使用循环遍历方式实现List拷贝属性 首先我们来看一下使用循环遍历方式实现List拷贝属性的代码示例: publicclassCopyListPropertyDemo{publicstaticvoidcopyListProperties(List<SourceObject>sourceList,List<TargetObject>targetList){for(inti=0;i
List userDOList = new ArrayList(); userDOList.add(new UserDO(1L, "Van", 18, 1)); userDOList.add(new UserDO(2L, "VanVan", 20, 2)); List userVOList = BeanUtilCopy.copyListProperties(userDOList, UserVO::new, (userDO, userVO) -> { // 这里可以定义特定的转换规则 userVO.setSex(S...
publicstatic<T>List<T> copyListProperties(List<?> sourceList,Class<T>targetClass)throwsException{ if(CollectionUtils.isNotEmpty(sourceList)) { List<T>list=newArrayList<T>(sourceList.size); for(Object source : sourceList) { T target = copyProperties(source, targetClass); list.add(target); }...
beanCopier.copy(source, target,null); }/** * 不同类型对象数据copylist * *@paramsourceList*@paramtargetClass*@param<T> *@return*/publicstatic<T>List<T>copyListProperties(List<?> sourceList,Class<T> targetClass) throwsException{if(CollectionUtils.isNotEmpty(sourceList)) {List<T> list =new...
}returnCollections.emptyList(); }publicstaticMap<String,Object>json2Map(StringjsonStr) {MapLikeTypemapLikeType = objectMapper.getTypeFactory().constructMapLikeType(HashMap.class,String.class,Object.class);try{returnobjectMapper.readValue(jsonStr, mapLikeType); ...
stringPropertyNames：获取所有键的集合。添加属性：setProperty：添加或修改属性，与put方法类似。打印输出：list：将属性内容打印到输出流。保存属性：store：将属性保存到输出流，格式为properties。storeToXML：将属性保存为XML格式的文件。通过这些步骤和特性，Java程序可以方便地读取、操作以及保存properties...
