README.md dozer-experiments Some experiments in using dozer custom converters along with spring bean based declarations. Description This project constitutes a set of dozer based special purpose custom converters for the following use cases. The source class and target class are the mappable entities which the will invoke to get the mapping done. • A field of target class to be substituted by a type specific constant (mostly the primitives and date). Here the particular target field is simply substituted with a constant. • A field of target class to be substituted by a pre-defined bean in the spring beans xml.Here the particular target field is a complex custom type which is a bean defined with appropriate values for its attributes.

Is there a way to define a custom converter in Dozer for converting one top-level type to another, which is itself a Spring bean and thus can get its dependencies.

• A target field which is of a java collection type (for now it only List type is supported). Here the source bean needs to be converted to a target type and further added as an element into a collection of the target type. Custom converters The different converters considered here are as follows: Primitive converters: The date and other primitive types are a set of simple converters where a custom-converter-param contains a value in string form.

2012 The service layer is a where business logic is located, and the persistent layer is converted to and from the JPA entities & JAXB beans using. This example doesn't have this, but the service layer is where general handling of exceptions and validation can be put in place using AOP. Lynda - Muse Essential Training By Justin Seeley. This way standard Spring runtime exceptions can be thrown, but before they would go to the REST controller layer they could be translated into i18n friendly user messages. Also validation can intercept requests and immediately return results before any of the actual business logic starts processing in a service. 1. Spring Configuration This is the Spring Dozer Mapper configuration. More than one mapping file can be passed in or wild cards can be used to load mapper configs.

A larger application may have a need to have different dozer mappers with different rules, and they could all be defined here. Then Spring injection could be controlled with custom qualifiers. An example could be if you wanted to completely copy an existing contact, but exclude primary keys from being copied. Then this new copy could be persisted as a new record. META-INF/spring/services/mapper-context.xml classpath:/dozer/dozer-joda-mappings.xml classpath:/dozer/dozer-mappings.xml Spring configuration for loading all converters and services. META-INF/spring/services/services-context.xml Spring configuration for security. This has the authentication manager use the default JDBC user service and activates detection of the @Secured annotation on Spring beans.
