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">  <modelVersion>4.0.0</modelVersion>  <groupId>com.chen</groupId>  <artifactId>spring-test</artifactId>  <packaging>war</packaging>  <version>1.0-SNAPSHOT</version>  <name>spring-test Maven Webapp</name>  <url>http://maven.apache.org</url>  <properties>    <spring.version>4.3.6.RELEASE</spring.version>  </properties>  <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-core</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-beans</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-web</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-jdbc</artifactId>      <version>${spring.version}</version>    </dependency>      <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis</artifactId>      <version>3.4.2</version>    </dependency>    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis-spring</artifactId>      <version>1.3.1</version>    </dependency>    <dependency>      <groupId>mysql</groupId>      <artifactId>mysql-connector-java</artifactId>      <version>6.0.5</version>    </dependency>    <!--dbcp -->    <dependency>      <groupId>commons-dbcp</groupId>      <artifactId>commons-dbcp</artifactId>      <version>1.4</version>    </dependency>    <!--javax servlet-->    <dependency>      <groupId>javax.servlet</groupId>      <artifactId>javax.servlet-api</artifactId>      <version>3.1.0</version>    </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
