一、项目创建：

1、创建一个Javaweb项目并且配置好tomcat等

（之前做过 此步省略）

2、在setting中引入MAVEN

 注意：

MAVEN 的版本不能早于编辑器的版本否则会报错。

3、创建项目结构

二、代码编写：

修改pom.xml文件，导入需要的包：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

（1）连接数据库配置信息文件：db.properties

druid.driver=com.mysql.jdbc.Driver
druid.url=jdbc:mysql://localhost:3306/all_db?characterEncoding=utf-8
druid.username=root
druid.password=Guozhaojie610

（2）Mybatis配置文件：SqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>
    <!-- 给实体类起别名 -->
    <typeAliases >
        <package name="com.xiao.pojo"/>
    </typeAliases>

</configuration>

（3）Spring配置文件：applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
                        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
                        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">

    <!-- 配置扫描注解  @Controller @Service -->
    <context:component-scan base-package="com" />

    <!-- SpringMVC使用<mvc:annotation-driven>自动加载RequestMappingHandlerMapping和RequestMappingHandlerAdapter -->
    <mvc:annotation-driven />

    <!-- 配置静态资源映射 -->

    <mvc:resources location="/js/" mapping="/js/**"/>
    <mvc:resources location="/css/" mapping="/css/**"/>
    <mvc:resources location="/images/" mapping="/images/**"/>
    <mvc:resources location="/img_source/" mapping="/img_source/**"/>
    <mvc:resources location="/ueditor/" mapping="/ueditor/**"/>
    <mvc:resources location="/utilLib/" mapping="/utilLib/**"/>

    <!-- 配置视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 配置逻辑视图的前缀 -->
        <property name="prefix" value="/WEB-INF/jsp/" />
        <!-- 配置逻辑视图的后缀 -->
        <property name="suffix" value=".jsp" />

    </bean>

</beans>

最后需要在web.xml文件中进行配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
          http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">

  <display-name>SSM</display-name>

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

  <!-- spring监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- 指定spring核心配置文件 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <!-- 处理POST提交乱码问题 -->
  <filter>
    <filter-name>encoding</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>encoding</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- 配置前端控制器 -->
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 指定配置文件位置和名称 如果不设置,默认找/WEB-INF/<servlet-name>-servlet.xml -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

三、效果展示：

1、新闻首页

2、登录界面

3、后台添加新闻

4、新闻管理
