JDK1.5中添加enum类与数据库表进行映射

public enum UserUser { 
username, 
id; 
}

public class UserTest { 
public static void main(String [] args) 
{ 
//构建SQL语句 
  String sql="select * from "+UserUser.class.getSimpleName() +
" where "+UserUser.username.toString()+"=aksdkk"; 
System.out.println(sql); 
} 
}

package com.myorm.test; 
import com.tables.models.IDbTable; 
import com.tables.models.SqlType; 
public enum UserUser implements IDbTable{ 
/** 
* <b>说明:</b>用户名<br/> 
* <b>类型:</b>varchar<br/> 
* <b>长度:</b>10<br/> 
* <b>精度:</b>0<br/> 
* <b>是否允许空</b>:否<br/> 
*/ 
username{ 
/** 
* 如果字段名做了更改,只要更改此函数的返回值就可以了 
*/ 
public String toString(){ 
return "User_Name"; 
} 
public SqlType getSqlType() 
{ 
return SqlType.STRING; 
} 
}, 
id 
{ 
public SqlType getSqlType() 
{ 
return SqlType.STRING; 
} 
}; 
/** 
* 获取主键列 
* @return 返回主键列 
*/ 
public static UserUser getIdCol() 
{ 
return id; 
} 
/** 
* ID 生成器 
* 在MySQL中如果用UUID()生成主键,那返回"UUID()"; 
* 在Oracle中如果用SEQUENCE生成主键,返回"SEQUENCE_NAME.NEXTVAL" 
* @return 
*/ 
public static String idGenerator() 
{ 
return "uuid()"; 
} 
public static String getInsertSQL() 
{ 
StringBuffer insert=new StringBuffer(); 
insert.append("insert into ").append(UserUser.class.getSimpleName()); 
insert.append(" (").append(id).append(",").append(username).append(") values ("); 
insert.append(idGenerator()).append(",?)"); 
return insert.toString(); 
} 
}
