• @闲.大赋 你好，想跟你请教个问题：

上一期问题http://www.oschina.net/question/146876_227312

您好 根据你的提示还有网上资料参考 现在还有其他几个问题，我先放上代码

SqlQueryListTag ->registerTag("SqlQueryList",SqlQueryListTag.class);

import java.util.List;

import javax.servlet.http.HttpServletRequest;
import net.zhuawa.util.btltag.pojo.ParamSql;
import org.beetl.core.BodyContent;
import org.beetl.core.GeneralVarTagBinding;
import com.jfinal.plugin.activerecord.Db;
import com.jfinal.plugin.activerecord.Record;

public class SqlQueryListTag extends GeneralVarTagBinding {
	
	private String sql;
	private String attribute;
	private Integer pagesize;
	
	public void init(){
		String _sql = getAttributeValue("sql") != null ? getAttributeValue("sql").toString() :null;
		String _attribute = getAttributeValue("attribute") != null ? getAttributeValue("attribute").toString() :null;
		Integer _pagesize = getAttributeValue("pagesize") != null ? Integer.parseInt(getAttributeValue("pagesize").toString()) :0;
		setSql(_sql);
		setAttribute(_attribute);
		setPagesize(_pagesize);
	}
	
	@Override
	public void render() {
		init();
		BodyContent bodyContent = getBodyContent();
		ParamSql paramSql = MessageUtil.parseXml(bodyContent.getBody(),"param");
		String paramSqls = "";
		Object[] paramVaues = new Object[]{};
		if(null != paramSql){
			paramSqls = paramSql.getSql();
			paramVaues = paramSql.getObjects().length > 0 ? paramSql.getObjects() : paramVaues;
		}
		List<Record> queryList = Db.find(new StringBuilder(sql).toString().replace(":paramSql",paramSqls),paramVaues);
		
		HttpServletRequest request =  (HttpServletRequest)ctx.getGlobal("request");
		request.setAttribute("queryList", queryList);
		
//		this.binds(queryList);
//		this.doBodyRender();
//		int size = queryList.size();
//		if(size > 0){
//			for (int i = 0; i < size; i++) {
//				this.binds("index",i);
//				this.binds(queryList.get(i).getColumns(),i);
//				this.doBodyRender();
//			}
//		}
		
	}
	
	public String getSql() {
		return sql;
	}
	public void setSql(String sql) {
		this.sql = sql;
	}
	public String getAttribute() {
		return attribute;
	}
	public void setAttribute(String attribute) {
		this.attribute = attribute;
	}
	public Integer getPagesize() {
		return pagesize;
	}
	public void setPagesize(Integer pagesize) {
		this.pagesize = pagesize;
	}
}

<#SqlQueryList sql="select top 5 * from [Article] where info = '002' :paramSql  order by  time desc,order asc" pagesize="15";list>
            <ParamSql>
                <param sql = " and 1 = 1"  />
            </ParamSql>
               <%
            for(entity in list){
            %>
            <a>标题</a>：
            <%}%>
</#SqlQueryList>

还有一个问题这个标签获取标签体的body（

bodyContent.getBody()

如果要组织html代码的话（以上html代码处

<a>标题</a>：

<#SqlQueryList sql="select top 5 * from [Article] where info = '002' :paramSql  order by  time desc,order asc" pagesize="15" ;list>
            <ParamSql>
                <param sql = " and 1 = 1"  />
            </ParamSql>
</#SqlQueryList>
<%
   for(entity in list){
%>
  <a>标题</a>：
<%}%>
