I am creating a Spring Boot app with spring data jpa and with the policy persisted in PostgreSQL DB.

Model - I am loading the model in my Main application class inside a Bean

    @Bean
    public Model getModel(){
        Model model = new Model();
        model.addDef("r", "r", "sub, obj, act");
        model.addDef("p", "p", "sub, obj, act");
        model.addDef("g", "g", "_, _");
        model.addDef("e", "e", "some(where (p.eft == allow))");
        model.addDef("m", "m", "g(r.sub, p.sub) && keyMatch2(r.obj, p.obj) && regexMatch(r.act, p.act)");
        return model;
    }

### In my Filter Class, I am doing the following for initializing the Enforcer with the Model and the Policy- 

    @Autowired   
    private Model model;
    @Autowired   
    private HikariDataSource dataSource;

     public void doFilter(...){
               JDBCAdapter adapter = new JDBCAdapter(dataSource);
               Enforcer enforcer = new Enforcer(model, adapter);
               enforcer.addPolicy("sites_apps_admin", "/ws/policymanagement/policy", "POST");
}

### The application starts fine and the table casbin_rule gets created in my postgreSQL DB. But as soon as the code hits the enforcer.addPolicy() line, it throws an exception as follows - 

java.lang.IllegalAccessError: class org.casbin.adapter.JDBCBaseAdapter tried to access private field org.casbin.adapter.CasbinRule.ptype (org.casbin.adapter.JDBCBaseAdapter and org.casbin.adapter.CasbinRule are in unnamed module of loader 'app')

@suryamukerjee1982 The easiest solution is to remove the casbin-spring-boot-starter dependency or jdbc-adapter. Because the CasbinRule structure in casbin-spring-boot-starter and jdbc-adapter is conflicting. And It looks like you don't use casbin-spring-boot-starter at all. Currently casbin-spring-boot-starter has its own built-in jdbc-adapter, but it is not compatible, so you cannot import jdbc-adapter at the same time. This is a legacy problem, and we will fix it later.

@suryamukerjee1982 plz have a try
