# 提供Controller层参数校验

##一、使用

### 1、在controller上加上@ValidateGroup和内部的ValidateField注解即可实现校验

```java
    @ValidateGroup(fields = {
            @ValidateField(index = 0, notNull = true, showName = "a 符号a")
    })
    @RequestMapping(value = "/test")
    public Result test(String a){
        return new Result<>("", true, a);
    }
```

### 2、发送URL

```json
http://localhost:8080/value/test
```

> 2.1、得到返回值

```Json
{"message":"","success":false,"returnValue":"a 符号a 不能为空!"}
```

### 3、发送合法的URL

```Json
http://localhost:8080/value/test?a=1
```

> 3.1、得到返回值

```Json
{"message":"","success":true,"returnValue":"1"}
```



### 4、若为一个Bean，需要对其属性进行校验

```java
    @ValidateGroup(fields = {
            @ValidateField(index = 0,filedName = "value", notNull = true, showName = "value 属性value")
    })
    @RequestMapping(value = "/param", method = RequestMethod.POST)
    public Result param(@RequestBody Param param){
        return new Result<>("", true, param.getValue());
    }
```

> 4.1、则需要在validateField上添加一个fileName字段属性表明对应的对象属性
>
> 其中对象Param的类型格式为

```java
@Data
public class Param {
    private String value;
}
```

> 4.2、发送请求，其中value为空

```sh
curl --request POST \
  --url http://localhost:8080/value/param \
  --header 'content-type: application/json' \
  --data '{
	"value":""
}'
```

> 4.3、得到返回值为:

```json
{
  "message": "",
  "success": false,
  "returnValue": "value 属性value 不能为空!"
}
```
