  <artifactId>jdbc-adapter</artifactId>
  <version>1.1.2-FIX</version>
</dependency>

Simple Example

package com.company.test;

import org.casbin.jcasbin.main.Enforcer;
import org.casbin.jcasbin.util.Util;
import org.casbin.adapter.JDBCAdapter;

public class Test {
    public static void main() {
        // Initialize a JDBC adapter and use it in a jCasbin enforcer:
        // The adapter will use the MySQL database named "casbin".
        // If it doesn't exist, the adapter will create it automatically.
        JDBCAdapter a = new JDBCAdapter("com.mysql.cj.jdbc.Driver", "jdbc:mysql://localhost:3306/", "root", "123"); // Your driver and URL. 

        // Or you can use an existing DB "abc" like this:
        // The adapter will use the table named "casbin_rule".
        // If it doesn't exist, the adapter will create it automatically.
        // JDBCAdapter a = new JDBCAdapter("com.mysql.cj.jdbc.Driver", "jdbc:mysql://localhost:3306/casbin", "root", "123", true);

        Enforcer e = new Enforcer("examples/rbac_model.conf", a);

        // Load the policy from DB.
        e.loadPolicy();

        // Check the permission.
        e.enforce("alice", "data1", "read");

        // Modify the policy.
        // e.addPolicy(...);
        // e.removePolicy(...);

        // Save the policy back to DB.
        e.savePolicy();
    }
}
