sping中的controller接收實體參數時
如果實體中存在list屬性,當list數值過大時報錯
public class Model{ private List<String> strings; }
報錯信息:"Invalid property 'rynrlist[256]' of bean class [com.ac.intellsecurity.model.exam.records.ExamTrainingRecordsModel]: Index of out of bounds in property path 'rynrlist[256]'; nested exception is java.lang.IndexOutOfBoundsException: Index: 256, Size: 256"
報錯原因:
解決方法:
1.修改成jsonobject 接參數 然后轉成實體(推薦使用)
@RestController @RequestMapping("/controller") public class Controller { //原來的(修改前) @PostMapping("/addModel") public AjaxResult addModel(Model model){ //......... } //修改后 @PostMapping("/addModel") public AjaxResult addModel(JSONObject json){ //......... Model model = JSONObject.parseObject(json.toJSONString(),Model.class); } }
2. controller中添加方法
@InitBinder protected void initBinder(WebDataBinder binder) { binder.setAutoGrowNestedPaths(true); binder.setAutoGrowCollectionLimit(1024); }
