Question

我有一个批处理文件，它将使用config.properties设置系统属性并执行一个jar文件。 jar中的Spring上下文文件需要加载此属性文件，以在上下文文件中设置相关bean的jdbc连接设置。但我得到文件未找到错误，如下所示。任何帮助表示赞赏。提前谢谢。

批处理文件内容：

set JAVA_OPTS=%JAVA_OPTS% -Dconfig.properties.name=../config.properties
java -classpath .;../lib/xyz.jar ax.bx.cx.ABCClass

jar中的Spring上下文文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:util="http://www.springframework.org/schema/util"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd">

<context:property-placeholder location="classpath:${config.properties.name}"/>

<!-- other beans declared below -->

</beans>

Answer 1

<bean id="propertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="systemPropertiesModeName">
        <value>SYSTEM_PROPERTIES_MODE_FALLBACK</value>
    </property>
</bean>


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

现在，由于您正在使用上下文模式，请按如下所示修改beans标记 -

<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:util="http://www.springframework.org/schema/util"
        xmlns:aop="http://www.springframework.org/schema/aop"
        xsi:schemaLocation="
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">

//.....

</beans>
