Jackson 处理复杂类型(List,map)两种方法

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); 

String jsonString="[{'id':'1'},{'id':'2'}]";
ObjectMapper mapper = new ObjectMapper();
List<Bean> beanList = mapper.readValue(jsonString, new TypeReference<List<Bean>>() {});
