Destroying Beans

tip

Only singleton objects support destruction.

Method One

Use the net.hasor.core.Destroy or javax.annotation.PreDestroy annotation.

Use @Singleton together with @Destroy. After the bean is created, Hasor tracks it automatically. When the Hasor container enters the destroy process, Hasor calls the destroy method automatically:

@Singleton
public class PojoBean {
    @Destroy
    public void destroy(){
        ...
    }
}

public class MyModule implements Module {
    public void loadModule(ApiBinder apiBinder) throws Throwable {
        apiBinder.bindType(PojoBean.class);
    }
}

Method two:

The corresponding ApiBinder method is destroyMethod. Specify it in code during module initialization, as shown below:

public class PojoBean {
    public void destroy(){
        ...
    }
}

public class MyModule implements Module {
    public void loadModule(ApiBinder apiBinder) throws Throwable {
        apiBinder.bindType(PojoBean.class)
                .destroyMethod("destroy") // Destroy method, equivalent to @Destroy.
                .asEagerSingleton();      // Singleton, equivalent to @Singleton.
    }
}
