Spring+SpringMVC+Mybatis框架搭建

SSM在企业开发中也是一个常用的框架，后台使用SSM框架搭建 
下面完成框架搭建 写一个junit测试方法完成简单数据插入来验证框架集成是否成功
1.第一步 准备SSM框架所需的jar包 
为了方便jar包的管理 使用maven引入工程所需的jar包 如果不知道如何在web工程中支持maven的话 请移步看这篇文档
http://blog.csdn.net/dtlscsl/article/details/50235759
按照链接文档中的步骤完成工程搭建之后 通过maven的配置引入下面三个框架依赖的jar包 

Spring 4.0.2 RELEASE

Spring MVC 4.0.2 RELEASE

MyBatis 3.2.6

pom.xml配置文件如下：

<properties><!-- spring版本号 --><spring.version>4.0.2.RELEASE</spring.version><!-- mybatis版本号 --><mybatis.version>3.2.6</mybatis.version><!-- log4j日志文件管理包版本 --><

;slf4j.version>1.7.7</slf4j.version><log4j.version>1.2.17</log4j.version></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><!-- 表示开发的时候引入，发布的时候不会加载此包 --><scope>test</scope></dependency><!-- spring核心包 --><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-oxm</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${spring.version}</version></dependency><!-- mybatis核心包 --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatis.version}</version></dependency><!-- mybatis/spring包 --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.2.2</version></dependency><!-- 导入java ee jar 包 --><dependency><groupId>javax</groupId><artifactId>javaee-api</artifactId><version>7.0</version></dependency><!-- 导入Mysql数据库链接jar包 --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.30</version></dependency><!-- 导入dbcp的jar包，用来在applicationContext.xml中配置数据库 --><dependency><groupId>commons-dbcp</groupId><artifactId>commons-dbcp</artifactId><version>1.2.2</version></dependency><!-- JSTL标签类 --><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><!-- 日志文件管理包 --><!-- log start --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>${log4j.version}</version></dependency><!-- 格式化对象，方便输出日志 --><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.1.41</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>${slf4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${slf4j.version}</version></dependency><!-- log end --><!-- 映入JSON --><dependency><groupId>org.codehaus.jackson</groupId><artifactId>jackson-mapper-asl</artifactId><version>1.9.13</version></dependency><!-- 上传组件包 --><dependency><groupId>commons-fileupload</groupId><artifactId>commons-fileupload</artifactId><version>1.3.1</version></dependency><dependency><groupId>commons-io</groupId><artifactId>commons-io</artifactId><version>2.4</version></dependency><dependency><groupId>commons-codec</groupId><artifactId>commons-codec</artifactId><version>1.9</version></dependency></dependencies>

2.第二步 添加工程配置文件
~日志配置文件 log4j.properties
http://www.cnblogs.com/suman/archive/2010/10/23/1858864.html
# 定义日志输出级别为debug级别 R为输出目的地 后面用逗号分隔 可以指定多个日志输出地方

#定义LOG输出级别

log4j.rootLogger=INFO,Console

#定义日志输出目的地为控制台

log4j.appender.Console=org.apache.log4j.ConsoleAppender

log4j.appender.Console.Target=System.out

#可以灵活地指定日志输出格式，下面一行是指定具体的格式

log4j.appender.Console.layout = org.apache.log4j.PatternLayout

log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

~数据库配置文件 jdbc.properties

driver=com.mysql.jdbc.Driver

url=jdbc:mysql://127.0.0.1:3306/test

username=root

password=12345

initialSize=0

maxActive=20

maxIdle=20

minIdle=1

maxWait=60000

框架的配置文件我分成了4个文件
~applicationContext.xml: 配置文件总入口 引入多个xml配置

3.第三步 整合框架 完成一个简单查询功能测试，测试mybatis与数据库的连接
创建一张测试表：
CREATE TABLE user(name varchar(255),password varchar(255));
编写测试代码
