正则表达式将字符串中的文件路径替换为Java中的其他文件路径

我有一个字符串形式的文本文件'str'

 # Configuration file for the Jakarta ISAPI Redirector

# The path to the ISAPI Redirector Extension, relative to the website
# This must be in a virtual directory with execute privileges
extension_uri=/jakarta/isapi_redirect.dll

# Full path to the log file for the ISAPI Redirector
log_file=C:\\\\Programs\\\\Org\\\\Pro\\\\Client\\\\apache-tomcat-8.0.33\\\\logs\\\\isapi_redirect.log

# Log level (debug, info, warn, error or trace)
log_level=info

# Full path to the workers.properties file
worker_file=C:\\\\Programs\\\\Org\\\\Pro\\\\Client\\\\apache-tomcat-8.0.33\\\\conf\\\\workers.properties

# Full path to the uriworkermap.properties file
worker_mount_file=C:\\\\Programs\\\\Org\\\\Pro\\\\Client\\\\apache-tomcat-8.0.33\\\\conf\\\\uriworkermap.properties

我想替换所有出现的

C:\\\\Programs\\\\Org\\\\Pro\\\\Client\\\\apache-tomcat-8.0.33 

与

因此，我的最后一个'str'如下所示

# Configuration file for the Jakarta ISAPI Redirector

# The path to the ISAPI Redirector Extension, relative to the website
# This must be in a virtual directory with execute privileges
extension_uri=/jakarta/isapi_redirect.dll

# Full path to the log file for the ISAPI Redirector
log_file=C:\\\\Program Files\\\\Apache Software Foundation\\\\Tomcat 9.0\\\\logs\\\\isapi_redirect.log

# Log level (debug, info, warn, error or trace)
log_level=info

# Full path to the workers.properties file
worker_file=C:\\\\Program Files\\\\Apache Software Foundation\\\\Tomcat 9.0\\\\conf\\\\workers.properties

# Full path to the uriworkermap.properties file
worker_mount_file=C:\\\\Program Files\\\\Apache Software Foundation\\\\Tomcat 9.0\\\\conf\\\\uriworkermap.properties

基本上，我想在遇到“apache”之前替换“=”之后的filepath。这个“apache”有时也可以是“Tomcat”

我访问了stackoverflow中几乎所有的答案/解决方案，并试图对它们进行调整，但没有一个能产生预期的输出

我尝试了大约8-9个正则表达式，因为太多了，我没有发布它们。

“\”是正则表达式中的一个元字符，这意味着你应该编码

“\\\”

，同时“需要在Java中转义，这样如果你想匹配“\”字符，你应该编码

“\\\\”

您不需要正则表达式，只需执行

str=str.replace（“C:\\\\Programs\\\\Org\\\\Pro\\\\Client\\\\apache-tomcat-8.0.33”，“C:\\\\\Program Files\\\\\apache Software Foundation\\\\\tomcat 9.0”）

您收到的不想要的结果是什么？你在用什么代码？@Titus基本上我想在“=”之后替换filepath，直到遇到“apache”，这个apache有时可能是“Tomcat”well@shash678有一个

模式。LITERAL

从参数中转义所有特殊字符，它使用正则表达式，但不将参数解释为正则表达式。@SHSH678是的，

replace

方法使用正则表达式引擎，但由于

Pattern.LITERAL

的原因，它不“支持”正则表达式语法。
