先要引入对应的jar,然后调用net.sf.json库的
ObjectMapper mapper = new ObjectMapper(); JavaType javaType = mapper.getTypeFactory().constructParametricType(List.class, ApprWritUnionFormModel.class); /*List<FormModel> writUnionFormList = JSON.parseArray(params, FormModel.class);*/ List<FormModel> writUnionFormList=new ArrayList<FormModel>(); try { writUnionFormList = (List<FormModel>)mapper.readValue(params, javaType); } catch (JsonParseException e) { e.printStackTrace(); } catch (JsonMappingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }
fastjson的简单用法,fastjson转换相对语法简单点,不过如果出现Bean类过大,或者在ie模式有时候会出现一些报错
List<FormModel> writUnionFormList = JSON.parseArray(params, FormModel.class);
