Spring+SpringMVC+Mybatis整合

Spring4.1.6+SpringMVC+Mybatis3.3.0整合 MySQL5.*+文件上传

1.所需jar与解释

Spring+SpringMVC：
        spring-aop-4.1.6.RELEASE.jar
        spring-aspects-4.1.6.RELEASE.jar
        spring-beans-4.1.6.RELEASE.jar
        spring-context-4.1.6.RELEASE.jar
        spring-core-4.1.6.RELEASE.jar
        spring-expression-4.1.6.RELEASE.jar
        spring-jdbc-4.1.6.RELEASE.jar
        spring-orm-4.1.6.RELEASE.jar
        spring-tx-4.1.6.RELEASE.jar
        spring-web-4.1.6.RELEASE.jar
        spring-webmvc-4.1.6.RELEASE.jar
        
        AOP：在Spring2.*中
            aopalliance.jar
            aspectjweaver.jar

        文件上传：在Struts2中
            commons-fileupload-1.2.1.jar
            commons-io-1.3.2.jar

    Mybatis：
        mybatis-3.3.0.jar
        asm-4.2.jar
        cglib-3.1.jar
        commons-logging-1.2.jar
        log4j-1.2.17.jar
        log4j-api-2.2.jar
        log4j-core-2.2.jar
        slf4j-api-1.7.12.jar
        slf4j-log4j12-1.7.12.jar

    Mybatis与Spring整合：
        mybatis-spring-1.2.3.jar

    MySQL驱动包：
        mysql-connector-java-5.1.7-bin.jar
