Question

我将Spring批处理应用程序集成到Spring Batch Admin中 - 我收到以下错误无法在字符串值“$ {batch.business.schema.script}”中解析占位符'batch.business.schema.script'

请参考我的other answer来查看代码结构。

我不再使用Spring Batch管理员但我记得收到这个错误，我这样解决了。

在重写文件 - src\main\resources\META-INF\spring\batch\override\env-context.xml中，我改变了这个，

<bean id="placeholderProperties" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <!--  Below two lines are commented by Sabir-->
                <!--  <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:application.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>

注意这一行 - <value>classpath:batch-${ENVIRONMENT:hsql}.properties</value>

然后我创建了一个文件 - src\main\resources\batch-db2.properties，因为我的db是db2。

batch.job.configuration.package=****You put your java package ****


batch.drop.script=classpath*:/org/springframework/batch/core/schema-drop-db2.sql
#Not needed in our case since we are already using runId incrementer
#batch.database.incrementer.class=org.springframework.jdbc.support.incrementer.DB2SequenceMaxValueIncrementer
batch.schema.script=classpath:DB2_BATCH_DDL.sql
batch.business.schema.script=classpath:/business-schema-db2.sql

#Copied from batch.properties of spring-batch-admin-manager API project
batch.jdbc.testWhileIdle=false
batch.jdbc.validationQuery=
batch.data.source.init=false
batch.job.configuration.file.dir=target/config
batch.job.service.reaper.interval=60000

batch.files.upload-dir=/sba/input

注意密钥 - batch.business.schema.script，根据您的数据库和数据，将该文件放在那里，并带有一些虚拟的SELECT SQL值。架构。

基本上，概念是Spring Batch管理员假定某些属性值＆amp;这些值应该被你覆盖。
