我正在使用AspectJ监控字段访问和修改。 我有一个Gradle项目,可以编译这两个方面,并将其与aspectjrt和aspectjweaver一起打包到一个阴影jar中,使用Gradle Shadow插件。 代理仍然是org.aspectj.weaver.loadtime.Agent。 一切正常,但当我尝试重新定位AspectJ软件包时,我遇到了错误。
阴影插件的配置如下:
shadowJar {
relocate 'org.aspectj', 'shadow.org.aspectj'
relocate 'aj.org.objectweb.asm', 'shadow.aj.org.objectweb.asm'
}
清单文件:
jar {
manifest {
attributes("Premain-Class": "shadow.org.aspectj.weaver.loadtime.Agent",
"Can-Redefine-Classes": true,
"Can-Retransform-Classes":true)
}
}
这是反编译的方面类,所以它看起来是正确的:
package com.vfunction.singletonanalysis;
import shadow.org.aspectj.lang.JoinPoint;
import shadow.org.aspectj.lang.NoAspectBoundException;
import shadow.org.aspectj.lang.annotation.Aspect;
import shadow.org.aspectj.lang.annotation.Before;
@Aspect
public class StaticFieldBeforeAccessAspect extends AbstractFieldAccessAspect {
public StaticFieldBeforeAccessAspect() {
}
@Before("callAt()")
public void before(JoinPoint joinPoint) throws Throwable {
this.printJoinPoint(joinPoint);
}
public static StaticFieldBeforeAccessAspect aspectOf() {
if (ajc$perSingletonInstance == null) {
throw new NoAspectBoundException("com.vfunction.singletonanalysis.StaticFieldBeforeAccessAspect", ajc$initFailureCause);
} else {
return ajc$perSingletonInstance;
}
}
public static boolean hasAspect() {
return ajc$perSingletonInstance != null;
}
static {
try {
ajc$postClinit();
} catch (Throwable var1) {
ajc$initFailureCause = var1;
}
}
}
但是当我尝试运行测试程序时,仍然会出现错误,提示找到的类型不是一个方面:
