Summary
McpSseShutdownConfigurationand its test —WebMvcSseServerTransportProvideris@Deprecated(forRemoval=true)in Spring AI 2.0; the graceful-shutdown workaround it provided becomes a compilation time-bomb on the next Spring AI releaseprotocol=SSE+HttpClientSseClientTransporttoprotocol=STREAMABLE+HttpClientStreamableHttpTransport, aligning tests with the Spring AI 2.0 defaultintegrations/page.adoc: document Streamable HTTP as the default (endpoint/mcp), remove the now-unnecessary mcp proxy workaround, and add a deprecation callout for SSE users explaining the shutdown behaviour and migration pathImpact on SSE clients
SSE transport (
protocol: SSE) continues to work during normal operation. The only regression is on server shutdown: withoutMcpSseShutdownConfiguration, Tomcat waits up to 30 s before force-closing open SSE streams rather than draining them gracefully.This is the pre-workaround behaviour and is documented in the updated reference page. Users still on SSE should migrate to
protocol: STREAMABLE.Closes: #2047
