EqualsIgnoreCase在流口水上 [英] EqualsIgnoreCase on Drools

问题描述

我正在尝试使用正则表达式将drl重写为equalsIgnoreCase，因为我认为它更快.我不知道它的速度如何.但是，由于某些原因，流口水不喜欢它，并且出现未知错误.

I am trying to rewrite my drl from using regex to equalsIgnoreCase as I think its faster. I am not sure its faster though. However, drools doesn't like it for some reason and I get unknown error.

最上面的那个有效，但是使用equalsIgnoreCase的那个不起作用

The one on top works, but the one using equalsIgnoreCase doesn't

rule "name"
salience 0
activation-group "flow"
dialect "mvel"
no-loop true
when
    $vurderinger: Vurderinger(vurdering1909 != null &&
                              vurdering1909.verdi matches "(?i)^FOO$")
then
    modify( $vurderinger ) { setVurdering1913(new DroolsType("SHOW")) }
end


rule "name"
salience 0
activation-group "flow"
dialect "mvel"
no-loop true
when
    $vurderinger: Vurderinger(vurdering1909 != null &&
                 eval("FOO".equalsIgnoreCase(vurdering1909.verdi)))
then
    modify( $vurderinger ) { setVurdering1913(new DroolsType("SHOW")) }
end

有人能发现错误吗?

推荐答案

在eval内，请坚持使用Java:引用绑定变量，请使用getter.

Within eval, stick to Java: refer to bound variables, use getter.

when
$vurderinger: Vurderinger($v: vurdering1909 != null &&
             eval("FOO".equalsIgnoreCase($v.getVerdi())))
then

编辑我不知道类定义，错误和版本，我建议使用eval/Java来保证安全，无论Drools版本是什么.对于6.3.0，您可以省略eval，它可以正常工作.

Edit Not knowing the class definition, the error and the version, I advise using eval/Java, to be on the safe side, no matter what the Drools version is. For 6.3.0, you can omit eval, and it works.

when
$vurderinger: Vurderinger(vurdering1909 != null &&
              "FOO".equalsIgnoreCase(vurdering1909.verdi))
then
