ssm项目的简单搭建

项目的结构如图

首先在pom文件中添加依赖,都是最基本的jar包

<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/maven-v4_0_0.xsd">

      <artifactId>commons-dbcp</artifactId>
      <version>1.4</version>
    </dependency>
    <!--javax servlet-->
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>

    </dependency>



  </dependencies>
  <build>
    <finalName>spring-test</finalName>
  </build>
</project>

在项目的resource文件夹中创建spring-mvc.xml和spring-mybatis.xml文件
然后在项目的web.xml文件中添加

<!DOCTYPE web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_3_0.dtd" >

<web-app>
    <display-name>Archetype Created Web Application</display-name>
    <!--配置页面和服务器传递参数的编码-->
    <filter>
        <filter-name>CharacterEncoding</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>CharacterEncoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-mybatis.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.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>

然后是我们刚才创建的spring-mvc.xml文件中

<?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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--开启spring默认servlet访问注解 -->
    <mvc:annotation-driven></mvc:annotation-driven>
   <!-- 对静态资源文件的访问  加入这个必须添加上annotation-driven-->
   <mvc:default-servlet-handler></mvc:default-servlet-handler>
   <!--实现自动扫描注解-->
   <context:component-scan base-package="这里写要扫描的注解包"/>
    <!--s实现spring的试图管理 使用的是国际试图-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/jsp/"></property>
        <property name="suffix" value=".jsp"></property>
     </bean>
</beans>

然后在spring-mybatis.xml文件中填写

<?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:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/tx   http://www.springframework.org/schema/tx/spring-tx.xsd
">
    <!--创建连接数据库的连接池-->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url" value="jdbc:mysql://localhost:3306/sopping?serverTimezone=UTC&amp;characterEncoding=utf-8"></property>
        <property name="username" value="root"></property>
        <property name="password" value="chen"></property>
    </bean>



    <!--创建mapper.xml文件的扫描-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--这里一定要使用ref 找到的是响应的bean-->
        <property name="dataSource" ref="dataSource"></property>
        <property name="mapperLocations" value="classpath:mapper.xml文件路径(com/chen/mapper/*.xml)"></property>
    </bean>
    <!--未mapper类注入sqlSessionFactory-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--这里要使用value-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
        <property name="basePackage" value="这里写的是mapper类的包路径(com.chen.mapper)"></property>
    </bean>
</beans>

现在这个项目就能跑起来了,创建的jsp文件放在webContent文件夹下的jsp文件夹中
