无法将AspectJ与Maven集成 [英] Not able to integrate AspectJ with Maven

问题描述

我敲了两天的脑袋，将Aspectj与Maven集成在一起，但是没有用. 我正在编写一个带有两个建议的简单程序(在Eclipse中可以正常工作，因此我确定这不是代码方面的错误).

I banged my head for two days to integrate aspectj with maven, But did not work. I am writing a simple program with two advices (which works fine in eclipse, so I am sure it's not a code side error).

我最近开始使用maven进行项目构建.想不到为什么我无法启动Aspectj编译器.

I have recently started using maven for project building. Can't think of why I am not able to kick off aspectj compiler.

在通过Maven进行编译期间-我只得到Java的类文件，而没有进行编织. .aj文件未编译.

During compilation through maven - I get only class file for java without weaving. .aj file is not compiled.

请帮助！！！

第一个方面文件-ExceptionAspects.aj

the first aspect file - ExceptionAspects.aj

package com.aspectSample;

public aspect ExceptionAspects {

pointcut ExceptionHandler(Exception e) : handler(Exception+) && args(e) && within(com.clickable.*);
pointcut callbeforeMethod():execution( public void HelloWorldExclude.*(..)) ;

before(Exception ex) : ExceptionHandler(ex)
{       
    System.out.println("Added Aspects before Exception :"+ex.toString());
}

before(): callbeforeMethod()
{
    System.out.println("Aspect Before Method Call");
}


pointcut sysOutOrErrAccess() : get(* System.out) || get(* System.err);

declare error
  : sysOutOrErrAccess()
  : "Don't write to the console";

}

源Java文件HelloWorldExclude.java 包com.aspectSample;

The source java file HelloWorldExclude.java package com.aspectSample;

    import java.sql.SQLException;

    public class HelloWorldExclude {

 private void FoulIntro(String message, String name) throws SQLException
    {
        throw new SQLException("WriteSomething");
    }

 public void GiveMeFoulIntro(String message, String name)
    {
        try
        {
            this.FoulIntro(message, name);

        }catch(SQLException exp)
        {
            System.out.println("catching exception");
        }
    }
}

并且pom.xml文件是

and the pom.xml file is

推荐答案

pom文件中存在一个愚蠢的错误. Aspectj插件已添加到element下，这只是所有插件的配置.它没有告诉编译器使用什么.

There was a stupid mistake in pom file. aspectj plugin was added under element, which is just a configuration of all plugins. It doesn't tell compiler what to use.

只要我从该元素中删除了插件，它就会起作用.

It worked as soon as I removed plugin out of this element.
