spring-security 使用html代码和spring boot的spring Boot 注册错误,我无法继续注册过程后，点击提交我得到了这个错误

这是单击注册页面上的“提交”按钮后出现的错误消息

发生意外错误（类型=内部服务器错误，状态=500）。rawPassword不能为空值
第一个
这是登录页面的html代码。我没有做这个，我只是在互联网上找到它，并试图改变它，这样它就可以匹配我的用户实体，但我认为错误在这里，但我不能找到它通常的thobject，所以它匹配我的enity，我也修改了thfield，但正如我所说，我不知道要改变什么。我是一个html新手tho。

根据您的错误堆栈跟踪

java.lang.IllegalArgumentException: rawPassword cannot be null
    at org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder.encode(BCryptPasswordEncoder.java:107)

它只是意味着您传递给bCryptPasswordEncoder.encode(password)的密码变量为空。

Utilisateur.setPasswordUtl(bCryptPasswordEncoder.encode(password));

并且在您的表单从前端提交后它将为空的唯一原因是

*您尚未将html属性与模型属性正确Map。

并且将null传递给编码器并引发错误。

根据以下建议更正您的thymleaf html模板。

更改下面的html以正确MapModelAttribute中的详细信息。

<div class="form-group">
    <label for="password">Password</label>
    <input type="password" class="form-control form-control-lg" required placeholder="Password"
                       name="passwordUtl"
                       id="password">
</div>

您正在将html标记定义为name="password"，而它应该按照您在实体类name="passwordUtl"中定义的属性。
您的实体类具有不同的命名变量，并且您在html中使用了不同的名称。
根据您的实体类属性名称，按照上面的建议更正所有其他html names。
