33.1 自定义RestTemplate

当使用RestTemplateBuilder构建RestTemplate时,可以通过RestTemplateCustomizer进行更高级的定制,所有RestTemplateCustomizer beans将自动添加到自动配置的RestTemplateBuilder。此外,调用additionalCustomizers(RestTemplateCustomizer…)方法可以创建一个新的,具有其他customizers的RestTemplateBuilder

以下示例演示使用自定义器(customizer)配置所有hosts使用代理,除了192.168.0.5

static class ProxyCustomizer implements RestTemplateCustomizer {

    @Override
    public void customize(RestTemplate restTemplate) {
        HttpHost proxy = new HttpHost("proxy.example.com");
        HttpClient httpClient = HttpClientBuilder.create()
                .setRoutePlanner(new DefaultProxyRoutePlanner(proxy) {

                    @Override
                    public HttpHost determineProxy(HttpHost target,
                            HttpRequest request, HttpContext context)
                                    throws HttpException {
                        if (target.getHostName().equals("192.168.0.5")) {
                            return null;
                        }
                        return super.determineProxy(target, request, context);
                    }

                }).build();
        restTemplate.setRequestFactory(
                new HttpComponentsClientHttpRequestFactory(httpClient));
    }

}
