everyone-java-blog / blog-web / src / main / java / com / zuoxiaolong / blog / web / controller / 路径下的好多方法映射的路径都带“}”，这有什么特殊作用吗？

在执行schema.sql中的创建表语句

CREATE TABLE `java_blog`.`blog_config` (
  `id` INT NOT NULL AUTO_INCREMENT COMMENT '主键',
  `create_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `update_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  `web_user_id` INT NOT NULL COMMENT '用户ID',
  `introduction` VARCHAR(200) NOT NULL DEFAULT '' COMMENT '用户简介',
  `address` VARCHAR(100) NOT NULL COMMENT '用户博客地址',
  PRIMARY KEY (`id`)
)  ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='WEB端用户博客配置表';

会报错：[HY000][1293] Incorrect table definition; there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATE clause

数据库不设外键呀
