Question

我正在尝试将一个实体添加到Azure的表中，但是我遇到了很多错误。这是我的代码：

package table;
import com.microsoft.azure.storage.*;
import com.microsoft.azure.storage.table.*;
import com.microsoft.azure.storage.table.TableQuery.*;

public class tableTutorial {

 public static final String storageConnectionString=
"DefaultEndpointsProtocol=https;"+
"AccountName=my_storage_name;"+
"AccountKey=my_storage_account_key;"+
"EndpointSuffix=core.windows.net";

public static void main (String args[]) {
try
    {
        // Retrieve storage account from connection-string.
        CloudStorageAccount storageAccount =
            CloudStorageAccount.parse(storageConnectionString);

        // Create the table client.
        CloudTableClient tableClient = 
 storageAccount.createCloudTableClient();

        // Create a cloud table object for the table.
        CloudTable cloudTable = tableClient.getTableReference("people");

        // Create a new customer entity.
        CustomerEntity customer1 = new CustomerEntity("Harp", "Walter");
        customer1.setEmail("Walter@contoso.com");
        customer1.setPhoneNumber("425-555-0101");

        // Create an operation to add the new customer to the people table.
        TableOperation insertCustomer1 = 
      TableOperation.insertOrReplace(customer1);

        // Submit the operation to the table service.
        cloudTable.execute(insertCustomer1);
        }
        catch (Exception e)
        {
        // Output the stack trace.
        e.printStackTrace();
       }

    }

}



class CustomerEntity extends TableServiceEntity {
public CustomerEntity(String lastName, String firstName) {
    this.partitionKey = lastName;
    this.rowKey = firstName;
   }

 public CustomerEntity() { 

   String email;
   String phoneNumber;
 }
 public String getEmail() {
    return this.email;
  }

 public void setEmail(String email) {
    this.email = email;
  }

  public String getPhoneNumber() {
    return this.phoneNumber;
  }

  public void setPhoneNumber(String phoneNumber) {
    this.phoneNumber = phoneNumber;
  }
}

我得到的错误是：

com.microsoft.azure.storage.StorageException：尝试在序列化期间访问实体的无法访问的成员。在com.microsoft.azure.storage.table.TableServiceEntity.writeEntity（TableServiceEntity.java:468）在com.microsoft.azure.storage.table.TableEntitySerializer.getPropertiesFromDictionary（TableEntitySerializer.java:213）在com.microsoft.azure.storage.table.TableEntitySerializer.writeJsonEntity（TableEntitySerializer.java:129）在com.microsoft.azure.storage.table.TableEntitySerializer.writeSingleEntityToStream（TableEntitySerializer.java:63）在com.microsoft.azure.storage.table.TableOperation.insertImpl（TableOperation.java:381）在com.microsoft.azure.storage.table.TableOperation.performInsert（TableOperation.java:362）在com.microsoft.azure.storage.table.TableOperation.execute（TableOperation.java:682）在com.microsoft.azure.storage.table.CloudTable.execute（CloudTable.java:529）在com.microsoft.azure.storage.table.CloudTable.execute（CloudTable.java:496） at table.tableTutorial.main（tableTutorial.java:86）引起：java.lang.IllegalAccessException：类com.microsoft.azure.storage.table.PropertyPair无法访问类table.CustomerEntity的成员，修饰符为“public” at java.base / jdk.internal.reflect.Reflection.newIllegalAccessException（Unknown Source） at java.base / java.lang.reflect.AccessibleObject.checkAccess（Unknown Source）在java.base / java.lang.reflect.Method.invoke（未知来源）在com.microsoft.azure.storage.table.PropertyPair.generateEntityProperty（PropertyPair.java:291）在com.microsoft.azure.storage.table.TableServiceEntity.writeEntityWithReflection（TableServiceEntity.java:211）在com.microsoft.azure.storage.table.TableServiceEntity.writeEntity（TableServiceEntity.java:465）

Answer 1

引起：java.lang.IllegalAccessException：class com.microsoft.azure.storage.table.PropertyPair无法访问类table.CustomerEntity的成员，带有修饰符＆＃34; public＆＃34;

要序列化您的实体，您的CustomerEntity应该是公开的，因此应该在单独的文件中定义它。另请注意，不要在构造函数方法中声明属性。

以下是您可以参考的代码。

package table;
import com.microsoft.azure.storage.table.TableServiceEntity;

public class CustomerEntity extends TableServiceEntity {

public CustomerEntity(String lastName, String firstName) {
    this.partitionKey = lastName;
    this.rowKey = firstName;
}

public CustomerEntity() { }

String email;
String phoneNumber;

public String getEmail() {
    return this.email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getPhoneNumber() {
    return this.phoneNumber;
}

public void setPhoneNumber(String phoneNumber) {
    this.phoneNumber = phoneNumber;
}
}
