Spring Boot 無法訪問本地主機 Mongodb

Question

我正在按照這個創建與 Mongo DB 連接的 Spring Boot 應用程序的示例進行操作。 但是，當我運行我的應用程序時，我得到：

Exception in monitor thread while connecting to server localhost:8081

具有以下屬性：

spring.data.mongodb.uri=mongodb://root:example@localhost:8081/test

以及以下MongoClient ：

MongoClient with metadata {"driver": {"name": "mongo-java-driver|sync|spring-boot", "version": "4.8.0"}, "os": {"type": "Linux", "name": "Linux", "architecture": "amd64", "version": "5.15.0-56-generic"}, "platform": "Java/Eclipse Adoptium/17.0.5+8"} created with settings MongoClientSettings{readPreference=primary, writeConcern=WriteConcern{w=null, wTimeout=null ms, journal=null}, retryWrites=true, retryReads=true, readConcern=ReadConcern{level=null}, credential=MongoCredential{mechanism=null, userName='root', source='test', password=<hidden>, mechanismProperties=<hidden>}, streamFactoryFactory=null, commandListeners=[], codecRegistry=ProvidersCodecRegistry{codecProviders=[ValueCodecProvider{}, BsonValueCodecProvider{}, DBRefCodecProvider{}, DBObjectCodecProvider{}, DocumentCodecProvider{}, CollectionCodecProvider{}, IterableCodecProvider{}, MapCodecProvider{}, GeoJsonCodecProvider{}, GridFSFileCodecProvider{}, Jsr310CodecProvider{}, JsonObjectCodecProvider{}, BsonCodecProvider{}, EnumCodecProvider{}, com.mongodb.Jep395RecordCodecProvider@1b9d9a2b]}, clusterSettings={hosts=[localhost:8081], srvServiceName=mongodb, mode=SINGLE, requiredClusterType=UNKNOWN, requiredReplicaSetName='null', serverSelector='null', clusterListeners='[]', serverSelectionTimeout='30000 ms', localThreshold='30000 ms'}, socketSettings=SocketSettings{connectTimeoutMS=10000, readTimeoutMS=0, receiveBufferSize=0, sendBufferSize=0}, heartbeatSocketSettings=SocketSettings{connectTimeoutMS=10000, readTimeoutMS=10000, receiveBufferSize=0, sendBufferSize=0}, connectionPoolSettings=ConnectionPoolSettings{maxSize=100, minSize=0, maxWaitTimeMS=120000, maxConnectionLifeTimeMS=0, maxConnectionIdleTimeMS=0, maintenanceInitialDelayMS=0, maintenanceFrequencyMS=60000, connectionPoolListeners=[], maxConnecting=2}, serverSettings=ServerSettings{heartbeatFrequencyMS=10000, minHeartbeatFrequencyMS=500, serverListeners='[]', serverMonitorListeners='[]'}, sslSettings=SslSettings{enabled=false, invalidHostNameAllowed=false, context=null}, applicationName='null', compressorList=[], uuidRepresentation=JAVA_LEGACY, serverApi=null, autoEncryptionSettings=null, contextProvider=null}

應用程序運行良好，但無法訪問數據庫。 我嘗試了其他幾種設置，例如將localhost替換為127.0.0.1並在單獨的值中聲明設置，以便：

spring.data.mongodb.host=localhost
spring.data.mongodb.port=8081
spring.data.mongodb.database=test
spring.data.mongodb.username=root
spring.data.mongodb.password=example

但似乎沒有任何效果。 Mongo DB 儀表板顯示在localhost:8081 ，因此我知道該數據庫實際上運行良好。

這就是我用來在 Docker 容器中啟動本地 Mongo DB 實例的方式：

# Use root/example as user/password credentials
version: '3.1'

services:

  mongo:
    image: mongo
    restart: always
    environment:
      MONGO_INITDB_DATABASE: test
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example
      ME_CONFIG_MONGODB_URL: mongodb://root:example@mongo:27017/

Answer 1

您在運行 mongo -p 8081:27071嗎？ 我想您的配置- 8081:8081應該更新為“- 8081:27071”。

Answer 2

下載示例代碼

git clone https://github.com/spring-guides/gs-accessing-mongodb-data-rest

轉到 gs-accessing-mongodb-data-rest/complete

在`src/main/下創建目錄resources

創建 application.properties

spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=test
spring.data.mongodb.username=root
spring.data.mongodb.password=example

MongoDB 碼頭工人組成

docker-compose.yml

version: '3.1'

services:

  mongo:
    image: mongo
    restart: always
    ports:
      - 27017:27017
    environment:
      MONGO_INITDB_DATABASE: test
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example
      ME_CONFIG_MONGODB_URL: mongodb://root:example@mongo:27017/

啟動MonogoDB

docker compose up

使用 mongosh

mongosh admin -u root -p example

在蒙哥什

use test

db.createUser({user: "root", pwd: "example", roles: ["dbOwner"]})

exit

運行 Spring Boot

轉到 gs-accessing-mongodb-data-rest/complete

mvn clean spring-boot:run

測試

curl -i -X POST -H "Content-Type:application/json" -d "{  \"firstName\" : \"Frodo\",  \"lastName\" : \"Baggins\" }" http://localhost:8080/people

結果
