java - 使用 itemReader Spring Batch 读取 XML 中节点的属性

Question

下面有一个 xml

<?xml version="1.0" encoding="UTF-8"?>
<employee siteId="1">
   <name>john</name>
   <age>36</age>
</employee>

我想使用 itemReader 获取 siteId 的值(属性值)。我能够成功读取 name 和 age 子元素。我不知道如何获取siteId的值。请帮忙。谢谢!

您可以通过在类中指定 @XmlAttribute(name = "siteId") 来读取 siteId 属性值，请参阅下面的示例

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name = "employee")
public class Employee {

    private int siteId;
    private String name;
    private int age;


    @XmlAttribute(name = "siteId")
    public int getSiteId() {
        return siteId;
    }

    public void setSiteId(int siteId) {
        this.siteId= siteId;
    }

    @XmlElement(name = "age")
    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @XmlElement
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}
