Update spring

Please, see the "Suffix Match" section of the reference documentation. If you were previously relying on the response not being written to, note that this was not an intended behavior and that we can't guarantee error handling for this case. See gh for an example of that. A java. Principal argument is no longer resolved eagerly, if it is annotated in some way such as AuthenticationPrincipal , thus allowing a custom resolver to resolve it first, before using default resolution resolution via HttpServletRequest getUserPrincipal.

This can cause issues for existing applications that are trying to inject the Spring Security Authentication but also have it annotated with AuthenticationPrincipal which now results in the injection of Authentication getPrincipal as per the intent for the annotation.

Removing AuthenticationPrincipal results in the injection of the top level Authentication object which is also a Principal and would be resolved via HttpServletRequest getUserPrincipal after the change.

Previously each part was converted to T , see gh It should not interfere with any declared by the application due to a lower priority but if you have one, you can remove it. CodecExceptions are not wrapped and still propagated.

A UriComponentsBuilder argument injected into an Controller method is now application relative i. The Spring TestContext Framework now provides first-class support for inheriting and overriding test-related annotations from enclosing classes. This improves the programming model for using JUnit Jupiter Nested test classes with Spring's testing support. Note, however, that annotations from enclosing classes will now be inherited by default.

This is a change in behavior that may cause some of your Nested test classes to fail after upgrading to Spring Framework 5.

To revert to the behavior present in Spring Framework 5. Consult the Javadoc for NestedTestConfiguration and the reference manual for details. There maybe be some other slight variations due to the improved Kotlin DSL, see this commit for more details.

In Reactor Core 3. You may have to add io. Spring's annotation retrieval algorithms have been completely revised for efficiency and consistency, as well as for potential optimizations through annotation presence hints e. This may have side effects -- for example, finding annotations in places where they haven't been found before or not finding annotations anymore where they have previously been found accidentally. While we don't expect common Spring applications to be affected, annotation declaration accidents in application code may get uncovered when you upgrade to 5.

For example, all annotations must now be annotated with Retention RetentionPolicy. See gh , gh , and gh In the absence of declared patterns previously the path was not checked thereby matching to any path. Since the related Chrome bug is now fixed since September , Spring Framework 5. As a consequence, integration tests relying on the default JSON content type may have to be updated. See gh for more details. When upgrading to Spring Framework 5.

Config options for suffix pattern matching in RequestMappingHandlerMapping have been deprecated, and likewise config options to resolve acceptable media types from the extension of a request path in ContentNegotiationManagerFactoryBean have also been deprecated. This is aligned with defaults in Spring Boot auto configuration and Spring WebFlux does not offer such options.

See gh and related issues for details and further plans towards 5. We believe this delay will allow us to begin on time and resume fully in person activity at the end of the month.

We value your continued support as we continue to make difficult decisions in a changing environment. May you all have a safe and happy New Year. In recent weeks, we have seen a significant increase in positive COVID cases on campus, in the region and nationally.

New information is coming in daily about the omicron variant and the effectiveness of various mitigation measures. As always, our highest priority continues to be the health, safety and well-being of our campus community. Please read the following information carefully.

Classes will be held online for the first two weeks of the spring semester. Students who are able to do so should remain at home and not return to campus until in-person instruction resumes. All Danforth Campus students will complete pre-arrival and entry self-testing. All students, faculty and staff are strongly encouraged to receive a COVID booster shot if they are eligible to receive one.

We are making these scientifically-grounded decisions based on guidance from our medical experts and with your health, safety and well-being in mind.

We know there will be questions and we will communicate with you directly as new information is available. Thank you, as always, for your patience and perseverance as we continue to navigate the many twists and turns of the pandemic.

Washington University in St. As was true in the Fall Semester, fully vaccinated individuals will not be subject to mandatory weekly surveillance testing. However, any member of the Notre Dame community who is asked to present for surveillance testing must report as requested. Those who are not fully vaccinated are required to report for weekly surveillance testing as outlined here for faculty and staff, and here for students.

Symptomatic testing is available at the University Testing Center by appointment for students, faculty, and staff. To make an appointment, students should contact UHS at , and faculty and staff should contact the Notre Dame Wellness Center at , or seek care from their primary care provider.

For testing sites and appointments available outside of the University, please click here. Given the recent updated guidance from the CDC and in consultation with public health officials, the University has modified its isolation and quarantine protocols as follows:. Until 90 percent of our community achieves full vaccination with a booster and we are able to eliminate the indoor masking requirement, University-sponsored gatherings on or off campus may not include food or drink, and masks must be worn at all times.

Venues must also be appropriately sized for the gathering. To learn more, please visit here. Thank you for your continued patience, resilience and fortitude. As we welcome the new year, know that you and your loved ones are in our prayers.

Sincerely, Rev. John I. Jenkins, C.
