我在向 Maven 项目添加方面时遇到问题。我准备了小演示:
Project1
仅包含一个基本类
public class Sender {
public static void main(String[] args) {
System.out.println("here main");
}
}
它的pom.xml
:
<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">
<modelVersion>4.0.0</modelVersion>
<groupId>Project1</groupId>
<artifactId>Project1</artifactId>
<version>0.0.1-SNAPSHOT</version>
<properties>
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>

</execution>
</executions>
<configuration>
<source>${maven.compiler.source}</source>
<target>${maven.compiler.target}</target>
<aspectLibraries>
<aspectLibrary>
<groupId>Project2</groupId>
<artifactId>Project2</artifactId>
</aspectLibrary>
</aspectLibraries>
</configuration>
</plugin>
</plugins>
</build>
<dependencies>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>

</dependency>
<dependency>
<groupId>Project2</groupId>
<artifactId>Project2</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
</project>
并Project2
包含一个方面:
@Aspect
public class AspectL {
@Pointcut("execution(* main(..))")
public void defineEntryPoint() {
}
@Before("defineEntryPoint()")
public void aaa(JoinPoint joinPoint) {
System.out.println("aspect before");
}
@After("defineEntryPoint()")
public void bbb(JoinPoint joinPoint) {
System.out.println("aspect after");
}
}
及其pom
<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>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.6.11</version>
<scope>compile</scope>
</dependency>
</dependencies>
</project>
但结果,当我尝试运行Sender
时
Exception in thread "main" java.lang.NoSuchMethodError: AspectL.aspectOf()LAspectL;
at Sender.main(Sender.java:6)
你有什么建议吗?我是否以正确的方式配置这些项目?还好吗pom
?任何帮助将不胜感激。
