我用Spring 3 MVC编写了“Hello World”网站,现在我正在尝试使用Apache Tiles技术重写它。我正在使用Maven来构建我的项目。 的pom.xml

}
}
我在WEB-INF的views目录中定义了footer.jsp,home.jsp,header.jsp和layout.jsp。为什么我会收到此错误?

请添加到您的dispatcher.servlet.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:beans="http://www.springframework.org/schema/beans"

<context:annotation-config />

<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">

<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
<property name="definitions">

</property>
</bean>
这个
<context:annotation-config/>
将激活各种注释,例如@Required和@Autowired
这个
<mvc:annotation-driven />
需要具有注释驱动的控制器。
下面的配置只是扫描类路径以获取带注释的组件。
<context:component-scan base-package="com.antenna.nn.patient" />
UrlBasedViewResolver是viewResolver,允许将符号视图名称直接解析为URL。瓷砖需要这个。
