知道Jackson可以做这个，只是不经常用到。用到了，查到了……

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
   
     lst =  (List
    
     )mapper.readValue(jsonString, javaType);
    
   

方法二:

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