Spring批處理管理員無法替換佔位符'batch.business.schema.script'

Question

試圖將Spring批處理管理員添加到現有的Spring批處理項目。

我已經更新的web.xml與彈簧批次管理資源和彈簧批次管理經理

我的設置：

在的src /主/資源/

我已添加2個屬性文件。圖1是分批 - 缺省 - 性質，這是一個空文件，而另一個是batch-sqlserver.properties均可進行以下內容：

batch.jdbc.driver=com.microsoft.sqlserver.jdbc.SQLServerDriver batch.jdbc.url=jdbc:sqlserver://xxx.xxx.xxx:1433;DatabaseName=SpringBatch 
batch.jdbc.user=user 
batch.jdbc.password=password 
batch.jdbc.testWhileIdle=false 
batch.jdbc.validationQuery= 
batch.drop.script=/org/springframework/batch/core/schema-drop-sqlserver.sql 
batch.schema.script=/org/springframework/batch/core/schema-sqlserver.sql 
batch.database.incrementer.class=org.springframework.jdbc.support.incrementer.SqlServerMaxValueIncrementer 
batch.lob.handler.class=org.springframework.jdbc.support.lob.DefaultLobHandler 
batch.business.schema.script=business-schema-sqlserver.sql 
batch.database.incrementer.parent=columnIncrementerParent 
batch.grid.size=2 
batch.jdbc.pool.size=6 
batch.verify.cursor.position=true 
batch.isolationlevel=ISOLATION_SERIALIZABLE 
batch.table.prefix=BATCH_ 
batch.data.source.init=false 

下web應用/ META-INF /彈簧/批次/超馳/，我已經添加了data-source-context.xml內容：

<?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"> 

     <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> 
       <property name="jndiName"> 
        <value>java:jboss/datasources/springBatchDB</value> 
       </property> 
     </bean> 
</beans> 

這是在JBoss EAP 6.3中運行的。每次我啓動服務器，它給出了這樣的例外：

11:58:36,116 WARN [org.springframework.web.context.support.XmlWebApplicationContext] (ServerService Thread Pool -- 112) Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'org.springframework.jdbc.datasource.init.DataSourceInitializer#0' defined in null: Could not resolve placeholder 'batch.business.schema.script' in string value "${batch.business.schema.script}"; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'batch.business.schema.script' in string value "${batch.business.schema.script}"

我看到batch.business.schema.script是來自：

spring-batch-admin-manager/src/main/resources/META-INF/spring/batch/bootstrap/manager/data-source-context.xml，

在那裏也有「$ { batch.schema.script}「，它是從我的batch-sqlserver.properties而不是batch.business.schema.script加載的。

有誰知道爲什麼或有任何建議？ 謝謝！

Answer 1

我也遇到了這個問題。我沒有一個單獨的覆蓋data-source-context.xml，但我解決了啓動服務器（在我的情況下的tomcat）與JVM選項稱爲環境：

-DENVIRONMENT=postgresql。

你的情況，那就是：

-DENVIRONMENT=sqlserver

我的猜測是，Spring Batch的應用程序使用Spring配置文件來選擇要使用的數據庫類型和需要在初次標誌播種的東西。

僅供參考，這裏是從大衛Syer後在此：

http://forum.spring.io/forum/spring-projects/batch/105054-spring-batch-admin-configuration-for-pointing-the-database?p=562140#post562140

對於代用上下文的做法，他說：

或者你可以用覆蓋XML走，只要因爲您將它放在 的正確位置 - 從用戶指南「將您自己的 相同bean定義添加到彈簧XML配置文件中」 META-INF/spring/batch/override「（這是在類路徑中，而不是戰爭 文件META-INF）。在這種情況下，只需重寫名爲 「dataSource」的bean。

所以你有錯誤的地方的文件。您需要將其移動到您的類路徑中的目錄。

Answer 2

嘗試覆蓋佔位符屬性，包括您自己的屬性。

我們假設你放在application.properties你的屬性，那麼這將是：

<?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: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> 

</beans>
