创建一个Validator

Validator是Cloudopt Next的校验组件，主要用于RESTful注解上，与Intercept使用方法类似。

class TestValidator : Validator {
    override fun validate(resource: Resource): Boolean {
        return true
    }
    override fun error(resource: Resource) {
        resource.renderText("error")
    }
}

public class TestInterceptor implements Interceptor {
    @Override
    public boolean validate(Resource resource) {
        return true;
    }
    @NotNull
    @Override
    public void error(Resource resource) {
        resource.renderText("error");
    }
}

使用Validator

@GET(valid = arrayOf(TestValidator::class))

@GET(value = "/",valid = {TestValidator.class})
