java – Spring MVC Controllers映射未注册

[weixin_38079736]

我现在用spring mvc进行一些测试,我有一个问题.对于要测试的基本应用程序,我选择本教程：http://loianegroner.com/2010/09/extjs-spring-mvc-3-and-hibernate-3-5-crud-datagrid-example/我已经下载了示例,一切都按预期工作.问题是当我尝试添加另一个Controller时.似乎我正在添加的文件未被扫描. 我的web.xml文件： <servlet> <servlet-name>extjs-crud-grid-spring-hibernate</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/spring/app-config.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>extjs-crud-grid-spring-hibernate</servlet-name> <url-pattern>*.action</url-pattern> </servlet-mapping> /WEB-INF/spring/app-config.xml： <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- Scans the classpath of this application for @Components to deploy as beans --> <context:component-scan base-package="com.loiane" /> <!-- Configures the @Controller programming model --> <mvc:annotation-driven /> <!-- misc --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="suffix" value=".jsp"/> </bean> <!-- Configures Hibernate - Database Config --> <import resource="db-config.xml" /> 你可以看到有上下文：component-scan和mvc：annotation-driven标签,它们应该告诉spring扫描com.lione包中@Controller注释的所有类.但是当我尝试将自己的控制器添加到此应用程序时,它似乎没有被处理.仅映射第一个控制器. 这是我的控制器代码 package com.loiane.web; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; @Controller public class HelloController { @RequestMapping("/helloWorld.action") public ModelAndView helloWorld() { ModelAndView mav = new ModelAndView(); mav.setViewName("helloWorld"); mav.addObject("message", "Hello World!"); return mav; } } 在eclipse控制台日志中运行后我得到了 INFO: Mapped URL path [/contact/delete.action] onto handler 'contactController' INFO: Mapped URL path [/contact/create.action] onto handler 'contactController' INFO: Mapped URL path [/contact/update.action] onto handler 'contactController' INFO: Mapped URL path [/contact/view.action] onto handler 'contactController' 但缺少/helloWorld.action 提前致谢

在使用< context：component-scan base-package =“package-name”/>时,有时候更好地了解您的路径是个好主意.所以你应该做< context：component-scan base-package =“com.loiane.web”/>
