java - 如何使用 mongodb 应用程序修复 Spring Boot 中的 UnsatisfiedDependencyException？

Question

我正在尝试将我的 Spring Boot 应用程序数据库从 H2 更改为 MongoDB。我已经更新了 application.properties 文件并删除了所有“@Entity”和“@Column”并添加了“@Document”。我收到的错误是:

Description:

Parameter 0 of constructor in smartspace.dao.rdb.RdbActionDao required a bean named 'mongoTemplate' that could not be found.

Action:

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

After adding the MongoTemplate Bean I have a new error:

Answer 1

我认为 mongoTemplate 存在依赖性问题。请将此代码添加到您的 dao 中。

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

认为这可能会有所帮助，mongo() 是您的 mongo 客户端。
