Question

我得到了什么

这是我在mongoDB中保存的对话框集合

"_id": "5a61c7c7d5981a4b88b5fe17",
"_class": "com.kalsym.next.gen.campaign.data.Dialog",
"message": {
    "title": "Welcome Message",
    "subTitle": "Click SUbscribe to avail the offer",
    "url": "www.hotmail.com"
},
"options": [{
    "IR": "Thanks for subscription",
    "value": "sub",
    "path": "sub"
},
{
    "IR": "www.kalsym.com/NoThanks",
    "value": "NoThnks",
    "path": "NT"
}]

我想要的是什么：

"_id": "5a4e16547d4cea1604bf28f8",
"message": {
    "Title": "",
    "SubTitle": "Do you want to talk to CSR?",
    "URL": ""
},
"options": {
    "Yes": {
        "IR": "You will get a callback within 1 hour, thanks.",
        "value": "Yes",
        "path": "NT\\NotNow\\Yes"
    },
    "No": {
        "IR": "No Problem, have a good day!",
        "value": "No",
        "path": "NT\\NotNow\\No"
    }
}

问题在于“选项”字段。我希望它是一个键值对，而不是一个简单的列表。

这是我的Dialog类：

import java.util.List;
import lombok.Getter;
import lombok.Setter;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Getter     
@Setter
@Document(collection = "Dialog")
public class Dialog {
    @Id
    public String id;
    private Message message;
    private List<Option> options;

    public Dialog(final Message message, final List<Option> options) {
        this.message = message;
        this.options = options;
    }
}

这是Message类：

import lombok.Getter;
import lombok.Setter;
import lombok.ToString;

@Getter
@Setter
@ToString
public class Message {

    private String title;
    private String subTitle;
    private String url;

    public Message(final String title, final String subTitle, final String url) {
        this.title = title;
        this.subTitle = subTitle;
        this.url = url;
        }

}

这是选项类：

import lombok.Getter;
import lombok.Setter;
import lombok.ToString;

@Getter
@Setter
@ToString
public class Option {
    private String IR;
    private String value;
    private String path;

    public Option(final String IR, final String value, final String path) {
        this.IR = IR;
        this.value = value;
        this.path = path;
    }
}

以下是我如何保存它：

@SpringBootApplication
@EnableMongoRepositories(basePackageClasses = DialogRepository.class)
public class CampaignAPI implements CommandLineRunner {

    @Autowired
    private DialogRepository dialogRepository;

    public static void main(String[] args) {
        SpringApplication.run(CampaignAPI.class, args);
    }

    @Override
    public void run(String... strings) throws Exception {

        Message msg = new Message("Welcome Message", "Click SUbscribe to avail the offer", "www.hotmail.com");
        final Option subscribe = new Option("Thanks for subscription", "sub", "sub");
        final Option noThanks = new Option("www.kalsym.com/NoThanks", "NoThnks", "NT");
        List<Option> options = Arrays.asList(subscribe, noThanks);

        final Dialog welcomeDialog = new Dialog(msg, options);
        dialogRepository.save(welcomeDialog);

    }
}

我的问题

我希望如何保存它有什么不对吗？即架构是否正确？（想要在选项对象中保存键/值对）
即使是错误的，我如何保存它与我上面粘贴的预期mongo文档完全一样。

Answer 1

这应该产生预期的JSON。

public class Dialog { @Id public String id; private Message message; private Option Yes; private Option No; }

列表元素没有密钥，它们只在内存中有价值和位置。这就是你不想要List的原因。

使用spring在mongoDB中创建嵌套文档
