xml格式化工具有哪些(ue格式化xml快捷键)

使用的javax这个jar下的类,JAXB(Java Architecture for XML Binding) 这个java和xml的互转标准如果感兴趣可以自行百度这里就不介绍概念,直接上代码。

xml格式化工具有哪些(ue格式化xml快捷键)


首先是工具类,这里比较简单,就没做生成实体文件,就是两个,一个对象转xml,一个xml转对像。

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;
import java.io.StringReader;
import java.io.StringWriter;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**

public class XmlUtils {

    /**
     * Description bean对像转换为xml字符串,
     * 对像属性如果不设置值,xml字符串没有节点,如果需要空节点,可以设置为空字符串
     * @param obj 需要转换的对像,转换的对像需要做对应的注解
     * @return java.lang.String

     **/
    public static String convertToXml(Object obj) {
        // 输出流
        StringWriter writer = new StringWriter();
        try {
            JAXBContext context = JAXBContext.newInstance(obj.getClass());
            Marshaller marshaller = context.createMarshaller();
            // 格式化xml输出的格式
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
            //marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.FALSE);
            // 设置编码集
            marshaller.setProperty(Marshaller.JAXB_ENCODING, "utf-8");
            // 将对象转换成输出流形式的xml
            marshaller.marshal(obj, writer);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return writer.toString();
    }

    /**
     * Description xml字符串转换为bean对像
     * @Author wangzhh
     * @Date 2022-06-13
     * @param clazz
     * @param xmlStr
     * @return java.lang.Object
     **/
    public static Object convertXmlStrToObject(Class clazz, String xmlStr) {

        Object xmlObject = null;
        try {
            JAXBContext context = JAXBContext.newInstance(clazz);
            // 进行将Xml转成对象
            Unmarshaller unmarshaller = context.createUnmarshaller();
            StringReader reader = new StringReader(xmlStr);
            xmlObject = unmarshaller.unmarshal(reader);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return xmlObject;
    }

    public static void main(String[] args) {
        TestXmlBean t = new TestXmlBean();
        t.setName("张三");
        t.setAge("");
        Map map = new HashMap();
        map.put("map","mapValue");
        t.setMsgMap(map);
        List listBean = new ArrayList();
        TestListBean t1 = new TestListBean();
        t1.setAddress("一号地址");
        TestListBean t2 = new TestListBean();
        t2.setAddress("二号地址");
        listBean.add(t1);
        listBean.add(t2);
        t.setListBean(listBean);
        System.out.println(XmlUtils.convertToXml(t));
        String xmlStr  = XmlUtils.convertToXml(t);
        xmlStr = "张三mapmapValue一号地址二号地址n";
        TestXmlBean bean = (TestXmlBean) XmlUtils.convertXmlStrToObject(TestXmlBean.class,xmlStr);
        System.out.println(bean.toString());
    }
}

测试用的类,饱含集合
