运行spring batch war文件时出错

我创建了一个弹簧批处理项目，并使用maven为

创建了一个war文件 
 <modelVersion>4.0.0</modelVersion>
  <groupId>com.batch</groupId>
  <artifactId>dms-batch-app</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>dms-batch-app Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <properties>
        <jdk.version>1.8</jdk.version>
        <spring.version>4.0.6.RELEASE</spring.version>
        <spring.batch.version>3.0.7.RELEASE</spring.batch.version>
        <quartz.version>1.8.5</quartz.version>


  <build>
    <finalName>dms-batch-app</finalName>
    </build>

我能够生成war文件，但是当我在tomcat服务器上部署并启动tomcat应用程序时，它会抛出以下错误

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

我连接到xml上下文中的数据库，如下所示

<jdbc:initialize-database data-source="dataSource">
 <jdbc:script location="org/springframework/batch/core/schema-drop-mysql.sql" />
<jdbc:script location="org/springframework/batch/core/schema-mysql.sql" />
  </jdbc:initialize-database>

但是根据错误，战争无法从jar文件中读取。我也修改了同样的东西，并将ddl脚本保存在resources文件夹下，但战争再次从jar文件本身中选择ddl脚本。

请为此提供解决方案。

而且，将弹出批处理项目部署为jar文件或war文件会有什么更好的选择呢？

请帮助。

答案 0 :(得分：1)

试试这个版本：

  1. <jdbc:script location="/org/springframework/batch/core/schema-drop-mysql.sql" /> <jdbc:script location="/org/springframework/batch/core/schema-mysql.sql" />
  2. <jdbc:script location="classpath:/org/springframework/batch/core/schema-drop-mysql.sql" /> <jdbc:script location="classpath:/org/springframework/batch/core/schema-mysql.sql" />
  3. <jdbc:script location="jar:file:org/springframework/batch/core/schema-drop-mysql.sql" /> <jdbc:script location="jar:file:org/springframework/batch/core/schema-mysql.sql" />
