构建ssm项目

创建maven的ssm项目

1、eclipse创建好maven项目。

2、导入ssm项目的jar包依赖。

3、在web项目的web.xml文件中配置Spring框架、SpringMVC框架

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
​
​
​
​
    <!-- 1.配置Listener 读取application.xml -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
​
    <!-- 2.Filter 配置编码格式 -->
    <filter>
        <filter-name>filter</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>filter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
​
    <!-- 3.Servlet 前端控制器 -->
    <servlet>
        <servlet-name>dispatcherServlet</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>
        <!-- <async-supported>true</async-supported> -->
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
​
    <!-- 默认静态资源映射 -->
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.jpg</url-pattern>
    </servlet-mapping>
    <servlet-mapping>

        <servlet-name>default</servlet-name>
        <url-pattern>*.png</url-pattern>
    </servlet-mapping>
​
</web-app>
​

4、spring框架的配置文件application.xml

<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:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:util="http://www.springframework.org/schema/util"
    xsi:schemaLocation="http://www.springframework.org/schema/beans

       http://www.springframework.org/schema/util 
       http://www.springframework.org/schema/util/spring-util-4.2.xsd">
 
 
     <!-- 配置组件扫描器 用来进行包扫描service层--> 
     <!--修改成你的包名 比如cn.gec.web.service-->
     <context:component-scan base-package="cn.test.bookms"/> 
       
    <!-- 读取db.properties -->
    <util:properties id="dbConfig"
        location="classpath:db.properties" />
        
    <!-- 配置数据源：BasicDataSource -->
    <bean id="ds" 
        class="org.apache.commons.dbcp.BasicDataSource">
        <!-- 以下配置中 -->
        <!-- name的值是BasicDataSource中的属性名(方法名) -->
        <!-- value的值是引用以上读取的配置文件 -->
        <property name="url" 
            value="#{dbConfig.url}" />
        <property name="driverClassName" 
            value="#{dbConfig.driver}" />

    </bean>
     
    <!-- 配置session工厂 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="ds"/>
        <!-- 自动扫描mappers.xml文件 -->
        <property name="mapperLocations" value="classpath:mappers/*.xml"></property>
        <!-- mybatis 总配置文件 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>
     
     <!-- Mapper扫描器 -->
     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 
        <!-- Mapper接口所在的包  改成你的包名：cn.gec.web.mapper-->
        <property name="basePackage" value="cn.test.bookms.mapper"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
     </bean>
     
     
    <!-- 事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

            <tx:method name="select*" read-only="true"/>
        </tx:attributes>
     </tx:advice>
      
     <!-- 配置AOP，为添加事务管理的操作配置AOP -->
    <aop:config>
        <!-- 引入的Spring定义的事务通知，需要使用aop:advisor -->
        <!--修改一下包名cn.gec.web.service-->
        <aop:advisor advice-ref="txAdvice"
            pointcut="execution(* cn.test.bookms.service.*.*(..))"
        />
    </aop:config> 
 
</beans>

5、springMVC配置文件spring-mvc.xml

<?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:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:task="http://www.springframework.org/schema/task"
    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
        http://www.springframework.org/schema/task
        http://www.springframework.org/schema/task/spring-task-4.2.xsd">
​
    <!-- 启动自动扫描 改成你的包名cn.gec.web.controller-->
    <context:component-scan
        base-package="cn.test.bookms.controller" />
​
    <!-- 注册MVC注解驱动 -->
    <mvc:annotation-driven />
​
    <!-- 静态资源可访问的设置方式 -->
    <mvc:default-servlet-handler />
​
​
    <!-- 视图解析器 -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 配置从项目根目录到指定目录一端路径 ,建议指定浅一点的目录 -->
        <property name="prefix" value="/WEB-INF/jsp/"></property>
        <!-- 文件的后缀名 -->
        <property name="suffix" value=".jsp"></property>
    </bean>
​
    <!-- 文件上传 -->
    <bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 设置默认编码 -->
        <property name="defaultEncoding" value="utf-8"></property>
        <!-- 上传图片最大大小5M -->
        <property name="maxUploadSize" value="5242440"></property>
    </bean>
</beans>
​

6、mybatis配置文件

<?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>
​
​
</configuration>

7、相应的配置文件

8、创建单元测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring/springmvc.xml", "classpath:spring/applicationContext.xml" })

\
