java - 处理 XML 时发生错误“无法加载类 [org.springframework.transaction.annotation.AnnotationTransactionAttributeSource]

Question

请我需要配置文件applicationcontext.xml，我使用hibernate 5.2.10和spring 3.1.1。
我已经有了这个配置，但有一个错误:

"Error occured processing XML 'Unable to load class [org.springframework.transaction.annotation.AnnotationTransactionAttributeSource]. Are you running on Java 1.5+? Root cause: java.lang.NoSuchMethodError: org.springframework.util.ClassUtils.forName(Ljava/lang/String;)Ljava/lang/Class;'. See Error Log for more details"

请确保在您的项目中使用与框架兼容的最新 Java 版本。 (1.5+)

如果您使用 Maven，请尝试使用以下属性。

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>
