java - 替换groovy中的大字符串

Question

我正在尝试替换 groovy 中的一个大字符串。但无法让它发挥作用。我使用的是 groovy 1.8.6

def textn = "http://10.33.0.69:8001/VS_SiteFacilityLookup/SiteFacilityLookupService?XSD=/com/enbridge/csim/ebo/module/common/serviceinterface/SiteFacilityLookupService.xsd"
textn = textn.replaceAll("http://10.33.0.69:8001/VS_SiteFacilityLookup/SiteFacilityLookupService?XSD=/com/enbridge/csim/ebo/module/common/serviceinterface/SiteFacilityLookupService.xsd", "hola")
println "textn : $textn"

这会打印出原始变量

如果我替换较短的字符串，它会正确替换它。

def textn = "http://10.33.0.69:8001/VS_SiteFacilityLookup/SiteFacilityLookupService?XSD=/com/enbridge/csim/ebo/module/common/serviceinterface/SiteFacilityLookupService.xsd"
textn = textn.replaceAll("SiteFacilityLookupService.xsd", "hola")
println "textn : $textn"

这会打印出预期的结果

尝试这个模式:

http:\/\/10.33.0.69:8001\/VS_SiteFacilityLookup\/SiteFacilityLookupService\?XSD=\/com\/enbridge\/csim\/ebo\/module\/common\/serviceinterface\/SiteFacilityLookupService.xsd

您需要记住转义特殊字符 - 例如? -> \?

所以，总结一下，结果是:

def textn = "http://10.33.0.69:8001/VS_SiteFacilityLookup/SiteFacilityLookupService?XSD=/com/enbridge/csim/ebo/module/common/serviceinterface/SiteFacilityLookupService.xsd"
textn = textn.replaceAll("http:\/\/10.33.0.69:8001\/VS_SiteFacilityLookup\/SiteFacilityLookupService\?XSD=\/com\/enbridge\/csim\/ebo\/module\/common\/serviceinterface\/SiteFacilityLookupService.xsd", "hola")
println "textn : $textn"

主题:在 groovy、Java 和(我希望!)任何其他语言中替换字符串时，字符串长度并不重要。重要的是，在较大的模式中，更容易省略一些导致不匹配的内容。因此，您应该使用简单且易于代码读者理解的模式。

例如:

http:\/\/.* - 匹配以 http://

开头的每个字符串
