请问如何解决 谢谢

您是否在某项配置中将实体生命值设置为了"541959.0"？
若是，请将其修改为0~20之间的一个值；

以上

java.lang.IllegalArgumentException: Health must be between 0 and 20.0(541959.0)   由此可知你的health数值过高了 你打开服务端里面的spigot.yml 找到以下配置：

把max改改就行了

这块很早就改过了....
  attribute:
    maxHealth:
      max: 10000000000000000000
    movementSpeed:
      max: 9.999999999E9
    attackDamage:
      max: 10000000000000000000
