Spring AOP_学习记录_01

版权声明： https://blog.csdn.net/qq_38386316/article/details/88790660

1. 在eclipse中加入spring aop 的依赖包

1.1 所需依赖如下所示:

• aopalliance-1.0.jar
• asm-3.3.1.jar
• aspectj-1.7.1.jar
• aspectjrt-1.7.0.jar(在aspectj-1.7.1.jar里面)
• aspectjweaver-1.7.0.jar(在aspectj-1.7.1.jar里面)
• cglib-2.2.2.jar
  我找这几个依赖时，除了aspectj-1.7.1.jar,其余都是在这个Meven下载Search 一下你所要找的jar包就可以了 的。

1.2 在eclipse中配置aspectj的库文件就可以了:
配置方法可以参考spring_fragment_学习记录 01.

1.2 First Aspect

• org.zcs.springAop - AopMain.java

package org.zcs.springAop;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.zcs.springAop.service.ShapeService;

public class AopMain {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		ApplicationContext ctx = new ClassPathXmlApplicationContext("spring.xml");
		ShapeService shapeservice = ctx.getBean("shapeService", ShapeService.class);
		System.out.println(shapeservice.getCircle().getName());
	}

}

• org.zcs.springAop.asepect-LoggingAspect.java

package org.zcs.springAop.aspect;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;

@Aspect
public class LoggingAspect {
	@Before("execution(	public String getName())")
	public void LoggingAdvice() {
		System.out.println("Advice running.... Get Method called.");
	}
}

• org.zcs.springAop.model-Circle

package org.zcs.springAop.model;

public class Circle {
	private String name;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
}

• org.zcs.springAop.model-Triangle.java

package org.zcs.springAop.model;

public class Triangle {
	private String name;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	
}

• org.zcs.springAop.service-ShapeService.java

package org.zcs.springAop.service;

import org.zcs.springAop.model.Circle;
import org.zcs.springAop.model.Triangle;

public class ShapeService {
	private Circle circle;
	private Triangle triangle;
	public Circle getCircle() {
		return circle;
	}
	public void setCircle(Circle circle) {
		this.circle = circle;
	}
	public Triangle getTriangle() {
		return triangle;
	}
	public void setTriangle(Triangle triangle) {
		this.triangle = triangle;
	}
	
}

• spring.xml

       <bean name = "circle" class = "org.zcs.springAop.model.Circle">

 		<bean name= "loggingAspect" class = "org.zcs.springAop.aspect.LoggingAspect"></bean>
 </beans>

3.学习记录。

• 其中bean文件中的头文件来自官网的参考文件中可以找到。
• 学习了aspect的应用，和在bean中的配置。
• 复习了bean中的自动装载的知识。
