java.sql.SQLException：对用户'sa'@'localhost'拒绝访问（使用密码：NO）

Question

应用程序未选择用户名和密码：

我在java web应用程序中使用Spring 4和Hibernate 4。我的application.properties文件包含以下条目：

#Database related properties
database.driverClassName=com.mysql.jdbc.Driver
database.url=jdbc:mysql://127.0.0.1:3306/xyz
database.username=root
database.password=root@1234

#Hibernate related properties
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.format_sql=true

和我的servlet.xml文件如下：

我使用'root'和'root @ 1234'作为用户名和密码来访问我的数据库。用户root具有我的数据库所需的所有权限。

堆栈跟踪如下：

我尝试对值进行硬编码，但这也没有用。 我无法理解它作为用户使用“sa”的位置（我假设它是hibernate采用的默认值）。 请帮助我理解和解决问题。

谢谢。

编辑1：我知道堆栈溢出有很多这样的问题，但它们都与特权有关。我问的问题是“用户”没有权限，但在这种情况下，它没有获取属性文件提供的值。
