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。
