Question

我是Play的新手，我想尝试从JSON帖子绑定一个String列表。

我执行以下操作：

import play.data.validation.Constraints;
import java.util.ArrayList;
import java.util.List;

Form<Person> PERSON = new Form<>(Person.class);
Form<Person> filledForm = PERSON.bind(request().body().asJson());

Person class {

  @Constraints.Required
  @Constraints.Email
  private String email;

  @Constraints.Required
  private List<String> adresses = new ArrayList<>();

}

我收到以下消息：

"matches":[
"This field is required"
]

Answer 1

此行会导致问题：

Form<Person> filledForm = PERSON.bind(request().body().asJson());

将其替换为：

Form<Person> filledForm = PERSON.bindFromRequest();
