ssm整合之编写SpringMVC框架

1.在webapp/WEB-INF/web.xml配置的代码如下：

<!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>

2.在resources目录创建springmvc.xml的代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

    <!--开启注解扫描，只扫描Controller注解-->
    <context:component-scan base-package="com.txw">
        <!--只扫描这个注解-->
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>
    <!--配置的视图解析器对象-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--前缀-->
        <property name="prefix" value="/WEB-INF/pages/"/>
        <!--后缀-->
        <property name="suffix" value=".jsp"/>
    </bean>
    <!--过滤静态资源-->
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/images/" mapping="/images/**" />
    <mvc:resources location="/js/" mapping="/js/**" />
    <!--开启SpringMVC注解的支持-->
    <mvc:annotation-driven/>
</beans>

3.编写index.jsp的代码如下：

<%--
  Created by IntelliJ IDEA.
  User: Adair
  Date: 2020/7/8 0008
  Time: 14:26
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>首页</title>
</head>
<body>
    <a href="account/findAll">测试</a>
</body>
</html>

4.编写帐户的控制类的代码如下：

package com.txw.controller;

import org.springframework.stereotype.Controller;
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 {
    
    
    @RequestMapping(value = "/findAll")
    public String findAll(){
    
    
        System.out.println("表现层：查询所有账户...");
        return "list";
    }
}

5.在WEB-INF目录下创建pages目录，并创建list.xml的代码如下：

<%--
  Created by IntelliJ IDEA.
  User: Adair
  Date: 2020/7/8 0008
  Time: 14:35
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h3>查询所有的帐户</h3>
</body>
</html>

6.部署ssm服务器如图所示：在这里插入图片描述
