/var//my.properties 并执行 mvn jetty:run

And add -Dconfig=/var//my.properties in the MAVEN_OPTS.. and did mvn jetty:run

我发现的另一种解决方案......而不是进行冗长的配置

Another one line solution I found.. instead of making verbose configuration just do

 <context:property-placeholder location="file:${config}"/>
