aop切面管理统一接口类：
（1）spring配置：
被切面监控的类需要放在pointcut的配置的路径下；
<!-- AOP配置 --> <aop:config> <!-- 声明一个切面,并注入切面Bean,相当于@Aspect --> <aop:aspect id="httpInterceptor" ref="httpInterceptor"> <!-- 配置通知,相当于@Before、@After、@AfterReturn、@Around、@AfterThrowing --> <aop:around pointcut="execution(public * com.jd.worldwide.http.service.c2c..*.*(..))" method="aroundMethod" /> <aop:around pointcut="execution(public * com.jd.worldwide.http.service.interAuth.inner..*.*(..))" method="aroundMethod" /> <aop:around pointcut="execution(public * com.jd.worldwide.http.service.faq..*.*(..))" method="aroundMethod" /> <aop:around pointcut="execution(public * com.jd.worldwide.http.service.advert..*.*(..))" method="aroundMethod" /> </aop:aspect> <aop:aspect id="jsfInterceptor" ref="jsfInterceptor"> <!-- 配置通知,相当于@Before、@After、@AfterReturn、@Around、@AfterThrowing --> <aop:around pointcut="execution(public * com.jd.worldwide.jsf.service.c2c..*.*(..))" method="aroundMethod" /> <aop:around pointcut="execution(public * com.jd.worldwide.jsf.service.clearance..*.*(..))" method="aroundMethod" /> <aop:around pointcut="execution(public * com.jd.worldwide.jsf.service.detailPage..*.*(..))" method="aroundMethod" /> <aop:around pointcut="execution(public * com.jd.worldwide.jsf.service.sop..*.*(..))" method="aroundMethod" /> <aop:around pointcut="execution(public * com.jd.worldwide.jsf.service.order..*.*(..))" method="aroundMethod" /> </aop:aspect> </aop:config>
（2）切面类
在切面中进行统一的类型返回，这个统一的类型作为父类被其他类的方法的返回类继承。在这个切面中可以实现简单的统一处理，包括方法监控，方法异常捕获和返回。真正执行目标方法时pjp.proceed()，pjp作为目标类执行的目标类的实例对象，执行目标方法。
@Component("jsfInterceptor") public class JSFInterceptor { private Log log = LogFactory.getLog(this.getClass()); @Autowired private InterfaceAuthDao interfaceAuthDao; private CheckUtil checkUtil; @Autowired private JdRedisUtils jdRedisUtils; // 这个可用来替代以后重复出现的. 直接在后面的Before("myMethod()")就行了. public Object aroundMethod(ProceedingJoinPoint pjp) throws Throwable { // 获取目标对象class类型 String targetClassName = pjp.getTarget().getClass().getName(); // 接口名称 String interfaceName = pjp.getTarget().getClass().getInterfaces()[0].getName(); Signature signature = pjp.getSignature(); // 获取目标方法名称 String methodName = signature.getName(); // 组装目标方法监控key String methodUMPKey = targetClassName + "." + methodName; CallerInfo functionInfo = Profiler.registerInfo((methodUMPKey), UmpProfilerConstant.SYS_NAME, false, true); // 对返回类型的顶层类型做强制控制 Object result = null; MethodSignature methodSignature = (MethodSignature) signature; methodSignature.getMethod(); NoAuthRequired noAuthRequired = methodSignature.getMethod().getAnnotation(NoAuthRequired.class); Class returnType = methodSignature.getReturnType(); // 如果不需要校验权限或者权限校验通过，才能执行业务方法 if (null != noAuthRequired || checkPrivilege(interfaceName)) { result = pjp.proceed(); } else { result = returnType.newInstance(); PropertyUtils.setProperty(result, "success", false); PropertyUtils.setProperty(result, "errorMsg", "权限错误"); } Profiler.registerInfoEnd(functionInfo); return result; } protected boolean checkPrivilege(String targetClass) { if (!checkUtil.isJsfValid()) { return true; } EnumInterfaceKey enums = EnumInterfaceKey.getInterfaceBykey(targetClass); String token = (String) RpcContext.getContext().getAttachment("token"); String appName = (String) RpcContext.getContext().getAttachment("appName"); if (null == enums || null == token || null == appName || enums.getInterfaceType() != EnumInterfaceType.JSF.getInterfaceType()) { log.error("token校验：appName为null或token为null"); return false; } String redisKeyString = RedisKeys.WORLD_WIDE_C2C_PRIVILEGE_VALID + enums.getInterfaceType() + "_" + enums.getInterfaceKey() + "_" + appName + "_" + token; Boolean retValue = (Boolean) jdRedisUtils.getObject(redisKeyString); if (retValue != null) { return retValue; } retValue = false; try { InterfaceAuthQuery query = new InterfaceAuthQuery(); query.setInterfaceType(enums.getInterfaceType()); query.setInterfaceKey(enums.getInterfaceKey()); query.setAppName(appName); List<InterfaceAuth> info = interfaceAuthDao.getInterfaceAuthByquery(query); if (null == info || info.size() <= 0) { log.error("获取权限认证列表为空"); } else if (token.equals(info.get(0).getToken())) { retValue = true; } jdRedisUtils.setObjectByExpire(redisKeyString, retValue, RedisKeys.WORLD_WIDE_C2C_PRIVILEGE_VALID_TIME); } catch (Exception e) { log.error("获取jsf接口权限认证异常e=", e); } return retValue; } public CheckUtil getCheckUtil() { return checkUtil; } public void setCheckUtil(CheckUtil checkUtil) { this.checkUtil = checkUtil; } } 在切面中执行公共的权限校验，异常捕获
