标签： java guice jclouds druid

我正在研究使用jclouds作为Rackspace Cloud Files的druid扩展程序，我遇到了Google guice的问题，而且我对Java不太自信。

我已经看过this question，但似乎guice版本中没有冲突。

这是正在执行的代码：

@Provides
@LazySingleton
public CloudFilesApi getCloudFilesApi(final CloudFilesAccountConfig config) {
    log.info("Provider: " + config.getProvider());
    log.info("Username: " + config.getUserName());
    log.info("Api key: " + config.getApiKey());
    ContextBuilder cb = ContextBuilder.newBuilder(config.getProvider());
    log.info("Context builder built.");
    cb = cb.credentials(config.getUserName(), config.getApiKey());
    log.info("Context builder authenticated.");
    CloudFilesApi cfa = cb.buildApi(CloudFilesApi.class);
    log.info("Cloud Files Api built.");
    return cfa;
}

这是日志：

我也不明白为什么没有打印字符串"Cloud Files Api built."。

classpath 是lib目录：

user@host:/opt/druid# ls lib | grep guice
guice-4.0-beta.jar
guice-assistedinject-3.0.jar
guice-multibindings-4.0-beta.jar
guice-servlet-4.0-beta.jar
jersey-guice-1.17.1.jar

更新1

也许与this issue有关？我要尝试降级到Google guice 3.0。

更新2

我将Google guice降级为3.0，现在我已经：

user@host:/opt/druid# ls lib | grep guice
guice-3.0.jar
guice-assistedinject-3.0.jar
guice-multibindings-3.0.jar
guice-servlet-3.0.jar
jersey-guice-1.17.1.jar

现在错误发生了变化：

查看你的类路径：

static class ToSort {
    Integer val;

    public ToSort(Integer val) {
        this.val = val;
    }

    @Override
    public String toString() {
        return "ToSort{" +
                "val=" + val +
                '}';
    }
}

public static void main(String[] args) {
    Observable.just(new ToSort(1), new ToSort(2), new ToSort(3))
            .toSortedList((o1, o2) -> (-1) * o1.val.compareTo(o2.val))
            .subscribe(list -> System.out.print(Arrays.toString(list.toArray())));
}

您正在使用Guice v4.0b但是使用了AssistedInject Guice扩展程序的v3.0。您应该从版本到版本一次升级它们。听起来你把所有东西都放回到v3.0，这有效，但你可以改为升级AssistedInject扩展。
