console: 日志為
2016-04-08 15:21:47 Looking up handler method for path /welcome
2016-04-08 15:21:47 Did not find handler method for [/welcome]
2016-04-08 15:21:47 No mapping found for HTTP request with URI [/springMVC/welcome] in DispatcherServlet with name 'spring'

解決方法：
解決1：
<mvc:annotation-driven/>
<context:component-scan base-package="com.mvc.rest/*"></context:component-scan>
改為
<mvc:annotation-driven/>
<context:component-scan base-package="com.mvc.rest"></context:component-scan>
去掉/*
解決2：
或者改為
<mvc:annotation-driven/>
<context:component-scan base-package="com.mvc.*"></context:component-scan>
原因component-scan base-package配置的是路徑名稱
如 value='com.mvc.rest' 則 掃描這個包路徑下的java bean, 如果配置的 com.mvc.* 則掃描com.mvc包下的子包， 如果是com.mvc.rest.*則掃描com.mvc.rest
下所有的子包，因為com.mvc.rest沒有子包，所以此處顯示“Did not find handler method for”日志
如果以上方法沒有解決問題，可以嘗試如下：
springmvc.xml文件是這樣的
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/jsps/user/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
spring.xml文件中內容這樣寫的
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"

<!-- 加載屬性配置文件 -->

<!-- 配置數據源 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<property name="driverClassName" value="${jdbc.driverClass}"/>
<property name="url" value="${jdbc.jdbcUrl}"/>
<property name="username" value="${jdbc.user}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
<!-- 配置sqlsessionfactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"/>
</bean>
<!-- 事務管理 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 配置通知 -->
<tx:advice id="txAdvicer" transaction-manager="transactionManager">

<tx:method name="find*" propagation="REQUIRED"/>
<tx:method name="get*" propagation="REQUIRED"/>
<tx:method name="save*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="insert*" propagation="REQUIRED"/>
<tx:method name="delete*" propagation="REQUIRED"/>
<tx:method name="*" propagation="REQUIRED"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:advisor advice-ref="txAdvicer" pointcut="execution(* com.hs.service.*.*(..))"/>
</aop:config>
<!-- 打開全局注解掃描qi -->
<!-- 批量配置mapper接口dao -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.hs.dao"/>
<!-- <property name="sqlSessionFactory" ref="sqlSessionFactory"/> -->
</bean>
</beans>
其實就是一個掃描的配置寫錯了位置
<context:component-scan base-package="com.hs"/>
這行配置時必須要寫在springmvc.xml文件中，因為加載該文件時，會掃描所有的加注解的controller，這樣RequestMappingHandlerMapping才會找到這個對象
