转 也显示一下我的Struts2分页struts2分页

转自http://zhangjunji111.iteye.com/blog/582899
  最近看见网上有不少基于Struts2+spring分页的东西，自己感觉都不是很适合，许多都只是对一个列表进行了分页，而没有考虑到查询条件等。个人认为，分页就是从前台把查询条件输入进去然后返回查询结果列表。这个问题的难点就是查询条件的传递，因为第一次查询时候需要输入查询条件，而以后点下一页时候，就不需要再次输入查询条件了。所以，第一次查询时候，需要把查询条件保存到某个地方，再次查询时候，把条件取出来，同时，这些要做的通用，等有许多查询页面时候，能最大限度的重用代码，好了，废话少说，下面展示我的分页代码

首先写一个Pages类，用来保存分页的一些信息，包括当前页码、记录总数、总页数、每页显示的记录数、查询条件等。代码如下：

Java代码
public class Pages {  
    private int pageNo = 1; // 当前页码  
 
    private int totalNum = -1;// 记录总数  
 
    private int totalPage = -1; // 总页数  
 
    int perPageNum = 10; // 每页显示记录数  
 
    private String queryParames;// 查询条件  
 
    public String getQueryParames() {  
        return queryParames;  
    }  
 
    public void setQueryParames(String queryParames) {  
        this.queryParames = queryParames;  
    }  
 
    public Pages() {  
    }  
 
    public Pages(int pageNo, int totalNum, int perPageNum) {  
        this.pageNo = pageNo;  
        this.totalNum = totalNum;  
        this.perPageNum = perPageNum;  
        this.executeCount();  
    }  
 
    public void executeCount() {  
        this.totalPage = (int) Math.ceil((this.totalNum + this.perPageNum - 1)  
                / this.perPageNum);  
        if (this.totalPage <= 0) {  
            this.totalPage = 1;  
        }  
        int intPage = this.pageNo;  
        if (intPage > this.totalPage) {  
            this.pageNo = this.totalPage;  
        } else {  
            this.pageNo = intPage;  
        }  
    }  
 
    public int getPageNo() {  
        return pageNo;  
    }  
 
    public void setPageNo(int pageNo) {  
        this.pageNo = pageNo;  
    }  
 
    public int getPerPageNum() {  
        return perPageNum;  
    }  
 
    public void setPerPageNum(int perPageNum) {  
        this.perPageNum = perPageNum;  
    }  
 
    public int getTotalNum() {  
        return totalNum;  
    }  
 
    public void setTotalNum(int totalNum) {  
        this.totalNum = totalNum;  
    }  
 
    public int getTotalPage() {  
        return totalPage;  
    }  
 
    public void setTotalPage(int totalPage) {  
        this.totalPage = totalPage;  
    }  
 
    public Map transQueryCondition() {  
        Map<String, String> map = new HashMap<String, String>();  
        if (StringUtils.isNull(queryParames)) {  
            return map;  
        }  
        String[] condtions = queryParames.split(";");  
        for (int i = 0; i < condtions.length; i++) {  
            if (StringUtils.isNull(condtions[i])) {  
                continue;  
            }  
            map.put(condtions[i].split(",")[0], condtions[i].split(",")[1]);  
        }  
        return map;  
    } 

public class Pages {
private int pageNo = 1; // 当前页码

private int totalNum = -1;// 记录总数

private int totalPage = -1; // 总页数

int perPageNum = 10; // 每页显示记录数

private String queryParames;// 查询条件

public String getQueryParames() {
return queryParames;
}

public void setQueryParames(String queryParames) {
this.queryParames = queryParames;
}

public Pages() {
}

public Pages(int pageNo, int totalNum, int perPageNum) {
this.pageNo = pageNo;
this.totalNum = totalNum;
this.perPageNum = perPageNum;
this.executeCount();
}

public void executeCount() {
this.totalPage = (int) Math.ceil((this.totalNum + this.perPageNum - 1)
/ this.perPageNum);
if (this.totalPage <= 0) {
this.totalPage = 1;
}
int intPage = this.pageNo;
if (intPage > this.totalPage) {
this.pageNo = this.totalPage;
} else {
this.pageNo = intPage;
}
}

