在java中反编组时出错

Question

我有一个xml文件，

22

naveen **

我的POJO类是

String name;
int age;
int id;

public String getName() {
    return name;
}

public int getAge() {
    return age;
}

public int getId() {
    return id;
}

   File file = new File("sample.txt");
   JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
   Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
   Customer customer = (Customer) jaxbUnmarshaller.unmarshal(file);
   System.out.println(customer);

Answer 1

可能有2个问题
1-更正xml的格式，我可以在标记中看到空格，比如use而不是 更好地在xml下面使用

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<customer id="100">
    <age>22</age>
    <name>naveen</name> 
</customer>

2-并注释您的Jaxb类-使用下面的代码

@XmlRootElement
public class Customer {
@XmlElement
String name;
@XmlElement
int age;
@XmlAttribute
int id;

public String getName() {
    return name;
}

public int getAge() {
    return age;
}

public int getId() {
    return id;
}
}
