Springfox Java Bean Validations 未在 Swagger Output 中显示

Question

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@EnableSwagger2
@Import({springfox.bean.validators.configuration.BeanValidatorPluginsConfiguration.class})
@Configuration
public class SwaggerConfig {
    @Bean
    public Docket docket() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("My API")
                .build();
    }
}

这是我的请求映射：

@ApiOperation(value = "Use to get token for internal applications")
@PostMapping(value = AuthUris.TOKEN)
public AuthResponse token(@Valid @RequestBody AuthRequest authRequest) {
// implementation omitted
}

这是我的POJO:

@ApiModel
public class AuthRequest {
    @ApiModelProperty
    @NotNull
    @Size(min = 4, max = 50)
    private String username;
    @NotNull
    private String password;

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

我期望在Swagger UI中捕获NotNull和Size注释，但是它们没有。请帮助我理解这应该如何工作。谢谢你。

如果您使用的是 springfox 2.7.0 版，则@NotNull和@Size注释都应该有效。

您的< code>@NotNull批注已经在< code >密码字段中起作用。

如果字段存在@ApiModelProperty注释，则该注释优先于@NotNull。用户名字段就是这种情况。它显示为可选，因为@ApiModelProperty注释的必需属性默认设置为false。

例如，如果输入的用户名小于最小大小4，则会出现以下异常：
