如何在 war 包中配置与 Weblogic 12c 一起使用的 AspectJ

Question

我无法配置 Weblogic 12c 以使用 AspectJ。阅读一些帖子我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：

我的看点

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 时显示此错误：

Errors shown by AspectJ

我知道 Spring 与 AspectJ 兼容，但我不能使用它，我只需要上面显示的配置。如果有人想帮助我，我在 github:

中有这个 repo 中示例的所有代码

最后，我正在使用 IntelliJ Idea 开发我的项目 IDE。

感谢大家

这样的方面看起来有点冗长，但还可以（除了包名拼写错误 co.example 而不是切入点中的 com.example ）。不过，我建议您做的是使用标准的 Maven 目录布局，而不是在 AspectJ Maven 插件中自定义路径，尤其是因为 IntelliJ IDEA 与 Maven 项目配合得非常好，无论何时您都能够自动更新 IDEA 项目设置更改 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 and fixed the POM and a few other things (typos in package names in pointcuts, committed binaries etc.) for you. I also created a pull request是为了让您能够轻松地将我的更改集成到您的存储库中。最后但同样重要的是，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过程。

现在 Maven 说：

示例应用程序产生以下输出：

#### Argumentos:

#### Target: class com.example.AccountBean
Executing aspectj
#### Signatura: void com.example.AccountBean.setAmount(float)
