struts2.2.1中运用action类时遇到的奇怪现象~~汗~

来源：互联网发布：怎么看算法导论这本书编辑：程序博客网时间：2024/05/21 06:27

CategoryAction.action代码如下

package com.itnetwork.Action;import java.util.ArrayList;import java.util.Iterator;import java.util.List;import javax.annotation.Resource;import net.sf.json.JSONArray;import org.springframework.context.annotation.Scope;import org.springframework.stereotype.Component;import com.itnetwork.Entity.Category;import com.itnetwork.ServiceImp.CategoryServiceImp;import com.opensymphony.xwork2.ActionSupport;@Component("categoryAction")@Scope("prototype")public class CategoryAction extends ActionSupport{//private List<Category> categoryList=new ArrayList<Category>();//private List<Object[]> comboboxModel;private String comboboxModelSt;private int cId;private CategoryServiceImp categoryServiceImp;public String CategoryList(){List<Object[]> comboboxModel=categoryServiceImp.getComboboxModel();JSONArray jsonArray = JSONArray.fromObject(comboboxModel);comboboxModelSt=jsonArray.toString();System.out.println(comboboxModelSt);return this.SUCCESS;}/*public List<Object[]> getComboboxModel() {return comboboxModel;}public void setComboboxModel(List<Object[]> comboboxModel) {this.comboboxModel = comboboxModel;}*/public String getComboboxModelSt() {return comboboxModelSt;}public void setComboboxModelSt(String comboboxModelSt) {this.comboboxModelSt = comboboxModelSt;}/*public int getCId() {return cId;}public void setCId(int cId) {this.cId = cId;}*/public CategoryServiceImp getCategoryServiceImp() {return categoryServiceImp;}public int getcId() {return cId;}public void setcId(int cId) {this.cId = cId;}@Resource(name="categoryServiceImp")public void setCategoryServiceImp(CategoryServiceImp categoryServiceImp) {this.categoryServiceImp = categoryServiceImp;}}

我的jsp页面：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><%@ taglib uri="/struts-tags" prefix="s"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <base href="<%=basePath%>"> <title>二级栏目列表</title> </head> <body><s:property value="comboboxModelSt"/><s:debug></s:debug></body></html>

浏览器错误信息如下（部分）：

以上错误根据输出的信息看，个人认为是找不到cId属性，晕死！怎么会找不到呢？有get，set方法（方法是我用myeclipse8.5自动生成的，可他妈的怎么就给我生成getcId（），setcId（），而不是生成getCId（）呢？错误就是因为这），

我把它手动改成getCId形式，就好了！但是又有个问题出现！我百思不得其解，所以特以此记录下来，等以后再分析分析！

在前台看debug信息，信息如下（我已经把getcId改成getCId形式，set也是）：

[[13,"category11"],[14,"category12"],[15,"category13"],[18,"category11"],[19,"category12"],[20,"category13"]] [Debug]

我的疑惑！comboboxModelSt怎么就会是头字母小写，但对比CId，从上面看CId属性，怎么就不是cId属性呢？？
后来我把属性cId改成cid，就是不要首字母小写，接着大写这种形式命名属性，然后用myeclipse8.5自动生成，结果正常，生成的get，set方法也正常（getCid）
前台查看debug信息，属性名也正常（cid）！
暂时还没解决这个疑惑！先总结，定义属性事，不要在第二个字母用大写这形式！
