private String passwd = "****";

//========查询

public ResultSet queryExecute(String sql, String []paras)

{

try {

//========1、加载驱动

Class.forName(driver);

//========2、连接

ct = DriverManager.getConnection(url, user, passwd);

//========3、创建PreparedStatement

ps = ct.prepareStatement(sql);

//========4、给问号赋值

if(paras != null) {

for(int i = 0; i < paras.length; i++) {

ps.setString(i + 1, paras[i]);

}

//========5、执行

rs = ps.executeQuery();

} catch (Exception e) {

// TODO: handle exception

e.printStackTrace();

} finally {

//this.close();

}

//========返回值

return rs;

}

//========增删改

public boolean cudExecute(String sql, String []paras)

{

boolean b = true;

try {

//========1、加载驱动

Class.forName(driver);

//========2、连接

ct = DriverManager.getConnection(url, user, passwd);

//========3、创建PreparedStatement

ps = ct.prepareStatement(sql);

//========4、给问号赋值

for(int i = 0; i < paras.length; i++) {

ps.setString(i + 1, paras[i]);

}

//========5、执行

if(ps.executeUpdate() != 1) b = false;

} catch (Exception e) {

// TODO: handle exception

b = false;

e.printStackTrace();

} finally {

this.close();

}

//========返回值

return b;
