没有用于处理程序的适配器-DispatcherServlet配置需要包括一个支持该处理程序的HandlerAdapter

Question

我要将Spring 3迁移到Spring 4，因此请使用以下配置： dispatcher-servlet.xml->

<beans>
    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>                
                <prop key="Transaction/*.do">TransactionController</prop>
</props></property></bean>

控制器类->

@Controller
public class TransactionController {

applicationContext.xml->

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
    http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"> 
     <bean
        class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
    <context:annotation-config />
    <mvc:annotation-driven />
    <context:component-scan base-package="com.controller" />

在运行应用程序时，我遇到以下错误：

javax.servlet.ServletException: No adapter for handler [com.controller.transaction.TransactionController@6632ab18]: The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler
    at org.springframework.web.servlet.DispatcherServlet.getHandlerAdapter(DispatcherServlet.java:1202)
    at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:947)

我也尝试了The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler中给出的方法，但仍然遇到问题。
