Unsatisfied dependency expressed through field 'mongoTemplate'

具体情况是我的聚合项目,在使用

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
           <!– <version>2.1.5.RELEASE</version>–>
        </dependency>

遇到报错,大概就是连接linux 在一段时间,大概8分钟左右,会自动断开,下次第一次刷新会报错,之后就会好了

　自己创建一个demo ,使用的高版本后,并没有此问题,可是老项目中,主依赖中我修改了mongodb的版本,问题依然存在,讲mongodb单纯分出一个项目后,这个问题可以解决.

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
</parent>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

于是只能单独将mongo分出来了,在主项目中引入配置文件

 此时启动会遇到问题:

Unsatisfied dependency expressed through field 'mongoTemplate'

疑惑,测试的demo里面也是这样写的,没有出现此问题,为何迁移到主项目中mongotemplate没有注入

原因:

去掉主项目的启动类中的两个mongoauto配置,就解决了这个问题.
