dwr <convert converter="bean" match=""/>注意事项

1、后台dwr.xml配置

<!-- 菜单管理 -->
<convert converter="bean" match="com.dreamoa.domain.Menu"/>
<create creator="new" javascript="MenuManager">
 <param name="class">com.dreamoa.dwrservice.menuMgr.MenuMgr</param>
      <include method="addMenu"/>
</create>

2、Menu.java

package com.dreamoa.domain;
/**
 * 菜单
 * @author 忧里修斯
 */
public class Menu {
	
	private String idno;
	private String img;
	private String name;
	private String url;
	private String parentid;
	private String sort;
	private String oper;
	
	//getter and setter
	public String getIdno() {
		return idno;
	}
	public void setIdno(String idno) {
		this.idno = idno;
	}
	public String getImg() {
		return img;
	}
	public void setImg(String img) {
		this.img = img;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getUrl() {
		return url;
	}
	public void setUrl(String url) {
		this.url = url;
	}
	public String getParentid() {
		return parentid;
	}
	public void setParentid(String parentid) {
		this.parentid = parentid;
	}
	public String getSort() {
		return sort;
	}
	public void setSort(String sort) {
		this.sort = sort;
	}
	public String getOper() {
		return oper;
	}
	public void setOper(String oper) {
		this.oper = oper;
	}
}

3、业务类 MenuMgr.java

package com.dreamoa.dwrservice.menuMgr;

import org.apache.log4j.Logger;

import com.dreamoa.domain.Menu;
import com.dreamoa.sys.BaseDAO;
import com.dreamoa.util.RandomUtil;

/**
 * 实现菜单的增、删、改操作
 * @author 忧里修斯
 */
public class MenuMgr extends BaseDAO<Menu>{
	
	Logger log = Logger.getLogger(MenuMgr.class);
	
	/**
	 * 增加菜单
	 * @param menu
	 */
	public void addMenu(Menu menu){
		menu.setIdno(RandomUtil.GenPrimaryKey());
		beginTransaction();
		save(menu);
		commit();
	}
}

4、前台的js

/**
* 提交增加菜单表单
 */
addMenu:function(){
    var Menu = {};
    Menu = Ext.dao.getObjFromForm(menuForm);
    MenuManager.addMenu(Menu);
}

特注：此处的js对象Menu中必须包含的属性必须与po Menu.java中的属性完全相同，如Menu.java中有属性idno,则js对象Menu中也必须有属性id即Menu.idno。若js中的属性有为空的，则转化后的java类Menu相应的属性页为空。
