Spring整合Mybatis错误

最近几天闲来无事，做了Spring和Mybatis注解整合（Maven项目），虽然很难，一路走来很开心

项目整合地址：http://yudey.iteye.com/admin/blogs/1986446

直接看错误，然后再讲解决方法，欢迎大家补充

我承认错误比较多，看的眼花缭乱的
其实总结起来就2中错误
1.Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0'
2. No matching bean of type [com.mxy.service.AccountService] found for dependency

解决方法：(欢迎大家补充)
第一种情况：（网上找的解决方法）我当时就是这种情况
i think it comes from this line in your XML file:

<context:component-scan base-package="com.mxy.controller" />

Replace it by:

<context:component-scan base-package="com.mxy" />

第二种情况： 注入映射器
添加如下配置到Mybatis配置文件中，这种配置比较繁琐，每个接口都要配置下

<bean id="accountMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
	  <property name="mapperInterface" value="com.mxy.mapper.AccountMapper" />
	  <property name="sqlSessionFactory" ref="sqlSessionFactory" />
	</bean>

或者添加下面的内容。这个方法比较爽，一劳永逸

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.mxy.mapper" />
	</bean>

第三种情况：在serviceImpl中要类上要添加@Service

@Service
public class BaseServiceImpl implements AccountService {

第四种情况：
