Question

开始我进入mysql建表的时候一直报错密码不对什么的，我就使用的匿名登录，没有用密码登陆进去了，但是写JDBC程序的时候要连接mysql，程序报错如下：（PS：应该怎么解决呢？急求！！） java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:964) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3970) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3906) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:873) at com.mysql.jdbc.MysqlIO.secureAuth411(MysqlIO.java:4417) at com.mysql.jdbc.MysqlIO.doHandshake(MysqlIO.java:1278) at com.mysql.jdbc.ConnectionImpl.coreConnect(ConnectionImpl.java:2253) at com.mysql.jdbc.ConnectionImpl.connectOneTryOnly(ConnectionImpl.java:2284) at com.mysql.jdbc.ConnectionImpl.createNewIO(ConnectionImpl.java:2083) at com.mysql.jdbc.ConnectionImpl.<init>(ConnectionImpl.java:806) at com.mysql.jdbc.JDBC4Connection.<init>(JDBC4Connection.java:47) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:408) at com.mysql.jdbc.Util.handleNewInstance(Util.java:425) at com.mysql.jdbc.ConnectionImpl.getInstance(ConnectionImpl.java:410) at com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:328) at java.sql.DriverManager.getConnection(DriverManager.java:664) at java.sql.DriverManager.getConnection(DriverManager.java:247) at TestJDBC.main(TestJDBC.java:16)
