【问题经验】掉进spingaop的陷阱-aop导致controller私有requestmapping方法NPE异常
问题描述
环境：spring mvc 4.3.17
现象：org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.NullPointerException
描述：很早以前的老代码，以前同事没注意，某个Controller里面的RequestMapping方法用了private修饰(因为Spring是反射调用所以也能接受到请求)。最近，另一位同事针对这个Controller加了一段aop。测试环境自测就发现报NPE异常了。
代码现场：我模拟问题代码写了一段，首先是controller类文件，helloPri是private修饰的私有方法
@RestController
@RequestMapping("/focuse")
public class DemoController {
@Resource
private DemoPrinter demoPrinter;
@RequestMapping("hello")
public String hello(@RequestParam("text") String text) {
return demoPrinter.print(text);
}
@RequestMapping("hello_pri")
private String helloPri(@RequestParam("text") String text) {
return demoPrinter.print(text);
}
}其次是aop的配置，就是BeanNameAutoProxyCreator，(只是模拟问题代码现场，配置尽量简单了)
demoController
请求/focuse/hello_pri抛异常，请求/focuse/hello正常
原因分析
这个问题不容易看出来(火眼金睛能注意到前面的private)，我们是debug断点发现，当前对象并不是DemoContrller而是CGLIB生成的类，觉得有点奇怪。再对比一下没问题的请求，它的对象就是DemoController。

为什么会出现如此情况？ 那得看看spring容器在初始化bean的过程中何时初始化aop，生成动态代理类；又是何时自动设置依赖属性的。
Spring容器设置Bean的依赖属性、aop初始化都是通过BeanPostProcessor机制实现的。@Resource是通过CommonAnnotationBeanPostProcessor实现的，@Autowired、@Value是通过AutowiredAnnotationBeanPostProcessor实现的，BeanNameAutoProxyCreator本身就是BeanPostProcessor，这三个都是特殊的BeanPostProcessor（InstantiationAwareBeanPostProcessor）。
public interface InstantiationAwareBeanPostProcessor extends BeanPostProcessor {
......
PropertyValues postProcessPropertyValues(
PropertyValues pvs, PropertyDescriptor[] pds, Object bean, String beanName) throws BeansException;
......
}如上，InstantiationAwareBeanPostProcessor比常规的BeanPostProcess多几个方法(这里只列了跟这个问题相关的一个)，CommonAnnotationBeanPostProcessor和AutowiredAnnotationBeanPostProcessor就是在postProcessPropertyValues的实现方法中对bean的属性进行设置。
而BeanNameAutoProxyCreator是在postProcessAfterInitialization的实现方法中对bean进行动态代理。AbstractAutoProxyCreator是BeanNameAutoProxyCreator的父类，wrapIfNecessary方法就实现了对bean的动态代理。
public abstract class AbstractAutoProxyCreator extends ProxyProcessorSupport
implements SmartInstantiationAwareBeanPostProcessor, BeanFactoryAware {
......
@Override
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
if (bean != null) {
Object cacheKey = getCacheKey(bean.getClass(), beanName);
if (!this.earlyProxyReferences.contains(cacheKey)) {
return wrapIfNecessary(bean, beanName, cacheKey);
}
}
return bean;
}
......
}postProcessPropertyValues的执行时机要早于postProcessAfterInitialization，postProcessPropertyValues是在populateBean方法中执行，postProcessAfterInitialization在initializeBean中被调用到。
public abstract class AbstractAutowireCapableBeanFactory extends AbstractBeanFactory
implements AutowireCapableBeanFactory {
protected Object doCreateBean(final String beanName, final RootBeanDefinition mbd, final Object[] args)
throws BeanCreationException {
... ...
// Initialize the bean instance.
Object exposedObject = bean;
try {
populateBean(beanName, mbd, instanceWrapper);
if (exposedObject != null) {
exposedObject = initializeBean(beanName, exposedObject, mbd);
}
}
catch (Throwable ex) {
... ...
}
... ...
}
}就是说Spring容器在创建bean的过程先设置bean的依赖属性，然后对bean执行动态代理生成代理类对象并将代理类对象放到容器中。在本例中，我们来串一串DemoController这个对象bean的生成过程。
- 首先创建一个DemoContrller对象demoController(默认构造方法)，此时DemoController的属性demoPrinter为空；
- 对demoController执行populateBean方法，在populateBean方法中执行postProcessPropertyValues，设置demoPrinter属性，此时demoContrller对象中demoPrinter不为空(在创建DemoPrinter对象的时候也是走了一遍bean的创建初始化过程)；
- 对demoController执行initializeBean方法，在initializeBean方法中会调用AbstractAutoProxyCreator(BeanNameAutoProxyCreatord的父类)的postProcessAfterInitialization，这个方法对demoController生成代理类(DemoController$$EnhancerBySpringCGLIB$$5f7bd00.class)返回代理类对象demoControllerProxy(请注意代理对象demoControllerProxy是没有执行populateBean方法的，也就是说代理类对象里面的demoPrinter是空的)；
- Spring容器拿到代理类对象demoControllerProxy后，将代理类对象demoControllerProxy放入容器，供以后单例获取bean使用
那么mvc在获取requestmapping的handler对象实际是代理类对象demoControllerProxy。因为DemoController是类不是接口，所以动态代理采用的是cglib组件，我们知道cglib组件是不会对private方法生成代理方法的。也就是说代理类对DemoController#hello生成了代理方法，调用代理类对象的hello最终调用到被代理对象(demoController)的hello方法；而DemoController#helloPri则没有生成代理方法，调用代理类对象的helloPri就是调用代理类的helloPri。第3步明确了代理类对象没有执行populateBean方法，所以代理类对象的demoPrinter是null，所以就抛了NPE异常。
至此，NPE异常原因分析完了。
如何避免
- 代码规范：private、public不要瞎用
- 改掉ctrl-c ctrl-v的习惯，尤其大段大段的复制粘贴
后记：本例给的aop是用BeanNameAutoProxyCreator方式配置的，其实用
最后贴一下cglib组件对DemoController生成的代理类文件(DemoController子类且没有对helloPri生成代理方法)：
