带有javaee-api 8.0的DocuSign REST API Java sdk抛出java.lang.ClassNotFoundException：org.glassfish.jersey.internal.RuntimeDelegateImpl

问题描述

我正在使用Java sdk for REST api与docusign进行API集成。这是docusign sdk依赖项。

compile group: 'com.docusign',name: 'docusign-esign-java',version: '3.6.0'

我的应用程序正在运行Java ee 8.0容器，因此在我的单元测试中，我具有依赖性。

providedCompile group: 'javax',name: 'javaee-api',version: '8.0'

这是我简单的测试程序。

import java.util.ArrayList;
import java.util.List;

import com.docusign.esign.client.apiclient;
import com.docusign.esign.client.auth.OAuth;

public class DocuSignTest {
    
    public static void main(String[] args) throws Exception {
        
        System.out.println("\nFetching an access token via JWT grant...");

        List<String> scopes = new ArrayList<String>();
        // Only signature scope is needed. Impersonation scope is implied.
        scopes.add(OAuth.Scope_SIGNATURE);
        String privateKey = "loaded-from-properties";
        byte[] privateKeyBytes = privateKey.getBytes();
        
        apiclient apiclient = new apiclient();
        
        apiclient.setoAuthBasePath("https://demo.docusign.net");
        OAuth.OAuthToken oAuthToken = apiclient.requestJWTUserToken (
                "0dd50ffa-6561-4321-xxxx-39d2738d9e8f","0dd50ffa-6561-1234-yyyy-39d2738d9e8f",scopes,privateKeyBytes,120);
        
        System.out.println("Done");
    }
}

在初始化apiclient时抛出以下异常

请注意，如果我删除javaee-api依赖项，则可以正常运行。看起来docusign sdks需要jax-rs 1.1（jersey 1.19.1）类，但它与javaee-api 8.0 jar中的jax-rs 2.1类（在javax.ws.rs包中）冲突。我无法删除此依赖关系，因为代码在javaee 8.0容器下运行，并且此依赖关系由运行时容器提供。

我认为，在javaee 8.0容器内将docusign java sdk用于rest api是非常正常的用例，应该有一种解决方法。

解决方法

您能看到DocuSign example set for Java是否在您的开发环境中工作吗？

然后从那里我们可以看到您的应用程序与众不同。谢谢。
