ssm整合之Spring整合SpringMVC的框架

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！
