下面是本人在业余时间搞的框架的简要介绍,无所谓推广,跟大家一起分享和交流
1.可视化代码生成工具,参考界面
基本原理还是从数据库中生成出来,目前支持mysql和Oracle的数据源，支持外键生成many-to-one关系，可以生成元数据，参考下面元数据介绍；
2.元数据
对象的基本属性，合法性和其他的一些扩展属性的描述，生成代码时可以根据数据库的定义生成，如：数据库字段注释，类型等；
可以用来描述界面，获取关联对象等；
3.RBAC的角色权限控制，并集成ACEGI
4.日志，Lucene等等

详细参考开源http://code.google.com/p/whfframework

上述工作完成后，相关的代码简单的表现为：
列表： 
<framework:table pkStyle="checkbox_counter" navPosition="both" queryString="<%= queryString %>">
<framework:caption><span class="whf_object_title"><framework:attr source="STRUTS-META" attr="name" /></span></framework:caption>
</framework:table>


编辑： 
<framework:table pkStyle="" border="1" cellspacing="0" cellpadding="0" navPosition="none" pageSize="1" displayStyle="form" editable="true" useStrutsForm="true" view="SYSTEM-OBJECT-VIEW">
<framework:caption><span class="whf_object_title"><bean:write name="STRUTS-META" property="name" /></span></framework:caption>
</framework:table>


主从表编辑： 
<input type="hidden" name="UPDATING_PROPERTY_NAME" value="properties" />
<html:hidden property="webMethod" />
<framework:table pkStyle="" border="1" cellspacing="0" cellpadding="0" navPosition="none" pageSize="1" displayStyle="form" editable="true" useStrutsForm="true" view="SYSTEM-OBJECT-VIEW">
<framework:caption><span class="whf_object_title"><bean:write name="STRUTS-META" property="name" /></span></framework:caption>
</framework:table>

<framework:table id="ObjectProperty" pkStyle="checkbox_counter" pkSuffix="true" namePrefix="Property" border="1" cellspacing="0" cellpadding="0" boClassName="whf.framework.meta.entity.ObjectProperty"  navPosition="bottom" pageSize="100" editable="true" useStrutsForm="true" dataSourceName=".sortedProperties">
</framework:table>


查看： 
<html:form action="<%=  (String)request.getAttribute(Constants.STRUTS_PATH) %>" method="post">
<html:hidden property="id" />
<html:hidden property="webMethod" />
<framework:table pkStyle="" border="1" cellspacing="0" cellpadding="0" navPosition="none" pageSize="1" displayStyle="form" useStrutsForm="true">
<framework:caption><span class="whf_object_title"><framework:attr source="STRUTS-META" attr="name" /></span></framework:caption>
</framework:table>
<input type='button' onclick='window.history.back()' value='<bean:message key="form.return" />' />
</html:form>


对于真正使用过程可以通过定义公共jsp文件，而对于服务器端都作了第一层封装处理，如果没有特殊处理，你不需要写一行代码；

不错！楼主可以参考我的实现：http://www.iteye.com/topic/232219
另外，能否介绍一下你的代码生成器的设计思路，供大家参考参考！

对于实体，从数据库中的描述即可，如下代码： 
package whf.framework.tools.generator;

import whf.framework.entity.AbstractEntity;
import whf.framework.tools.generator.db.Column;
import whf.framework.tools.generator.db.Table;
import whf.framework.util.BeanUtils;

/**
 * @author wanghaifeng
 *
 */
public class EntityGenerator extends AbstractGenerator {
	private String packageName;

	private String className;

	private String[] props;

	private String[] types;
	
	private Table table;

	public EntityGenerator(String packageName, String className, String[] types, String[] props) {
		this.packageName = packageName;
		this.className = className;
		this.types = types;
		this.props = props;
	}

	public EntityGenerator(String packageName, Table table) {
		this.packageName = packageName;
		this.table = table;
	}

	public String[] getProps(){
		return this.props;
	}
	
	protected void gen() {
		super.setPackageName(this.packageName+".entity");
		super.setSuperClassName(AbstractEntity.class.getName());
		super.setImplementsSerializable(true);
//		super.setInterfaces(new String[]{"I"+this.table.getBoClassName()});
		if(table == null){
			super.setClassName(this.className);
			for (int i = 0; props != null && i < props.length; i++) {
				if(!BeanUtils.hasProperty(AbstractEntity.class, props[i])){
					super.addProp(types[i], props[i],true, true, props[i]);
				}
			}
		} else {
			super.setClassName(table.getBoClassName());
			for(Column col: table.getColumns()){
				String pn = col.getPropertyName();
				if(!BeanUtils.hasProperty(AbstractEntity.class, pn)){
					super.addProp(col.getPropertyType(), col.getPropertyName(), true, true, col.getColumnComment());
//					if(!col.isForeign()){
//						super.addProp(col.getPropertyType(), pn,true, true);
//					}else{
//						String refTableName = col.getReferencedTable();
//						String refBo = Utils.getBoClassName(refTableName, table.getTablePre());
//						String dt = this.packageName+".entity."+refBo;
//						String p = pn;
//						if(p.toLowerCase().endsWith("id")){
//							p = p.substring(0, p.length() - 2);
//						}
//						super.addProp(dt, p, true, true);
//					}
				}
			}
		}
	}

	public static void main(String[] args) throws Exception {

	}
}

对于其他使用模板，如下：
