我的 Spring Web 应用程序出现 500 错误。提到的文件被正确命名并在正确的包中。这是错误信息。
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping': Invocation of init method failed; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.dao.CommentDAO] for bean with name 'commentDAO' defined in ServletContext resource [/WEB-INF/ghs1986-servlet.xml]; nested exception is java.lang.ClassNotFoundException: com.dao.CommentDAO

这是 ghs1986-servlet.xml 的相关部分。
<bean id="commentDAO" class="com.dao.CommentDAO">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="pagesController" class="com.controller.PagesController" />
<bean id="commentController" class="com.controller.CommentController">
<property name="commentDAO" ref="commentDAO" />
</bean>
答案 0 :(得分:0)
问题解决了。我需要 CommentDAO 上的 @Component 注释。
