如何使用mongodb應用程序在spring boot中修復UnsatisfiedDependencyException？

Question

我正在嘗試將我的Spring啟動應用程序DB從H2更改為MongoDB。 我更新了application.properties文件並刪除了所有“@Entity”和“@Column”並添加了“@Document”。 我得到的錯誤是：

描述：

smartspace.dao.rdb.RdbActionDao中構造函數的參數0需要一個名為“mongoTemplate”的bean，該bean無法找到。

行動：

考慮在配置中定義名為“mongoTemplate”的bean。

Action:

Consider defining a bean named 'mongoTemplate' in your configuration.

這是我的smartspace.dao.rdb.RdbActionDao：

    Optional<ActionEntity> readById(String actionKey);

}

這是我的ActionDao：

public interface ActionDao {

    public ActionEntity create(ActionEntity actionEntity);
    public java.util.List<ActionEntity> readAll();  
    public void deleteAll();
}

這是我的Application.java：

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);

    }

EDIT:
After adding the MongoTemplate Bean I have a new error:

Answer 1

我認為mongoTemplate存在依賴性問題。 請在您的dao中添加此代碼。

    @Bean public MongoTemplate mongoTemplate() throws Exception 
{ 
      return new MongoTemplate(mongo(), "database_name");
}

想想這可能有助於mongo（）是你的mongo客戶端。

Answer 2

通過spring.data ....導入正確的庫並使用ID注釋而不是從javax中修復問題。 一。
