Spring引导 - 在类路径资源中定义名为'entityManagerFactory'的bean时出错

我是新来的spring。我目前有这个错误，当我尝试启动。我相信要么缺少一些依赖或我的持久声明。Spring引导 - 在类路径资源中定义名为'entityManagerFactory'的bean时出错

[SpringBoot JPA Hibernate：创建名为'entityManagerFactory'的bean时出错]（https://stackoverflow.com/questions/45530625/springboot -jpa-hibernate-error-creating-bean-with-name-entitymanagerfactory） – pvpkiran

不是，不是重复的，因为所有用户所要做的就是查看原因异常，并且链接的帖子有不同的原因 – DN1

的SQL是

create table leave (id integer not null auto_increment, end_date datetime, 
    is_approved bit not null, remarks varchar(255), start_date datetime, 
    staff_id varchar(255), primary key (id))

你的消息称

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use 
near 'leave (id integer not null auto_increment, end_date datetime, is_approved bit no' at line 1

的原因是，你的表名leave是保留关键字。可悲的是，您的JPA提供商不会自动为您引用关键字，因此您必须指定不同的表名称，或在名称周围标注@Table注释中的引号。或者，或使用自动引用保留关键字的JPA提供程序...

对于你的员工实体你会注意到所有这些生成的类型为long，short或int的id，而不是String类型。如果你想字符串ID，您可以使用UUID的作为ID

@Id 
@GeneratedValue(generator = "uuid") 
@GenericGenerator(name ="uuid", strategy = "uuid2") 
@Column(name = "identification") 
private String identification;
