首先配置問題,在配置檔案裡 新增包的掃描

把對應的註解了的類,解析為相應元件:

 配置檔案 命名規則為 xxxResource.xml ,我這裡叫 scanResource.xml.

包掃描,是掃描你的 controller 等類所在包位置

scanResource.xml 裡的 程式碼

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:module="http://www.sgcc.com.cn/schema/platform/module"

	<context:component-scan base-package="top.jacktu.controller" />
	<context:component-scan base-package="top.jacktu.bizc" />
</beans>
 

然後是程式碼結構,檢視.  我這裡沒怎麼用到 Emp 所以 有 Emp 字樣的 java類 你可以忽略它

bizc 是 業務邏輯層,controller 是對請求的處理方法. po 是放 javaBean 的.

基本就這些,程式碼粘過去哪裡不能實現.自行解決吧,應該也不會有什麼大問題.
