java - Spring 3.2 ehcache 的缓存 NamespaceHandler

Question

*强文本*我在运行 Java SE +Spring 应用程序时遇到以下错误。我在互联网和这个网站上发现了类似的问题，但找不到正确的解决方案。我认为问题是缺少jar文件。

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring]

Answer 1

您正在尝试使用 ehcache-spring-annotations，但我在您的 POM 中没有看到依赖项。

尝试添加:

<dependency>
  <groupId>com.googlecode.ehcache-spring-annotations</groupId>
  <artifactId>ehcache-spring-annotations</artifactId>
  <version>1.2.0</version>
</dependency>

顺便说一句，如果您希望使用 Spring 对 @Cacheable 的 native 支持，则不需要此依赖项。所以只需删除

http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring
http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring/ehcache-spring-1.1.xsd

来自您的 Spring.xml 文件。
