}解析如上复杂json：
private MovieDto getMovieDetailByUrl(String url){
MovieDto movieDto = new MovieDto();
ObjectMapper mapper = new ObjectMapper();
String responseBody = http(url);
if (!StringUtils.isEmpty(url)){
JsonNode movieNode = null;
try {
movieNode = mapper.readTree(responseBody);
movieDto.setTitle(movieNode.path("title").asText());
movieDto.setCoverImg(movieNode.path("images").path("large").asText());
movieDto.setAverage(movieNode.path("rating").path("average").asDouble());
movieDto.setStars(movieNode.path("rating").path("stars").asInt());
movieDto.setCountry(processArray(movieNode.get("countries")));
movieDto.setOriginalTitle(movieNode.path("original_title").asText());
movieDto.setWishCount(movieNode.path("wish_count").asInt());
movieDto.setCommentCount(movieNode.path("comments_count").asInt());
movieDto.setYear(movieNode.path("year").asText());
movieDto.setGenres(processArray(movieNode.get("genres")));
List<Person> directors = getPersons(movieNode.get("directors"));
movieDto.setDirectors(directors);
List<Person> casts = getPersons(movieNode.get("casts"));
movieDto.setCasts(casts);
movieDto.setSummary(movieNode.path("summary").asText());
} catch (IOException e) {
e.printStackTrace();
}
}
return movieDto;
}
关键点一：
对于节点中嵌套多个对象，此时已经无法通过 movieNode.path("casts") 来获取节点了，而需要通过 movieNode.get("casts") 获取节点，比如：