public int getPageNo() {
return pageNo;
}

public void setPageNo(int pageNo) {
this.pageNo = pageNo;
}

public int getPerPageNum() {
return perPageNum;
}

public void setPerPageNum(int perPageNum) {
this.perPageNum = perPageNum;
}

public int getTotalNum() {
return totalNum;
}

public void setTotalNum(int totalNum) {
this.totalNum = totalNum;
}

public int getTotalPage() {
return totalPage;
}

public void setTotalPage(int totalPage) {
this.totalPage = totalPage;
}

public Map transQueryCondition() {
Map<String, String> map = new HashMap<String, String>();
if (StringUtils.isNull(queryParames)) {
return map;
}
String[] condtions = queryParames.split(";");
for (int i = 0; i < condtions.length; i++) {
if (StringUtils.isNull(condtions[i])) {
continue;
}
map.put(condtions[i].split(",")[0], condtions[i].split(",")[1]);
}
return map;
} 下面写一个通用的Action类，用来初始化查询参数：

Java代码
public abstract class ListAction extends ActionSupport {  
    protected static final String LIST = "list";  
 
    Logger logger = Logger.getLogger(ListAction.class);  
 
    /* 
     * 当前页 
     */ 
    private int pageNo = 1;  
 
    /* 
     * 总页数 
     */ 
    private int totalPage = -1;  
 
    /* 
     * 总记录数 
     */ 
    private int totalNum = -1;  
 
    /* 
     * 查询参数 
     */ 
    private String queryParames;  
 
    private PageList pageList;  
 
    public final String execute() {  
        initQuerycondition();  
        Pages pages = new Pages();  
        pages.setPageNo(this.getPageNo());  
        pages.setPerPageNum(10);  
        pages.setTotalNum(totalNum);  
        pages.executeCount();  
        this.setTotalPage(pages.getTotalPage());  
        pages.setQueryParames(queryParames);  
        queryPageList(pages);  
        this.setTotalPage(pages.getTotalPage());  
        this.setTotalNum(pages.getTotalNum());  
        return LIST;  
    }  
 
    /** 
     * 实现每个查询结果列表，依据查询结果的不同而不同 
     * @param pages 
     */ 
    protected abstract void queryPageList(Pages pages);  
 
    /** 
     * 初始化查询参数的配置 
     */ 
    protected void initQuerycondition() {  
        /* 
         *如果不是第一次查询，直接返回，否则设置查询参数，拼装成 queryParames 
         */ 
        if (totalNum >= 0) {  
            return;  
        }  
        Map map = ActionContext.getContext().getParameters();  
        Iterator iter = map.keySet().iterator();  
        StringBuffer query = new StringBuffer();  
        while (iter.hasNext()) {  
            String key = (String) iter.next();  
            Object keyValue = ((Object[]) map.get(key))[0];  
            String value = "";  
            if (!StringUtils.isObjNull(keyValue)) {  
                query.append(";").append(key);  
                if (keyValue instanceof Date) {  
                    value = DateUtils.trunsDateToString((Date) keyValue);  
                } else {  
                    value = String.valueOf(keyValue);  
                }  
                query.append(",").append(value);  
            }  
        }  
        this.setQueryParames(query.toString());  
    }  
 
//get.....set...方法    
} 

public abstract class ListAction extends ActionSupport {
protected static final String LIST = "list";

Logger logger = Logger.getLogger(ListAction.class);

/*
* 当前页
*/
private int pageNo = 1;

/*
* 总页数
*/
private int totalPage = -1;

/*
* 总记录数
*/
private int totalNum = -1;

/*
* 查询参数
*/
private String queryParames;

private PageList pageList;

public final String execute() {
initQuerycondition();
Pages pages = new Pages();
pages.setPageNo(this.getPageNo());
pages.setPerPageNum(10);
pages.setTotalNum(totalNum);
pages.executeCount();
this.setTotalPage(pages.getTotalPage());
pages.setQueryParames(queryParames);
queryPageList(pages);
this.setTotalPage(pages.getTotalPage());
this.setTotalNum(pages.getTotalNum());
return LIST;
}

/**
* 实现每个查询结果列表，依据查询结果的不同而不同
* @param pages
*/
protected abstract void queryPageList(Pages pages);

