Java 错误：用户没有'；使用spring security时，不能使用此用户名存在

我正在使用SpringBoot+SpringSecurity构建后端，并用Postman进行测试。 对于前端，我将使用Android应用程序

实现了http基本身份验证

当我单击Postman中的Authentication选项卡并从下拉框中选择Basic Auth，然后在其中输入用户名和密码字段时，它就可以正常工作了。但当我发送原始JSON请求正文时，我得到以下错误：

org.springframework.security.authentication.InternalAuthenticationServiceException:不存在具有此用户名的用户：

我想这是由这个班级引起的

公共集合如果使用“邮递员授权”选项卡，邮递员将构造相应的授权标头
Authorization:Basic
，其中
credentials
是用户名和密码的Base64编码

您可以在邮递员请求中看到此标题，单击标题并隐藏

Spring Security HTTP basic authentication需要此标头。如果您只是在请求正文中以JSON形式发布用户名和密码，Spring Security HTTP basic authentication无法从标头中提取用户名。因此，
user
等于
null
，并引发异常。
HI
header->Basic ZG9tZTpkb21lZG9tZTM1
。请查看我的问题更新，我也发布了图片。我需要做什么才能让它工作？从header中提取用户名？@user9347049你写的，但我不确定为什么，因为它与Postman auth下拉框一起工作。所以它工作了。无需再做任何事情。
用户存储库。findByUsernameAndPassword
 不起作用。使用纯文本密码和用户名查找带有编码pwd的用户当然不起作用。它还绕过了Spring Security。所以不要这样做。还要确保用户确实存在。您不应该发送JSON，因为您使用的是基本身份验证，Spring Security将处理身份验证部分。您正在使用没有端点的基本身份验证。只需发送授权标头。例如，您的邮递员已经在发送标头。如果您有表单，为什么要使用基本身份验证。。。
