开启@EnableMongoRepositories注解

/**
* 在启动类或者配置类上添加 @EnableMongoRepositories 注解
* 开启 MongoRepositories, 同时设置扫描的路径, 注意尽可能不要和mybatis和
* mybatis-plus扫描目录重叠,不然可能会被mp代理,致使没法使用.

@Configuration
public class ApplicationConfig {
    
}

javaConfig配置

/**
 * mongoDB配置类
 * 加入@EnableMongoRepositories和@Configuration
 * 继承AbstractMongoConfiguration父类
 */
@Configuration
@EnableMongoRepositories
public class MongoDBConfig extends AbstractMongoConfiguration {

    @Override
    public MongoClient mongoClient() {
        return new MongoClient();
    }

    @Override
    protected String getDatabaseName() {
        return "oss";
    }

    @Override
    protected Collection<String> getMappingBasePackages() {
        return Collections.singletonList( "com" );
