尝试对mysql数据库运行insert语句时发生错误。我已经为hibernate打开了sql args跟踪，以确切地查看操作转换为查询以及绑定的内容。
在mysql数据库中，列ATTRIBUTE_NAME是VARCHAR（200）...查看跟踪的日志，我看到字符串是79个字符（“org.springframework.security.web.csrf.HttpSessionCsrfTokenRepository.CSRF_TOKEN”）。
下面是日志-请给我指出正确的方向，因为这确实让我很困惑。查找“SQL错误：1406，SQLState：22001”并在此之前读取条目。

The attr: org.springframework.security.web.csrf.HttpSessionCsrfTokenRepository.CSRF_TOKEN
 and the length: 79
The attr: SPRING_SECURITY_CONTEXT
 and the length: 23

我肯定漏掉了什么明显的东西。

上面的代码在mysql workbench中运行时会显示一个警告，并将ATTRIBUTE_NAME截断为'org.springframework.security.web.csrf.HttpSessionC'
如果我跑步：

insert into CODE_NAME_SESSION_ATTRIBUTE (ATTRIBUTE_NAME, ATTRIBUTE_VALUE, CODE_NAME_SESSION_ID) 
values 
(
    'CSRF_TOKEN'
    , _binary'..\0.sr\06org.springframework.security.web.csrf.DefaultCsrfTokenZ.../....\0.L\0\nheaderNamet\0.Ljava/lang/String;L\0\rparameterNameq\0~\0.L\0.tokenq\0~\0.xpt\0.X-CSRF-TOKENt\0._csrft\0$04735f03-57cf-4984-860c-e8e03400d432'
    , 474);

在没有警告的情况下工作，显示表没有为ATTRIBUTE_NAME占用更长的长度。我觉得现在这是一个MySQL的问题，而不是Java + Spring + JPA
