Validated框架

Validated框架

spring-boot项目引入依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

实体类

@Data
public class OrderInfo {
    @NotNull(message = "Aid not null",groups = {AValidated.class})
    @NotNull(message = "Bid not null",groups = {BValidated.class})
    private String id;
    @Valid
    private Producted producted;
}

@Data
public class Producted {
    @NotNull(message = "proId not null")
    private String proId;
    private String proPrice;
}

可以通过groups进行分组

两个接口：AValidated 和BValidated
public interface AValidated {
}

public interface BValidated {
}

使用groups属性

对象参数前的@Validated(AValidated.class)表示会按OrderInfo中groups = {AValidated.class}的注解进行校验

@RestController
public class validatedController {

​ @PostMapping("/validatedTestA")
​ public void validatedTestA(@RequestBody @Validated(AValidated.class) OrderInfo info){
​ System.out.println(info);
​ }

​ @PostMapping("/validatedTestB")
​ public void validatedTestB(@RequestBody @Validated(BValidated.class) OrderInfo info){
​ System.out.println(info);
​ }
}

嵌套校验

对于OrderInfo的属性，只需要在类的成员变量上加校验注解即可

但如果要对OrderInfo的属性Producted中的属性进行校验，除了要在Producted中的属性加校验注解之外

最重要的是在Producted上加上 @Valid注解
