在java中創建xml更快xml

Question

我正在使用fasterxml.jackson使用POJO創建xml。

我期待輸出如下：

<Customer xmlns=""> 
    <firstname>FirstNameA</firstname> 
    <middlename>LastNameA</middlename> 
</Customer> 

But getting output as: 
<Customer xmlns=""> 
    <item> 
     <firstname>FirstNameA</firstname> 
     <middlename>LastNameA</middlename> 
    </item> 
</Customer> 

爲什麼會追加<item>標籤。我沒有在任何地方添加<item>標記，但輸出顯示爲<item>標記。我的代碼中存在哪些錯誤？

這是POJO

@JacksonXmlRootElement(localName = "Customer") 
    public class Customer { 
     @JacksonXmlProperty(localName="firstname") 
     private String firstname; 

     @JacksonXmlProperty(localName="middlename") 
     private String middlename; 


     public Customer(String firstname, String middlename) { 
      this.firstname = firstname; 
      this.middlename = middlename; 
     } 
} 

// code to create xml 
    ObjectMapper xmlMapper = new XmlMapper(); 
      JacksonXmlModule module = new JacksonXmlModule(); 
      module.setDefaultUseWrapper(false); 
      Customer[] cust = new Customer[]{new Customer("FirstNameA", "LastNameA")}; 
      try { 
       String xml = xmlMapper.writeValueAsString(cust); 
       return xml; 
      } catch (JsonProcessingException e) { 
       e.printStackTrace(); 
      }

客戶在你的代碼是一個數組，你不能在您發佈的XML樣式添加多個項目：

<Customer xmlns=""> 
    <firstname>FirstNameA</firstname> 
    <middlename>LastNameA</middlename> 
</Customer> 

只需更換你的代碼：

Customer cust = new Customer("FirstNameA", "LastNameA");
