我无法配置Weblogic 12c以使用AspectJ。阅读一些帖子我已经做了一些尝试配置它，但我无法达到结果。我的项目使用maven和aspectj maven插件。我的配置如下：

的pom.xml

我的观点 

package aspectos;

public aspect Logger {
pointcut logger() : call(* co.example..*(..));

before() : logger() {
    System.out.println("#### Signatura: "+thisJoinPointStaticPart.getSignature());
    boolean entro = false;
    for (int i = 0; i < thisJoinPoint.getArgs().length; i++) {
        if(!entro){
            System.out.println("#### Argumentos: ");
            entro=true;
        }
        System.out.println("\t"+thisJoinPoint.getArgs()[i].getClass().toString());
    }
    System.out.println("#### Target: "+thisJoinPoint.getTarget().getClass().toString());
}

after() returning(Object r): logger(){
    if(r!=null){
        System.out.println("#### Objeto retornado: "+r.getClass().getSimpleName());
    }
}

after() throwing(Throwable e): logger(){
    System.out.println("#### Excepcion: "+e.getMessage());
}
}

因此，当我运行 mvn clean install 时，会显示以下错误：

Errors shown by AspectJ

我知道Spring与AspectJ兼容但我无法使用它，我只需要上面显示的配置。如果有人想帮助我，我在github的这个回购中拥有该示例的所有代码：

最后，我正在使用IntelliJ Idea IDE开发我的项目。

全部谢谢

这样的方面看起来有点啰嗦，但没关系（除了你的切入点中的包名称拼写错误co.example而不是com.example）。但是，我建议你做的是使用标准的Maven目录布局，而不是在AspectJ Maven插件中自定义路径，特别是因为IntelliJ IDEA与Maven项目非常相似，能够自动更新IDEA项目设置。改变POM等。

您应该从AspectJ Maven配置中删除这两个参数：

<aspectDirectory>src/java/aspectos</aspectDirectory>
<!-- ... -->
<outputDirectory>${project.reporting.outputDirectory}/aspectj-report</outputDirectory>

我cloned your repo并修复了POM和其他一些东西（包括切入点中的拼写错误，提交的二进制文件等）。我还创建了一个pull request，以便您轻松地将我的更改集成到您的仓库中。最后，但并非最不重要的是，我添加了一个带有main方法的示例独立应用程序，以便能够快速测试整个事物。

现在Maven说：

示例应用程序产生此输出：

#### Argumentos: 
    class java.lang.String
#### Target: class com.example.AccountBean
Executing aspectj
#### Signatura: void com.example.AccountBean.setAmount(float)
#### Argumentos: 
    class java.lang.Float
#### Target: class com.example.AccountBean
Executing aspectj
