JSON parse error: Cannot deserialize value of type

做项目的时候遇到这个问题

JSON parse error: Cannot deserialize value of type `com.lqkj.gis.web.cmgis.modules.elasticsearch.domain.SystemType` 
from String "": value not one of declared Enum instance names:
 [cmphs, cmm7721, cmnet, org, cmmas, cms1719, zhuantitu, map, pubpoi, cmphsStaff, cmvdm, cmvec];
  nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type

查询后原因在于数据是枚举类型，不能为空 解决方案： 由于用于请求的数据是个对象，考虑在请求数据的方法中对对象数据进行处理 handleIndex() { console.log(“进入更新操作”); var newlistquery = { page: 0, pageSize: 10, systemType : “”, zoneid : “”, name : “” } this.$set(this, “listQuery”, newlistquery); delete this.listQuery.systemType; // 对象中删除属性 delete this.listQuery.zoneid; console.log(“经过处理后的listQuery:”, this.listQuery) this.getList(); }

利用delete删除对象数据的属性
