新增目录是自动生成id,不需要id参数;更新目录需要id,不能为空
pom.xml中已有spring-boot-starter-validation依赖
<!--validation(完成属性限制,参数校验)-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
实体类category
package com.yjzx.pojo;
import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;
import java.time.LocalDateTime;
@Data
public class Category {
@NotNull
private Integer cid;
@NotEmpty
private String categoryName;
@NotEmpty
private String categoryAlias;//别名
private Integer createUser;//用户ID
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private LocalDateTime createTime;
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private LocalDateTime updateTime;
}
新增目录Controller代码
@PostMapping
public Result add(@RequestBody @Validated Category category){
categoryService.add(category);
return Result.success();
}
更新目录Controller代码
@PutMapping
public Result update(@RequestBody @Validated Category category){
categoryService.update(category);
return Result.success();
}
??????? 通过validation分组校验
在category实体类中加入不同接口
//如果校验项未指定分组,默认Default分组
//分组之间可以继承,A extends B,那么A中有B的校验项
public interface Add extends Default {
}
public interface Update extends Default{
}
在区别属性前加入类似
@NotNull(groups = Update.class)
private Integer cid;
最后在Controller的校验中指定interface
@PostMapping
public Result add(@RequestBody @Validated(Category.Add.class) Category category){
categoryService.add(category);
return Result.success();
}
@PutMapping
public Result update(@RequestBody @Validated(Category.Update.class) Category category){
categoryService.update(category);
return Result.success();
}
即可完成分组校验
