Object转Map和Map转Object（对象转map，map转对象）
1FindArchiveDto findArchiveDto = new FindArchiveDto();
2findArchiveDto.setContractStatus("降龙");
3findArchiveDto.setCustName("明华");
4findArchiveDto.setDepartmentName("赵⽆极");
fastjson转换⽅法
1//Object转Map
2Map map = JSONObject.JSONString(findArchiveDto), Map.class);
3Map<String,Object> map = JSONObject.JSONString(findArchiveDto));
4//Map转Object
5FindArchiveDto findArchiveDto1 = JSON.JSONString(map), FindArchiveDto.class);
6FindArchiveDto findArchiveDto2 = JSONString(map), FindArchiveDto.class);
jackson的转换
1ObjectMapper mapper = new ObjectMapper();
2//对象转map
3Map m = adValue(mapper.writeValueAsString(findArchiveDto), Map.class);
4//map转对象
5FindArchiveDto dto = adValue(mapper.writeValueAsString(m), FindArchiveDto.class);
还可以⽤org.apachemons.beanutils.BeanMap进⾏转换
Map<String, Object> map = new org.apachemons.beanutils.BeanMap(findArchiveDto);
还可以⽤org.apachemons.beanutils.BeanUtils将map转为对象
BeanUtils.populate(findArchiveDto, map);
1//Object转Map
2public static Map<String, Object> getObjectToMap(Object obj) throws IllegalAccessException {
3    Map<String, Object> map = new LinkedHashMap<String, Object>();
4    Class<?> clazz = Class();
5    System.out.println(clazz);
6    for (Field field : DeclaredFields()) {
7        field.setAccessible(true);
8        String fieldName = Name();
9        Object value = (obj);
10        if (value == null){
11            value = "";
12        }
13        map.put(fieldName, value);
14    }
15    return map;
16}
1//Map转Object
2public static Object mapToObject(Map<Object, Object> map, Class<?> beanClass) throws Exception {
3    if (map == null)
4        return null;
5    Object obj = wInstance();
6    Field[] fields = Class().getDeclaredFields();
object to7    for (Field field : fields) {
8        int mod = Modifiers();
9        if (Modifier.isStatic(mod) || Modifier.isFinal(mod)) {
10            continue;
11        }
12        field.setAccessible(true);
13        if (Name())) {
14            field.set(obj, (Name()));
15        }
16    }
17    return obj;
18}
