Aop拦截到的Action 使得@Autowired 无法自动装配问题解决 (一)

对Struts1/2 Action应用Spring AOP问题小结
之前使用SSH三大经典框架的时候，写了一个简单的统计Action每个方法执行时间的功能类，代码如下：
[java]
import javax.servlet.http.HttpServletRequest;

import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;
import org.apache.commons.lang.StringUtils;
import org.apache.commons.lang.time.StopWatch;
import org.apache.struts.actions.DispatchAction;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;
import org.springframework.aop.framework.ReflectiveMethodInvocation;

/**
* 统计方法执行时间的拦截器,采用Spring AOP方式实现.
*
* @author Kanine
*/
@Service("runTimeHandler")
public class RunTimeHandler implements MethodInterceptor {

private static Logger logger = LoggerFactory.getLogger("code.coolbaby");

@SuppressWarnings("unchecked")
public Object invoke(MethodInvocation methodInvocation) throws Throwable {

Object[] args = methodInvocation.getArguments();
String method = methodInvocation.getMethod().getName();
String action = methodInvocation.getMethod().getDeclaringClass().getName();

/**
* 由于Spring使用了Cglib代理,导致不能直接取得目标类名,需作此转换
*/
if (methodInvocation instanceof ReflectiveMethodInvocation) {
Object proxy = ((ReflectiveMethodInvocation) methodInvocation).getProxy();
action = StringUtils.substringBefore(proxy.toString(), "@");
/**
* 如使用了DispatchAction,将不能直接取得目标方法,需作此处理
*/
if (proxy instanceof DispatchAction) {
for (Object arg : args) {
if (arg instanceof HttpServletRequest)
method = ((HttpServletRequest) arg).getParameter("method");
}
}
}

/**
* 方法参数类型，转换成简单类型
*/
Class[] params = methodInvocation.getMethod().getParameterTypes();
String[] simpleParams = new String[params.length];
for (int i = 0; i < params.length; i++) {
simpleParams[i] = params[i].getSimpleName();
}

String simpleMethod = method + "(" + StringUtils.join(simpleParams, ",") + ")";

logger.info("{} 开始执行[{}]方法", action, method);

StopWatch clock = new StopWatch();
clock.start();
Object result = methodInvocation.proceed();
clock.stop();

logger.info("执行[{}]方法共消耗{}毫秒", simpleMethod, clock.getTime());

return result;
}
}
