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>

</dependency>
<!--javax servlet-->

</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&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
