Pager-taglib在项目中的使用

1建立LocalThread类,对分页的常数进行封装

代码如下

[java]
<SPAN style="FONT-SIZE: 18px"> package com.tgb.oa;
    /**
     *
     *    采用ThreadLocal来存储分页变量.
     * @author   jnqqls
     * @group    TGB
     * @version 1.0
     * @comments
     */
    public class SystemContext {
        private static ThreadLocal offset = new ThreadLocal();
        private static ThreadLocal pagesize = new ThreadLocal();

        /**
         * 从线程中获取offset字段
         * @return
         */
        public static int getOffset(){
            Integer os = (Integer)offset.get();
            if(os == null){
                return 0;
            }
            return os;
        }

        public static void setOffset(int offsetvalue){
            offset.set(offsetvalue);
        }

        public static void removeOffset(){
            offset.remove();
        }

        public static int getPagesize(){
            Integer ps = (Integer)pagesize.get();
            if(ps == null){
                return Integer.MAX_VALUE;
            }
            return ps;
        }

        public static void setPagesize(int pagesizevalue){
            pagesize.set(pagesizevalue);
        }

        public static void removePagesize(){
            pagesize.remove();
        }

    }
</SPAN>

package com.tgb.oa;
/**
*
*    采用ThreadLocal来存储分页变量.
* @author   jnqqls
* @group    TGB
* @version 1.0
* @comments
*/
public class SystemContext {
  private static ThreadLocal offset = new ThreadLocal();
  private static ThreadLocal pagesize = new ThreadLocal();

  /**
   * 从线程中获取offset字段
   * @return
   */
  public static int getOffset(){
   Integer os = (Integer)offset.get();
   if(os == null){
    return 0;
   }
   return os;
  }

  public static void setOffset(int offsetvalue){
   offset.set(offsetvalue);
  }

  public static void removeOffset(){
   offset.remove();
  }

  public static int getPagesize(){
   Integer ps = (Integer)pagesize.get();
   if(ps == null){
    return Integer.MAX_VALUE;
   }
   return ps;
  }

  public static void setPagesize(int pagesizevalue){
   pagesize.set(pagesizevalue);
  }

  public static void removePagesize(){
   pagesize.remove();
  }

}

2建立PagerFilter过滤器,将参数读取到ThreadLocal中.

代码如下:

[java]
<SPAN style="FONT-SIZE: 18px"> package com.tgb.oa.web;

    import java.io.IOException;

    import javax.servlet.Filter;
    import javax.servlet.FilterChain;
    import javax.servlet.FilterConfig;
    import javax.servlet.ServletException;
    import javax.servlet.ServletRequest;
    import javax.servlet.ServletResponse;
    import javax.servlet.http.HttpServletRequest;

    import com.tgb.oa.SystemContext;
    /**
     *
     * @oa_02    过滤器,获取相关分页数据.
     * @author   jnqqls
     * @group    TGB
     * @version 1.0
      * @comments
     */
    public class PagerFilter implements Filter {

        public void destroy() {
        }

        public void doFilter(ServletRequest request, ServletResponse response,
                FilterChain chain) throws IOException, ServletException {

            HttpServletRequest httpRequest = (HttpServletRequest)request;
        &n
