AspectJ

Question

我添加了一个 github 回购协议，它准确地显示了我的问题：

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

简而言之，我有一个项目，我们称之为 ProjectA。 ProjectA 是一个 microprofile-REST-server。另一个项目，我们称之为 ProjectB，是 ProjectA（和其他项目）的依赖项。

ProjectA（microprofile-REST-server）
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 中我有一个函数：

@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，当我在 SAME 项目中使用它时它可以工作，所以不是依赖项。

问题：

在 ProjectB 中测试时出现方面，在 ProjectA 中测试时不会出现方面。我需要向 ProjectA pom 添加什么才能使其正常工作，或者我需要将什么更改为 ProjectB pom 才能使其正常工作？

Answer 1

在项目 A 中，您需要将 B 作为 aspect library 添加到 AspectJ Maven 配置中，此外还要像您已经做的那样将其添加为 Maven 依赖项：

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

我克隆并测试了你的项目，它是这样工作的。

Answer 2

我遇到了同样的问题，将 spring-aop 依赖项添加到 projectB 帮助了我。

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-aop</artifactId>
  <version>5.3.18</version>
</dependency>

并且projectA中不需要添加aspectj插件，

    <dependency>
        <groupId>com.runefist</groupId>
        <artifactId>ProjectB</artifactId>
        <version>1.0.0</version>
    </dependency>
