Thread: java.sql.SQLException: Access denied

I am getting an error from my Spring web application. I am trying to post to my MariaDB database, but I'm getting the following exception.

org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLSyntaxErrorException: Access denied for user 'ghscom_frank'@'localhost' to database 'ghscom_frank'
Model object must not be null

The trouble is that ghscom_root is not the user name I have in my applicationContext.xml. I'm not sure what more information to give, so let me put down a whole lot, and I'm sure if someone needs more they'll ask. Here is the relevant portion of applicationContext.xml.

	<bean id="dataSource"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="com.mysql.cj.jdbc.Driver" />
		<property name="url" value="jdbc:mysql://localhost/ghscom_ghs86" />
		<property name="username" value="ghscom_frank" />
		<property name="password" value="GHSMatadors1986" />
	</bean>

This is from my controller.

	public String writeComment(@ModelAttribute("name") String name,
			@ModelAttribute("comment") String commentString, Model model) {
		Calendar date = Calendar.getInstance();
		Comment comment = new Comment();
		comment.setName(name.trim());
		comment.setComment(prepareCommentForDatabase(commentString));
		comment.setCommentDate(((date.get(Calendar.MONTH) + 1) + "/"
				+ date.get(Calendar.DATE) + "/" + date.get(Calendar.YEAR)));
 
		try {
			commentDAO.writeComment(comment);
			List<Comment> comments = commentDAO.getComments();
			model.addAttribute(comments);
		} catch (Exception e) {
			System.out.println(e.getMessage());
			return "Oops";
		}
 
		return "GuestBook";
	}

This is from my DAO class.

	public boolean writeComment(Comment comment) {
		boolean successfulWrite;
		Calendar date = Calendar.getInstance();
		comment.setName(comment.getName().trim());
		comment.setComment(comment.getComment().trim());
		comment.setCommentDate(((date.get(Calendar.MONTH) + 1) + "/"
				+ date.get(Calendar.DATE) + "/" + date.get(Calendar.YEAR)));
 
		try {
			this.getJdbcTemplate().update(
					"insert into comments(comment_date, name, comment) values ('"
							+ comment.getCommentDate() + "', '" + comment.getName()
							+ "', '" + comment.getComment() + "')");
 
			successfulWrite = true;
		} catch (Exception e) {
			System.out.println(e.toString());
			successfulWrite = false;
		}
 
		return successfulWrite;
	}

I have also tried granting privilege to the correct user, but I get the following:

MariaDB [(none)]> grant all on ghscom_ghs86 to ghscom_frank;
ERROR 1046 (3D000): No database selected
