今天在对一个表生成映射文件的时候,都出现“generating artifacts"的问题，查看workspace\.metadata\.log，会发现错误原因：
org.hibernate.exception.GenericJDBCException: Getting database metadataat org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:103)at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:91)at org.hibernate.cfg.reveng.dialect.AbstractMetaDataDialect.getMetaData(AbstractMetaDataDialect.java:64)at org.hibernate.cfg.reveng.dialect.AbstractMetaDataDialect.caseForSearch(AbstractMetaDataDialect.java:163)at org.hibernate.cfg.reveng.dialect.JDBCMetaDataDialect.getTables(JDBCMetaDataDialect.java:22)at org.hibernate.cfg.reveng.JDBCReader.processTables(JDBCReader.java:476)at org.hibernate.cfg.reveng.JDBCReader.readDatabaseSchema(JDBCReader.java:74)at com.genuitec.eclipse.hibernate.wizards.MEJDBCMetaDataConfiguration$1.readDatabaseSchema(MEJDBCMetaDataConfiguration.java:104)at org.hibernate.cfg.JDBCBinder.readFromDatabase(JDBCBinder.java:89)at com.genuitec.eclipse.hibernate.wizards.MEJDBCMetaDataConfiguration.readFromJDBC(MEJDBCMetaDataConfiguration.java:137)at com.genuitec.eclipse.hibernate.wizards.GenerateArtifactsJob$7.execute(GenerateArtifactsJob.java:877)at org.hibernate.console.execution.DefaultExecutionContext.execute(DefaultExecutionContext.java:65)at org.hibernate.console.ConsoleConfiguration.execute(ConsoleConfiguration.java:91)at com.genuitec.eclipse.hibernate.wizards.GenerateArtifactsJob.buildConfiguration(GenerateArtifactsJob.java:858)at com.genuitec.eclipse.hibernate.wizards.GenerateArtifactsJob.run(GenerateArtifactsJob.java:405)at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)Caused by: java.sql.SQLException: Access denied for user’root’@’localhost'(using password: YES)at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1074)at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:4096)at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:4028)at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:919)at com.mysql.jdbc.MysqlIO.proceedHandshakeWithPluggableAuthentication(MysqlIO.java:1694)at com.mysql.jdbc.MysqlIO.doHandshake(MysqlIO.java:1244)at com.mysql.jdbc.ConnectionImpl.coreConnect(ConnectionImpl.java:2412)at com.mysql.jdbc.ConnectionImpl.connectOneTryOnly(ConnectionImpl.java:2445)at com.mysql.jdbc.ConnectionImpl.createNewIO(ConnectionImpl.java:2230)at com.mysql.jdbc.ConnectionImpl.<init>(ConnectionImpl.java:813)at com.mysql.jdbc.ConnectionImpl.getInstance(ConnectionImpl.java:395)at com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:334)at org.hibernate.console.FakeDelegatingDriver.connect(FakeDelegatingDriver.java:40)at java.sql.DriverManager.getConnection(Unknown Source)at java.sql.DriverManager.getConnection(Unknown Source)at org.hibernate.connection.DriverManagerConnectionProvider.getConnection(DriverManagerConnectionProvider.java:110)at org.hibernate.cfg.reveng.dialect.AbstractMetaDataDialect.getConnection(AbstractMetaDataDialect.java:122)at org.hibernate.cfg.reveng.dialect.AbstractMetaDataDialect.getMetaData(AbstractMetaDataDialect.java:61)… 13 more
解决方案：
关闭MyEclipse,重新启动一下，然后再做一次数据库表的映射就没问题了。
