IPF 3.1 Migration Guide
IPF 3.1 comes with some backward-incompatible changes, mostly due to reducing mandatory dependencies to the Spring framework and some internal refactorings in the IHE-related classes.
Spring dependencies
IPF 3.1 encapsulates most Spring dependencies in the new ipf-commons-spring module. When you use IPF with Spring, the required Maven dependency is:
<dependency> <groupId>org.openehealth.ipf.commons</groupId> <artifactId>ipf-commons-spring</artifactId> <version>${ipf.version}</version> </dependency>
The only other modules that directly depend on Spring are ipf-commons-flow and ipf-platform-camel-flow. All other modules do not depend on Spring anymore. If you so far benefitted from transitive Spring dependencies, you may need to add these dependencies in your modules.
Mapping Service
org.openehealth.ipf.commons.map.BidiMappingService cannot be configured with Spring’s Resource objects anymore. With Spring, use org.openehealth.ipf.commons.spring.map.SpringBidiMappingService
instead and call the new setMappingResource or setMappingResources methods. The new class is located in the ipf-commons-spring module. See Mapping Service for details.
MLLP custom interceptors
The MLLP-based IHE endpoints offer the possibility to add custom interceptors. The interceptors parameter has been removed due to its dependency on the Spring framework. as of IPF 3.1, use the interceptorFactories parameter instead. See Custom Interceptors for details.
Logging Interceptors
The interceptors logging the payload of IHE MLLP or Web Service transactions use the Spring Expression language for determining the target file name they write into. The dependency to this library has been made optional. See MLLP Payload Logging and WS Payload Logging for details.
XDS
org.openehealth.ipf.commons.ihe.xds.core.metadata.Document offered type conversion by directly depending on Spring’s ConversionService. The new interface org.openehealth.ipf.commons.core.config.TypeConverter lets you now choose the type converter implementation. The only implementation provided by IPF is org.openehealth.ipf.commons.spring.core.config.SpringTypeConverter, located in the new ipf-commons-spring module, which realizes the previous behavior.
ATNA Auditing and IHE components
All IHE components (MLLP-based, SOAP-based, FHIR-based) have been refactored to use a common source of ATNA auditing strategies, which all now all located in the ipf-commons-ihe-XXX modules. During this refactoring, most classes have been touched, mostly changing their type parameters and moving back and forth the one or other method. This change will not be visible for ‘normal’ users of the IHE components provided by IPF. If you, however, created your own components, endpoints, audit strategies, etc. based on the respective abstract IPF classes, you will need to reproduce these refactorings in your own code. Please inspect the standard IHE transaction classes in IPF for what needs to be changed.
