kingbasejdbc4 not found inspringboot

The "kingbasejdbc4 not found" error indicates that Spring Boot is unable to find the required dependency for Kingbase JDBC driver in your project.

To resolve this issue, you can try the following steps:

1. Ensure that you have added the Kingbase JDBC driver dependency in your project's pom.xml file. You can find the dependency information on the Kingbase website.

2. Check that the dependency version in the pom.xml file matches the version of the Kingbase JDBC driver that you have downloaded.

3. If you have already added the dependency, try deleting the existing dependency from your local repository and re-downloading it.

4. Check that the dependency scope is set to "runtime" or "compile" in the pom.xml file.

5. If you are using Spring Boot 2.x, you can try adding the following dependency in your pom.xml file:

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.9</version>
</dependency>

This should automatically configure the Kingbase JDBC driver for you.

I hope this helps you resolve the issue. Let me know if you have any further questions!