/**
* 初始化查询参数的配置
*/
protected void initQuerycondition() {
/*
*如果不是第一次查询，直接返回，否则设置查询参数，拼装成 queryParames
*/
if (totalNum >= 0) {
return;
}
Map map = ActionContext.getContext().getParameters();
Iterator iter = map.keySet().iterator();
StringBuffer query = new StringBuffer();
while (iter.hasNext()) {
String key = (String) iter.next();
Object keyValue = ((Object[]) map.get(key))[0];
String value = "";
if (!StringUtils.isObjNull(keyValue)) {
query.append(";").append(key);
if (keyValue instanceof Date) {
value = DateUtils.trunsDateToString((Date) keyValue);
} else {
value = String.valueOf(keyValue);
}
query.append(",").append(value);
}
}
this.setQueryParames(query.toString());
}

//get.....set...方法
}再写一个Page类，继承Component，用来获取ValueStack中的参数值。

Java代码
public class Page extends Component {  
    private static final Log logger = LogFactory.getLog(Page.class);  
    public Page(ValueStack stack) {  
        super(stack);  
    }  
 
    private String pageNo; // 当前页码  
 
    private String totalPage; // 总页数  
 
    private String totalNum; // 总记录数  
 
    private String styleClass; // 分页的样式  
 
    private String theme; // 分页的主题  
 
    private String url; // action的路径  
 
    private String urlType; // 路径的类型，主要用于URL重写的扩展  
 
    private String queryParames;  
 
    public String getQueryParames() {  
        return queryParames;  
    }  
 
    public void setQueryParames(String queryParames) {  
        this.queryParames = queryParames;  
    }  
 
    public boolean start(Writer writer) {  
        boolean result = super.start(writer);  
          
        Object obj = this.getStack().findValue(pageNo);  
 
        pageNo = String.valueOf((Integer) obj);  
 
        obj = this.getStack().findValue(totalPage);  
 
        totalPage = String.valueOf((Integer) obj);  
 
        obj = this.getStack().findValue(totalNum);  
        totalNum = String.valueOf((Integer) obj);  
 
        StringBuilder str = new StringBuilder();  
 
        Map cont = this.getStack().getContext();  
 
        StrutsRequestWrapper req = (StrutsRequestWrapper) cont  
                .get(StrutsStatics.HTTP_REQUEST);  
 
        if (url == null || "".equals(url)) {  
 
            url = (String) req  
                    .getAttribute("javax.servlet.forward.request_uri");  
 
        }  
        String pageStr = "?totalNum=" + totalNum + "&pageNo=";  
 
        if ("dir".equals(urlType)) {  
            pageStr = "";  
 
            if ("1".equals(pageNo)) {// 第一页时  
 
                if (url.lastIndexOf("/") != url.length() - 1) {  
 
                    if (url.lastIndexOf("1") == url.length() - 1) {// 如果有页码1，则去掉1  
 
                        url = url.substring(0, url.length() - 1);  
 
                    } else if (url.lastIndexOf("/") != url.length() - 1) {// 如果没有页码1，并且最后不是'/'时，加上'/'  
 
                        url = url + "/";  
 
                    }  
 
                }  
 
            } else {  
 
                url = url.substring(0, url.lastIndexOf("/") + 1);  
 
            }  
 
        }  
 
          
        // 下面这段处理主要是用来处理动态查询的参数，并拼接成url  
        StringBuffer perUrl = new StringBuffer("");  
        obj = this.getStack().findValue(queryParames);  
        if (!StringUtils.isObjNull(obj)) {  
            perUrl.append("&").append("queryParames").append("=").append(  
                    StringUtils.decode((String) obj));  
        }  
          
        //当前页  
        Integer cpageInt = Integer.valueOf(pageNo);  
        str.append("<span> ");  
        // 文本样式  
        if (theme == null || "text".equals(theme)) {  
            // 当前页与总页数相等  
            if (pageNo.equals(totalPage)) {

                if ("1".equals(totalPage)) {  
                    str.append("[第 " + pageNo + " 页]");  
 
                    str.append(" [共 " + totalPage + " 页]");  
 
                } else {  
 
                    // 到达最后一页,显示“[首页] [上一页] [末页]”  
                    str.append("<a href='" + url + pageStr + "1" + perUrl

  我们在jsp页面直接写

Html代码
<td align="center" nowrap> 
  记录总数  
<s:property value="%{totalNum}" />条  每页显示10条  
第<s:property value="pageNo" />页  <fly:pages pageNo="pageNo" totalPage="totalPage" totalNum="totalNum" styleClass="page" theme="text"  queryParames="queryParames">  </fly:pages> 
</td>
