关于mongodb:springboot配置mongodb连接池

application.yml 配置

mongodb:
  address: localhost:27017
  database: soms
  username: admin
  password: 123456
  # 连接池配置
  clientName: soms-task # 客户端的标识，用于定位申请起源等
  connectionTimeoutMs: 10000     # TCP 连贯超时，毫秒
  readTimeoutMs: 15000       # TCP 读取超时，毫秒
  poolMaxWaitTimeMs: 3000        #当连接池无可用连贯时客户端阻塞期待的时长，单位毫秒
  connectionMaxIdleTimeMs: 60000   #TCP 连贯闲置工夫，单位毫秒
  connectionMaxLifeTimeMs: 120000    #TCP 连贯最多能够应用多久，单位毫秒
  heartbeatFrequencyMs: 20000      #心跳检测发送频率，单位毫秒
  minHeartbeatFrequencyMs: 8000    #最小的心跳检测发送频率，单位毫秒
  heartbeatConnectionTimeoutMs: 10000  #心跳检测 TCP 连贯超时，单位毫秒
  heartbeatReadTimeoutMs: 15000    #心跳检测 TCP 连贯读取超时，单位毫秒
  connectionsPerHost: 100       # 每个 host 的 TCP 连接数
  minConnectionsPerHost: 5     #每个 host 的最小 TCP 连接数
 #计算容许多少个线程阻塞期待可用 TCP 连贯时的乘数，算法：threadsAllowedToBlockForConnectionMultiplier*connectionsPerHost，以后配置容许 10*20 个线程阻塞   
  threadsAllowedToBlockForConnectionMultiplier: 10
