1.SSM基础框架
1. 创建user数据表 create table t_user( id int(11) NOT NULL AUTO_INCREMENT, userName varchar(20) DEFAULT NULL, password varchar(20) DEFAULT NULL, PRIMARY KEY(id) )ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8; insert into t_user values(1, 'andrew', '123456'); 2. 新建MyBatisPro05项目
3. 导入jar包 asm-3.3.jar asm-commons-3.3.jar asm-tree-3.3.jar c3p0-0.9.1.jar com.springsource.net.sf.cglib-2.2.0.jar com.springsource.org.aopalliance-1.0.0.jar com.springsource.org.aspectj.weaver-1.6.8.RELEASE.jar commons-logging-1.1.3.jar javassist-3.11.0.GA.jar log4j-1.2.16.jar mybatis-3.2.5.jar mybatis-spring-1.2.0.jar mysql.jar ognl-3.0.6.jar spring-aop-4.0.6.RELEASE.jar spring-aspects-4.0.6.RELEASE.jar spring-beans-4.0.6.RELEASE.jar spring-context-4.0.6.RELEASE.jar spring-core-4.0.6.RELEASE.jar spring-expression-4.0.6.RELEASE.jar spring-jdbc-4.0.6.RELEASE.jar spring-orm-4.0.6.RELEASE.jar spring-tx-4.0.6.RELEASE.jar spring-web-4.0.6.RELEASE.jar spring-webmvc-4.0.6.RELEASE.jar
