[英]Transient mode for unit tests with jclouds and Openstack Swift doesn't work
I just migrated to jclouds 2.0.0 (it was suppose to some of the problems with not repeatable operations and it did). 我刚刚迁移到jclouds 2.0.0(它假设了一些不可重复操作的问题而且确实如此)。 Here are the dependencies
这是依赖项
<dependency>
<groupId>org.apache.jclouds.driver</groupId>
<artifactId>jclouds-slf4j</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>org.apache.jclouds.api</groupId>
<artifactId>openstack-keystone</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>org.apache.jclouds.api</groupId>
<artifactId>openstack-swift</artifactId>
<version>2.0.0</version>
</dependency>
I want to have unit tests for my code. 我想为我的代码进行单元测试。 But when I use
transient
as a provider: 但是当我使用
transient
作为提供者时:
SwiftApi swiftApi = ContextBuilder.newBuilder("transient")
.endpoint(endpoint)
.credentials(user, password)
.modules(modules)
.overrides(overrides)
.buildApi(SwiftApi.class);
I get this exception: 我得到这个例外:
com.google.inject.ConfigurationException: Guice configuration errors:
1) No implementation for org.jclouds.openstack.swift.v1.SwiftApi was bound.
while locating org.jclouds.openstack.swift.v1.SwiftApi

The same code run with openstack-swift
as provider (and correct credentials and endpoint) works just fine. 使用
openstack-swift
作为提供程序运行的相同代码(以及正确的凭据和端点)运行正常。 Passing any other string as newBuilder
function parameter cause: 将任何其他字符串作为
newBuilder
函数参数传递原因:
java.util.NoSuchElementException: key [wrongstring] not in the list of providers or apis: {apis=[openstack-keystone, openstack-swift, transient]}
at org.jclouds.ContextBuilder.newBuilder(ContextBuilder.java:175)
which made me think that transient
should be supported. 这让我觉得应该支持
transient
。 But how to make it work? 但是如何让它发挥作用?
You can't create a SwiftApi
view of a transient blobstore; 您无法创建瞬态blobstore的
SwiftApi
视图; instead you must use the portable BlobStore
view: 相反,您必须使用可移植的
BlobStore
视图:
String provider = ...; // openstack-swift or transient
BlobStoreContext context = ContextBuilder.newBuilder(provider)
.endpoint(endpoint)
.credentials(user, password)
.buildApi(BlobStoreContext.class);
BlobStore blobStore = context.getBlobStore();
// interact with blobStore, e.g., get, put
...
context.close();
