dropwizard Cannot create new registration for component type class

[Jason Novotny]

Hi,

I'm new to dropwizard and I'm using the mybatis-dropwizard https://github.com/login-box/dropwizard-mybatis integrtaion which I've modified a bit since I need to access two databases.

My code has the following:

@Override
public void run(T configuration, io.dropwizard.setup.Environment environment) throws Exception {
    ManagedDataSource fooDataSource = buildFooDataSource(configuration, environment);
    ManagedDataSource barDataSource = buildBarDataSource(configuration, environment);

    environment.lifecycle().manage(fooDataSource);
    environment.lifecycle().manage(barDataSource);

    fooSqlSessionFactory = createSqlSessionFactory(fooDataSource);
    barSqlSessionFactory = createSqlSessionFactory(barDataSource);

    environment.healthChecks().register("foo", new SqlSessionFactoryHealthCheck(fooSqlSessionFactory));
    environment.jersey().register(SqlSessionProvider.binder(fooSqlSessionFactory));

    environment.healthChecks().register("bar", new SqlSessionFactoryHealthCheck(barSqlSessionFactory));
    environment.jersey().register(SqlSessionProvider.binder(barSqlSessionFactory));
}

Basically I had just copied lines I found for one DB/SqlSessionfactory for the other.

Now I get an error/warning after the 2nd environment.jersey().register is executed:

WARN  [2016-01-21 19:37:55,529] org.glassfish.jersey.internal.Errors: The following warnings have been detected: WARNING: Cannot create new registration for component type class com.loginbox.dropwizard.mybatis.providers.SqlSessionProvider$Binder: Existing previous registration found for the type.

I'm pretty clueless here, what do I need to register and how?

Thanks, Jason

Hi Jason,

did you solve the problem back then? I get exactly the same message. Pretty annoying, don't know what to do about this.

Thanks in advance!

Hmm,

That was a while back, I don't recall what the solution was. However, I was able to create two database connections with mybatis in the end.
