1.解决方法如图所示： 2.修改web.xml的代码如下：
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Archetype Created Web Application</display-name> <!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--设置配置文件的路径--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!--配置前端控制器--> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--加载springmvc.xml配置文件--> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <!--启动服务器，创建该servlet--> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--解决中文乱码的过滤器--> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>3.修改帐户的控制类代码如下：
package com.txw.controller; import com.txw.service.AccountService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; /** *帐户的控制类 * @author Adair */ @Controller @RequestMapping(path = "/account") @SuppressWarnings("all") // 注解警告信息 public class AccountController { @Autowired // 自动类型注入 private AccountService accountService; @RequestMapping(value = "/findAll") public String findAll(Model model){ System.out.println("表现层：查询所有账户..."); // 调用findAll()方法 accountService.findAll(); return "list"; } }4.重新部署项目运行结果如图所示：5.通过浏览器访问http://localhost:8080/如图所示：6.点击测试会跳转到如图所示的界面：7.控制台打印结果如图所示：证明Spring整合SpringMVC成功！
