@Document在Spring Boot应用程序中未创建集合

如何解决@Document在Spring Boot应用程序中未创建集合

我有一个简单的spring boot rest应用程序。尝试在Spring Data Mongo db中使用@Document批注创建集合。我知道，如果文档使用@Document注释表示，则spring框架会创建一个集合。

实体

@Document("User")
public class User {
    @Id
    private String Id;
    @Field("firstName")
    @TextIndexed
    private String firstName;
    @Field("lastName")
    @TextIndexed
    private String lastName;
    private String address;

    public String getId() {
        return Id;
    }

    public void setId(String id) {
        Id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

属性

spring.data.mongodb.uri=mongodb://localhost:27017/Order

但是，在rest控制器中，它会在insert命令上创建一个集合，但仍然不会在insert上创建Text-index。

@RestController
public class Controller {
    private MongoTemplate mongoTemplate;

    public Controller(MongoTemplate mongoTemplate) {
        this.mongoTemplate = mongoTemplate;
    }

    @GetMapping("/get")
    public String Get(){
        mongoTemplate.insert(new User());
        return "HelloWorld";
    }
}

控制台中也没有任何错误

解决方法

我必须隐式设置工作

在application.properties文件中

spring.data.mongodb.auto-index-creation=true

或application.yml文件

spring:
  data:
    mongodb:
      auto-index-creation: true

参考-Please use 'MongoMappingContext#setAutoIndexCreation(boolean)' or override 'MongoConfigurationSupport#autoIndexCreation()' to be explicit
