第一个问题：
SSM框架整合中：出现错误：NoSuchBean（service层）
报错如下：
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.tmj.service.IUserService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
最后找到原因：没有整合Spring和SpringMVC，应在Web.xml中整合Spring：如下图：
代码也贴在这了：
<!-- 加载spring容器 --><context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
第二个问题：
SSM整合时，报500，如下：
严重: Servlet.service() for servlet [SpringMVC] in context with path [] threw exception [Request processing failed; nested exception is org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.tmj.mapper.UserMapper.getAll] with root cause
org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.tmj.mapper.UserMapper.getAll
最后发现原因是：Spring没有绑定好Mapper.xml文件；
解决办法：
把Mapper.xml放在classpath路径下，然后在Spring-Mybatis配置文件配置sqlsessionFactory的时候添了这一句：
<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
