Struts2+Spring+Hibernate+Jbpm技术实现Oa(Office Automation)办公系统第一天框架搭建
=============编码规范,所有文健,所有页面,所有数据库的数据表都采用UTF-8编码格式,避免乱码;===========开发环境:jdk1.7+tomcat8.0+mysql5.7+eclipse Mars.2 Release (4.5.2)
1:创建一个动态web项目,名称如Oa;
2:创建一个Oa的数据库,并且创建一个新用户只可以操作Oa这个数据库;
1 ----创建数据库2 create database Oa default character set utf8;3 4 -----创建用户5 create user biexiansheng identified by ‘123456‘;6 7 -----为用户授权8 grant all on Oa.* to biexiansheng;
温馨提示:创建好之后使用的是Navicat连接的数据库,注意连接名和用户名是自己起的比如我的别先生,密码也是自己的比如我的123456。
3:导入各个框架的jar包:
3.1:第一步,先导入struts2的jar包,如下所示:
asm-3.3.jar
asm-commons-3.3.jar
asm-tree-3.3.jar
commons-fileupload-1.3.1.jar
commons-io-2.2.jar
commons-lang-2.4.jar
freemarker-2.3.19.jar
javassist-3.11.0.GA.jar
ognl-3.0.6.jar
struts2-core-2.3.16.3.jar
struts2-spring-plugin-2.3.16.3.jar
xwork-core-2.3.16.3.jar
然后配置一下web.xml的前端控制器:
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> 3 <display-name>Oa</display-name> 4 <welcome-file-list> 5 <welcome-file>index.html</welcome-file> 6 <welcome-file>index.htm</welcome-file> 7 <welcome-file>index.jsp</welcome-file> 8 <welcome-file>default.html</welcome-file> 9 <welcome-file>default.htm</welcome-file>10 <welcome-file>default.jsp</welcome-file>11 </welcome-file-list>12 13 14 <!-- 配置struts2的前端控制器 -->15 <filter>16 <filter-name>struts2</filter-name>17 <!-- struts2-core-2.3.16.3.jar这个jar包里面查找 -->18 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>19 </filter>20 <filter-mapping>21 <filter-name>struts2</filter-name>22 <url-pattern>/*</url-pattern>23 </filter-mapping>24 25 26 27 28 </web-app>
然后再复制一下struts.xml的配置文件放到src/config下面,模板如下所示:
<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"><!-- struts2的配置信息 --><struts> <!-- 将对象工厂指定为spring --> <constant name="struts.objectFactory" value="spring"></constant> <!-- struts的Action的访问后缀,必须以.do结尾 --> <constant name="struts.action.extension" value="do"></constant> <package name="default" namespace="/" extends="struts-default"> <action name=""> <result></result> </action> </package></struts>
3.2:导入spring的jar包:如下所示:
com.springsource.com.mchange.v2.c3p0-0.9.1.2.jar
com.springsource.org.aopalliance-1.0.0.jar
com.springsource.org.apache.commons.logging-1.1.1.jar
com.springsource.org.apache.log4j-1.2.15.jar
com.springsource.org.aspectj.weaver-1.6.8.RELEASE.jar
spring-aop-3.2.5.RELEASE.jar
spring-aspects-3.2.5.RELEASE.jar
spring-beans-3.2.5.RELEASE.jar
spring-context-3.2.5.RELEASE.jar
spring-core-3.2.5.RELEASE.jar
spring-expression-3.2.5.RELEASE.jar
spring-jdbc-3.2.5.RELEASE.jar
spring-orm-3.2.5.RELEASE.jar
spring-tx-3.2.5.RELEASE.jar
spring-web-3.2.5.RELEASE.jar
然后在web.xml里面配置一下spring的上下文载入器和监听器,配置如下所示:
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> 3 <display-name>Oa</display-name> 4 <welcome-file-list> 5 <welcome-file>index.html</welcome-file> 6 <welcome-file>index.htm</welcome-file> 7 <welcome-file>index.jsp</welcome-file> 8 <welcome-file>default.html</welcome-file> 9 <welcome-file>default.htm</welcome-file>10 <welcome-file>default.jsp</welcome-file>11 </welcome-file-list>12 13 <!-- 通过上下文参数指定spring配置文件的位置 -->14 <context-param>15 <param-name>contextConfigLocation</param-name>16 <param-value>classpath:beans.xml</param-value>17 </context-param>18 19 <!-- 配置spring的上下文载入器监听器,项目启动时加载spring -->20 <listener>21 <!-- 22 方法:ctrl+shift+t 搜索ContextLoaderListener 23 spring-web-3.2.5.RELEASE.jar24 -->25 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>26 </listener> 27 28 29 <!-- 配置struts2的前端控制器 -->30 <filter>31 <filter-name>struts2</filter-name>32 <!-- struts2-core-2.3.16.3.jar这个jar包里面查找 -->33 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>34 </filter>35 <filter-mapping>36 <filter-name>struts2</filter-name>37 <url-pattern>/*</url-pattern>38 </filter-mapping>39 40 41 42 43 </web-app>
然后在src/config下面配置一下spring的配置文件:(由于使用的是注解扫描的,所以会使用开启注解和组件扫描)
