2016-04-21 04:02hikari数据库连接池问题
spring:
http:
encoding.charset: UTF-8
encoding.enable: true
encoding.force: true
datasource:
name: hikari
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/test
username: root
password: 123456
# hikari
type: com.zaxxer.hikari.HikariDataSource
maximum-pool-size: 100
max-idle: 10
max-wait: 10000
min-idle: 5
initial-size: 5
validation-query: SELECT 1
test-on-borrow: false
test-while-idle: true
time-between-eviction-runs-millis: 18800
第一次启动成功了,没报错,项目也能正常访问了,可是后面更新了项目重新启动之后就一直报错:
org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [HikariDataSource (HikariPool-0)] with key 'dataSource'; nested exception is javax.management.InstanceAlreadyExistsException: com.zaxxer.hikari:name=dataSource,type=HikariDataSource
这是说实例已经存在了吗,这个问题要怎么解决呢
