类 BeanMethodInterceptorChain

java.lang.Object

network.nerve.core.core.inteceptor.base.BeanMethodInterceptorChain

直接已知子类:

MultipleBeanMethodInterceptorChain

public class BeanMethodInterceptorChain
extends Object

方法拦截器链：一个方法可以被多个拦截器拦截，多个拦截器之间顺序的组成了一条拦截器链，没个拦截器可以决定是否继续执行后面拦截器 Method the interceptor chain: one method can be more interceptors to intercept, between multiple interceptors sequence formed a chain of interceptors, behind each blocker can decide whether to continue the interceptor

add

protected void add(BeanMethodInterceptor interceptor)

像链中添加一个方法拦截器 Add a method interceptor to the chain.

参数:

interceptor - 拦截器

startInterceptor

public Object startInterceptor(Annotation annotation,
                               Object object,
                               Method method,
                               Object[] params,
                               net.sf.cglib.proxy.MethodProxy methodProxy)
                        throws Throwable

将一个方法放入该拦截器链中执行，获取返回结果 Puts a method in the interceptor chain to retrieve the returned result.

参数:

annotation - 拦截方法的注解实例/Annotation instances of the intercepting method.

object - 方法所属对象/Method owner

method - 方法定义/Method definition

params - 方法参数列表/Method parameter list

methodProxy - 方法代理器

返回:

返回拦截的方法的返回值，可以对该值进行处理和替换/Returns the return value of the intercepting method, which can be processed and replaced.

抛出:

Throwable - 该方法可能抛出异常，请谨慎处理/This method may throw an exception, handle with care.

execute
