分组示例
public interface First{}
public interface Second{}
public class User {
// 所有都验证
@NotNull(message = "...")
private int id;
// First 才验证
@NotNull(message = "...", groups = { First.class })
private String username;
// First 或 Second 才验证
@NotNull(message = "...", groups = { First.class, Second.class })
private String content;
// First 验证 NotEmpty，Second 验证 Size
@NotEmpty(message = "...", groups = { First.class })
@Size(message = "...", min = 3, max = 8, groups = { Second.class })
private String height;
}
// 只验证 Second 分组和没有分组的属性
public String save(@Validated( { Second.class }) User user, BindingResult result) {
if (result.hasErrors()) {
return "validate/error";
}
return "redirect:/success";
}
分组序列
public interface GroupA {}
public interface GroupB {}
@GroupSequence( { GroupA.class, GroupB.class })
public interface Group {}
public @ResponseBody String save(@Validated({ Group.class }) User user, BindingResult result) {
if(result.hasErrors()) {
return false;
}
return true;
}
嵌套验证
public class Item {
@NotNull(message = "id不能为空")
@Min(value = 1, message = "id必须为正整数")
private Long id;
@Valid
@NotNull(message = "props不能为空")
@Size(min = 1, message = "至少要有一个属性")
private List
}
public class Prop {
@NotNull(message = "pid不能为空")
@Min(value = 1, message = "pid必须为正整数")
private Long pid;
@NotNull(message = "vid不能为空")
@Min(value = 1, message = "vid必须为正整数")
private Long vid;
@NotBlank(message = "pidName不能为空")
private String pidName;
@NotBlank(message = "vidName不能为空")
private String vidName;
}
@RestController
public class ItemController {
@RequestMapping("/item/add")
public void addItem(@Validated Item item, BindingResult bindingResult) {
doSomething();
}
}
验证多个对象
@Controller
public class PeopleController {
@RequestMapping("/add")
public @ResponseBody String add(@Validated People pp, BindingResult result1, @Validated Person ps, BindingResult result2)
{
if(result1.hasErrors())
{
return false;
}
if(result2.hasErrors())
{
return false;
}
return true;
}
}
