• 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================
    复制代码

    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。
