我的任务
分享spring注入，空指针异常，看了好多帖子忍找不到办法，求大神指点
以下是我自己做的例子：使用全注解的形式
DAO层：
package Impl.DAOImpl;
import javax.annotation.Resource;
import org.springframework.stereotype.Repository;
import DAO.RegionDAO;
import Entity.Region;
@Repository(value="regionDAOimpl")
public class RegionDAOImpl implements RegionDAO {
@Resource
private RegionDAO regionmapper;
public RegionDAO getRegionmapper() {
return regionmapper;
}
/*public void setRegionmapper(RegionDAO regionmapper) {
this.regionmapper = regionmapper;
}*/
public Region selectRegion(int code) {
return regionmapper.selectRegion(code);
}
public int updateRegion(int code) {
return regionmapper.updateRegion(code);
}
public void deleteRegion(int code) {
regionmapper.deleteRegion(code);
}
public int insertRegion(Region region) {
return regionmapper.insertRegion(region);
}
public void test2() {
System.out.println("test2");
}
}

楼主这个问题是怎么解决的哇?求指导

搞了两天，终于弄完了，分享下我的经验：
导致spring注入失败的原因可能是（我自己这方面是这样）：
web.xml配置文件中：
<servlet-class>一项原先配置是：
com.sun.jersey.spi.container.servlet.ServletContainer
后来参考（之前没注意，该文结尾作者醒目的提示）http://www.cnblogs.com/qunyang/p/3328561.html将<servlet-class>一项改成：com.sun.jersey.spi.spring.container.servlet.SpringServlet
除此之外，导包也需要注意，不过这一点应该对大家不是问题，遇到错误，google就能找到
第三个提醒就是：mybatis框架配置中的映射文件配置中mapper namespace要和定义的接口名称一致
结尾：谢谢斑竹和各位的大力支持，要不是你们提醒我做个test，我也不会慢慢刨出问题，另外，以后我提问也要注意下排版细节，再次谢过！

空指针
at Impl.ServiceImpl.RegionServiceImpl.findRegion(RegionServiceImpl.java:51)
RegionServiceImpl 51行都做了什么操作呢？（你的代码没有排版，看不出行数）

org.apache.ibatis.binding.BindingException产生这个异常原因找到了，原来是mapper namespace的名称和interface的名称不一致，这个是我参考的网址：http://blog.csdn.net/zgmzyr/article/details/8044980
但是最根本的异常还是存在：
下面是异常信息：
10
true

用的是mybatis

另外：我在spring的配置里配置了：
<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" />，因为之前没有红色标注的那部分，总是说找不到bean，但是删掉每个方法上的@transaction注解后就能找到，所以我到网上找了一些资料，添加了红色那部分，但我不知道这个添加会不会对现在产生的异常有影响，希望大神们了解这一点

后台是用Hibernate吗？

补充：
mybatis里不是有个映射文件嘛，在这里我把RegionDAO就当成mapper接口，在applicationContext.xml里已经配置了
<bean id="regionmapper" class="org.mybatis.spring.mapper.MapperFactoryBean" >
<property name="sqlSessionFactory" ref="sqlSessionFactory"/>
<property name="mapperInterface" value="DAO.RegionDAO"/>
</bean>
，另外我也在那个test类里测试了，代码如下：
ApplicationContext appContext = new
ClassPathXmlApplicationContext("applicationContext.xml");
//System.out.println(appContext.getType("regionServiceimpl"));
RegionServiceImpl regionService = (RegionServiceImpl)appContext
.getBean(RegionServiceImpl.class);
regionService.test();
Region region = regionService.findRegion("110101");
System.out.println(region.getName());
异常产生了：

再测试下增删改查的功能，看下是不是一样的错。

你前面的定义：
@Repository(value="regionDAOimpl")
public class RegionDAOImpl implements RegionDAO {
@Resource
private RegionDAO regionmapper;
感觉应该是这个regionmapper的问题。
那个测试类调用test方法没用到增删改查，因此没报错。
你具体错误日志是啥呢？
