怎么获取表的字段名称

[starryd]

在java中，我用以下的方法连接数据库
public class Datacon implements java.io.Serializable{
String UserName;
String PassWord;
Statement stmt = null;
Connection conn=null;
ResultSet rs = null;

Datacon(String username,String password) {
this.UserName=username;
this.PassWord=password;
}

public void connect() throws Exception{
try{
Class.forName("org.gjt.mm.mysql.Driver").newInstance() ;
conn= DriverManager.getConnection("jdbc:mysql://localhost/LZ",UserName,PassWord);
stmt = conn.createStatement();
}catch (java.lang.ClassNotFoundException e)
{

}
}
}
我想获取数据库中表的字段名称。该怎么添加一个函数。

ResultSet rs = ...;
ResultSetMetaData rsmd = rs.getMetaData();
String columnName1 = rsmd.getColumnName(1);

[xiaofenguser]

ResultSetMetaData rsmt = rs.getMetaData();
for (int i = 1; i < rsmt.getColumnCount() + 1; i++)
{
System.out.println(rsmt.getColumnName(i));
}

[希偌]

rs.getMetaData().getColumnName();
