我想更新一个实体,该实体具有其他实体的一对多List集合。处理程序方法被调用时,验证似乎不在集合上运行。我已阅读文档,并搜索了stackoverflow,但没有发现任何有用的东西。Spring 3 mvc @Valid注解不适用于列表<Entity>属性
型号:
@Entity
public class Employee {
@Id
@GeneratedValue
private int employeeId;
@NotEmpty
private String name;
@Min(value=18)
private int age;
@OneToMany(mappedBy="parent",cascade=CascadeType.ALL)
private List<Child> children;
//getters,setters
}
@Entity
public class Child {
@Id
@GeneratedValue
private int childId;
@Column(nullable=false)
@NotNull
@Size(min=1,message="Child's name must not be empty")
private String childName;
@Max(value=18)
private Integer age;
@ManyToOne
@JoinColumn(name="employeeId")
private Employee parent;
//getters,setters
}
在控制器:
@RequestMapping(value = { "/edit/{id}" }, method = RequestMethod.POST)
private String update(@PathVariable int id, ModelMap model, @Valid Employee employee, BindingResult result) {
if (result.hasErrors()) {
return "employee/edit";
}
employeeDao.merge(employee);
return "redirect:../list";
}
验证工作的员工bean的简单性,而不是在孩子列表中的元素。
这怎么解决?