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xmlns:aop="http://www.springframework.org/schema/aop" 7 xmlns:tx="http://www.springframework.org/schema/tx" 8 xsi:schemaLocation="http://www.springframework.org/schema/beans 9 http://www.springframework.org/schema/beans/spring-beans.xsd10 http://www.springframework.org/schema/context11 http://www.springframework.org/schema/context/spring-context.xsd12 http://www.springframework.org/schema/aop13 http://www.springframework.org/schema/aop/spring-aop.xsd14 http://www.springframework.org/schema/tx15 http://www.springframework.org/schema/tx/spring-tx.xsd">16 17 18 <!-- IoC容器的配置,也叫控制反转,要创建的所有的对象都配置在这里 -->19 20 <!-- 读取属性文件 -->21 <context:property-placeholder location="classpath:jdbc.properties"/>22 23 <!-- 数据源 -->24 <!-- 25 ctrl+shift+t搜索ComboPooledDataSource26 -->27 <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">28 <property name="driverClass" value="${driverClass}"></property>29 <property name="jdbcUrl" value="${jdbcUrl}"></property>30 <property name="user" value="${user}"></property>31 <property name="password" value="${password}"></property>32 <property name="initialPoolSize" value="${initialPoolSize}"></property>33 <property name="minPoolSize" value="${minPoolSize}"></property>34 <property name="maxPoolSize" value="${maxPoolSize}"></property>35 </bean>36 37 <!-- 本地回话工厂bean -->38 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">39 <!-- 注入数据源 -->40 <property name="dataSource" ref="dataSource"></property>41 42 <!-- 注入hibernate属性 -->43 <property name="hibernateProperties">44 <props>45 <!-- mysql的方言,由于使用工作流框架所以使用这个方言 -->46 <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>47 48 <prop key="hibernate.hbm2ddl.auto">true</prop>49 50 <prop key="hibernate.show_sql">true</prop>51 52 <prop key="hibernate.format_sql">true</prop>53 </props>54 55 </property>56 57 58 <!-- hibernate的映射文件 -->59 <property name="mappingDirectoryLocations">60 <list>61 <value>classpath:com/oa/po</value>62 </list>63 </property>64 65 </bean>66 67 <!-- hibernate的事务管理器 -->68 <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">69 <property name="sessionFactory" ref="sessionFactory"></property>70 </bean>71 72 <!-- 对注解的支持 -->73 <context:annotation-config></context:annotation-config>74 <!-- 组件扫描 -->75 <context:component-scan base-package="com.oa"></context:component-scan>76 77 <!-- 注解驱动 -->78 <tx:annotation-driven transaction-manager="txManager"/>79 80 81 </beans>
创建一个jdbc.properties配置文件,配置如下所示:
1 driverClass=com.mysql.jdbc.Driver2 jdbcUrl=jdbc:mysql://localhost:3306/oa3 user=biexiansheng4 password=1234565 initialPoolSize=206 minPoolSize=207 maxPoolSize=40
创建一个log4j.properties配置文件,用于记录日志的相关信息:(记得修改自己的日志保存的文件路径,在第9行)
1 ### direct log messages to stdout ### 2 log4j.appender.stdout=org.apache.log4j.ConsoleAppender 3 log4j.appender.stdout.Target=System.err 4 log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 5 log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n 6 7 ### direct messages to file mylog.log ### 8 log4j.appender.file=org.apache.log4j.FileAppender 9 log4j.appender.file.File=E:\Android_java_resouce\JAVA_EE\eclipse\workspace\mylog.log10 log4j.appender.file.layout=org.apache.log4j.PatternLayout11 log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n12 13 ### set log levels - for more verbose logging change ‘info‘ to ‘debug‘ ###14 15 log4j.rootLogger=info, stdout
3.3:导入hibernate的相关jar包,如下所示:
1 antlr-2.7.6.jar 2 commons-collections-3.1.jar 3 dom4j-1.6.1.jar 4 hibernate-jpa-2.0-api-1.0.0.Final.jar 5 hibernate3.jar 6 javassist-3.12.0.GA.jar 7 jta-1.1.jar 8 mysql-connector-java-5.1.40-bin.jar 9 slf4j-api-1.6.1.jar10 slf4j-log4j12-1.7.2.jar
4:创建项目包结构,搭建的项目结构如下所示:
5:项目搭建好之后将项目放到本地tomat下面跑一下,看看搭建的项目是否出现错误:
温馨提示:假如最后跑项目出现错误,请不要着急,仔细分析,应该可以很快解决问题;
所谓万事开头难,开好头,加油!生命不息,运动不止;
