ide: idea
lib包的导入：http://webcache.googleusercontent.com/search?q=cache:http://zyjustin9.iteye.com/blog/2172445
applicationContext.xml 文件：
如果是java project项目，那么要放在src目录下，同时，需要用 <aop: 来导入p
idea会自动检测此文件，根据上方提示加入spring配置即可
xml 方式 配置 bean：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- Product 注入 Category对象 -->
<bean id="product" class="com.how2java.pojo.Product" aop:name="kinome_product" aop:category-ref="category"></bean> </beans>

// Category category = ctx.getBean(Category.class);

package com.how2java.pojo;
public class Product {
private int id;

public void setId(int id) {
