3 Spring Integration

Some of your beans may contain state that needs to be unique per tenant. A good example of this might be a bean that contains a cache, where they key in the cache would result in collisions if it were shared among all tenants.

With this plugin, you can write the beans as if they are for only one tenant, and the plugin will manage a copy of the bean for each tenant for you and make sure the correct instance is used in the appropriate places. Mark each stateful spring bean as "uniquePerTenant" as follows:

class SomeStatefulBean implements SomeStatefulBeanInterface {    public static boolean uniquePerTenant = true
}

Because of the way Spring AOP works, you have to create an interface for your spring bean and make sure you are wiring the interface, not the implementation itself.

Sometimes, you may not have access to the source code to add "public static boolean uniquePerTenant = true" to the spring bean. You can still make the bean unique by adding the name of the bean to the "tenant.uniquePerTenantBeans" property in Config.groovy:

tenant {
    uniquePerTenantBeans = ["beanName1", "beanName2"]
}
