Spring Boot 官網(wǎng)關(guān)于數(shù)據(jù)校驗(yàn)例嘱，只有寥寥幾句，而且例子也相當(dāng)簡(jiǎn)單宁舰，如下：
@Service
@Validated
public class MyBean {
public Archive findByCodeAndAuthor(@Size(min = 8, max = 10) String code,
Author author) {
...
}
}
但在使用過(guò)程中拼卵，還是遇到一些問(wèn)題，下面記錄下使用記錄蛮艰，以防以后忘記腋腮。
首先看下 pom.xml 文件，詳細(xì)如下：

實(shí)例一
@Validated
@RestController
public class UserController {
@GetMapping("/users/{id}")
public String getUserById(@Min(value = 1, message = "參數(shù)不合法") @PathVariable("id") Long id) {
return "zhangsan";
}
}
- 注：
-
UserController類上面需要加@Validated注解
-
實(shí)例二
@Validated
@RestController
public class UserController {
@GetMapping(value = "/users")
public String listUsers(@Valid UserReq userReq, Errors errors) {
return "";
}
}
@Data
public class UserReq {
@NotNull(message = "不能為空")
private Long userId;
}
- 注：
-
UserReq類前面需要加@Valid注解壤蚜，否則UserReq類里面的校驗(yàn)不生效 -
UserReq類后面需要緊跟Errors類即寡，用于接收錯(cuò)誤，否則會(huì)一直報(bào)400錯(cuò)誤
-
