添加 spring-data-jpa 架构引用后,Spring 配置 xml 无效 [英] Spring config xml isn't valid after adding spring-data-jpa schema references
本文介绍了添加 spring-data-jpa 架构引用后,Spring 配置 xml 无效的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在启动 spring 上下文时出现以下异常:
I have the following Exception while starting the spring context:
java.lang.Exception: java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: org.xml.sax.SAXParseException; systemId: http://www.springframework.org/schema/data/jpa/; lineNumber: 1; columnNumber: 55; White spaces are required between publicId and systemId.
在我将 spring-data-jpa 添加到 spring config.xml 之前,一切正常.为什么 xml 不再有效?
Before I added the spring-data-jpa to the spring config.xml everything worked fine. Why isn't the xml not valid anymore?

推荐答案
请重新排列以下几行:
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/data/jpa
http://www.springframework.org/schema/data/jpa/spring-jpa.xsd
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
...至此:
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/data/jpa
http://www.springframework.org/schema/data/jpa/spring-jpa.xsd
这正是您的错误消息指向的地方,成对外观(命名空间位置
)是 相关!
This is exactly where your error message points at, and the pair-wise appearance (namespace location
) is relevant!
