在 Spring MVC (2.0) 中，如何轻松挂钩多个页面/url 以使用 1 个控制器？

Question

<!--dispatcher file-->
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="mappings">
    <props>
      <prop key="/foo/bar/baz/boz_a.html">bozController</prop>
    </props>
  </property>
</bean>



<!--mappings file-->
<bean id="bozController" class="com.mycompany.foo.bar.baz.BozController">
    <property name="viewPathA" value="foo/bar/baz/boz_a" />
    <property name="viewPathB" value="foo/bar/baz/boz_b" />
    ...
    <property name="viewPathZ" value="foo/bar/baz/boz_z" />
</bean>

如何设置以便当用户加载页面 boz_w.html 时它使用 bozController，并将 viewPath 设置为使用 boz_w.jsp？

即使使用 Spring 2.0，您也可以使用 Spring 注解。当您想要将多个 url 映射到 simgle Controller 时，您可以使用 MultiActionController，如下所示

package br.com.spring.view;

// Do not use @Controller when using Spring 2.0 MVC Controller
// It does not work as expected
// Use @Component instead
@Component
public class MutliPurposeController extends MultiActionController {

    @Autowired
    private Service service;

    // mapped to /mutliPurpose/add
    public ModelAndView add(...) {}

    // mapped to /mutliPurpose/remove
    public ModelAndView remove(...) {}

    // mapped to /mutliPurpose/list
    public ModelAndView list(...) {}

}

您的 WEB-INF/-servlet.xml 如下所示

<beans ...>
    <context:component-scan base-package="br.com.spring.view"/>
    <context:annotation-config/>
    <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping">
        <property name="order" value="0"/>
        <property name="caseSensitive" value="true"/>
    </bean>
</beans>
