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

        </action>

    </package>

</struts>

二、applicationContext.xml配置文件

    <!-- 配置AOP，Spring是通过AOP来进行事务管理的 -->
    <aop:config>
        <!-- 设置pointCut表示哪些方法要加入事务处理 -->
        <!-- 以下的事务是声明在DAO中，但是通常都会在Service来处理多个业务对象逻辑的关系，注入删除，更新等，此时如果在执行了一个步骤之后抛出异常 
            就会导致数据不完整，所以事务不应该在DAO层处理，而应该在service，这也就是Spring所提供的一个非常方便的工具，声明式事务 -->

    </bean>
    <bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine" />

</beans>

三、数据库配置文件jdbc.properties

jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql:///ssh_oa?characterEncoding=UTF-8
jdbc.user = root
jdbc.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"

    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext*.xml</param-value>

    <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>

    </listener>

    <welcome-file-list>
        <welcome-file>login.jsp</welcome-file>
    </welcome-file-list>
</web-app>

七、分页类

@SuppressWarnings("all")
public class PageBean {

    private List dataList = new ArrayList();// 本页的数据列表
    private int pageNum;// 当前页
    private int pageSize;// 每页显示多少条
    private int recordCount;// 总记录数
    private int pageCount;// 总页数    
    private int beginIndex;// 页码列表的开始索引（包含）
    private int endIndex;// 页码列表的结束索引（包含）


    public PageBean(int pageNum, int pageSize, int recordCount, List dataList){
        this.pageNum = pageNum;
        this.pageSize = pageSize;
        this.dataList = dataList;
        this.recordCount = recordCount;
        // 计算总页码
        pageCount = (recordCount + pageSize - 1)/pageSize;

        //如果pageCount<10就全部显示
        if (pageCount <= 10) {
            beginIndex = 1;
            endIndex = pageCount;
        }else {
            //如果pageCount>10显示pageNum前4后5
            beginIndex = pageNum - 4;
            endIndex = pageNum + 5;
            if (pageNum<1) {
                beginIndex = 1;
                endIndex = 10;
            }else if (pageNum > pageCount) {
                beginIndex = pageNum - 9;
                endIndex = pageCount;
            }
        }
    }



    public List getDataList() {
        return dataList;
    }
    public void setDataList(List dataList) {
        this.dataList = dataList;
    }
    public int getPageSize() {
        return pageSize;
    }
    public void setPageSize(int pageSize) {
        this.pageSize = pageSize;
    }

    public int getPageNum() {
        return pageNum;
    }

    public void setPageNum(int pageNum) {
        this.pageNum = pageNum;
    }



    public int getRecordCount() {
        return recordCount;
    }



    public void setRecordCount(int recordCount) {
        this.recordCount = recordCount;
    }



    public int getPageCount() {
        return pageCount;
    }



    public void setPageCount(int pageCount) {
        this.pageCount = pageCount;
    }



    public int getBeginIndex() {
        return beginIndex;
    }



    public void setBeginIndex(int beginIndex) {
        this.beginIndex = beginIndex;
    }



    public int getEndIndex() {
        return endIndex;
    }



    public void setEndIndex(int endIndex) {
        this.endIndex = endIndex;
    }
