[英]How to search for a Java string in Eclipse?
I need to search for instances of a character sequence in a Java string using Eclipse. 我需要使用Eclipse在Java字符串中搜索字符序列的实例。 Is there an easy way or regex to do this?
有这么简单的方法或正则表达式吗?
Example: Search for Eggs
should match 示例:搜索
Eggs
应该匹配
String str = "Eggs and toast."
and not match 并不匹配
Eggs e = new Eggs()
File Search
tab File Search
选项卡 Regular expression
radio button Regular expression
单选按钮 ".*?Eggs[^"]*"
in Containing Text
field on top Containing Text
字段中输入文本".*?Eggs[^"]*"
这样的事情对你有用吗?
\".*Eggs.*\"
In general this is very hard because what you want to search for is not "regular" in the sense of "regular expression". 一般来说这很难,因为你想要搜索的内容在“正则表达式”意义上不是“常规”。
One of the answers you've had suggests: 您已经提出的答案之一建议:
\".*Eggs.*\"
which is pretty good, but will still match, for example, 这是相当不错的,但仍然会匹配,例如,
System.out.println("There are " + new Eggs().count() + " eggs");
In general, there is not going to be a regular expression which does exactly what you want. 一般来说,没有一个正则表达式可以完全满足您的需求。
Searching for delimited text using regex is dodgy, however this will basically hit your target (and not too many others): 使用正则表达式搜索分隔文本是狡猾的,但这基本上会击中你的目标(而不是太多其他人):
".*Eggs.*"
Use Search > File > with regex with exactly this search term (ie including the quotes) 使用搜索>文件>与正则表达式完全匹配此搜索词(即包括引号)
This will however also hit lines like this: 然而,这也会像这样:
x = "foo" + new Eggs() + "bar";
Also note that you don't need to delimit the double quote, because it's just a literal as far as regex is concerned 另请注意,您不需要分隔双引号,因为就正则表达式而言,它只是一个字面值
