不能讓我的方面運行

Question

基本上我有一個普通的Java應用程序，與主。我使用Intelij Ultimate。我有以下朋友

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

     </dependency> 

     <!-- https://mvnrepository.com/artifact/log4j/log4j -->

     </dependency> 

     <!-- https://mvnrepository.com/artifact/aspectj/aspectjrt --> 
     <dependency> 
      <groupId>aspectj</groupId> 
      <artifactId>aspectjrt</artifactId> 
      <version>1.5.4</version> 
     </dependency> 



    </dependencies> 

    <build> 
     <plugins> 
      <plugin> 
       <groupId>org.apache.maven.plugins</groupId> 
       <artifactId>maven-compiler-plugin</artifactId> 
       <version>3.5.1</version> 
       <configuration> 
        <source>1.8</source> 
        <target>1.8</target> 
       </configuration> 
      </plugin> 
     </plugins> 
    </build> 
</project> 

所以我也有一個LoggingAspect，我只是不知道如何運行。我也試過這個http://confluence.jetbrains.com/display/~roman.shevchenko/AspectJ+Support+Plugin

手動下載了jar，但我也下載了方面的Intelij插件。像AspectJ支持和Spring方面一樣。

我的切面類看起來是這樣的：

public aspect LoggingAspect { 
    pointcut tracing():call(public * com.company..*.*(..)) && !within(LoggingAspect); 

    private Logger logger= Logger.getLogger("com.company"); 

    public LoggingAspect() { 
     PropertyConfigurator.configure("logging.properties"); 
    } 

    before(): tracing(){ 
     logger.info("Entering: "+ thisJoinPointStaticPart.getSignature()); 
    } 

    after():tracing(){ 
     logger.info("Exiting: "+ thisJoinPointStaticPart.getSignature()); 
    } 
} 

正如你所看到的。我想使用java.util.logging.Logger，我有一個logging.properties文件，我在其中設置輸出文件。我嘗試編譯應用程序，就像上面粘貼的鏈接，正常運行應用程序，似乎沒有任何工作。我的方面根本沒有工作/沒有被使用。有什麼建議？我錯過了什麼嗎？

我不想用註釋尚未使用Spring Aspect。我不知道如何使這一個第一個工作

我改變了我的編譯器爲ajc和測試連接，一切都很好。我已經將Aspectjrt添加到依賴關係中......當我嘗試運行該程序時，它仍然不會執行任何操作。它只是正常運行而不應用這些方面。 任何想法？

這是編譯時編織的解決方案。因爲所有主要的IDE都可以從Maven導入和更新項目，所以它可以在Eclipse，IntelliJ IDEA以及NetBeans（從未嘗試過）中工作。

Maven的POM：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Log4J的配置文件：

# Root logger option 
log4j.rootLogger=INFO, stdout 

# Direct log messages to stdout 
log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
log4j.appender.stdout.Target=System.out 
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n 

驅動程序：

package com.company.app; 

public class Application { 
    public static void main(String[] args) { 
    new Application().doSomething("foo", 11); 
    } 

    public String doSomething(String string, int i) { 
    return "blah"; 
    } 
} 

改進方面：

加載logging.properties的方式只能在JAR中使用，但不能在IDE中運行代碼時使用。我建議你依賴從Maven項目正確導入的類路徑，將配置文件放在src/main/resources之下，然後通過ClassLoader.getResourceAsStream(..)打開它。

package com.company.aspect; 

import org.apache.log4j.Logger; 
import org.apache.log4j.PropertyConfigurator; 

public aspect LoggingAspect { 
    private static final Logger logger = Logger.getLogger("com.company"); 

    public LoggingAspect() { 
    PropertyConfigurator.configure(
     Thread 
     .currentThread() 
     .getContextClassLoader() 
     .getResourceAsStream("logging.properties") 
    ); 
    } 

    pointcut tracing() : 
    call(public * com.company..*.*(..)) && 
    !within(LoggingAspect); 

    before() : tracing() { 
    logger.info("Entering: " + thisJoinPointStaticPart.getSignature()); 
    } 

    after() : tracing() { 
    logger.info("Exiting: " + thisJoinPointStaticPart.getSignature()); 
    } 
}

2017-04-02 17:58:06 INFO company:27 - Exiting: String com.company.app.Application.doSomething(String, int)
