该方法主要用来处理删除数据之前的逻辑,如检验是否具有删除权限等,需要子类继承BaseCrudRestController时重写并实现具体处理逻辑。

|

## 数据校验
|
||||
|
||||
> 默认使用**hibernate-validator**进行后端数据校验。进行数据校验至少需要两步操作,在entity中设置每个字段的校验规则,以及在controller中对实体添加@Valid注解。
|
||||
|
||||
* 在entity中对字段进行校验规则的设置
|
||||
|
||||
```java
|
||||
@NotNull(message = "名称不能为空")
|
||||
@Length(max=100, message="名称长度应小于100")
|
||||
@TableField()
|
||||
private String name;
|
||||
```
|
||||
|
||||
* 在controller中添加@Valid注解
|
||||
|
||||
```java
|
||||
@PostMapping("/")
|
||||
public JsonResult createEntity(@Valid Demo entity, BindingResult result, HttpServletRequest request)
|
||||
throws Exception{
|
||||
return super.createEntity(entity, result);
|
||||
}
|
||||
```
|
||||
|
||||
* 如果您使用**json格式**进行数据提交,那么可以在@RequestBody注解前添加@Valid注解,如下:
|
||||
```java
|
||||
public JsonResult createEntity(@Valid @RequestBody Demo entity, BindingResult result, HttpServletRequest request)
|
||||
throws Exception{
|
||||
return super.createEntity(entity, result);
|
||||
}
|
||||
```
|
||||
