在 weblogic 12c 上部署时创建 Azure 存储容器失败

Question

我有一个非常简单的 spring boot 项目用于测试，它在独立运行时成功地在现有 Azure 存储帐户中创建了一个容器。但是，当部署在 WebLogic 12c 服务器中时，它会失败并出现我在 Internet 上找不到的错误。

该项目有一个控制器、一个应用程序、一个 weblogic.xml 和 pom.xml，仅此而已。在本地运行时完美运行，使用帐户的连接字符串（使用帐户密钥）和容器的名称创建一个容器。

这是Controller类的代码：

package com.example;

import java.io.IOException;
import java.net.URISyntaxException;
import java.security.InvalidKeyException;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.microsoft.azure.storage.CloudStorageAccount;
import com.microsoft.azure.storage.StorageException;
import com.microsoft.azure.storage.blob.CloudBlobClient;
import com.microsoft.azure.storage.blob.CloudBlobContainer;

@RestController
public class DemoController {

    @RequestMapping(value = "/createAzureContainer", method = RequestMethod.GET)
    void createAzureContainer() 
            throws URISyntaxException, StorageException, IOException, InvalidKeyException {

        CloudStorageAccount storageAccount = 
                CloudStorageAccount.parse("DefaultEndpointsProtocol=https;" + 
                        "AccountName=[accountName];AccountKey=[accountKey]");
        CloudBlobClient blobClient = storageAccount.createCloudBlobClient();
        CloudBlobContainer container = blobClient.getContainerReference("[containerName]");
        container.createIfNotExists();
        container.downloadAttributes();
    }
}

以及Application类的代码：

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.WebApplicationInitializer;

@ComponentScan
@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer 
        implements WebApplicationInitializer {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(DemoApplication.class);
    }
}

这是weblogic.xml，位于src/main/webapp/WEB-INF:

<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.4/weblogic-web-app.xsd">

        </wls:prefer-application-packages>
    </wls:container-descriptor>
</wls:weblogic-web-app>

最后是 pom.xml：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

有了这个，任何拥有 Azure 存储帐户的人都可以尝试独立运行并创建容器。但是在部署到 WebLogic 12c 时，以下行：

        container.createIfNotExists();

失败并出现以下异常，这听起来像是您在上传 blob 时可能遇到的问题，但在互联网上搜索容器时找不到任何关于它的参考：

非常感谢您的帮助，感谢您的宝贵时间。

Answer 1

根据您的错误信息和 Azure Storage 官方error codes，该问题是由于缺少Content-Length 标头引起的，请参见下文。

您可以尝试使用 Fiddler 检查错误代码411 & response 以确定异常发生时的问题原因。

根据我的例外情况，我认为 WebLogic 服务器导致缺少 Content-Length 标头问题。我搜索并发现 WebLogic 服务器使用了一些向后兼容的策略来使用自己的实现来实现某些标准，例如 JAX-RS、JAX-PRC 等。

所以我觉得你可以参考Oracle官方文档Invoking Web Services from Client Applications and WebLogic Server&Fusion Middleware Developing and Securing RESTful Web Services for Oracle WebLogic Server 12.1.3来解决问题。

我认为一些解决方案可能有助于解决它。

1. 根据文档1，尝试添加如下代码。

   // Setup the global JAX-RPC service factory
   System.setProperty( "javax.xml.rpc.ServiceFactory", "weblogic.webservice.core.rpc.ServiceFactoryImpl");
   

2. 尝试Configuring the Web Application to Use Jersey 2.5.1 (JAX-RS 2.0 RI)。

3. 尝试参考Developing RESTful Web Service Clients 更改或设置您的代码。

希望对你有帮助。
