如何在Gradle项目中使用带有Profiled注释的Perf4J?

我有一个Java Gradle项目,我正在尝试使用Perf4J。我发现了一些只有Maven的Perf4J的例子。所以,我修改了一个并运行它。这是可用的Java类和Maven构建文件。

package com.mycompany.testapplication;

import org.apache.log4j.Appender;
import org.apache.log4j.ConsoleAppender;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.apache.log4j.SimpleLayout;
import org.perf4j.aop.Profiled;

/**
 *
 * @author Ankit Gupta
 */
public class TestClass {

    final static Logger myLogger = Logger.getLogger("org.perf4j.TimingLogger");
    final static Appender myAppender;

    static {
        myLogger.setLevel(Level.ALL);
        // Define Appender     
        myAppender = new ConsoleAppender(new SimpleLayout());

        //myAppender.setLayout(new SimpleLayout());  
        myLogger.addAppender(myAppender);
    }

    public static void main(String[] args) {
        TestClass test = new TestClass();
        test.run();
    }

    @Profiled(
            tag = "sampleTag"
    )
    private void run() {
        try {
            Thread.sleep(5000);
        } catch (InterruptedException ex) {
            java.util.logging.Logger.getLogger(TestClass.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        }
    }

}

和pom.xml

上面的代码工作正常,并给我预期的输出。现在,我想对我的gradle项目做同样的事情,但我不知道如何做。因为,我正在使用@Profiled注释,我意识到我想要AspectJ。我找到了这个plugin并为同一个Java类编写了一个build.gradle文件,如下所示:

apply plugin: 'java'

sourceCompatibility = '1.6'

if (!hasProperty('mainClass')) {
    ext.mainClass = 'com.mycompany.testapplication.TestClass'
}

buildscript {
    repositories {
        maven {
            url "https://maven.eveoh.nl/content/repositories/releases"
        }
    }

    dependencies {
        classpath "nl.eveoh:gradle-aspectj:1.4"
    }
}

repositories {
    mavenCentral()
}

dependencies{
    compile 'org.perf4j:perf4j:0.9.16'
    compile 'org.aspectj:aspectjrt:1.6.7'
    compile 'org.perf4j:perf4j:0.9.13:log4jonly'
    compile 'commons-jexl:commons-jexl:1.1'
    compile 'log4j:log4j:1.2.17'
}

project.ext {
    aspectjVersion = '1.6.7'
}

apply plugin: 'aspectj'

gradle build cleangradle run命令不会出现任何错误或警告。但是,我没有在控制台上看到perf4j日志。我该如何解决这个问题,以便我可以将perf4j与Gradle一起使用?

您忘记指定编织的外部代码(ajInpath行)。我采用了你的脚本(包含的应用程序插件,用gradle run执行,更新版本号并更改为Java 8:

buildscript {
    repositories {
        maven { url "https://maven.eveoh.nl/content/repositories/releases" }
    }

    dependencies {
        classpath "nl.eveoh:gradle-aspectj:1.4"
    }
}

project.ext {
    aspectjVersion = '1.8.1'
}

apply plugin: 'java'
apply plugin: 'aspectj'
apply plugin: 'application'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.perf4j:perf4j:0.9.16:log4jonly'
    compile 'org.aspectj:aspectjrt:1.8.1'
    compile 'commons-jexl:commons-jexl:1.1'
    compile 'log4j:log4j:1.2.17'

    ajInpath 'org.perf4j:perf4j:0.9.16:log4jonly'
}

sourceCompatibility = '1.8'
mainClassName = 'com.mycompany.testapplication.TestClass'

使用Gradle 2.0测试。将版本号放入变量并使用gradle包装器是个好主意。
