【问题描述】：
我的项目基于spring boot、Thymeleaf、mysql、html和Jquery。
我尝试将 EntSetCharges 列表 类型的数据发布到@controller，但它不成功..它会像
那样引发错误java.lang.IllegalStateException: 找不到主构造函数 java.util.List
现在我在同一页面中遇到另一个错误
这是我的完整代码...

}
Boolean result = serSetCharges.doUpdateSetCharges(entSetChargesList);
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return respondResult;
}
实体

@Table(name="setcharges")
public class EntSetCharges implements Serializable
{
/**

private static final long serialVersionUID = 3827507518731160293L;
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="pksetcharges")
private int pkSetCharges;

@Transient
private String tempunitType;
@Transient
private String tempUnitAmount;
@Transient
private LogEntSetCharges tempLogEntSetCharges;
代码更新 V1 在这里我做了一些更改，它正在访问控制器页面，但是对象是 EMPTY [] ..这是图像证明 @RestController
@PostMapping(value="/updatesetcharges")
public ModelAndView doUpdateSetCharges(@ModelAttribute WrpSetCharges tempEntSetChargesList)
{
ModelAndView respondResult = new ModelAndView();
try {
List<EntSetCharges> entSetChargesList = new ArrayList<>();
for(EntSetCharges ent : tempEntSetChargesList.getTempEntSetChargesList())
{ //logics goes here
在 HTML 中
<form id="setchargesformid" method="post" th:object="${tempEntSetChargesList}" th:action="@{/updatesetcharges}">
包装类
public class WrpSetCharges {
private List<EntSetCharges> tempEntSetChargesList = new ArrayList<>();
public List<EntSetCharges> getTempEntSetChargesList() {
return tempEntSetChargesList;
}
public void setTempEntSetChargesList(List<EntSetCharges> tempEntSetChargesList) {
this.tempEntSetChargesList = tempEntSetChargesList;
}
}
