spring_boot_starter_feign 0.1.7

Feign clients for spring_boot_dart: annotate an interface with @FeignClient and @GetMapping, inject it as a bean; JSON via ObjectMapper, interceptors, retries, fallbacks.

0.1.7

• @GetMapping() without a path calls the url and path of the client itself.
• required and defaultValue of @RequestParam / @RequestHeader and required of @PathVariable: defaultValue is sent for a null argument; a required null fails the call with an ArgumentError naming the parameter before anything is sent; a null that is not required leaves a query parameter or header out (a path variable becomes an empty string).
• spring.cloud.openfeign.client.config.* keys with relaxed names, like Spring Cloud OpenFeign's binding: readTimeout, loggerLevel, defaultRequestHeaders.X-Shop, read_timeout, environment variables
• Breaking: Map parameters of @RequestParam / @RequestHeader give one query parameter / header per entry (they were sent as JSON); an object as the value of a path variable, query parameter, header or cookie (a class written as a JSON object) stops the application at startup, or fails the call with an EncodeException when only the value tells.
• Breaking: mapping headers use Spring's 'Name=value' (as Spring Cloud OpenFeign reads them; server conditions like '!Name' are ignored); 'Name: value' stops the application with the reason.
• Breaking: read-timeout is the longest wait for data (for the response, then between two chunks of the body), not a limit for the whole call; default read-timeout 60 s and connect-timeout 10 s, like Feign's Request.Options() (0 for none).
• Breaking: RequestTemplate.header adds a value like Feign's (it replaced); new removeHeader. Interceptors run for every attempt of a call on a new template (a refreshed token reaches the retry); default-request-headers (and the default Accept) are applied after the interceptors, for names they did not set.
• Breaking: dismiss404 keeps throwing for void methods, like Feign.
• Breaking: the <--- ERROR and ---> RETRYING log lines are written only above logger-level: none.
• @FeignClient(contextId:, qualifiers:, primary:, dismiss404:) like Spring Cloud OpenFeign (primary and qualifiers need the matching generator).
• default-query-parameters.<name>, follow-redirects, spring.cloud.openfeign.client.decode-slash (default true: a / in a path variable stays a /).
• @CookieValue parameters (one Cookie header).
• DefaultErrorDecoder reads Retry-After as an HTTP date too.
• README: more "Differences from Spring Cloud OpenFeign" (default Accept, spaces as +, masked Authorization, logger names).

0.1.6

• update road map
• ci: release with a button on main, skip new packages when publishing; shorter pubspec descriptions

0.1.5

• Initial version: @FeignClient interfaces with request mapping annotations, JSON through ObjectMapper, interceptors, error decoding, retries, fallbacks, spring.cloud.openfeign.client.config.* properties.
• Server-sent events: methods returning EventStream<T> (or Stream<T>) read text/event-stream responses, decode each event's data, reconnect with Last-Event-ID (event-stream.* properties; not in Spring Cloud OpenFeign).
