SpringMVC+Spring+Mybatis整合，使用druid连接池，声明式事务，maven配置

一直对springmvc和mybatis挺怀念的，最近想自己再搭建下框架，然后写点什么。
暂时没有整合缓存，druid也没有做ip地址的过滤。Spring的AOP简单配置了下，也还没具体弄，不知道能不能用，log也不知道能不能用，`(*∩_∩*)′哈哈，有点不负责任......
2014-08-12 23:45补：
=================开始=================
1、增加quartz :http://www.cnblogs.com/acehalo/p/3902731.html
2、mybatis添加ehcache缓存：http://www.cnblogs.com/acehalo/p/3902883.html
3、spring的aop: http://www.cnblogs.com/acehalo/p/3905718.html
=================结束================
直接上代码：
使用的eclipse和eclipse自带的maven，参考了网上的资料，有些代码是拷贝的，不过都自己测试过了。嗯，可以跑起来...
先上项目结构：
新建maven项目，选择web，然后配置pom：

======================================================================================
OK，代码贴完了，项目上右键，debug on server应该就能跑起来了。
几个链接可以查看效果：druid的监控信息：http://localhost:8080/Test/druid/sql.html
http://localhost:8080/Test/
http://localhost:8080/Test/text.do
http://localhost:8080/Test/indexList.do
http://localhost:8080/Test/TxTest.do
现在简单讲讲，配置文件里面有注释就不说了：
一：在配置文件添加事务的时候遇到tx标签没用，在xsi:schemaLocation这里添加两行
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
就可以了。
二：还遇到EL表达式不能用，然后
web.xml修改:
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:
<%@ page isELIgnored="false"%>
三：还有c:forEach这种标签不能用
在JSP上增加
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
就可以了
四：spring事务这里
数据库是mysql ，然后表引擎是InnoDB
用navicat在design table---option--engine可以看到
访问http://localhost:8080/Test/TxTest.do之后会出现异常，这个异常是手动抛出的，数据库也没有插入数据。
然后将表的引擎换成MyISAM，保存
之后再访问http://localhost:8080/Test/TxTest.do，发现数据库被插入数据了。
说明：Spring的这个声明事务能使用，MyISAM不支持事务。
五：Controller里的四个方法
第一个方法是一般的测试。
第二个方法是想测试返回json的，主要是@ResponseBody标签。
第三个方法测试LIST。
第四个是测试事务的。
