spring-mybatis.xml   

配置是一直數據庫連接不上  找到錯誤  db.properties    文件配置錯誤導致鏈接不上數據庫

<!--引入配置文件-->
    <bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:db.properties" />
    </bean>
    <!--鏈接數據庫   數據源-->
    <bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="${driver}"></property>
        <property name="url" value="${url}"></property>
        <property name="username" value="${username}"></property>
        <property name="password" value="${password}"></property>
    </bean>
    <!--mapper讀取-->
    <bean id="splSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="mapperLocations" value="classpath:Mapper/*.xml"/>
    </bean>

    <!--dao接口所在位置-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="come.one.dao"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>

@Controller 註解無法添加    因爲再加入jar包是添加如下問題

<dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.1</version>
            <scope>runtime</scope>
            <classifier />
        </dependency>

因爲maven 中cope對項目jar有限制  具體參見點擊打開鏈接
