我用java 1.8，春季引導和MongoDB的一些數據存儲在數據庫中，以瞭解MongoDB的註釋是否可以限制java中類字段的字符？
我要限制通過註釋的類領域的人物，我試圖用Hibernate驗證器來控制這一點：
import javax.validation.constraints.Size;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
import org.springframework.data.mongodb.core.mapping.Field;
@Document(collection = "MusicGroup")
public class MusicGroup {
@Id
private String id;
@Size(min = 7, max = 7, message = "title need to have only 4 characters")
@Field("Title")
private String title;
@Size(min = 11, max = 11, message = "type need to have only 11 characters")
@Field("Type")
private String type;
@Field("Members")
private List<String> members;
public MusicGroup(String titulo, String tipo, List<String> integrantes) {
this.title = titulo;
this.type = tipo;
this.members = integrantes;
}
但是當我插入的MongoDB絲毫此驗證碼：
@Service
public class MusicGroupServiceImpl implements MusicGroupService {
@Autowired
private MusicGroupRepository repository;
public MusicGroupServiceImpl() {
}
@Override
public void storeGroup(){
String[] memberList = new String[3];
memberList[0] = "A";
memberList[1] = "B";
memberList[2] = "C";
MusicGroup group = new MusicGroup("Panteraaaaaa", "Heavy Metallllllllllllllll", memberList);
repository.save(group);
}
}
它的作品沒有任何問題的時候Panteraaaaaa的長度比7和重型Metallllllllllllllll相同更大

爲了實現這個問題 可以通過註釋來控制Java字段的字符長度德下面的代碼？或者我需要做一個方法來控制這個
你可以試試，如果從http://stackoverflow.com/questions/22568962/how-to接受的答案-i-get-spring-data-mongodb-to-validate-my-objects也適用於你？ – dunni
感謝您的評論，已解決的問題並不完全是我的問題的解決方案，但它引導了我，我將在幾分鐘內放入我所做的驗證字段大小的工作 – MaQuiNa1995
