}您能添加完整的stacktrace吗？您好，我添加了stacktrace。这不是stacktrace，而是日志。：）在任何情况下，我在你发布的内容中都没有看到任何异常。您好，非常感谢您的帮助，事实上，当我填写表单的所有必填字段并将其提交到postgres数据库时，我在日志中没有发现任何异常。这就是我在这个问题上寻求帮助的原因。我有一个返回码200，如果我查看数据库，没有插入任何数据。是否在类型为“org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder”的
无符合条件的bean后抛出表单错误，异常已修复（类路径中缺少spring安全核心）？
