### 简介

java bean基于注解的校验框架，由于要使用openstack java sdk，而openstack本身是支持多个版本的，

所以需要同一个实体类按版本号进行不同的校验，所以java/spring自带的校验工具并不能满足需求,所以

手撸了一个简易的可以分版本校验的通用框架。（目前只支持了notNull注解，后续根据工作需求会同步更新

，或者有人使用后可以提PR）

### 使用说明

#### 1. 添加注解

````java

@Data

public class Project {

    @NotNull(version = 2.8)

    private String projectId;

}

````

#### 2.调用校验

````java

class test{

    public static void main(String[] args){

      IResult result=ValidFactory.on(value,version,group).valid().result();

      //控制台打印结果

      result.print();

      if(!result.pass()){

          result.throwsEx();

      }

    }

}

````

### 增加其他校验流程

#### 1. 重写AbstractAnnotationCondition

 

 ````java

public class NotNullCondition extends AbstractAnnotationCondition {

    @Override

    protected ICondition buildCondition(NotNull annotation) {

        return new NotNullConditionImpl(annotation);

    }

    static class NotNullConditionImpl implements ICondition{

        NotNull notNull;

        private NotNullConditionImpl(NotNull notNull) {

            this.notNull = notNull;

        }

        @Override

        public boolean condition(IConditionContext conditionContext) {

            double version=notNull.version();

            double validVersion=conditionContext.version();

            if(validVersion groupList= Arrays.asList(group);

                groupList.retainAll(Arrays.asList(validGroup));

                if(groupList.size()==0){

                    //不在校验范围内，跳出

                    return true;

                }

            }

            return !StringUtils.isEmpty(conditionContext.value());

        }

    }

}

````   

#### 2. 编写自定义注解，来指定校验所用的类

````java

@Inherited

@Documented

@Target(ElementType.FIELD)

@Retention(RetentionPolicy.RUNTIME)

@Condition(NotNullCondition.class)

public @interface NotNull {

    /**

     * 校验的起始版本号

     * @return 版本号

     */

    double version();

    /**

     * 校验的分组

     * @return 校验的分组

     */

    Class[] group() default {};

    String message() default "%s Must Not NUll";

}
