<!-- 配置Handler -->

<!-- 注解的handller
实际开发中建议使用组件扫描

<!-- 可以扫描controller service -->

<!-- 处理器映射器
将bean的那么作为url进行查找,需要在配置Handler是指定beanname

<!-- 简单url映射 -->
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<!-- 对ItemsController1进行url映射 -->
<prop key="/queryItems1.action">ItemsController1</prop>

<prop key="/queryItems3.action">ItemsController3</prop>
</props>
</property>

<!--注解适配器 -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/>
<!-- 使用 mvc:annotation-driven可以代替注解映射器、注解适配器的配置
默认加载了很多参数绑定方法,例如json转换解析器
实际开发中用这个配置
-->
<mvc:annotation-driven></mvc:annotation-driven>
<!-- 视图解析器
解析jsp,默认使用jstl标签
