Java 从Eclipse访问Wamp服务器数据库
我想使用Java访问我计算机中的Wamp服务器数据库。我的代码如下:Java 从Eclipse访问Wamp服务器数据库,java,mysql,eclipse,connection,Java,Mysql,Eclipse,Connection,我想使用Java访问我计算机中的Wamp服务器数据库。我的代码如下: public static void main(String[] args) { try { // create our mysql database connection String myDriver = "com.mysql.jdbc.Driver"; String myUrl = "jdbc:mysql://
public static void main(String[] args)
{
try
{
// create our mysql database connection
String myDriver = "com.mysql.jdbc.Driver";
String myUrl = "jdbc:mysql://localhost:3306/deneme";
Class.forName(myDriver);
Connection conn = DriverManager.getConnection(myUrl, "root", "");
// our SQL SELECT query.
// if you only need a few columns, specify them by name instead of using "*"
String query = "SELECT * FROM users";
// create the java statement
Statement st = conn.createStatement();
// execute the query, and get a java resultset
ResultSet rs = st.executeQuery(query);
// iterate through the java resultset
while (rs.next())
{
int id = rs.getInt("id");
String firstName = rs.getString("first_name");
String lastName = rs.getString("last_name");
Date dateCreated = rs.getDate("date_created");
boolean isAdmin = rs.getBoolean("is_admin");
int numPoints = rs.getInt("num_points");
// print the results
System.out.format("%s, %s, %s, %s, %s, %s\n", id, firstName, lastName, dateCreated, isAdmin, numPoints);
}
st.close();
}
catch (Exception e)
{
System.err.println("Got an exception! ");
System.err.println(e.getMessage());
}
在此之后,它会给我以下错误:
Got an exception!
com.mysql.jdbc.Driver
如何将自己计算机中的数据库连接到java?
谢谢。尝试将mysql-connector-java-xxxx-bin.jar添加到
/lib
文件夹中。您可以从下载。
然后右键单击p
项目属性
-->Java构建路径
-->外部jar
检查是否在类路径中添加了驱动程序?
