Hello! :)

I have multiple (60+) microservices.
Each has a specific spring.application.name in the application.properties file.
They all use spring.config.import to get their config from spring cloud server.
On the config server, logging.file.name=${spring.application.name}.
They all depend on a shared library that includes @Configuration beans.

I want the to replace dash (-) with underscore (_) in the log filenames.

The tricky part is that the log filename is determined very early in the application lifecycle, before I can introduce new properties programmatically via @Configuration.

I do not want to introduce a separate property in each microservice.
I do not want to introduce element in each microservice code.
I do not want to use logback-spring.xml.
I want to solve this globally, either in the shared library (via @Configuration), or in the spring cloud server.

Please help me! :)

@mplain

Also, I want to use git.branch as a label to get the correct config from the server.
I have git.properties generated by the plugin (declared in the parent pom in the shared library).
How can I set spring.cloud.config.label to 'git.branch', considering that 'git.properties' is not scanned by default?
Again, I want to solve this globally for all microservices using the shared library (parent pom or @Configuration).
I do not want to introduce new elements in each application.

Hi All, I know this technically isn't the place but the Spring GCP Gitter seems dead:

I'm trying to use GCP Pub sub with spring boot and I want to publish a simple JSON message to a NodeJS API. I found this sample here: https://github.com/spring-cloud/spring-cloud-gcp/tree/main/spring-cloud-gcp-samples/spring-cloud-gcp-integration-pubsub-json-sample but when I try to add

  @Bean
    public JacksonPubSubMessageConverter jacksonPubSubMessageConverter(ObjectMapper objectMapper) {
        return new JacksonPubSubMessageConverter(objectMapper);
    }

to my project and the dependancy

    implementation group: 'org.springframework.cloud', name: 'spring-cloud-gcp-starter-logging'
    implementation group: 'org.springframework.cloud', name: 'spring-cloud-gcp-starter-logging', version: '1.2.8.RELEASE'
    implementation platform('com.google.cloud:libraries-bom:22.0.0')
    implementation 'com.google.cloud:google-cloud-pubsub:1.114.2'
    implementation group: 'org.springframework.cloud', name: 'spring-cloud-gcp-starter-pubsub'
    implementation group: 'org.springframework.cloud', name: 'spring-cloud-gcp', version: '1.2.8.RELEASE', ext: 'pom'

I get the following error: Cannot resolve symbol 'JacksonPubSubMessageConverter'

Can someone point me in the right direction? Do I need to use Spring integration?

Hey all, I'm looking through the documentation for testing Spring Security with WebFlux (https://docs.spring.io/spring-security/site/docs/current/reference/html5/#webflux-testing-jwt) and it shows a static method being used mockJwt() and jwt() but it doesn't have any references to what class that comes from. Can anyone let me know which classes those methods are located in? I asked on the spring-security gitter but seems that theres not a lot of traffic on that channel vs this one. I also feel the documentation probably should be updated and potentially do a PR when it's known unless someone else wants to take care of it.

I'm having trouble using spring.config.import: vault:// with different profiles. For my local profile, I'm using a different vault host which does not need a custom ssl-trust-store. When I move spring.config.import:vault:// from the application.yml to application-local.yml my application runs correctly. I'm not sure where I should create a bug ticket for this. spring-boot or spring-cloud-vault?

Hey everyone, I hope we are all having a wonderful day! 💚. I'm new to spring but also to jackson so I need some help with a special case.

I am trying to improve developer experience and also reduce boilerplate and so I want to be able to automatically serialize (with jackson) a custom type that is supposed to represent a i18n translation key eg StringResource to be used as a property like

class CallToActionDto(val text: StringResource, val deepLink: String)

I am using springs kotlin coroutine support so I have a suspend handler method like

suspend fun getCallToAction(@RequestParam lang: "en" | "de" | "fr" etc): CallToActionDto { ... }

As you can see the client language is passed as a query parameter.

My questions:

How do I define the serializer for this my custom type (or a factory of it)? Either the serializer needs to be scoped per request and injected with the current lang query param / resolved Locale OR the serializer would be global but per serialize operation will somehow have access to the request scope to be able to determing the lang / Locale.
Will this work out of the box with suspend handler functions? For instance, if I wire a custom LocaleResolver that can read my query param, it will set the Locale to a threadLocal. I don't know if thread local works perfectly with suspend functions

Does anybody know a way to replace a field-injected bean of a @Component during initialization? This Spring Cloud Autoconfiguration (https://github.com/spring-cloud/spring-cloud-dataflow/blob/main/spring-cloud-dataflow-rest-client/src/main/java/org/springframework/cloud/dataflow/rest/client/config/DataFlowClientAutoConfiguration.java) has all its dependencies injected as fields, so I have no way to put a custom resttemplate there without making it my app's primary one. And I would like to avoid replicating the whole class because of this. The main exposed bean has a lot of config and it mutates quite often so it would not be maintainable

I am thinking of some BeanFactoryPostProcessor/BeanPostProcessor,/AutowiredAnnotationBeanPostProcessor trick so I can keep using the autoconfiguration and just replace its restTemplate collaborator in the least intrusive way, but it's frankly very scarcely and esoterically documented

Hi All,

I have a question around multi-Tenant. I have two Tenants in Auth0 so two different issuer URI's. I've seen from Spring security I can easily add more than one iss url by doing the following in my security config class:

@Override
    protected void configure(HttpSecurity http) throws Exception {
        JwtIssuerAuthenticationManagerResolver authenticationManagerResolver = new JwtIssuerAuthenticationManagerResolver
                ("https://xxxxxx-dev.eu.auth0.com/", "https://xxxxxx2-dev.eu.auths0.com/");

However I have a method which validates the aud in the token by doing the following:

 @Bean
    @Primary
    JwtDecoder jwtDecoder() {
        /*
        By default, Spring Security does not validate the "aud" claim of the token, to ensure that this token is
        indeed intended for our app. Adding our own validator is easy to do:
        */

        NimbusJwtDecoder jwtDecoder = (NimbusJwtDecoder)
                JwtDecoders.fromOidcIssuerLocation(issuer);

        OAuth2TokenValidator<Jwt> audienceValidator = new AudienceValidator(audience);
        OAuth2TokenValidator<Jwt> withIssuer = JwtValidators.createDefaultWithIssuer(issuer);
        OAuth2TokenValidator<Jwt> withAudience = new DelegatingOAuth2TokenValidator<>(withIssuer, audienceValidator);

        jwtDecoder.setJwtValidator(withAudience);

        return jwtDecoder;
    }

How can I have this work with BOTH issuer URI's....any help would be very much welcome as I'm going crazy here trying to figure this out :D

Thanks

Spring Application Is A Micro-Service? A confusion

One of my friend creates separate spring boot application for each functions or modules and run as a separate application and calling it as micro-service

I told him is that the microservice? There is a confusion how to treat a application or a service as micro-service

When i searched internet, i observed authentication would be in a separate service...All microservice will run independently

Can some experts give a good back around of micro-service or characteristics of micro-service to clarify the confusions
