方法一:
String jsonString="[{'id':'1'},{'id':'2'}]"; ObjectMapper mapper = new ObjectMapper(); JavaType javaType = mapper.getTypeFactory().constructParametricType(List.class, Bean.class); //如果是Map类型 mapper.getTypeFactory().constructParametricType(HashMap.class,String.class, Bean.class); List<Bean> lst = (List<Bean>)mapper.readValue(jsonString, javaType);
方法二:
String jsonString="[{'id':'1'},{'id':'2'}]"; ObjectMapper mapper = new ObjectMapper(); List<Bean> beanList = mapper.readValue(jsonString, new TypeReference<List<Bean>>() {});
