AspectJ-来自外部JAR的方面

标签： java xml aspectj microprofile

我添加了一个github仓库来准确显示我的问题：

https://github.com/runefist/AspectJ-Stackoverflow-Q

简而言之，我有一个项目，我们将其称为ProjectA。 ProjectA是微型配置文件REST服务器。另一个项目，我们称为ProjectB，是ProjectA（和其他项目）的依赖项。

  • ProjectA（microprofile-REST服务器）
  • ProjectB（ProjectA的依赖项）

ProjectB包含一个方面：

@Aspect
public class ElasticSenderAspect {

    @After("@annotation(elasticsender)") // && execution(* *(..))
    public void after(JoinPoint joinPoint, ElasticSender elasticsender) {
         WebsiteBehaviour websiteBehaviour = new WebsiteBehaviour();  
         websiteBehaviour.setBehaviourFunc(elasticsender.behaviourFunction());
         websiteBehaviour.setBehaviourType(elasticsender.behaviourType());
         ElasticWebsiteBehaviour.sendWebsiteBehaviour(websiteBehaviour);
    }
}

在ProjectA中，我有一个功能：

@GET
@Operation(description = "Authenticate")
@ElasticSender(behaviourFunction = "Authenticate")
public Response authenticate(@HeaderParam("authorization") String authString) {
    if (authString == null) {
        return StandardResponseMessages.GENERAL_NO_AUTHENTICATION.getResponse();
    }
    WebAccount webAccount = webAccountService.find(getUsernameFromAuth(authString));
    boolean correct = false;
    //TODO: CHECK IF ACCOUNT IS VERIFIED
    if (webAccount != null) {
        if (webAccount.getUsername() != null && webAccount.getPassword() != null) {
            if (AuthenticatorUtility.basicAuthenticate(webAccount.getUsername(), webAccount.getPassword(), authString)) {
                correct = true;
            }
        }
    }
    if (correct) {
        return Response.ok(generateTokenString(webAccount)).build();
    } else {
        return StandardResponseMessages.GENERAL_WRONG_AUTHENTICATION.getResponse();
    }
}

我已经测试了Aspect，在我在SAME项目中使用它时，它可以工作，因此不是依赖关系。

问题：

在ProjectB中进行测试时，方面会发生，在ProjectA中进行测试时，方面不会发生。我需要添加什么到ProjectA pom才能使它工作，或者需要更改到ProjectB pom来使其工作？

答案 0 :(得分：1)

在项目A中，除了像已经那样将其作为Maven依赖项添加之外，还需要在AspectJ Maven配置中将B作为aspect library添加：

            <configuration>
                <!-- (...) -->
                <aspectLibraries>
                    <aspectLibrary>
                        <groupId>com.runefist</groupId>
                        <artifactId>ProjectB</artifactId>
                    </aspectLibrary>
                </aspectLibraries>
            </configuration>

我克隆并测试了您的项目，它是通过这种方式工作的。
