我正在尝试将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：
说明：
smartspace.dao.rdb.RdbActionDao中的构造函数的参数0需要找不到名为'mongoTemplate'的bean。
操作：
考虑在您的配置中定义一个名为“ mongoTemplate”的bean。

我认为mongoTemplate存在依赖项问题。请将此代码添加到您的岛中。
@Bean public MongoTemplate mongoTemplate() throws Exception
{
return new MongoTemplate(mongo(), "database_name");
}
认为，这可能对您有所帮助mongo（）是您的mongo客户。

此问题已通过导入正确的库并通过spring.data ....而不是从javax使用ID注释得以解决。一个。
