Spring Batch管理员在特定路径中搜索配置。此页面说明了它从哪个路径加载资源：
<import resource="classpath*:/Meta-INF/spring/batch/bootstrap/**/*.xml"/>
<import resource="classpath*:/Meta-INF/spring/batch/override/**/*.xml"/>
请注意，在Spring Batch Admin发行版中，“覆盖”位置中没有文件。这是供用户添加自己的内容的占位符。
我们设法加载外部属性文件，并在src/main/resources/Meta-INF/spring/batch/override/manager/env- context.xml其中放置xml配置文件，如下所示：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<!-- Use this to set additional properties on beans at run time -->
<bean id="placeholderProperties"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:/org/springframework/batch/admin/bootstrap/batch.properties</value>
<value>classpath:batch-default.properties</value>
<value>classpath:batch-${ENVIRONMENT:hsql}.properties</value>
<value>classpath:batch-${ENVIRONMENT:MysqL}.properties</value>
<!-- here we load properties from external config folder -->
<value>file:${spring.file.location}</value>
</list>
</property>
<property name="systemPropertiesModeName" value="SYstem_PROPERTIES_MODE_OVERRIDE" />
<property name="ignoreResourceNotFound" value="false" />
<property name="ignoreUnresolvablePlaceholders" value="false" />
<property name="order" value="1" />
</bean>
</beans>
