- Many of the non-recommended classes and methods are removed in the code base
Core Features
Enhancements to JDK8:
- Provides getfile or isfile defensive abstraction when accessing resuouce
- Effective method parameter access based on Java 8 reflection enhancement
- Added support for declaring the default method in the spring core interface consistent use of JDK7 charset and Standardcharsets enhancements

- Auto Detect log4j 2.x, SLF4J, JUL (java.util.Logging) instead of other support
- Provides getfile or isfile defensive abstraction when accessing resuouce
- NIO-based Readablechannel also offers this new feature
Core container
- Supports candidate component indexes (also supports environment variable scanning)
- Support @nullable Annotations
- Functional Style Genericapplicationcontext/annotationconfigapplicationcontext
- Basic Support Bean API registration
- Provides things, caches, asynchronous annotation detection when using cglib dynamic proxies at the interface level
- XML Configuration Scope streaming
- Spring WEBMVC
- Full Servlet 3.1 Signature support in spring-provied filter implementation
- Support for Servlet4.0 pushbuilder parameters in the Spring MVC controller method
- Data binding for multiple immutable objects (kotlin/lombok/@ConstructorPorties)
- Support jackson2.9
- Support for JSON binding API
- Support PROTOBUF3
- Supports Reactor3.1 flux and mono
Springwebflux
- The new Spring-webflux module, a reactive-based SPRING-WEBMVC, is fully asynchronous, non-blocking, designed to use the Enent-loop execution model and the traditional thread pool model.
- Reactive description in Spring-core such as encoding and decoding
- Spring-core related infrastructure, such as encode and decoder, can be used to encode and decode data streams; DataBuffer can use Java bytebuffer or Netty bytebuf; Reactiveadapterregistry can provide transport layer support for related libraries.
- Included in the Spring-web package are Httpmessagereade and httpmessagewrite.
Improvements in testing
- Completed on the JUnit 5 ' s Juptier Programming and expansion module in the Spring TestContext framework
- Springextension: An implementation of JUnit's many extensible APIs that provides support for the existing Spring TestContext framework, using @extendwith (Springextension.class) the annotation reference.
- @SpringJunitConfig: A composite annotation
- @ExtendWith (Springextension.class) from JUnit Jupit
- @ContextConfiguration from srping TestContext frame
- @DisabledIf If you provide an expression or placeholder for the property value True, signal: The test class or test method of the annotation is disabled
- Support for parallel testing in the Spring TestContext framework
- The detailed view of the test section is supported by Springrunner in the Sring TestContext framework to support TESTNG, JUNIT5, new execution before and after test callbacks.
- The Testexecutionlistener API and Testcontextmanager new Beforetestexecution () and Aftertestexecution () callbacks. Mockhttpservletrequest added the Getcontentasbytearray () and getcontentasstring () methods to access the request body
- If the character encoding is set as a mock request, the Redirectedurl () and Forwardedurl () methods of the spring MVC test can be printed in the print () and log () methods to support the variable expression URL template.
- The Xmlunit has been upgraded to version 2.3.
