Question

我试图在groovy中替换一个大字符串。但无法让它发挥作用。我正在使用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

如果我更换一个较短的字符串，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

尝试这种模式：

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

你需要记住逃避特殊字符 - 例如? - ＆gt; \?

所以，总结一下，它结束为：

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"

关于主题：在用任何其他语言替换字符串，groovy，Java和（我希望！）时，字符串长度无关紧要。重要的是，在更大的模式中，更容易省略会导致不匹配的内容。所以你应该使用简单易懂的代码阅读器模式。

例如：

http:\/\/.* - 匹配以http://

开头的每个字符串
