Question

我遇到了一个关于Spring启动的非常奇怪的现象，并使用mysql存储数据，今天在我的私人计算机上我git克隆了我正在开发的项目。在eclipse中运行入口主类时，它会抛出异常

2015-11-15 18:28:08.912 ERROR 9183 --- [  restartedMain] o.a.tomcat.jdbc.pool.ConnectionPool      : Unable to create initial connections of pool.

它的application.properties：

spring.datasource.url = jdbc:mysql://localhost:3306/foo?useUnicode=true&characterEncoding=utf8

spring.datasource.username = root
spring.datasource.password = 123456

但我可以直接在终端登录mysql，见下文：

mysql -hlocalhost -uroot -p123456
Warning: Using a password on the command line interface can be insecure.
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 50
Server version: 5.6.27-0ubuntu0.14.04.1 (Ubuntu)

我甚至在同一个项目中编写了一个示例java代码来测试与本地mysql服务器的连接，

public static void main(String[] args) throws SQLException {
    String url = "jdbc:mysql://localhost:3306/foo?useUnicode=true&characterEncoding=utf8";
    String user = "root";
    String password = "123456";
    Connection connection = DriverManager.getConnection(url , user  , password);
    System.out.println(connection);
    Statement stat = connection.createStatement();
    ResultSet rs = stat.executeQuery("select version()");
    rs.next();
    System.out.println(rs.getString(1));
}

运行它有正常输出：

com.mysql.jdbc.JDBC4Connection@48cf768c
5.6.27-0ubuntu0.14.04.1

那么为什么spring-boot无法连接到本地mysql服务器，但其他方式可以吗？

为什么spring-boot无法连接到本地mysql服务器（用户访问被拒绝＆＃39; @＆＃39; localhost＆＃39;（使用密码：是））
