How to produce metrics of URI correctly in spring boot 2 + webflux I have a problem using spring boot 2.0.3 + spring webflux (functional endpoints) + metrics. According to the official doc: The generated metrics of uri should be the request’s URI template prior to variable substitution Which means instead of /api/person/123, the generated metrics of URI should be something like /api/person/{id}. However, when I query those metrics on my spring boot app with this link http://localhost:8080/actuator/metrics/http.server.requests, I got these URIs: /api/person/2 /api/person/33 /api/person/12 To reproduce this issue, I put a sample code here: https://gitlab.com/itsleon/demo Can someone please shed some light on this issue? Thanks in advance! 1 Answer 1 There's an open issue for that in Spring Boot. Currently, Spring WebFlux fn doesn't provide the information about the URI pattern that matched fo...

Spring Boot Embedded Tomcat Performance I am developing Microservices API for my application. I started with Spring Boot application. I created two artifacts - "business code with embedded tomcat" and "business code without embedded tomcat" . When I compare the performance results, I can see that the "non-embedded tomcat" (i.e. executing on standalone tomcat) gives good output because of native execution. So basically what is the difference between the embedded tomcat and the standalone tomcat regarding implementation? How the performance varies between two executions? How you did the tests? Could you explain? Thanks. – Rudge Oct 30 '16 at 18:46 @Rudge: Using Jmeter i simulated load on both scenarios. I am using camel in my business-code. At the end of transaction, i am printin...

Spring boot 2.0 custom converter being ignored I've either completely miss-understood converters, or all the examples/blogs/docs I've found are assuming I've done a step... My understanding is that when I post a String , the converter will pick it up and give the Controller a POJO instead. String Controller The problem I have is the converter is never being called. The payload coming into the controller is a standard JSON API string { "data":{ "attributes":{ "created-date":null, }, "type":"steaks" } } The converter: @Slf4j @Configuration public class SteakConverter implements Converter<String, Steak> { @Override public Steak convert(String value) { log.info("converter value {}", value); return new Steak.builder().build(); } } The controller: @Slf4j @CrossOrigin @RestController public class SteakController { @PostMapping("/steaks") ...

IgnoreCase Finder Not Working with Spring Data Rest and Neo4J I am unable to coax Spring Data Neo4J (with Spring Data Rest) to ignore case with a finder method. Here's an example repository: @RepositoryRestResource public interface WidgetRepository extends PagingAndSortingRepository<Widget, Long> { Optional<Widget> findByNameIgnoreCase(String name); } This example will only find widgets by exact case even though I have the IgnoreCase keyword. I would appreciate advice on how to get a finder method to ignore case with Neo4J. Thanks! IgnoreCase 1 Answer 1 The case specific keywords are not implemented in Spring Data Neo4j yet. But it is possible to use regex in a derived query method. Define a regex finder method Optional<Widget> findByNameMatchesRegex(String name); Optional<Widget> findByNameMatchesRegex(String name); and use it like this widgetRepository.findByNameMa...

Using Pebble template engine with Spring Boot So I'm trying to integrate Pebble templating engine to my spring boot application but I'm confused on how to implement this. So I've read through their site on how to implement it however it says for Spring MVC which I think not similar with Spring Boot. I also go to their github page then trying to add their maven dependency to POM.xml but I don't know if I will configure something or it is the same as Thymeleaf or Mustache that are autoconfigured. Link to their site: http://mitchellbosecke.com/pebble/ They provide an example on their github that you can try, to get an idea of how it works: github.com/PebbleTemplates/pebble-example-spring – Dovmo May 14 at 3:17 1 Answer 1 Add the starter depe...
