我在IntelliJ IDEA 15.0.3中创建了一个Java Gradle项目.但是我收到以下错误.

Unindexed remote maven repositories found. Disable...
        The following repositories used in your gradle projects were not indexed yet: 
        http://repo1.maven.org/maven2
        If you want to use dependency completion for these repositories artifacts,
        Open Repositories List, select required repositories and press "Update" button (show balloon)

当我打开存储库列表并单击更新时,我收到以下错误

java.lang.RuntimeException: java.io.IOException: Transfer for nexus-maven-repository-index.properties failed

我正在尝试使用密钥库文件将 JSON 请求发送到安全的 REST web 服务，并且我正在使用 Jersey API。下面是我的代码片段

SslConfigurator sslConfigurator = SslConfigurator.newInstance().trustStoreFile("C:\\Users\\******\\test.keystore").trustStorePassword("password");
SSLContext sslContext = sslConfigurator.createSSLContext();
Client client = ClientBuilder.newBuilder().sslContext(sslContext).build();
WebTarget target = client.target("https://hostname:portnumber").path("resourse/methodname/v1");

Form form = new Form();
form.param("key1", "value1");
form.param("key2", "value2");

Response response = target.request(MediaType.APPLICATION_JSON_TYPE).post(Entity.entity(form, MediaType.APPLICATION_FORM_URLENCODED_TYPE));
System.out.println(response);

但是我在最后一行出现以下异常。

我正在使用 jHipster 创建一个类似博客的应用程序，并希望支持 2 种语言（英语和中文）的 i18n。jHipster 页面（https://jhipster.github.io/installing-new-languages/）仅解释了 UI 元素上的 i18n。但是如何为实体的值提供国际化支持呢？在本例中，我希望博客的文章实体采用两种语言。解决方法之一是将用户提供的两种语言的值放入单独的实体字段中并相应地显示。这是正确的做法吗？
