spring boot使用spring session，底层数据库mysql实现

1,pom.xml添加依赖：

	
	
            org.springframework.session
            spring-session-jdbc
        

2，application.properties添加配置：

spring.session.store-type=jdbc

3，数据库里创建两张表：

1）

CREATE TABLE `SPRING_SESSION` (
  `SESSION_ID` char(36) NOT NULL DEFAULT '',
  `CREATION_TIME` bigint(20) NOT NULL,
  `LAST_ACCESS_TIME` bigint(20) NOT NULL,
  `MAX_INACTIVE_INTERVAL` int(11) NOT NULL,
  `PRINCIPAL_NAME` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`SESSION_ID`) USING BTREE,
  KEY `SPRING_SESSION_IX1` (`LAST_ACCESS_TIME`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

2）

CREATE TABLE `SPRING_SESSION_ATTRIBUTES` (
  `SESSION_ID` char(36) NOT NULL DEFAULT '',
  `ATTRIBUTE_NAME` varchar(100) NOT NULL DEFAULT '',
  `ATTRIBUTE_BYTES` blob,
  PRIMARY KEY (`SESSION_ID`,`ATTRIBUTE_NAME`),
  KEY `SPRING_SESSION_ATTRIBUTES_IX1` (`SESSION_ID`) USING BTREE,
  CONSTRAINT `SPRING_SESSION_ATTRIBUTES_ibfk_1` FOREIGN KEY (`SESSION_ID`) REFERENCES `SPRING_SESSION` (`SESSION_ID`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
