Java Web连接各种数据库方式汇总

1.Oracle数据库（thin模式）

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();

String url="jdbc:oracle:thin:@localhost:1521:orcl";//orcl为数据库的SID

String user="test";

String password="test";

Connection conn = "DriverManager.getConnection(url,user,password)";

2.DB2 数据库

Class.forName("com.ibm.db2.jdbc.app.DB2Driver").newInstance();

String url="jdbc:db2://localhost:5000/sample";simple 为你的数据库名

String user="admin";

String password="";

Connection conn=DriverManager.getConnection(url,user,password);

3.Sql Server 数据库

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();

String url="jdbc.microsoft:sqlserver://localhost:1433;DatabaseName=mydb";//mydb为数据库

String user="sa";

String password="123456";

Connnection conn=DriverManager.getConnection(url,user,password);

4.Sybase 数据库

Class.forName("com.sybase.jdbc.SybDriver").newInstance();

String url="jdbc:sybase:Tds:localhost:5007/myDB";//myDB为你的数据库名

Properties sysProps = System.getProperties();

SysProps.put("user","userid");

SysProps.put("password","user_password");

Connection conn = DriverManager.getConnection(url,SysProps);

5.Informix 数据库

Class.forName("com.informix.jdbc.IfxDriver").newInstance();

String url="jdbc:informix-sqli://ip地址/myDB:INFORMIXSERVER=myserver;user=testuser;password=testpassword";

Connection conn=DriverManager.getConnection(url);

6.MySQL数据库

Class.forName('org.git.mm.mysql..Driver').newInstance();

String url="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=truecharacterEncoding=8859_1";//myDB为数据库名

Connection conn=DriverManager.getConnection(url);

7.access数据库

Class.forName("sum.jdbc.odbc.JdbcOdbcDriver");

String url="jdbc:odbc:Driver={Microsoft Access Driver(*.mdb)};DBQ="+application.getRealPath("/Data/ReportDemo.mdb");

Connection conn = DriverManager.getConnection(url,"","");

操作数据库方法

String sql=" ";

Statement st=conn.createStatement();

ReusltSet rs=st.executeQuery(sql);
