java实体类生成工具

前言

原因是这样的，eclipse有那种生成实体类的插件，可是我感觉装来装去很麻烦，于是我想，干脆自己做一个生成实体类的工具吧，说做就做，然后就自己花了两个小时左右做出来了一个，以后应该能大大提高工作效率吧。

实现方法

输入：属性个数
输入：type virableName
输出：d盘下面的example文件，该文件里面生成了实体类的代码

原理就是填充数据而已。。。根本没有难度
然后用了map模板把数据存起来了

使用截图

**这个是数据截图，CKCommand表示类，5表示有几个属性，剩下的都是数据属性
然后把这个数据复制进控制台运行就可以了**

运行截图

最后的实体类截图

注意去D盘下面找

代码

#include <iostream>
#include <string>
#include <map>
#include <fstream>
using namespace std;
int main()
{
int num;  //总体的成员个数
string  which1, Vname,classname;
map<string, string > mapStudent;    //这个我服了
map <string, string >::iterator m1_Iter;
cin >> classname;
cin >> num;
for (int i = 0; i<num; i++){
cin >> which1 >> Vname;

        mapStudent[Vname] = which1;

    }

cout << "Congratulation that you are success!"<<endl;

    ofstream examplefile("d:\\example.txt");
if (examplefile.is_open())
    {
        examplefile << "class "<<classname<<" implements Serializable{\n\n";
for (m1_Iter = mapStudent.begin(); m1_Iter != mapStudent.end(); m1_Iter++){
//cout << "diyige " << m1_Iter->first << " " << m1_Iter->second.first << " " << m1_Iter->second.second << endl;
            examplefile <<" private "<< m1_Iter->second << " " << m1_Iter->first <<";\n";
        }

//first constructor
        examplefile << "\n//无参数的构造器\n";
        examplefile << " public " << classname << "(){\n";
        examplefile << "\n";
        examplefile << " }\n\n";

//第二个构造器
        examplefile << "//有参数的构造器\n";
        examplefile << " public " << classname << "(";   //打印到括号地方了
for (m1_Iter = mapStudent.begin(); m1_Iter != mapStudent.end(); m1_Iter++){
if (m1_Iter != mapStudent.end()){
                examplefile << m1_Iter->second << " " << m1_Iter->first << ",";
            }
else{
                examplefile << m1_Iter->second << " " << m1_Iter->first;
            }
        }
        examplefile << "){\n";
//构造函数里面的内容
for (m1_Iter = mapStudent.begin(); m1_Iter != mapStudent.end(); m1_Iter++){
//examplefile << m1_Iter->second.first << " " << m1_Iter->second.second << ",";
            examplefile << " this." << m1_Iter->first << " = " << m1_Iter->first << ";\n";

        }
        examplefile << " }\n";
//----------------------------- 构造函数内容结束---------------------------------

//----------------------------- get方法开始--------------------------------------
        examplefile << "\n//GET跟SET方法都在这里\n";
for (m1_Iter = mapStudent.begin(); m1_Iter != mapStudent.end(); m1_Iter++){
//examplefile << m1_Iter->second.first << " " << m1_Iter->second.second << ",";
//examplefile << "this." << m1_Iter->second.second << " = " << m1_Iter->second.second << "\n";
            examplefile << " public " << m1_Iter->second << " Get" << m1_Iter->first << "(){\n";
            examplefile << " return " << m1_Iter->first << ";\n";
            examplefile << " }\n\n";

//--------------------------------set方法继续--------------------------------
            examplefile << " public void Set" << m1_Iter->first << "(" << m1_Iter->second << " " << m1_Iter->first\
                << "){\n";
            examplefile << " this." << m1_Iter->first << "=" << m1_Iter->first<< ";\n";
            examplefile << " }\n\n";

        }

//完结撒花
        examplefile << "}\n";



        examplefile.close();
    }

    system("pause");
return 0;
