Java MySQL:用户的访问被拒绝。。。使用密码：是

由于最近重新格式化了硬盘，我的本地Java/Tomcat/MySQL堆栈无法正常工作

这是一个干净的MySQL安装，运行在MacOSX10.7.3（Lion）上

我遇到的错误是，当我的tomcat实例启动并尝试连接时：

SEVERE: Servlet /concorde-web threw load() exception
java.sql.SQLException: Access denied for user 'concorde'@'localhost' (using password: YES)
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1073)

采取的步骤：

• 我已经设置了

  concorde@localhost

  的密码（如所述）和
• 我可以使用相同的凭据从控制台进行连接。所有以下工作：

  mysql -u concorde -h localhost -p
  mysql -u concorde -p
  mysql -u concorde -h localhost -D concorde -p
  // the app is trying to connect as user concorde to db concorde
  

• 我已确保concorde用户拥有权限-不仅来自localhost，还来自任何地方：

  GRANT ALL ON concorde.* TO 'concorde'@'%';
  FLUSH PRIVELEDGES;
  

我错过了什么

除此之外，我还可以采取什么措施来了解这里发生了什么？我可以查一下日志吗

编辑 根据要求，这是我正在使用的代码

然而，这段代码在重新格式化硬盘之前运行良好，所以我怀疑问题是否出在它里面

该应用程序在spring容器中运行，而在spring启动期间，一切都会出现问题

以下是相关的bean声明：

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="persistenceUnitName" value="spring-jpa" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="showSql" value="true" />
            <property name="generateDdl" value="false" />
            <property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect" />
        </bean>
    </property>
</bean>


<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url"
        value="jdbc:mysql://${database.host}:${database.port}/${database.name}" />
    <property name="username" value="${database.username}" />
    <property name="password" value="${database.password}" />
    <property name="initialSize" value="5" />
    <property name="maxActive" value="50" />
</bean>

此外，以下是权限查询的（节略）输出：

mysql> select * from information_schema.user_privileges;

| 'concorde'@'localhost'                 | def           | USAGE                   | NO           |

注意-这是通过使用

root登录运行的

我怀疑那里显示的
NO
中有我的用户的线索，但我不确定如何解释这些数据

由于您似乎可以使用来自命令行的预期凭据登录，因此我怀疑您的属性是否被正确地替换到了“dataSource”bean中

尝试暂时硬编码数据源bean的所有参数。
如果这样做有效，则不会设置您的属性。
令人尴尬的是，答案是密码是从外部文件读入的

其他人签出了该文件，提交该文件时，密码中附加了一些尾随的空格字符。当spring读取属性文件时，似乎没有修剪这些属性（我想这是合理的）

然而，这就是问题的根源。一个真正错误的密码。
我的MySQL错误日志在
MySQL/data/MySQL\u error.log
中。查看它（文件名可能有点不同），您可能会在那里找到更多详细信息（尽管我对此表示怀疑…）。你能提供一段你试图连接的代码吗？你的jdbc url格式正确吗？我最好的猜测是你的参数在java代码中被颠倒了，请发布代码。你能用这个命令连接吗
mysql-u concorde-h 127.0.0.7-p
我对您所说的内容知之甚少，但我注意到他们正在使用一个不同的类（org.springframework.jdbc.datasource.drivermanagedatasource）作为数据源。抱歉，如果这不相关的话，我只是想了解一下这个问题并注意到它。在阅读这篇文章之前，我花了一天时间来解决这个问题。我在那里断线了。两台计算机之间的同步导致了某种原因。我也有一个类似的错误。在阅读了这个答案之后，我几乎没有注意到，由于服务器的特殊字体，在配置中，密码是用“1”而不是“l”写的
