Question

我有两个项目。我的一个项目（比如project2）依赖于另一个项目（project2）。这两个项目都是maven项目，project1列在project2的依赖项中。当我编译project2时，应将project1中的所有类文件复制到project2（我想象）。但是，我看到project1中某个类文件的文件大小与project2中同一个类的类文件的文件大小不同。如果我反编译文件，我会得到以下结果。

从project1：

中反编译了FacebookUserDetail.class

package com.***.domain.user.external;

import com.***.domain.user.UserDetailType;
import java.util.List;
import javax.persistence.Entity;
import javax.persistence.TypedQuery;
import org.aspectj.lang.JoinPoint;

{

  }

  public static FacebookUserDetail findFacebookUserDetailByFacebookId(String facebookId)
  {
    String str = facebookId; JoinPoint localJoinPoint = Factory.makeJP(ajc$tjp_0, null, null, str); if ((AnnotationDrivenStaticEntityMockingControl.ajc$cflowCounter$1.isValid()) && (AnnotationDrivenStaticEntityMockingControl.hasAspect())) return (FacebookUserDetail)findFacebookUserDetailByFacebookId_aroundBody1$advice(str, localJoinPoint, AnnotationDrivenStaticEntityMockingControl.aspectOf(), null, ajc$tjp_0, localJoinPoint); return findFacebookUserDetailByFacebookId_aroundBody0(str, localJoinPoint);
  }

  public UserDetailType getExternalUserDetailType()
  {
    return UserDetailType.FACEBOOK;
  }

  static
  {
    ajc$preClinit(); } 
  public static long countFacebookUserDetails() { return FacebookUserDetail_Roo_Entity.ajc$interMethod$com_nim_domain_user_external_FacebookUserDetail_Roo_Entity$com_nim_domain_user_external_FacebookUserDetail$countFacebookUserDetails(); } 
  public static List<FacebookUserDetail> findAllFacebookUserDetails() { return FacebookUserDetail_Roo_Entity.ajc$interMethod$com_nim_domain_user_external_FacebookUserDetail_Roo_Entity$com_nim_domain_user_external_FacebookUserDetail$findAllFacebookUserDetails(); } 
  public static FacebookUserDetail findFacebookUserDetail(Long paramLong) { return FacebookUserDetail_Roo_Entity.ajc$interMethod$com_nim_domain_user_external_FacebookUserDetail_Roo_Entity$com_nim_domain_user_external_FacebookUserDetail$findFacebookUserDetail(paramLong); }

  public static TypedQuery<FacebookUserDetail> findFacebookUserDetailsByUserIdEquals(String paramString) { return FacebookUserDetail_Roo_Finder.ajc$interMethod$com_nim_domain_user_external_FacebookUserDetail_Roo_Finder$com_nim_domain_user_external_FacebookUserDetail$findFacebookUserDetailsByUserIdEquals(paramString); } 
  public String toString() { return FacebookUserDetail_Roo_ToString.ajc$interMethod$com_nim_domain_user_external_FacebookUserDetail_Roo_ToString$com_nim_domain_user_external_FacebookUserDetail$toString(this); }

}

从project2

中反编译了FacebookUserDetail.class

package com.***.domain.user.external;

{

  {
    JoinPoint localJoinPoint = Factory.makeJP(ajc$tjp_1, this, this); if ((!AnnotationBeanConfigurerAspect.ajc$if$bb0((Configurable)getClass().getAnnotation(Configurable.class))) && (AbstractDependencyInjectionAspect.ajc$if$6f1(localJoinPoint))) AnnotationBeanConfigurerAspect.aspectOf().ajc$afterReturning$org_springframework_beans_factory_aspectj_AbstractDependencyInjectionAspect$2$1ea6722c(this);
  }

  public static FacebookUserDetail findFacebookUserDetailByFacebookId(String facebookId)
  {
    String str = facebookId; JoinPoint localJoinPoint = Factory.makeJP(ajc$tjp_0, null, null, str); if ((AnnotationDrivenStaticEntityMockingControl.ajc$cflowCounter$1.isValid()) && (AnnotationDrivenStaticEntityMockingControl.hasAspect())) return (FacebookUserDetail)findFacebookUserDetailByFacebookId_aroundBody1$advice(str, localJoinPoint, AnnotationDrivenStaticEntityMockingControl.aspectOf(), null, ajc$tjp_0, localJoinPoint); return findFacebookUserDetailByFacebookId_aroundBody0(str, localJoinPoint);
  }

  public UserDetailType getExternalUserDetailType()
  {
    return UserDetailType.FACEBOOK;
  }

  static
  {
    ajc$preClinit();
  }
}

我的问题是：在project2中截断类文件的可能原因是什么？

Answer 1

关于这一部分：当我编译project2时，应将project1中的所有类文件复制到project2

事实并非如此，如果项目是jar类型，maven会将两个项目编译成两个独立的jar，如果项目2的类型为WAR，则将project1.jar复制到project2的WEB-INF / lib中。

两个类文件之间的区别表明project2的版本没有应用Roo方面，尽管它也是用AspectJ编译的。

尝试仅通过关闭所有IDE从命令行构建项目，并比较两个版本以查看是否仍存在相同的问题。可能是您的IDE正在使用aspectJ编译类，但没有正确的Roo方面。

还要看看这个report必须在依赖和依赖项目上添加aspectj插件，以及关于Roo多模块maven支持的3.7.2.2. Limitations上的本文档。
