java - Spring-HTTP Status 500 - 请求处理失败；嵌套异常是 java.lang.IllegalArgumentException : [￞] is not a hexadecimal digit

Question

我正在加密一个巨大的数据文件，并且需要将相同的数据传递给我的“inserData”方法，但是当我将加密数据(user.getEiddata())传递给inserData方法时，我得到-“HTTP状态500 - 请求处理失败；嵌套异常是java.lang.IllegalArgumentException:[￞]不是十六进制数字”当我们转发请求时需要使用什么正确的数据类型？请找到我的以下代码:

回答您的问题

1. 请添加spring-security-core作为 POM.xml 中的依赖项
2. 您应该使用 spring-security-core-4.0.3.RELEASE.jar 中的 PasswordEncoder 接口(interface)来处理您的十六进制数字。

3. 请引用此StandardPasswordEncoder将适合您的情况，也请参阅此 post这将为您提供更多帮助。

4. 这个reference document也会帮助你。
