不是春靴！
请告诉我，如何用“????????”解决问题会话属性的EL“$ {session.userName？：anybody}”的字符（编码问题）？

检查对象内容的编码 - 它是utf-8。首先是过滤顺序，如下面的web.xml文件所示。
veb.hml：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

我找到了问题的根源。
我在TemplateResolver和ViewResolver中添加了一个显式属性name =“characterEncoding”value =“UTF-8”
<bean id="templateResolver"
class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".xhtml" />
<property name="characterEncoding" value="UTF-8" />
<property name="templateMode" value="HTML5" />
<constructor-arg ref="servletContext" />
</bean>
<bean id="templateEngine" class="org.thymeleaf.spring5.SpringTemplateEngine">
<property name="templateResolver" ref="templateResolver" />
</bean>
<bean class="org.thymeleaf.spring5.view.ThymeleafViewResolver">
<property name="templateEngine" ref="templateEngine" />
<property name="order" value="1" />
<property name="characterEncoding" value="UTF-8"/>
<property name="viewNames" value="*" />
</bean>
