我使用以下代码片段获取用户ID。审核日志所需的
最终UserInfo userInfo = SecurityContext.getUserInfo（）; 最终字符串userId = userInfo.getLogonName（）;
在Cloud Foundry中部署应用程序后，它可以按预期工作。
问题是当您在localhost中运行应用程序时。上述方法无效，并导致异常。
要处理此问题，我还使用下面的代码段进行了模拟，
@Profile("local")
@Configuration
public class LocalSecurityConfig {
private static final Logger LOGGER = CloudLoggerFactory.getSanitizedLogger(LocalSecurityConfig.class);
public static final String XSAPPNAME = "test-xsappname!t0";
public LocalSecurityConfig() throws IOException {
final MockUtil mockUtil = new MockUtil();
mockUtil.mockDefaults();
mockUtil.mockAuditLog();
final String publicKey = FileUtils.readFile("publicKey.txt");
final Map<String, String> verificationkey = ImmutableMap.of("verificationkey", publicKey);
final JsonObject xsuaaServiceCredentials = new Gson().toJsonTree(verificationkey).getAsJsonObject();
when(((ScpCfCloudPlatform) CloudPlatformAccessor.getCloudPlatform())
.getXsuaaServiceCredentials(org.mockito.ArgumentMatchers.any(DecodedJWT.class)))
.thenReturn(xsuaaServiceCredentials);
}
---
}
上述代码对于本地集成测试非常有效。
下面的代码getUserId（）的最终代码userInfo.getLogonName（）中发生异常
@AfterQuery(entity = VIEW_CLOUDSERVICES, serviceName = LANDSCAPE_SERVICE)
public QueryResponse afterQueryTechnicalServices(QueryRequest req, QueryResponseAccessor res, ExtensionHelper h) {
List<EntityData> entData = res.getEntityDataList();
LOG.info("##### CloudServices.afterQuery: {} ########", entData.size());
QueryResponse response = null;
String userId = null;
String identityZone = null;
try {
userId = getUserId();
identityZone = SecurityContext.getUserInfo().getIdentityZone();
} catch (UserInfoException e1) {
response = QueryResponse.setError(ErrorResponse.getBuilder().setStatusCode(HttpStatus.UNAUTHORIZED.value())
.setCause(e1).setMessage("USERCONTEXT_UNAUTHORIZED", e1.toString()).response());
LOG.error("Failed to Read User Information: Exception Text={}", e1.getMessage(), e1);
AuditLogger.logDataRead(new AccessRequester(userId, identityZone, null, null),
new AuditedDataObject(ENTITY_ENDPOINT, (String) "LMS"),
new AuditedDataSubject("person", "user", userId), null,
new AccessedAttribute(VIEW_CLOUDSERVICES, Operation.READ, "Read Cloud Services", null, entData, true));
return response;
}
AuditLogger.logDataRead(new AccessRequester(userId, identityZone, null, null),
new AuditedDataObject(ENTITY_ENDPOINT, (String) "LMS"),
new AuditedDataSubject("person", "user", userId), null,
new AccessedAttribute(VIEW_CLOUDSERVICES, Operation.READ, "Read Cloud Services", null, entData, true));
return QueryResponse.setSuccess().setData(entData).response();
}
private String getUserId() throws UserInfoException {
final UserInfo userInfo = SecurityContext.getUserInfo();
System.out.println(userInfo);
final String userId = userInfo.getLogonName();
System.out.println(userId);
MDC.put("user_name", userId);
LOG.debug("UserConfig - ClientId: {}", userInfo.getClientId());
if (userId == null || userId.length() == 0) {
throw new IllegalStateException("logon_name attribute was not returned from UserInfo!");
}
System.out.println("Benu" + "returned");
return userId;
}

我调查了您报告的异常的堆栈跟踪。事实证明，只有当您的 VCAP Services 环境变量的条目缺少"name" : "..."值时，才会发生此错误。请相应地检查（并添加）值。
有关VCAP服务条目中所需/建议值的更多信息，请查看类com.sap.xs.env.Service和带注释的属性：
