报错信息："timestamp": "2023-03-27T09:07:50.958+00:00",

• 出错原因：首先看报错信息中这么写到：
  "message": "nested exception is org.apache.ibatis.reflection.ReflectionException: Could not set property 'sicon' of 'class com.pikaqiu.health.bean.SubMenu' with value 'icon-user-list' Cause: org.apache.ibatis.reflection.ReflectionException: There is no setter for property named 'sicon' in 'class com.pikaqiu.health.bean.SubMenu'",
• 这说明多表查询中关系映射写错了，没有与sicon对应的属性，如图
  
  在实体类SubMenu中，sicon(查询时候的别名)存储的名称为icon，把这里改正即可，改成icon
