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*connectionsPerHost,当前配置允许10*20个线程阻塞 threadsAllowedToBlockForConnectionMultiplier:10
用来获取配置参数的类
