java使用druid maven_SpringMVC+Spring+Mybatis整合，使用druid连接池，声明式事务，maven配置...
一直對springmvc和mybatis挺懷念的，最近想自己再搭建下框架，然后寫點什么。
暫時沒有整合緩存，druid也沒有做ip地址的過濾。Spring的AOP簡單配置了下，也還沒具體弄，不知道能不能用，log也不知道能不能用，`(*∩_∩*)′哈哈，有點不負責任......
2014-08-12 23:45補：
=================開始=================1、增加quartz :http://www.cnblogs.com/acehalo/p/3902731.html
2、mybatis添加ehcache緩存：http://www.cnblogs.com/acehalo/p/3902883.html
3、spring的aop: http://www.cnblogs.com/acehalo/p/3905718.html
=================結束================
直接上代碼：
使用的eclipse和eclipse自帶的maven，參考了網上的資料，有些代碼是拷貝的，不過都自己測試過了。嗯，可以跑起來...
先上項目結構：
新建maven項目，選擇web，然后配置pom：

OK，代碼貼完了，項目上右鍵，debug on server應該就能跑起來了。
現在簡單講講，配置文件里面有注釋就不說了：
一：在配置文件添加事務的時候遇到tx標簽沒用，在xsi:schemaLocation這里添加兩行
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
就可以了。
二：還遇到EL表達式不能用，然后
web.xml修改:
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
jsp增加:
三：還有c:forEach這種標簽不能用
在JSP上增加
就可以了
四：spring事務這里
數據庫是mysql ，然后表引擎是InnoDB
用navicat在design table---option--engine可以看到
然后將表的引擎換成MyISAM，保存
說明：Spring的這個聲明事務能使用，MyISAM不支持事務。
五：Controller里的四個方法
第一個方法是一般的測試。
第二個方法是想測試返回json的，主要是@ResponseBody標簽。
第三個方法測試LIST。
第四個是測試事務的。
總結
以上是生活随笔為你收集整理的java使用druid maven_SpringMVC+Spring+Mybatis整合，使用druid连接池，声明式事务，maven配置...的全部內容，希望文章能夠幫你解決所遇到的問題。
