我对spring mvc有问题

<bean
    class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />

<bean id="urlMapping"

    <property name="mappings">

<bean name="welcomeController"

<bean name="/bscList.htm" class="cbs.web.BscController">
    <property name="bscDao" ref="myBscDao" />

<bean name="/bscForm.htm" class="cbs.web.BscFormController">
    <property name="commandName" value="bsc"/>
    <property name="commandClass" value="cbs.domain.Bsc"/>
    <property name="formView" value="bscForm"/>
    <property name="successView" value="bscList.htm"/>
    <property name="bscDao" ref="myBscDao"/>
</bean>

</beans>

我的表单控制器

public class BscFormController extends SimpleFormController {

private static Logger log = Logger.getLogger(BscController.class);
private BscDao bscDao;

public void setBscDao(BscDao bscDao) {
    this.bscDao = bscDao;
}

protected Object formBackingObject(HttpServletRequest request)
        throws Exception {
    String id = request.getParameter("id");

    if (!StringUtils.isBlank(id)) {
        return bscDao.get(new Integer(id));
    }

    return new Bsc();
}

public ModelAndView onSubmit(HttpServletRequest request,
        HttpServletResponse response, Object command, BindException errors)
        throws Exception {
    log.debug("entering 'onSubmit' method...");

    Bsc bsc = (Bsc) command;
    String success = getSuccessView();

    if (request.getParameter("delete") != null) {
        bscDao.remove(bsc.getId());
    } else {
        bscDao.save(bsc);
    }

    return new ModelAndView(success);
}
}

我的问题：当我访问/bscList.htm时，它是bsc（bscList.jsp模板）的显示列表，但是当我访问/bscForm.htm时，它仍然显示bsc的列表，而不是显示我的表单（bscForm.jsp模板）

我用一些简单的控制器进行测试：

控制器实现org.springframework.web.servlet.mvc.Controller，evething正常运行
controller扩展SimpleFormController，映射错误：在DispatcherServlet中找不到带有URI [/cbs/testform.htm]的HTTP请求的映射，名称为“dispatcher”

Answer 1

当我使用HandlerMapping ControllerClassNameHandlerMapping时，所有请求URL'/ bsc *'将映射到BscController（/bscForm.htm将不会映射到BscFormController）

spring-mvc：表单控制器的错误映射URL
