篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了快速搭建一个SSM框架demo相关的知识,希望对你有一定的参考价值。

我之所以写一个快速搭建的demo,主要想做一些容器的demo,所以为了方便大家,所以一切从简,简单的3层架构

先用mysql的ddl,后期不上oracle的ddl

预先准备:用插件自动生成自动生成DAO层,链接在(后期补上)

第一步:创建maven工程,导入依赖包,目前我的工程暂时叫MyArtifact

第二步:

创建3个资源文件(最简化的)

mybatis-config.xml          (一些mybatis 的设置,和插件,例:pagehelper)

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC  
    "-//mybatis.org//DTD Config 3.0//EN"

    <!-- 分页插件 -->

        </plugin>
    </plugins>
</configuration> 
mybatis-config.xml

第二个配置文件 applicationContext-*.xml(或者取其他名字)

作用:1>.数据源(两个例子)

上升超过maxIdle,而造成频繁的连接销毁和创建,类似于jvm参数中的Xmx设置) -->
<property name="maxIdle" value="${jdbc.maxIdle}" />

<!-- 连接池中最小的空闲的连接数,低于这个数量会被创建新的连接(默认为0,调整为5,该参数越接近maxIdle,性能越好, 因为连接的创建和销毁,都是需要消耗资源的; 
但是不能太大,因为在机器很空闲的时候,也会创建低于minidle个数的连接,类似于jvm参数中的Xmn设置) -->
<property name="minIdle" value="${jdbc.minIdle}" />

<!-- 并发连接的最大数。设置为0则无限制 -->
<property name="maxTotal" value="${jdbc.maxTotal}" />

<!-- 等待连接的最大连接的时间,以毫秒计 -->
<property name="maxWaitMillis" value="${jdbc.maxWaitMillis}" />

<!--SQL查询,用来验证从连接池取出的连接,在将连接返回给调用者之前. -->
<property name="validationQuery" value="select sysdate from dual" />

<!--指明是否在从池中取出连接前进行检验,如果检验失败,则从池中去除连接并尝试取出另一个 -->
<property name="testOnBorrow" value="true" />

   2>. 数据库配置SqlSessionFactoryBean(主要是:扫描mapper,定义事物管理)

        <property name="configLocation" value="classpath:mybatis-config.xml" />
