我连接数据库出现这种问题，求解决啊

java.sql.SQLException: The connection property 'useUnicode' only accepts values of the form: 'true', 'false', 'yes' or 'no'. The value 'ture' is not in this set.

老兄,true写反了吧

这是测试代码：package util;

import java.sql.Connection;
import java.sql.DriverManager;

public class DB {
private static final String driver = "com.mysql.jdbc.Driver";
private static final String url = "jdbc:mysql://localhost:3306/user?useUnicode=ture&characterEncoding=UTF";
private static final String username="uroot";
private static final String password="root";

private static Connection conn = null;




static{
    try
    {
        Class.forName(driver);
    }
    catch(Exception ex)
    {
        ex.printStackTrace();
    }
}
public static Connection getConnection() throws Exception
{
    if(conn==null)
    {
        conn= DriverManager.getConnection(url, username, password);
        return conn;
    }
    return conn;            
}

public static void main(String[] a)
{
    try
    {
    Connection conn = DB.getConnection();
if(conn!=null)
{
    System.out.println("数据库连接正常！");

}else{
    System.out.println("数据库连接YI常！");

}
    }
    catch(Exception ex)
    {
        ex.printStackTrace();
    }
}

}

ture ==> true
如果没用，那就清理下缓存再试试

数据库字段有限制，只能是true，false什么的，现在里面有ture这个值，修改下

characterEncoding=utf8 少了个8

&

确认写法没错看看链接符有没有空格如useSSL=false&characterEncoding=UTF-8 &后面不能有空格
