    SSH项目整合基本步骤

    一、项目简介

    　　该项目是由Spring4、Struts2 以及 Hibernate4 整合搭建的 web 项目，把Action分开编写，便于查看，使用JSTL、EL标签。

    二、项目目录

    三、项目所需Jar包

    　　①Spring：

    　　aopalliance-1.0.jar
    　　aspectjweaver.jar
    　　spring-aop-4.3.0.RELEASE.jar
    　　spring-aspects-4.3.0.RELEASE.jar
    　　spring-beans-4.3.0.RELEASE.jar
    　　spring-context-4.3.0.RELEASE.jar
    　　spring-core-4.3.0.RELEASE.jar
    　　spring-expression-4.3.0.RELEASE.jar
    　　spring-jdbc-4.3.0.RELEASE.jar
    　　spring-orm-4.3.0.RELEASE.jar
    　　spring-tx-4.3.0.RELEASE.jar
    　　spring-web-4.3.0.RELEASE.jar

    　　②Struts2：

    　　asm-5.0.2.jar
    　　asm-commons-5.0.2.jar
    　　asm-tree-5.0.2.jar

    　　freemarker-2.3.19.jar
    　　ognl-3.0.6.jar
    　　struts2-core-2.3.20.jar
    　　struts2-spring-plugin-2.3.20.jar
    　　xwork-core-2.3.20.jar

    　　③Hibernate：

    　　antlr-2.7.7.jar
    　　dom4j-1.6.1.jar
    　　hibernate-commons-annotations-4.0.5.Final.jar
    　　hibernate-core-4.3.11.Final.jar
    　　hibernate-jpa-2.1-api-1.0.0.Final.jar
    　　jandex-1.1.0.Final.jar
    　　jboss-logging-3.1.3.GA.jar
    　　jboss-logging-annotations-1.2.0.Beta1.jar
    　　jboss-transaction-api_1.2_spec-1.0.0.Final.jar

    　　④C3P0：

    　　c3p0-0.9.5.1.jar
    　　mchange-commons-java-0.2.10.jar
    　　mysql-connector-java-5.1.8-bin.jar

    　　⑤JSTL：

    　　taglibs-standard-impl-1.2.5.jar
    　　taglibs-standard-jstlel-1.2.5.jar
    　　taglibs-standard-spec-1.2.5.jar

    　　⑥log4j：

    　　log4j-1.2.17.jar

    四、项目源码

    1、db.properties

    1 db.username=root
2 db.password=root
3 db.driverClass=com.mysql.jdbc.Driver
4 db.jdbcUrl=jdbc:mysql://localhost:3306/ssh_01
5 db.initialPoolSize=2
6 db.maxPoolSize=20

    2、log4j.properties

     1 # Global logging configuration
 2 log4j.rootLogger=ERROR, stdout
 3 # MyBatis logging configuration...
 4 log4j.logger.org.mybatis.example.BlogMapper=TRACE
 5 # Console output...
 6 log4j.appender.stdout=org.apache.log4j.ConsoleAppender
 7 log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
 8 log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
 9 # Start logging
10 log4j.logger.cn.com.zfc.model.UserMapper=TRACE

    3、applicationContext.xml（可以把通用的配置抽取出来，便于管理）
