springboot配置mongodb连接池的方法步骤

springboot配置mongodb连接池的方法步骤

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，用于定位请求来源等

connectionTimeoutMs: 10000 # TCP连接超时，毫秒

readTimeoutMs: 15000 # TCP读取超时，毫秒

poolMaxWaitTimeMs: 3000 #当连接池无可用连接时客户端阻塞等待的时长，单位毫秒

connectionMaxIdleTimeMs: 60000 #TCP连接闲置时间，单位毫秒

connectionMaxLifeTimeMs: 120000 #TCP连接最多可以使用多久，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连接超时，单位毫秒

heartbeatReadTimeoutMs: 15000 #心跳检测TCP连接读取超时，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

#计算允许多少个线程阻塞等待可用TCP连接时的乘数，算法： threadsAllowedToBlockForConnectionMultiplier*faGSVeVconnectionsPerHost，当前配置允许10*20个线程阻塞

threadsAllowedToBlockForConnectionMultiplier: 10

用来获取配置参faGSVeV数的类
