java - Spring Framework 中 index.jsp 的 404 和其他页面的 UnsatisfiedDependencyException

Question

我在Spring Recipes 一章 Spring Security中编写了一个 Spring 中的 Web 项目。
我无法打开 index.jsp 或我创建的任何其他页面。

web.xml 的内容

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
        http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/board-service.xml
       </param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListner</listener-class>
    </listener>

    <servlet>
        <servlet-name>board</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>board</servlet-name>
        <url-pattern>*.htm</url-pattern>
    </servlet-mapping>
</web-app>

但是如果我删除<listner>标签，我可以查看 index.jsp，但我会看到org.springframework.beans.factory.UnsatisfiedDependencyException其他页面（messageList.htm）

Unsatisfied dependency expressed through constructor argument with index 0 of type [net.myclass.web.service.MessageBoardService]: : No qualifying bean of type [net.myclass.web.service.MessageBoardService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [net.myclass.web.service.MessageBoardService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

错误在页面 MessageDeleteController.java

@Controller
@RequestMapping("/messageDelete*")
public class MessageDeleteController {

    private MessageBoardService messageBoardService;

    @Autowired
    public MessageDeleteController(MessageBoardService messageBoardService)
    {
        this.messageBoardService=messageBoardService;
    }

    @RequestMapping(method=RequestMethod.GET)
    public String messageDelete(@RequestParam(required=true,value="messageId") Long messageId, Model model)
    {
        Message message=messageBoardService.findMessageById(messageId);
        messageBoardService.deleteMessage(message);
        model.addAttribute("messages",messageBoardService.listMessages());
        return "redirect:messageList";
    }

}

板服务.xml

<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

    <tx:annotation-driven/>
<bean id="messageBoardService" class="net.myclass.web.service.MessageBoardServiceImpl"/>
</beans>

MessageBoardServiceImpl 实现 MessageBoardService board-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"

Answer 1

But If I remove the <listner> tag, I am able to view the index.jsp 

那只是因为 Spring 不工作而你导航到 jsp

将您的控制器更改为此

private MessageBoardService messageBoardService;

@Autowired
public void setMessageBoardService(MessageBoardService messageBoardService)
{
    this.messageBoardService=messageBoardService;
}
