很实用的一个ext表格，具有很好的分页功能。

1、写一个bean类:

public class PatroMonitorBean {
private String devicename;
private String actionname;
private String execTime;
private String status;
public String getDevicename() {
	return devicename;
}
public void setDevicename(String devicename) {
	this.devicename = devicename;
}
public String getActionname() {
	return actionname;
}
public void setActionname(String actionname) {
	this.actionname = actionname;
}
public String getExecTime() {
	return execTime;
}
public void setExecTime(String execTime) {
	this.execTime = execTime;
}
public String getStatus() {
	return status;
}
public void setStatus(String status) {
	this.status = status;
}
}

 2、写一个ListRange类：

public class ListRange implements Serializable {
    private Object[] data;
    private int totalSize;

    public ListRange(Object[] data, int totalSize) {
        this.data = data;
        this.totalSize = totalSize;
    }

    public Object[] getData() {
        return data;
    }
    public void setData(Object[] data) {
        this.data = data;
    }

    public int getTotalSize() {
        return totalSize;
    }
    public void setTotalSize(int totalSize) {
        this.totalSize = totalSize;
    }
}

 3、关键类，核心类中的核心方法：sql 语句根据需求

public ListRange getItems(Map conditions) {
		int start = Integer.parseInt(conditions.get("start").toString());
		int pageSize = Integer.parseInt(conditions.get("limit").toString());
		List<PatroMonitorBean> infoList = new ArrayList<PatroMonitorBean>();
		Connection con = null;
		Statement stat = null;
		ResultSet rs = null;
		String sql = "";
		try {
			con = DataService.getConnection();
			stat = con.createStatement();
			sql = " ";
			rs = stat.executeQuery(sql);
			while (rs.next()) {
				PatroMonitorBean pmb = new PatroMonitorBean();
				String devicename=rs.getString(1);
				String actionname=rs.getString(2);
				String execTime=rs.getString(3);
				String status = rs.getString(4);
				pmb.setDevicename(devicename);
				pmb.setActionname(actionname);
				pmb.setExecTime(execTime);
				pmb.setExecTime(execTime.substring(0, 19));
				if (status.equals("10002"))
					status = "异常";
				pmb.setStatus(status);
				if (status.equals("10001"))
					status = "不正常";
				pmb.setStatus(status);
				infoList.add(pmb);
			}

		} catch (Exception e) {
			e.printStackTrace();
		}
		int end = start + pageSize;
		if (end > infoList.size()) {
			end = infoList.size();
		}
		List list = infoList.subList(start, end);
		return new ListRange(list.toArray(), infoList.size());
	}

 4、jsp页面。需要有DWRProxy.js 把给js类库导入到webRoot下。

5、dwr.xml配置有:

<dwr>
	<allow>	
		        <create creator="new" javascript="patrolMonitor"><!--一般写类名-->
				<param name="class" value="类路径"/>
	   	</create>	
        
        <convert converter="bean" match="com.eastcom.action.ListRange"/>
        <convert converter="bean" match="com.eastcom.action.bean类"/>
	</allow>
</dwr>
