annotations 相关问题

我正在使用 Spring AOP 登录我的应用程序。这是 applicationContext.xml 文件我正在使用 Spring AOP 登录我的应用程序。这是 applicationContext.xml 文件 <mvc:annotation-driven /> <context:component-scan base-package="com.template" /> <context:annotation-config /> <jpa:repositories base-package="com.template.repository"/> <tx:annotation-driven /> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/template?autoReconnect=true"/> <property name="username" value="root"/> <property name="password" value=""/> </bean> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml"/> <property name="persistenceUnitName" value="template"/> </bean> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory"/> </bean> 我的 aopLogging.xml 是 <bean id="aopLogging" class="com.template.log.AopLoggingAspect" /> <aop:aspectj-autoproxy proxy-target-class="false"/> 我的 Aspect 类是 import org.apache.log4j.Logger; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.springframework.stereotype.Component; import org.springframework.util.StopWatch; @Aspect @Component public class AopLoggingAspect { private static final Logger logger = Logger.getLogger(AopLoggingAspect.class); @Around(value="@annotation(com.template.log.Loggable)") public Object logAround(final ProceedingJoinPoint joinPoint) throws Throwable{ Object retVal = null; try { StringBuffer startMessageStringBuffer = new StringBuffer(); startMessageStringBuffer.append("Start method execution :: "); startMessageStringBuffer.append(joinPoint.getSignature().getName()); startMessageStringBuffer.append("("); Object[] args = joinPoint.getArgs(); for (int i = 0; i < args.length; i++) { startMessageStringBuffer.append(args[i]).append(","); } if (args.length > 0) { startMessageStringBuffer.deleteCharAt(startMessageStringBuffer.length() - 1); } startMessageStringBuffer.append(")"); logger.info(startMessageStringBuffer.toString()); StopWatch stopWatch = new StopWatch(); stopWatch.start(); retVal = joinPoint.proceed(); stopWatch.stop(); StringBuffer endMessageStringBuffer = new StringBuffer(); endMessageStringBuffer.append("Finish method "); endMessageStringBuffer.append(joinPoint.getSignature().getName()); endMessageStringBuffer.append("(..); execution time: "); endMessageStringBuffer.append(stopWatch.getTotalTimeMillis()); endMessageStringBuffer.append(" ms;"); logger.info(endMessageStringBuffer.toString()); } catch(Exception ex) { StringBuffer errorMessageStringBuffer = new StringBuffer(); logger.error(errorMessageStringBuffer.toString(), ex); throw ex; } return retVal; } } 我的自定义注释是 import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; @Retention(RetentionPolicy.RUNTIME) @Target({ElementType.METHOD, ElementType.TYPE}) public @interface Loggable { } 我的服务等级是 public class UserService { @Transactional(readOnly=true) @Loggable public User getUserByUserId(Long userId){ return userRepository.findOne(userId); } } 问题是没有打印日志。请帮我。提前致谢。如果需要任何其他信息，请告诉我。在我看来你忘了在你的applicationContext.xml文件中导入aopLogging.xml文件。尝试将此添加到您的applicationContext.xml文件中：  <import resource="classpath:aopLogging.xml" /> 创建注释 @Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) public @interface LogExecutionTime { } 然后一个看点 @看点 @组件公共类 LoggingAspect { 然后Aspect中的一个方法 @Around("@annotation(LogExecutionTime)") 公共对象 logExecutionTime(ProceedingJoinPoint joinPoint) 抛出 Throwable { long start = System.currentTimeMillis(); Object proceed = joinPoint.proceed(); long executionTime = System.currentTimeMillis() - start; LOGGER.info(joinPoint.getSignature() + " executed in " + executionTime + "ms"); return proceed; } 然后使用Annotation Anywhere @PostMapping（价值=“/注册”） @LogExecutionTime 公共@ResponseBody ResponseObject 注册（用户用户）{ } 试试这个.. @Around(value="@annotation(Loggable)") public Object logAround(final ProceedingJoinPoint joinPoint) throws Throwable{
