利用redis解决:
默认已安装redis
引入jar包
compile group: 'org.springframework.session', name: 'spring-session-data-redis', version: '1.3.1.RELEASE'// https://mvnrepository.com/artifact/biz.paluch.redis/lettuce compile group: 'biz.paluch.redis', name: 'lettuce', version: '4.4.2.Final'
redis.properties
redis_hostName = localhost redis_port = 6379 redis_password = redis_timeout = 3600 redis.maxIdle=300 redis.maxActive=600 redis.maxWait=1000 redis.testOnBorrow=truespring.xml
