javabean转map 利用cglib的BeanMap类实现转换

import org.springframework.cglib.beans.BeanMap; /** * * @Title: beanToMap * @Description: javabean转map * @param bean * @return */ public static Map beanToMap(T bean) { Map beanMap = new HashMap<>(16); if (bean != null) { BeanMap tempMap = BeanMap.create(bean); for (Object key : tempMap.keySet()) { String putKey = String.valueOf(key); Object putValue = https://www.it610.com/article/tempMap.get(key); beanMap.put(putKey, putValue); } } return beanMap; }/** * * @Title: beanListToMapList * @Description: List转换为List * @param beanList * @return */ public static List beanToMapBatch(List beanList) { List beanMapList = new ArrayList<>(16); if (beanList != null && beanList.size() > 0) { for (T bean : beanList) { Map beanMap = beanToMap(bean); beanMapList.add(beanMap); } } return beanMapList; }

map转javabean 利用cglib的BeanMap类实现转换

import org.springframework.cglib.beans.BeanMap; /** * * @Title: mapToBean * @Description: map转javabean * @param beanMap * @param bean * @return */ public static T mapToBean(Map beanMap, T bean) { BeanMap tempMap = BeanMap.create(bean); tempMap.putAll(beanMap); return bean; }/** * * @Title: mapToBean * @Description: map转javabean * @param beanMap * @param beanClass * @return * @throws InstantiationException * @throws IllegalAccessException */ public static T mapToBean(Map beanMap, Class beanClass)throws InstantiationException, IllegalAccessException { T bean = beanClass.newInstance(); BeanMap tempMap = BeanMap.create(bean); tempMap.putAll(beanMap); return bean; }/** * * @Title: mapToBeanBatch * @Description: List转List * @param beanMap * @param beanClass * @return * @throws IllegalAccessException * @throws InstantiationException */ public static List mapToBeanBatch(List beanMap, Class beanClass) throws InstantiationException, IllegalAccessException { List beanList = new ArrayList<>(16); if (beanMap != null && beanMap.size() > 0) { for (Map tempMap : beanMap) { T bean = mapToBean(tempMap, beanClass); beanList.add(bean); } } return beanList; }

xml转map 使用dom4j

/** * * @Title: parseXmlToMap * @Description: 解析xml，并返回map * @return * @throws IOException * @throws DocumentException */ public static Map parseXmlToMap(HttpServletRequest request) throws IOException, DocumentException { // 将解析的结果存入map集合中 Map map = new HashMap<>(16); // 从request中获取流 InputStream inputStream = request.getInputStream(); // 使用dom4j读取输入流 SAXReader reader = new SAXReader(); Document document = reader.read(inputStream); // 得到xml根元素 Element root = document.getRootElement(); // 得到根元素的所有子节点 List elementList = root.elements(); // 迭代 for (Element e : elementList) { map.put(e.getName(), e.getText()); } inputStream.close(); inputStream = null; return map; }

xml转bean 【工具类|javabean、xml、json、map之间的相互转换】使用jackson

/** * * @Title: xmlToBean * @Description: xml转换成bean * @param request * @param beanClass * @return * @throws IOException */ public static T xmlToBean(HttpServletRequest request, Class beanClass) throws IOException { // 获取输入流 InputStream inputStream = request.getInputStream(); XmlMapper xmlMapper = new XmlMapper(); T bean = xmlMapper.readValue(inputStream, beanClass); inputStream.close(); inputStream = null; return bean; }jackson相关注解 @JacksonXmlRootElement(localName = "xml") public class TextMessage implements Serializable { /** * 序列化 */ private static final long serialVersionUID = 2501424341457570501L; /** * 开发者微信号 */ @JacksonXmlProperty(localName = "ToUserName") @JacksonXmlCData(value = https://www.it610.com/article/true) private String ToUserName; .... }
