spring-batch-admin的其他属性文件 [英] Additional properties files for spring-batch-admin

问题描述

我有一个使用spring-batch的Web应用程序，现在正在集成spring-batch-admin进行基本管理.

I have a web application using spring-batch and I'm now integrating spring-batch-admin for basic administration.

问题是作业配置文件(与现有应用程序的配置共享)使用我应用程序的类路径中文件的属性，但是spring-batch-admin的上下文无法加载它们.

The problem is that the jobs configuration files (which are shared with the configuration of the existing application) use properties from files in my application's classpath, but spring-batch-admin's context is not able to load them.

快速解决方案是覆盖placeholderProperties

The quick solution was to override the placeholderProperties bean in spring-batch-admin just to add my properties files:

<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:/path/to/jobs-config.properties</value> <!-- adding my properties here -->
        </list>
    </property>
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
    <property name="ignoreResourceNotFound" value="true" />
    <property name="ignoreUnresolvablePlaceholders" value="false" />
    <property name="order" value="1" />
</bean>

我不想将我的属性移动到spring-batch-admin的默认文件之一.有没有更简单的方法可以做到这一点?

I don't want to move my properties to one of spring-batch-admin's default files. Is there a simpler way to do this?

推荐答案

在这里回答我自己的问题...

Answering my own question here...

如文档所述，放置在META-INF/spring/batch/jobs/*.xml下的配置文件由spring-batch-admin作为子上下文和父项的属性占位符加载(即

As described in the documentation, every job configuration file placed under META-INF/spring/batch/jobs/*.xml is loaded by spring-batch-admin as a child context and property placeholders from the parent (i.e. this default bean) are inherited, but the child context can always create its own placeholder bean.

鉴于在我的情况下，作业配置文件与现有应用程序共享并使用应用程序类路径中的属性，解决方案是在META-INF/spring/batch/jobs/*.xml中创建特定于spring-batch-admin的新作业文件:

Given that, in my case, the job configuration files are shared with an existing application and use properties from the application classpath, the solution is to create a new job file in META-INF/spring/batch/jobs/*.xml specific for spring-batch-admin:

<!-- placeholder bean with additional properties for the child context -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <list>
            <value>classpath:/path/to/job-config.properties</value>
        </list>
    </property>
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
    <property name="ignoreResourceNotFound" value="true" />
    <property name="ignoreUnresolvablePlaceholders" value="false" />
    <property name="order" value="1" />
</bean>

<!-- external job configuration file is imported -->
<import resource="classpath*:/path/to/job.xml" />
