使用fastJson将json转换成javaBean集合(list＜T＞)

废话不说，上json串

jsonStr = [{"MATERIAL_ID_":"10000021020033","MATERIAL_NO_":"051001175-3213-00002","MATERIAL_CLASSIFY_":"钻头","DESCRIPTION_":"【长度：15】","UNIT_":"付","PLAN_TO_USE_":20},{"MATERIAL_ID_":"10000021020038","MATERIAL_NO_":"051001150-213132-00003","MATERIAL_CLASSIFY_":"石头","DESCRIPTION_":"【长度：213】","UNIT_":"吨","PLAN_TO_USE_":200},{"MATERIAL_ID_":"10000030931347","MATERIAL_NO_":"050502001-SDDSA-00006","MATERIAL_CLASSIFY_":"木头","DESCRIPTION_":"【长度：213】","UNIT_":"根","PLAN_TO_USE_":150},{"PLAN_TO_USE_":"","DESCRIPTION_":"【长度：123】","UNIT_":"公斤","MATERIAL_NO_":"051001175-333-00001","MATERIAL_CLASSIFY_":"钻头","MATERIAL_ID_":"10000021020030"}]

这个json里有三条数据，往往需要将其转换成list集合，这里使用fastJson，只需要两行代码

JSONArray array = JSONArray.parseArray(jsonStr);
List<MsProposedVo> mpvList = JSONObject.parseArray(array.toJSONString(), MsProposedVo.class);

MsProposedVo 实体类中的属性命名(特殊情况这么写了，正常情况下建议使用小写、驼峰命名法)

着重注意，json串里的字段要和list的泛型的对象的字段一致，否则调试时，上述写法只会输出对应个数的集合，但是集合里的字段值都为null
