Advice AspectJ a method call from different Maven project

由 狂风中的少年 提交于 2020-01-07 00:42:31
问题 I am trying to create an advice of a method of a project (test5) being called from another project (testMaven). I already included the project test5 as dependency in testMaven's pom.xml and set up an advice in testMaven's class but still it doesn't get executed. The calling of the method (dfg) is working just fine. Here are the code for it: MainApp.java (testMaven) package testMaven; import test5.yxc; public class MainApp { public static void main(String[] args) { yxc b = new yxc(); b.dfg(2);

问题 I went through all the possibilities trying to make my project running on Tomcat and point cut the model (getters) and woven them using AspectJ Load Time Weaver. Basically, I followed all the steps in the Spring Documentation http://docs.spring.io/spring/docs/current/spring-framework-reference/html/aop.html#aop-atconfigurable. I also followed the same approach mentioned Lazy/Eager loading/fetching in Neo4j/Spring-Data. My project is divided in two main project: - core: spring-data-neo4j

Spring实现AOP的多种方式

由 本秂侑毒 提交于 2020-01-06 05:54:23
AOP（Aspect Oriented Programming）面向切面编程，通过预编译方式和运行期动态代理实现程序功能的横向多模块统一控制的一种技术。AOP是OOP的补充，是Spring框架中的一个重要内容。利用AOP可以对业务逻辑的各个部分进行隔离，从而使得业务逻辑各部分之间的耦合度降低，提高程序的可重用性，同时提高了开发的效率。AOP可以分为静态织入与动态织入，静态织入即在编译前将需织入内容写入目标模块中，这样成本非常高。动态织入则不需要改变目标模块。Spring框架实现了AOP，使用注解配置完成AOP比使用XML配置要更加方便与直观。 上一篇随笔中已经详细讲了代理模式 。 一、基于XML配置的Spring AOP 在讲注解实现AOP功能前先用前面学习过的使用xml配置Spring AOP功能，这样是为了对比以便更好的理解。 1.1、新建一个Maven项目，添加引用，项目的pom.xml文件如下： <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven

How to make my JLabels red with use of aspectJ?

问题 my Project has a MessageUtil class, which has methods to show messages, I'm trying to make the texts of my Jlabels red using aspectJ, without use of aspectJ it is enough to add 'for loop' to one of the methods wich makes multiLabel text message: public static JLabel[] createMultiLabel(String msg) { JLabel[] messages = null; if (msg.contains("\n")) { messages = createMultiLabelBySlashN(msg); } else { messages = createMultiLabelByPixel(msg); } //this for loop makes the text red for (int i = 0;
