我试图让AspectJ在一个现有项目中工作(实际上,我对该项目知之甚少,因为它似乎并不重要).

我们决定使用加载时间编织以避免使用ajc

因为我是AspectJ的新手,所以我首先创建了一个示例项目,其中包含一些类和日志记录方面：

@Aspect
public class LoggingAspect {

    @Pointcut("call(public de.test.beans.IPerson+.*(..))")
    public void logExecutions(JoinPoint jp) {}

    @Before("logExecutions(jp)")
    public void beforeExecutions(JoinPoint jp) {
        BeforeExecutionLog log = new BeforeExecutionLog(jp);
        System.out.println(log);                
    }

    @AfterReturning(pointcut = "logExecutions(jp)", returning = "ret")
    public void afterExecutions(JoinPoint jp, Object ret) {
        AfterExecutionLog log = new AfterExecutionLog(jp, ret);        
        System.out.println(log);        
    }    

}

一切正常,一切都很好.

下一步,我尝试同时使用AspectJ和Maven.我只是稍微更改了日志记录方面(只是软件包).

根据《 AspectJ in Action》一书中的代码,我修改了我们的maven pom.xml.

       <dependencies>
            ...
        <dependency>
           <groupId>org.aspectj</groupId>
           <artifactId>aspectjrt</artifactId>

        </dependency>

        <dependency>

            <artifactId>aspectjweaver</artifactId>

        </dependency>       
       </dependencies>
        <plugin>                                                 
            <groupId>org.codehaus.mojo</groupId>            
            <artifactId>aspectj-maven-plugin</artifactId>
            <version>1.4</version>
            <executions>                                         
                <execution>                                      
                    <goals>                                      
                        <goal>compile</goal>                     
                    </goals>                                     
                    <configuration>                              
                        <source>1.5</source>                     
                        <target>1.5</target>                     
                    </configuration>                             
                </execution>                                     
            </executions>                                        
        </plugin>   

但是如果尝试调用mvn clean install我会遇到成千上万个错误,第一个错误是：

[ERROR] Syntax error on token "call(public xxx.yyy.zzz.api.Service+.*(..))", "name pattern" expected
[ERROR] Method annotated with @Pointcut() for abstract pointcut must be abstract

还有以下错误：

[ERROR] The method xyz() of type zyx must override a superclass method

我想这些都是受我方面影响的方法.

谁能解释我,怎么了？

先感谢您

UPD：

我更新了我的问题.

解决方法:

您的示例似乎不完整,显示的错误与代码不匹配,但是使用以下pom.xml编译方面类时,我看不到任何问题：
