修改serviceImpl为:
@Autowired(required=false)
private UserMapper userM
不报错了,但userMapper为null,也不注入了,这样解决虽然不报错了,但项目无法继续进行,所以另寻方法。
各种解决办法都试了后,没解决,所以就自己在重新看看自己的项目。
我的错误原因在:web.xml启动是没加载soring-mybatis.xml,加上以后问题解决。
我的这个原因在于web.xml没有加载,仅是问题一种。可以看看你的是否加载,如果加载了就去看看其他原因吧!
可以运行的配置:

Spring/SpringMVC（7）
mybatis/ibatis（3）
整合springmvc和mybatis时，启动服务报错如下：
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [demo.dao.PersonMapper] 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)}
错误重点挑出来：
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [demo.dao.PersonMapper] found for dependency
PersonMapper这个接口的实现对象没有注入！
我的servicer接口实现类代码：
@Service("personService")
public class PersonServiceImpl implements IPersonService {
@Autowired
private PersonMapper personM
public Person queryById(Integer id) {
return this.personMapper.selectByPrimaryKey(id);
启动时这一段代码中@Autowired
personMapper引起错误的，没有在容器中找到对象。
可能出现错误的原因：
1、没有在配置文件中添加如下注解配置：（我添加了）
base-package="demo.*" /&
2、那么是不是配置文件错误导致文件没有加载，从而引起没有注解进来。于是我把代码改成了下段代码：
@Service("personService")
public class PersonServiceImpl implements IPersonService {
private PersonMapper personM
public Person queryById(Integer id) {
ApplicationContext
ac = new ClassPathXmlApplicationContext("classpath:application/applicationContext-datasource.xml");
personMapper = (PersonMapper) ac.getBean("personMapper");
return this.personMapper.selectByPrimaryKey(id);
ok，可以运行，说明配置文件没有问题。
那么之前那样是不是根本没有加载applicationContext-datasource.xml文件，于是我在jdbc.properties文件中改了一个key值（xml文件中引用了），然后把service实现类中的有关代码删除，启动看是否报错，如果报错说明加载了xml文件，如果不报错说明没有加载文件。结果木有报错！！！
于是得出木有加载applicationContext-datasource.xml文件！
下面是我的web.xml配置：
&contextConfigLocation&
classpath*:application/applicationContext*.xml
下面是我的数据库mybatis相关配置：
id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"&
name="dataSource" ref="defaultDataSource" /&
name="mapperLocations" value="classpath:mapper/*.xml"&&
class="org.mybatis.spring.mapper.MapperScannerConfigurer"&
name="basePackage" value="demo.dao" /&
name="sqlSessionFactoryBeanName" value="sqlSessionFactory"&&
id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager"&
name="dataSource" ref="defaultDataSource" /&
仔细考察这两个配置，觉得没啥问题，然后看到web.xml中contextConfigLocation这个是怎么加载指定的配置文件的，然后百度了，解决方法：
在web.xml中添加上下文监听器
&org.springframework.web.context.ContextLoaderListener&
关于contextConfigLocation了解点击：

Spring搭建开发环境实例详解（5）
SpringMVC（5）
Spring（7）
好久不搭架构，今天使用spring+springmvc整合mabytis的时候，坑爹的两个问题发生了。
花了一晚上解决这两个问题。现在将错误经验总结分享下，避免以后遇到坑继续往里跳。

执行单元测试的时候，报错了警告: Exception encountered during context initialization - cancelling refresh attempt

这时候去检查spring-core和springMVC的两个配置文件，异常提示信息大意是ServletContext需要配置默认servlet处理映射器。一脸懵逼。。。最后发现是两个配置文件的context和包扫描配置有问题，springServlet上下文应该在spring核心配置中( spring_ynyn_dependence.xml )处理，需要使用 &context:annotation-config /& 进行配置。调整后的配置是：
1.sprin框架的配置文件spring_ynyn_dependence.xml调整
将以下配置内容
&context:component-scan base-package="org.byron4j.ynyn.*" &
&context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /&
&/context:component-scan&
&context:annotation-config /&
2.springMVC的配置文件spring-mvc.xml调整
&context:component-scan base-package="com.crfchina.mcp.*" &
&context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /&
&/context:component-scan&
再次执行单元测试，OK。

解决第一个问题，单元测试后，部署该项目启动时，疯狂报错nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.byron4j.mcp.mapper.TaskerMapper] 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)}。多次检查，发现springMVC配置文件中也需要加载mybatis配置，前面我仅仅在spring上下文核心配置文件(spring_ynyn_dependence.xml)中做了配置。
在spring-mvc.xml文件最后引入加载mybatis配置：
resource="classpath*:byron4j_ynyn_datasource.xml"/&
重新部署应用启动服务无措，发起请求验证OK。
