• idea通过maven构建springMVC+mybatis项目


    1.用idea构建maven-archetype-webapp类型的项目

    2.完善目录,增加重要的source Folder,这个不是简单的Floder,这些文件夹是会参与编译的。增加src/main/java,src/test/resources,src/test/java目录。让目录变成标准的maven结构,如图。

    3.在pom文件中增加依赖包

    4.创建web开发常用的包结构,如图

    3.创建springMVC分发器配置文件,在resources下创建dispatcher-servlet.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"
           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 ">
    
        <!-- 启用spring mvc 注解 -->
        <mvc:annotation-driven />
    
        <!-- 设置注解的类所在的包-->
        <context:component-scan base-package="com.seari.controller" />
    
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/views/" />
            <property name="suffix" value=".jsp" />
        </bean>
    </beans>

    5.编辑jdbc配置文件,在resources下创建jdbc.properties

    jdbc_driverClassName=com.mysql.jdbc.Driver
    jbdc_url=jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=utf-8
    jdbc_username=root
    jdbc_password=root

    6.编辑spring-mybatis合成配置文件,在resources下创建spring-mybatis.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:context="http://www.springframework.org/schema/context"
           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">
    
        <!-- 引入JDBC文件 -->
        <context:property-placeholder location="classpath:conf/jdbc.properties" />
    
        <!-- 配置数据源 -->
        <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
            <property name="driverClassName">
                <value>${jdbc_driverClassName}</value>
            </property>
            <property name="url">
                <value>${jbdc_url}</value>
            </property>
            <property name="username">
                <value>${jdbc_username}</value>
            </property>
            <property name="password">
                <value>${jdbc_password}</value>
            </property>
    
            <!-- 连接池最大连接数 -->
            <property name="maxActive">
                <value>20</value>
            </property>
    
            <!-- 初始化连接大小 -->
            <property name="initialSize">
                <value>1</value>
            </property>
    
            <!-- 获取连接最大等待时间 -->
            <property name="maxWait">
                <value>60000</value>
            </property>
    
            <!-- 连接池最大和最小空闲 -->
            <property name="maxIdle">
                <value>20</value>
            </property>
            <property name="minIdle">
                <value>3</value>
            </property>
    
            <!-- 自动清除无用连接 -->
            <property name="removeAbandoned">
                <value>true</value>
            </property>
    
            <!-- 清除无用连接的等待时间 -->
            <property name="removeAbandonedTimeout">
                <value>180</value>
            </property>
    
            <!-- 连接属性 -->
            <property name="connectionProperties">
                <value>clientEncoding=UTF-8</value>
            </property>
        </bean>
    
        <!-- 扫描文件(自动将service层注入) -->
        <context:component-scan base-package="com.seari.service" />
    
        <!-- mybatis文件配置,扫描所有mapper文件 -->
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource" />
        </bean>
    
        <!-- spring与mybatis整合配置,扫描所有的mapper -->
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="basePackage" value="com.seari.mapper"/>
            <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
        </bean>
    
        <!-- 对数据源进行事务管理 -->
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"/>
        </bean>
    </beans>

    注:这里没有指明java源代码目录mapper包下接口对应的mapper.xml文件,所以会用默认的路径,即跟mapper类对应的文件下,在resources下新建跟mapper类相同的路径,如图:

    7.编辑web.xml

    <?xml version="1.0" encoding="UTF-8"?>
    
    <web-app version="2.5"
            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">
        <display-name>Archetype Created Web Application</display-name>
    
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:conf/spring-mybatis.xml</param-value>
        </context-param>
    
        <!-- 字符集过滤器 -->
        <filter>
            <filter-name>CharacterEncodingFilter</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>
            <init-param>
                <param-name>forceEncoding</param-name>
                <param-value>true</param-value>
            </init-param>
        </filter>
        <filter-mapping>
            <filter-name>CharacterEncodingFilter</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>
        
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
        <!-- SpringMVC 分发器 -->
        <servlet>
            <servlet-name>dispatcher</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>classpath:conf/dispatcher-servlet.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>dispatcher</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    
        <welcome-file-list>
            <welcome-file>index</welcome-file>
        </welcome-file-list>
    </web-app>

    8.编写测试相关类文件和页面测试
