Question

我在课堂上添加了一些sun.net软件包时遇到了问题。我添加了此导入：

import sun.net.www.protocol.http.Handler;

当我运行微服务（spring-boot）时，我没有问题，但是当我尝试执行mvn clean install时，出现此错误：

[错误]无法执行目标 org.apache.maven.plugins：maven-compiler-plugin：3.8.0：compile （默认编译）项目坚持执行gg：编译失败[ERROR] /E：/Angelo/Insist/code/insist/insist-api/src/main/java/com/insist/server/service/BlizzardApiService.java：[25,28] 软件包sun.net.www.protocol.http不可见[错误]（软件包在模块java.base中声明了sun.net.www.protocol.http，不能将其导出到未命名的模块）[错误]

我读到它与一些module-info.java有关，但不确定该怎么做。我正在使用OpenJDK11 btw。

这是我课堂的一部分：

public class SomeApiService {

    private String token = null;
    private Instant tokenExpiry = null; // Instant when the token will expire


    // To allow testing of the URL/Connection
    private URLStreamHandler urlStreamHandler = new Handler();

protected String getToken() throws IOException {
        if (isTokenInvalid()) {
            String encodedCredentials = Base64.getEncoder()
                    .encodeToString(String.format("%s:%s", insistConfig.getClientID(), insistConfig.getClientSecret())
                            .getBytes(insistConfig.getEncoding()));
            // ------------------------------------------------- Allows testing/mocking of
            // the URL connection object
            URL url = new URL(insistConfig.getTokenUrl(), "", urlStreamHandler);
            HttpURLConnection con = (HttpURLConnection) url.openConnection();
            con.setRequestMethod("POST");
            con.setRequestProperty("Authorization", String.format("Basic %s", encodedCredentials));
            con.setDoOutput(true);
            con.getOutputStream().write("grant_type=client_credentials".getBytes(insistConfig.getEncoding()));

            int responseCode = con.getResponseCode();

            String response = IOUtils.toString(con.getInputStream(), insistConfig.getEncoding());

            // Reads the JSON response and converts it to TokenResponse class or throws an
            // exception
            TokenResponse tokenResponse = objectMapper.readValue(response, TokenResponse.class);

            tokenExpiry = Instant.now().plusSeconds(tokenResponse.getExpires_in());
            token = tokenResponse.getAccess_token();
        }

        return token;
    }

}

有什么办法解决此问题或如何替代sun.net.www.protocol.http.Handler？

谢谢
