java - 尾部部分不允许有内容 - 使用 struts2-spring-hibernate

Question

我是这个框架的新手。我从一些示例/教程开始，但我现在已经开始了。我相信错误在 application-Context.xml 中，在配置 spring 中，但我不知道在哪里。

我收到此错误:

Answer 1

您已经在 bean xml 配置中提到了构造函数参数:

   <bean id="ListingEventos" class="com.app.struts.actions.eventos.ListingEventos">
        <constructor-arg name="eventoService"  ref="eventoService" />   
    </bean>

但是您的 ListingEventos 类文件中没有这样的构造函数。您需要添加相应的构造函数。
