jexl中的多个if语句

Question

我一直在尝试想出一个自定义验证，它将检查以下所有三种情况，并根据满足的条件返回错误消息。这两个验证是分开工作的，有没有人可以帮助我们，让系统转到验证2和验证3，然后显示所有消息，而不管之前的条件是否满足

{//VALIDATION1

{ if (this.LastDate < this.occurrence_date) 
{ return "Last Date of Occurrence must be after First Date of Occurrence"; } 

}
}
{//VALIDATION2

{ if (this.FinancialProvision > sysdate) 
{ return "Financial provision date cannot be a future date"; } 

}
}

{//VALIDATION3

{ if (this.Settlement > sysdate) 
{ return "Settlement date cannot be a future date";} 

}
}

Answer 1

为什么不连接验证字符串呢？然后在最后返回连接的字符串。

validation ="";

{//VALIDATION1

{ if (this.LastDate < this.occurrence_date) 
{ validation += " Last Date of Occurrence must be after First Date of Occurrence"; } 

}
}
{//VALIDATION2

{ if (this.FinancialProvision > sysdate) 
{ validation += " Financial provision date cannot be a future date"; } 

}
}

{//VALIDATION3

{ if (this.Settlement > sysdate) 
{ validation += " Settlement date cannot be a future date";} 

}
}
return validation;
