配置是一直数据库连接不上  找到错误  db.properties    文件配置错误导致链接不上数据库

<!--引入配置文件-->
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:db.properties" />
</bean>
<!--链接数据库 数据源-->
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${driver}"></property>
<property name="url" value="${url}"></property&
4000

<property name="username" value="${username}"></property>
<property name="password" value="${password}"></property>
</bean>
<!--mapper读取-->
<bean id="splSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mapperLocations" value="classpath:Mapper/*.xml"/>

<!--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 注解无法添加    因为再加入jar包是添加如下问题
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
<scope>runtime</scope>
<classifier />
</dependency>因为maven 中cope对项目jar有限制  具体参见点击打开链接

spring-mvc.xml
<!-- 可以扫描controller、service、...
这里让扫描controller，指定controller的包
-->

<!--注解映射器 -->
<!-- <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/> -->
<!--注解适配器 -->
<!-- <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/> -->

<!-- 使用 mvc:annotation-driven代替上边注解映射器和注解适配器配置
mvc:annotation-driven默认加载很多的参数绑定方法，
比如json转换解析器就默认加载了，如果使用mvc:annotation-driven不用配置上边的RequestMappingHandlerMapping和RequestMappingHandlerAdapter
实际开发时使用mvc:annotation-driven
-->
<!-- <mvc:annotation-driven conversion-service="conversionService"></mvc:annotation-driven> -->

第二种: /. 所有访问的地址都由DispatcherServlet进行解析，对于静态文件的解析需要配置不让DispatcherServlet进行解析
第三种: /* 这种配置不对，使用这种配置，最终要转发到一个jsp页面时,仍然会由DispatcherServlet解析jsp地址，不能根据jsp页面找到handler，会报错
