使用 ValidationApi 进行参数校验

导入依赖：

<dependency> <groupId>javax.validation</groupId> <artifactId>validation-api</artifactId> <version>2.0.1.Final</version> </dependency>

实战：

import java.io.Serializable; import javax.validation.Valid; import javax.validation.constraints.Min; import javax.validation.constraints.NotNull; import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; import lombok.Data; @Data @ApiModel(value = "分页服务请求") public class PageRequest<T> implements Serializable { @ApiModelProperty(value = "请求令牌") private String token; @ApiModelProperty(value = "每页大小") @Min(value = 1, message = "分页大小不得小于1") private int pageSize = 10; @ApiModelProperty(value = "请求页数") @Min(value = 1, message = "页码不得小于1") private int page = 1; @ApiModelProperty(value = "请求参数") @NotNull(message = "params不能为空") @Valid private T params; }
