通过JDBC连接到Derby数据库失败

Question

I'm trying to build a simple spring app which needs to have the ability to communicate with a database. Following a tutorial I have completed the entire code of my app however when I run my app I get this:

    Exception in thread "main" java.lang.IllegalStateException: Could not load JDBC driver class [org.apache.derby.jdbc.EmbeddedDruver]
    at org.springframework.jdbc.datasource.DriverManagerDataSource.setDriverClassName(DriverManagerDataSource.java:130)
    at main.Application.main(Application.java:15)
Caused by: java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDruver
    at java.net.URLClassLoader$1.run(Unknown Source)
    at java.net.URLClassLoader$1.run(Unknown Source)

    at java.lang.Class.forName(Unknown Source)
    at org.springframework.jdbc.datasource.DriverManagerDataSource.setDriverClassName(DriverManagerDataSource.java:127)
    ... 1 more

Here is the code which sets the data source and the jdbc:

        DriverManagerDataSource ds = new DriverManagerDataSource();
        ds.setDriverClassName("org.apache.derby.jdbc.EmbeddedDruver");
        ds.setUrl("jdbc:derby:c:\\temp\\database\\test01;create=true");
        ds.setUsername("");
        ds.setPassword("");
        siod.setDataSource(ds);

I used SQuirrel to create my db. I'm 100% certain that is the path. Here is an image which tells what path the db has: http://postimg.org/image/4tbfsxql9/

I'm sure there a simple answer to my question. Thank you.

Answer 1

The correct spelling is "org.apache.derby.jdbc.EmbeddedDriver" not EmbeddedDruver.

If that doesn't fix it, check that you have your classpath set to include the Derby jar(s). This can either be as explained here or by including the Derby jar(s) with other jars in the library of your application.
