我正在使用Jersey构建Java REST API。 Tomcat是我的Web服务器。对于用户帐户和OAuth2密钥管理，我使用的是Stormpath的Java SDK。我有一个样本用户已经通过网站创建的，我每次张贴该帐户，以我的应用程序在邮差v1/token端点的JSON的用户名/密码请求的时候，我得到这个异常和堆栈跟踪：为什么在尝试从Stormpath获取OAuth2密钥时收到com.stormpath.sdk.lang.InstantiationException？

我的JSON：
{
"login": "**EMAIL**",
"password": "**PASSWORD**"
}
exception的文档中没有任何内容。这是我的终端/服务。 （我开始抓所有的异常，这样我可以看看发生了什么事也，AuthRequest是在登录名和密码字段不空约束一个简单的bean）：
package com.ficcy.api.services;
//truncated imports
@Path("/token")
public class AuthService {
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public AccessToken getToken(AuthRequest ar) {
AccessToken rtn = null;
try {
PasswordGrantRequest pgr = Oauth2Requests.PASSWORD_GRANT_REQUEST.builder().setLogin(ar.getLogin())
.setPassword(ar.getPassword()).build();
OauthGrantAuthenticationResult authResult = Authenticators.PASSWORD_GRANT_AUTHENTICATOR
.forApplication(Config.getApplication()).authenticate(pgr);
rtn = authResult.getAccessToken();
} catch (Exception e) {
System.err.println(e.getMessage());
e.printStackTrace();
}
return rtn;
}
}
编辑：这是我的配置类，在那里我存储我的Stormpath应用：
package com.ficcy.api.config;
//truncated imports
public class Config {
private static Client client = Clients.builder().build();
private static Application application;
static {
Tenant tenant = client.getCurrentTenant();
ApplicationList applications = tenant
.getApplications(Applications.where(Applications.name().eqIgnoreCase("ficcy-api")));
application = applications.iterator().next();
}
public static Client getClient() {
return client;
}
public static Application getApplication() {
return application;
}
public static Hashids getHashid(String salt) {
return new Hashids(salt, 6);
}
}

您使用Java SDK版本“1.0.RC8.3”吗？你的代码中的哪一行会得到异常？在执行您在'AuthService＃getToken（AuthRequest）' – mario
中显示的代码时，我无法重现您的错误。我正在使用Java 8'1.0.66'。几分钟前，我改变了我的build.gradle使用'1.0.RC8.2'和'1.0.RC8.3'来为所有Stormpath库提供响应，并且一切正常。我刚回到'1.0.RC8.3'，它又失败了。编辑：该错误是33行 – psamp
