英文:
Spring boot Data too long for column
问题
我正在使用Spring Boot和MySQL创建用户注册。在设置哈希密码之前，我无法创建新的注册，但在设置密码后却无法正常工作。我尝试了很多方法，但仍然无法解决问题。
错误信息如下：

答案1
得分: 1
你密码的哈希长度大于你数据库中的password列。
从你的领域：
@Column(name="password", length = 20)
private String password;
所以，在你的注解中增加length参数的列长度。
另外，最好重新创建数据库。
英文:
The length of hash of your password is greater than the password column in your DB.
From your domain:
@Column(name="password", length = 20)
private String password;
So, increase the length of your column with parameter length in your annotation.
Also, it is better to re-create the database.
