Spring AOP：AopConfigException：无法生成类

Question

以下是我的LoggingAspect.java

import java.util.logging.Level;
import java.util.logging.Logger;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;


@Aspect
@Component
public class LoggingAspect {

    private static Logger logger = Logger.getLogger(LoggingAspect.class.getName());
    private static final String ENTERING = "(AOP) Entering ";
    private static final String EXITING = "(AOP) Exiting ";
    private static final String RETURNING = "(AOP) Returning for class ";
    private static final String EXCEPTION = "(AOP): Exception ";

    @Pointcut("execution(* com.adminserver..*(..)) && " + "!within(is(EnumType)) && " + "!within(is(FinalType))")
    protected void loggingOperation() {
        // intentionally left blank
    }

    private String getArguments(Object[] obj) {
        String str = "{";
        for (int i = 0; i < obj.length && obj[i] != null; i++)
            str += obj[i].toString() + ",";
        str += "}";
        return str;
    }

    @Before("loggingOperation()")
    public void logEntry(final JoinPoint joinPoint) {
        String msg = ENTERING + joinPoint.getTarget().getClass().getName() + " " + joinPoint.getSignature().getName()
                + " Arguments: " + getArguments(joinPoint.getArgs());

        logger.log(Level.INFO, msg);

    }

    @After("loggingOperation()")
    public void logExit(final JoinPoint joinPoint) {
        logger.log(Level.INFO, EXITING + joinPoint.getTarget().getClass().getName() + " "
                + joinPoint.getSignature().getName() + " Arguments:" + getArguments(joinPoint.getArgs()));
    }

    @AfterReturning(pointcut = "loggingOperation()", returning = "result")
    public void logReturn(final JoinPoint joinPoint, Object result) {
        String msg = RETURNING + joinPoint.getTarget().getClass().getName() + ", Method: "
                + joinPoint.getSignature().getName() + " Return Value: ";
        if (result != null)
            logger.log(Level.INFO, msg + result.toString());
        else
            logger.log(Level.INFO, msg + "NULL");

    }

    @AfterThrowing(pointcut = "loggingOperation()", throwing = "ex")
    public void logException(JoinPoint joinPoint, Throwable ex) throws Throwable {
        String msg = EXCEPTION + joinPoint.getTarget().getClass().getName() + " " + joinPoint.getSignature().getName();
        logger.log(Level.SEVERE, msg, ex);
    }

}

尝试使用以下两个配置（在SO上搜索答案后）：

<aop:aspectj-autoproxy proxy-target-class="true"/>和 <aop:aspectj-autoproxy proxy-target-class="false"/>

应用程序正在运行，它正在按预期运行代码的某些部分。但是对于其他一些部分，它会抛出这样的东西：

使用了lib：

<dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.8.10</version>
</dependency>

正如您所看到的，我使用

排除了所有枚举类型和最终类

@Pointcut("execution(* com.adminserver..*(..)) && " + "!within(is(EnumType)) && " + "!within(is(FinalType))")

但是在日志中它仍然会抱怨Common causes of this problem include using a final class or a non-visible class;

Answer 1

在切入点表达式中添加!within(com.adminserver..*.generatedClasses..*)并且它有效。

以下是完整的表达。

@Pointcut("execution(public * com.adminserver..*(..)) && " + "!within(is(EnumType)) && " + "!within(is(FinalType)) && "+"!within(com.adminserver..*.generatedClasses..*)")
    protected void loggingOperation() {
        // intentionally left blank
    }
