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......

=================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:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
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:
<%@ 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。
