业务参数校验
业务参数校验采用JSR-303方式,关于JSR-303介绍可以参考这篇博文:JSR 303 - Bean Validation 介绍及最佳实践
在参数中使用注解即可,框架会自动进行验证。如下面一个添加商品接口,它的参数是GoodsParam
@ApiMapping(value = "goods.add")
public void addGoods(GoodsParam param) {
...
}
在GoodsParam中添加JSR-303注解:
@Data
public class GoodsParam {
@NotEmpty(message = "商品名称不能为空")
private String goods_name;
}
如果不传商品名称则返回
{"goods_add_response":{"msg":"Success","code":"10000","sub_msg":"商品名称不能为空","sub_code":"isv.invalid-parameter"},"sign":"Eh3Z5CxDCHsb4MyYFVxsPSmBpwVi1LISJdOkrzglxXoqG7RVyEOt4ef1kNpznUvMI3FDQU1suR7Rsmx6NjGdEVS6NSH2Kt0d8TFBRpLhWz8hApnxOtgzqMqbYeMuJie7X5gF6m8hTnvuuxF21IrkixMe+lyBcXw7dk0C3w1SwdEZkHQ+xC+M4bLqAZt5/3kl79/FWSMFJWHiZmg5YeEi8e8XhYCNcz+xlJRJL0x2Y87fFxqSY0UYWNxbQHgdVI8xRfn1n31nzkcLxiAtTh4LPtNRrG7w7absK/C1Oi/vczuBlFeq2EWUsYVWOVpKiJifUwvYVUUsztSLElzplzOjbg=="}
参数校验国际化
国际化的配置方式如下:
@NotEmpty(message = "{goods.remark.notNull}")
private String goods_remark;
国际化资源文件bizerror_en.properties
中添加:
goods.remark.notNull=The goods_remark can not be null
bizerror_zh_CN.properties中添加:
# 商品备注不能为空
goods.remark.notNull=\u5546\u54c1\u5907\u6ce8\u4e0d\u80fd\u4e3a\u7a7a
参数校验国际化传参
下面校验商品评论的长度,要求大于等于3且小于等于20。数字3和20要填充到国际化资源中去。
// 传参的格式:{xxx}=value1,value2...
@Length(min = 3, max = 20, message = "{goods.comment.length}=3,20")
private String goods_comment;
bizerror_en.properties:
goods.comment.length=The goods_comment length must >= {0} and <= {1}
bizerror_zh_CN.properties中添加:
# 商品评论长度必须在{0}和{1}之间
goods.comment.length=\u5546\u54c1\u8bc4\u8bba\u957f\u5ea6\u5fc5\u987b\u5728{0}\u548c{1}\u4e4b\u95f4
这样value1,value2会分别填充到{0},{1}中
