java.lang.ClassNotFoundException: org.aspectj.lang.JoinPoint

背景：一共三個模塊，還未整合，日誌模塊，登陸模塊以及業務模塊java

登陸模塊應用日誌模塊時啓動正常，可是業務模塊啓動時失敗（分別起的，未整合），報了以下錯誤：web

而後把業務模塊中pom.xml中的build註釋掉，同時增長了網上說的依賴（具體是啥已經亂了，加了好幾個，其中刪除，增長啥的）lua

而後再次運行上面這個錯誤沒有了，可是出現一個Caused by: java.lang.ClassNotFoundException: org.aspectj.lang.ProceedingJoinPoint.net

感受這兩個屬於同一類的，因此就把log模塊有關aop的依賴都放到了業務模塊，就好使了：debug

<dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.8.0</version>
        </dependency>

可是我沒有想明白的是：

一、爲啥登陸模塊沒有引入也能夠？

二、業務模塊是調用，依賴在log模塊存在，爲何要在業務模塊同時存在？
