SSH 基本配置--OA系统的经典配置

说明：
此SSH架构时OA系统的经典配置
绝对是最经典的配置，您值得拥有

一、structs配置文件

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"    "http://struts.apache.org/dtds/struts-2.3.dtd"><struts>    <constant name="struts.devMode" value="true" />    <!-- 全局国际化配置 -->    <constant name="struts.custom.i18n.resources" value="messages"></constant>    <constant name="struts.action.extension" value="action,do"/>    <constant name="struts.configuration.xml.reload" value="true"></constant>    <constant name="struts.multipart.maxSize" value="10240000"></constant>    <!-- 表示Action由Spring来进行创建，可以直接使用Spring依赖注入来注入 -->    <constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />    <constant name="struts.ui.theme" value="simple"></constant>      <!-- 允许使用静态方法 -->    <constant name="struts.ognl.allowStaticMethodAccess" value="true"></constant>      <package name="default" namespace="/" extends="json-default">        <interceptors>            <interceptor name="privilegeInterceptor" class="com.ssh.oa.filter.PrivilegeInteceptor"></interceptor>            <interceptor-stack name="defaultStack">                <interceptor-ref name="privilegeInterceptor"></interceptor-ref>                <interceptor-ref name="defaultStack"></interceptor-ref>            </interceptor-stack>        </interceptors>        <global-results>            <result name="error">/WEB-INF/jsp/inc/error.jsp</result>            <result name="exception">/WEB-INF/jsp/inc/exception.jsp</result>            <result name="noPrivilege">/WEB-INF/jsp/inc/noPrivilege.jsp</result>            <result name="loginUI">/WEB-INF/jsp/user/loginUI.jsp</result>        </global-results>        <global-exception-mappings>            <exception-mapping result="exception" exception="com.ssh.document.exeception.MyExeception"></exception-mapping>        </global-exception-mappings>        <!-- 跟方法名不相同的都必须写 -->        <action name="*_*" class="{1}Action" method="{2}">            <result name="{2}">/WEB-INF/jsp/{1}/{2}.jsp</result>            <result name="saveUI">/WEB-INF/jsp/{1}/saveUI.jsp</result>            <result name="toList" type="redirectAction">{1}_list?parentId=${parentId}</result>            <result name="loginUI">/WEB-INF/jsp/{1}/loginUI.jsp</result>            <result name="logout">/WEB-INF/jsp/{1}/logout.jsp</result>            <result name="toIndex" type="redirect">/index.jsp</result>            <result name="toTopicShow" type="redirectAction">topic_show?id=${topicId}</result>            <result name="toShow" type="redirectAction">{1}_show?id=${id}</result>            <result name="downloadProcessImage" type="stream">                <param name="contentType">image/png</param>                <param name="inputName">inputStream</param>            </result>            <result name="download" type="stream">                <param name="contentType">application/octet-stream</param>                <param name="inputName">inputStream</param>                <param name="contentDisposition">attachment;fileName="${#fileName}</param>            </result>                       <result name="toMyApplicationList" type="redirectAction">{1}_myApplicationList</result>            <result name="toMyTaskList" type="redirectAction">{1}_myTaskList</result>        </action>    </package></struts>

二、applicationContext.xml配置文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

三、数据库配置文件jdbc.properties

jdbc.driver = com.mysql.jdbc.Driverjdbc.url = jdbc:mysql:///ssh_oa?characterEncoding=UTF-8jdbc.user = rootjdbc.password=root

四、Web.xml配置文件

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">    <!-- 配置Spring的用于初始化容器对象的监听器 -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:applicationContext*.xml</param-value>    </context-param>    <listener>        <listener-class>com.ssh.oa.filter.InitPrivilegeListener</listener-class>    </listener>    <filter>        <filter-name>CharacterEncodingFilter</filter-name>        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>        <init-param>            <param-name>encoding</param-name>            <param-value>UTF-8</param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>CharacterEncodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!-- 配置Spring的用于解决懒加载问题的过滤器 -->    <filter>        <filter-name>OpenSessionInViewFilter</filter-name>        <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>OpenSessionInViewFilter</filter-name>        <url-pattern>*.action</url-pattern>    </filter-mapping>    <!-- 配置Struts2的核心的过滤器 -->    <filter>        <filter-name>struts2</filter-name>        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>struts2</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <listener>        <listener-class>org.apache.struts2.dispatcher.ng.listener.StrutsListener</listener-class>    </listener>    <welcome-file-list>        <welcome-file>login.jsp</welcome-file>    </welcome-file-list></web-app>

五、相关jar包

六、Dao层的基本方法
1)DaoSupport.java

public interface DaoSupport<T> {    public void save(T t);    public void update(T t);    public void delete(Serializable...ids);    public T loadById(Serializable id);    public void delete(Long id);    public T getById(Long id);    public T findByObj(String hql, Object...objs);    public List<T> listByIds(Serializable...ids);    public List<T> findByIds(Long...ids);    public List<T> listAll();    public PageBean getPageBean(int pageNum, int pageSize, QueryHelper queryHelper);}

2)DaoSupportImpl.java
