I had this Java code:

@Bean
    @ConditionalOnProperty( prefix = "proxy", name = "enabled", havingValue = "true")
    public RestTemplateCustomizer restTemplateCustomizer() {
        return restTemplate -> {
            var proxy = new HttpHost(host, port, scheme);
            var httpClient = HttpClientBuilder.create().setRoutePlanner(new DefaultProxyRoutePlanner(proxy)).build();
            restTemplate.setRequestFactory( new HttpComponentsClientHttpRequestFactory(httpClient));
        };
    }

where RestTemplateCustomizer is a functional interface.

But I have trouble writing this in Kotlin

[Shawn]

what does the RestTemplateCustomizer definition look like?

[davidkarlsen]

ah got it to work

[davidkarlsen]

@Bean
    @ConditionalOnProperty(prefix = "proxy", name = arrayOf("enabled"), havingValue = "true")
    fun restTemplateCustomizer(): RestTemplateCustomizer {
        return RestTemplateCustomizer { restTemplate ->
            val proxy = HttpHost(host!!, port, scheme)
            val httpClient = HttpClientBuilder.create().setRoutePlanner(DefaultProxyRoutePlanner(proxy)).build()
            restTemplate.setRequestFactory(HttpComponentsClientHttpRequestFactory(httpClient))
        }
    }

Or you could do this:

fun restTemplateCustomizer(): RestTemplateCustomizer = RestTemplateCustomizer { restTemplate ->
	val proxy = HttpHost(host, port, scheme)
	val httpClient = HttpClientBuilder.create().setRoutePlanner(DefaultProxyRoutePlanner(proxy)).build()
	restTemplate.setRequestFactory(HttpComponentsClientHttpRequestFactory(httpClient))
}

or even

fun restTemplateCustomizer() = RestTemplateCustomizer { restTemplate ->
	val proxy = HttpHost(host, port, scheme)
	val httpClient = HttpClientBuilder.create().setRoutePlanner(DefaultProxyRoutePlanner(proxy)).build()
	restTemplate.setRequestFactory(HttpComponentsClientHttpRequestFactory(httpClient))
}
