Question

我有一个springboot应用程序正在与一个mongo数据库交谈，其中一个集合有点“非结构化”。该集合都与“app config”相关，但不同的应用程序在那里有不同的东西。有些应用程序在顶层只有一些东西，有些具有深层嵌套文档。

如果有一些常见的“顶级”文档，我会有一个类似于@Id String id的类，然后是Map<String, Object> info或其他什么，但“灵活”数据在顶层。那么，我可以像使用MongoRepository<Map<String,Object>, String>之类的东西来扩展MongoRepository吗？有没有更好的方法来处理这样的事情？

如果你想用springboot构建Rest服务，请按照下面给出的示例代码。这是我在Springboot中找到CRUD的最简单方法

1）使用spring初始化程序下载spring项目（例如：com.library.demo）

2）其余的作为下面的示例代码

<强> application.properties

server.port=8091
spring.data.mongodb.uri=mongodb://localhost:27017/<databaseName>

<强> com.library.demo.model-＆GT; Book.java

package com.librarysystem.demo.model;

import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection="booklist")
public class Book {
    @Id
    String _id;
    String Name;
    String ISBN;
    String Author;

public Book(String Name,String ISBN,String Author) {
    this.Name=Name;
    this.ISBN=ISBN;
    this.Author=Author;
}

public String getName() {
    return Name;
}

public void setName(String name) {
    Name = name;
}

public String getISBN() {
    return ISBN;
}

public void setISBN(String iSBN) {
    ISBN = iSBN;
}

public String getAuthor() {
    return Author;
}

public void setAuthor(String author) {
    Author = author;
}
}

<强> com.library.demo.repository-＆GT; BookRepository.java

 import com.librarysystem.demo.model.Book;

@Repository
public interface BookRepository extends MongoRepository<Book, String>{
    public Book findByName(String BookName);
}

<强> com.library.demo.service-＆GT; BookService.java

import com.librarysystem.demo.repository.BookRepository;

@Service
public class BookService {

@Autowired
private BookRepository bookrepository;

public Book create(String Name,String ISBN,String Author) {
    return bookrepository.save(new Book(Name,ISBN,Author));
}

public Book getByBookName(String name) {
    return bookrepository.findByName(name);
}
public List<Book>getAll(){
    return bookrepository.findAll();
}


public void delete(String Name) {
    Book b=bookrepository.findByName(Name);
    bookrepository.delete(b);
}

}

<强> com.library.demo.controller-＆GT; BookController.java

import com.librarysystem.demo.service.BookService;

@RestController
public class BookController {

    @Autowired
    private BookService bookservice;

 @RequestMapping("/create")
 public String create(@RequestParam String Name,@RequestParam String ISBN,@RequestParam String Author) {
    Book b=bookservice.create(Name, ISBN, Author);
    return b.toString();
}

@RequestMapping("/get")
public Book getBook(@RequestParam String Name) {
    return bookservice.getByBookName(Name);
}

@RequestMapping("/getAll")
public List getBook() {
    return bookservice.getAll();
}

@RequestMapping("/delete")
public String delete(@RequestParam String name) {
    bookservice.delete(name);
    return "deleted"+name;
    }
}

希望这包含您在一个地方需要的一切
