java – 使用Spring AOP \u0026\u0026 MVC进行排序
我正在尝试使用
Spring AOP与
Spring MVC Controller.
我有3个方面,希望按照具体的顺序.为了做到这一点,我使用Ordered接口并实现getOrder方法: @Aspect @Component public class LoggingAspect implements Ordered{ public int getOrder() { System.out.println("Abra"); return 1; } 推荐课程: @Component @Controller public class HomeController { 切入点: @Aspect public class SystemArchitecture { @Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))") public void inHomeController(){} @Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))") public void loggable(){} @Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))") public void authenticated(){} } 组态: <?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> <annotation-driven /> <context:annotation-config /> <aop:aspectj-autoproxy proxy-target-class="false"/> <beans:bean id="AuthenticationAspect" class="com.jajah.CommonAspects.SecurityAspects.OAuthAspect"/> <beans:bean id="ErrorHandlingAspect" class="com.jajah.StorageManager.Aspects.ErrorHandlingAspect"/> <!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory --> <resources mapping="/resources/**" location="/resources/" /> <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory --> <!-- <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <beans:property name="prefix" value="/WEB-INF/views/" /> <beans:property name="suffix" value=".jsp" /> </beans:bean> --> <beans:bean name="homeController" class="com.jajah.StorageManager.HomeController"> <beans:constructor-arg> <beans:ref bean="CloudStorage"/> </beans:constructor-arg> <beans:constructor-arg> <beans:ref bean="ConfigurationContainer"/> </beans:constructor-arg> </beans:bean> <beans:bean id="CloudStorage" name="CloudStorage" class="com.jajah.StorageManager.CloudStorageProxy" scope="singleton"> <beans:constructor-arg> <beans:ref bean="ConfigurationContainer"/> </beans:constructor-arg> </beans:bean> <beans:bean id ="ConfigurationContainer" class="com.jajah.StorageManager.ConfigurationContainer" scope="singleton"/> </beans:beans> getOrder没有办法. 我会根据需求发布任何代码/配置. 更新: 解决方法
您不需要实现有序接口.
在Spring AOP中,您可以轻松地做些事情. @Aspect @Order(1) public class AspectA { @Before("............") public void doit() {} } @Aspect @Order(2) public class AspectB { @Before(".............") public void doit() {} } 更新: @Aspect @Order(1) public class SpringAspect { @Pointcut("within(com.vanilla.service.MyService+)") public void businessLogicMethods(){} @Around("businessLogicMethods()") public Object profile(ProceedingJoinPoint pjp) throws Throwable { System.out.println("running Advice #1"); Object output = pjp.proceed(); return output; } } @Aspect @Order(2) public class SpringAspect2 { @Pointcut("within(com.vanilla.service.MyService+)") public void businessLogicMethods(){} @Around("businessLogicMethods()") public Object profile(ProceedingJoinPoint pjp) throws Throwable { System.out.println("running Advice #2"); Object output = pjp.proceed(); return output; } } 现在应用程序上下文配置XML: <context:annotation-config /> <aop:aspectj-autoproxy /> <bean id="springAspect" class="com.vanilla.aspect.SpringAspect" /> <bean id="springAspect2" class="com.vanilla.aspect.SpringAspect2" /> 您需要通过以下方式启用AOP代理: <aop:aspectj-autoproxy /> 否则不会激活任何建议. 更新2: 我只是在研究这个问题. @order注解只适用于基于Spring的代理AOP(我在我的例子中使用).如果您正在使用编织,请使用declare precedence选项. 更新3 >我的代码中没有任何建议,只是方面和切入点. 那么您需要将其配置为 <bean id="systemArchitecture" class="x.y.z.SystemArchitecture" /> 我的代码中没有看到它. >“执行(* com.jajah.StorageManager.HomeController.*(..))”你的目标是什么?你能用字写吗? 无论如何.请在Facebook上给我留言,我会发送你正在做什么的工作示例.
