上面两个问题主要都是DictAspect.parseDictText出现问题，具体看就是这个函数里面的一个日期转换到string出问题，目前不需要了，可以注释掉了，注释掉后正常，代码如下：文章来源地址https://www.toymoban.com/news/detail-660334.html
private void parseDictText(Object result) {
if (result instanceof Result) {
if (((Result) result).getResult() instanceof IPage) {
List<JSONObject> items = new ArrayList<>();
//step.1 筛选出加了 Dict 注解的字段列表
List<Field> dictFieldList = new ArrayList<>();
// 字典数据列表， key = 字典code，value=数据列表
Map<String, List<String>> dataListMap = new HashMap<>();
for (Object record : ((IPage) ((Result) result).getResult()).getRecords()) {
ObjectMapper mapper = new ObjectMapper();
String json="{}";
try {
//解决@JsonFormat注解解析不了的问题详见SysAnnouncement类的@JsonFormat
//json = mapper.writeValueAsString(record); //改用objectMapper,解决java8 LocalDateTime JSON解析问题
json = objectMapper.writeValueAsString(record);
} catch (JsonProcessingException e) {
log.error("json解析失败"+e.getMessage(),e);
}
JSONObject item = JSONObject.parseObject(json);
//update-begin--Author:scott -- Date:20190603 ----for：解决继承实体字段无法翻译问题------
//for (Field field : record.getClass().getDeclaredFields()) {
// 遍历所有字段，把字典Code取出来，放到 map 里
for (Field field : oConvertUtils.getAllFields(record)) {
String value = item.getString(field.getName());
if (oConvertUtils.isEmpty(value)) {
continue;
}
//update-end--Author:scott -- Date:20190603 ----for：解决继承实体字段无法翻译问题------
if (field.getAnnotation(Dict.class) != null) {
if (!dictFieldList.contains(field)) {
dictFieldList.add(field);
}
String code = field.getAnnotation(Dict.class).dicCode();
String text = field.getAnnotation(Dict.class).dicText();
String table = field.getAnnotation(Dict.class).dictTable();
List<String> dataList;
String dictCode = code;
if (!StringUtils.isEmpty(table)) {
dictCode = String.format("%s,%s,%s", table, text, code);
}
dataList = dataListMap.computeIfAbsent(dictCode, k -> new ArrayList<>());
this.listAddAllDeduplicate(dataList, Arrays.asList(value.split(",")));
}
//date类型默认转换string格式化日期
/*if (field.getType().getName().equals("java.util.Date")&&field.getAnnotation(JsonFormat.class)==null&&item.get(field.getName())!=null){
SimpleDateFormat aDate=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
item.put(field.getName(), aDate.format(new Date((Long) item.get(field.getName()))));
}*/
}
items.add(item);
}
//step.2 调用翻译方法，一次性翻译
Map<String, List<DictModel>> translText = this.translateAllDict(dataListMap);
//step.3 将翻译结果填充到返回结果里
for (JSONObject record : items) {
for (Field field : dictFieldList) {
String code = field.getAnnotation(Dict.class).dicCode();
String text = field.getAnnotation(Dict.class).dicText();
String table = field.getAnnotation(Dict.class).dictTable();
String fieldDictCode = code;
if (!StringUtils.isEmpty(table)) {
fieldDictCode = String.format("%s,%s,%s", table, text, code);
}
String value = record.getString(field.getName());
if (oConvertUtils.isNotEmpty(value)) {
List<DictModel> dictModels = translText.get(fieldDictCode);
if(dictModels==null || dictModels.size()==0){
continue;
}
String textValue = this.translDictText(dictModels, value);
log.debug(" 字典Val : " + textValue);
log.debug(" __翻译字典字段__ " + field.getName() + CommonConstant.DICT_TEXT_SUFFIX + "： " + textValue);
// TODO-sun 测试输出，待删
log.debug(" ---- dictCode: " + fieldDictCode);
log.debug(" ---- value: " + value);
log.debug(" ----- text: " + textValue);
log.debug(" ---- dictModels: " + JSON.toJSONString(dictModels));
record.put(field.getName() + CommonConstant.DICT_TEXT_SUFFIX, textValue);
}
}
}
((IPage) ((Result) result).getResult()).setRecords(items);
}
