Question

我已经尝试了一些方法，但似乎是我正在做的事情。我创建了一个简单的Java类：

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "TRANSACTION")
@XmlAccessorType(XmlAccessType.FIELD)
public class CanonicalPropertyJaxb {

    @XmlAttribute
    protected String edbt;

    public String getEdbt() {
        return edbt;
    }

    public void setEdbt(String edbt) {
        this.edbt = edbt;
    }



}

这就是我收到的XML。我需要这个XML来生成Java对象和Java对象，以便在需要时生成相同的XML。所以我开始尝试从TRANSACTION标签获取EDBT属性，但它总是返回null。

<TRANSACTION ETYPE='JDEMCU' EDUS='IPAAS_ADM' EDBT='16919' EDTN='0' EDLN='2.000' EKEY='IPAAS_ADM-16919-0-2.000'>     <TABLE_1 NAME='F0006Z1' TYPE='1'>       <FORMAT_TABLE_F0006Z1 SEQ="1">

获取此信息的正确方法是什么？

Answer 1

JAXB区分大小写。因此，要么将字段更改为EDBT，要么将大写名称添加到@XmlAttribute(name="EDBT")。

我更喜欢后者，因为它符合java风格指南。

如何使用Jaxb从XML获取属性？
