这似乎是一个愚蠢的问题。我正在尝试为 Spring Batch Job Repository (Spring Batch 2.1.7) 配置 Oracle10g 数据库,我能够使用org/springframework/batch/core/schema-oracle10g.sql中可用的脚本创建表。我还将属性batch.data.source.init设置为false。
在一个干净的数据库上,我的批处理程序运行良好,成功创建了所有批处理表/序列并用批处理结果的详细信息填充它们。但是,当我再次运行它时,Spring Batch 尝试再次创建这些表并抛出“ORA-00955:名称已被现有对象使用”异常。我究竟做错了什么?
# For Oracle
batch.jdbc.driver=oracle.jdbc.driver.OracleDriver
batch.jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl
batch.jdbc.user=****
batch.jdbc.password=****
batch.schema=****
batch.schema.script=classpath:/org/springframework/batch/core/schema-oracle10g.sql
batch.drop.script=classpath:/org/springframework/batch/core/schema-drop-oracle10g.sql
batch.jdbc.testWhileIdle=true
batch.data.source.init=false
以下是我的上下文文件:
