如何解决如何使用mongoTemplate将Mongo cli命令转换为spring-data-mongo命令以进行mongo聚合
我想使用mongo模板编写以下查询。
$ docker context use remote
Current context is now "remote"
Warning: DOCKER_HOST environment variable overrides the active context. To use "remote",either set the global --context flag,or unset DOCKER_HOST environment variable.
remote
$ docker-compose --context remote build
Define and run multi-container applications with Docker.
Usage:
docker-compose [-f <arg>...] [options] [COMMAND] [ARGS...]
docker-compose -h|--help
Options:
-f,--file FILE Specify an alternate compose file
(default: docker-compose.yml)
-p,--project-name NAME Specify an alternate project name
(default: directory name)
--verbose Show more output
--log-level LEVEL Set log level (DEBUG,INFO,WARNING,ERROR,CRITICAL)
--no-ansi Do not print ANSI control characters
-v,--version Print version and exit
-H,--host HOST Daemon socket to connect to
--tls Use TLS; implied by --tlsverify
--tlscacert CA_PATH Trust certs signed only by this CA
--tlscert CLIENT_CERT_PATH Path to TLS certificate file
--tlskey TLS_KEY_PATH Path to TLS key file
--tlsverify Use TLS and verify the remote
--skip-hostname-check Don't check the daemon's hostname against the
name specified in the client certificate
--project-directory PATH Specify an alternate working directory
(default: the path of the Compose file)
--compatibility If set,Compose will attempt to convert keys
in v3 files to their non-Swarm equivalent
--env-file PATH Specify an alternate environment file
Commands:
build Build or rebuild services
config Validate and view the Compose file
create Create services
down Stop and remove containers,networks,images,and volumes
events Receive real time events from containers
exec Execute a command in a running container
help Get help on a command
images List images
kill Kill containers
logs View output from containers
pause Pause services
port Print the public port for a port binding
ps List containers
pull Pull service images
push Push service images
restart Restart services
rm Remove stopped containers
run Run a one-off command
scale Set number of containers for a service
start Start services
stop Stop services
top Display the running processes
unpause Unpause services
up Create and start containers
version Show the Docker-Compose version information
ERROR: Job failed: exit code 1
我已经尝试了很多,但是没有用。
db.collection.aggregate([
{
$project: {
classes: {
$map: {
input: "$classes",as: "class",in: {
classId: "$$class.classId",students: {
$filter: {
input: "$students",cond: { $in: ["$$this._id","$$class.studentIds"] }
}
}
}
}
}
}
}
])
这没有给出来自mongo shell命令的必需响应。
