Spring + Maven: The matching wildcard is strict, but no declaration can be found for element 'jdbc:embedded-database'
提问by mavilein
i am currently trying to build a little webapp that uses Spring, Hibernate and Maven (running on a tomcat). It works quite fine, except that i cannot get my embedded-database to work. I hope you can help me.
我目前正在尝试构建一个使用 Spring、Hibernate 和 Maven（在 tomcat 上运行）的小网络应用程序。它工作得很好，除了我无法让我的嵌入式数据库工作。我希望你能帮助我。
I am always facing this error, when i am deploying the webapp to the Tomcat:
当我将 webapp 部署到 Tomcat 时，我总是面临这个错误：
The matching wildcard is strict, but no declaration can be found for element 'jdbc:embedded-database'
匹配的通配符是严格的，但找不到元素“jdbc:embedded-database”的声明
During my investigations i learned that this message is pointing towards missing libraries. Therefore i added my pom.xml, where i added the artifact spring-jdbc.
在我的调查中，我了解到此消息指向缺少的库。因此我添加了我的 pom.xml，在那里我添加了工件 spring-jdbc。
Can you help me finding the error? Thanks a lot!
你能帮我找出错误吗？非常感谢！
This is my spring-configuration-file, which causes the error during initialization of the webapp:
这是我的 spring-configuration-file，它在 webapp 初始化期间导致错误：

This line in your Spring context file:
您的 Spring 上下文文件中的这一行：
xmlns:jdbc="http://www.springframework.org/schema/jdbc/spring-jdbc-3.1.xsd"
should be changed to :
应改为：
xmlns:jdbc="http://www.springframework.org/schema/jdbc"
Not sure what IDE you're using but with some (IntelliJ for example) this would be flagged as an error and save a lot of headache!
不确定您使用的是什么 IDE，但对于某些（例如 IntelliJ），这将被标记为错误并省去很多麻烦！

For me it was to add xmlns:jdbc and xsi:schemaLocation
对我来说是添加 xmlns:jdbc 和 xsi:schemaLocation
<beans ....
xmlns:jdbc="http://www.springframework.org/schema/jdbc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
.....
http://www.springframework.org/schema/jdbc
http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd"
default-lazy-init="true">
also add
还添加
