java - 字符串正斜杠被替换

Question

我有以下代码

String outputStr = "-XX:-HeapDumpOnOutOfMemoryError -XX:MaxPermSize=64m -Xms24m -Dcom.sun.management.jmxremote.password.file=\"E:Java\\jmx-management\\jmxremote.password\" -Djava.awt.headless=true";

outputStr.replaceAll("-Dcom.sun.management.jmxremote.password.file=[\"\\w\\=\\.\\!\\#\\$\\%\\&\\*\\+\\-\\~\\:\\;\\,\\@\\|\\\\\\/]+",
    "-Dcom.sun.management.jmxremote.password.file=\"E:\\Java\\jmx-management\\jmxremote.password\"");

它给了我

-XX:-HeapDumpOnOutOfMemoryError -XX:MaxPermSize=64m -Xms24m -Dcom.sun.management.jmxremote.password.file="E:Javajmx-managementjmxremote.password" -Djava.awt.headless=true

我想要这个

-XX:-HeapDumpOnOutOfMemoryError -XX:MaxPermSize=64m -Xms24m -Dcom.sun.management.jmxremote.password.file="E:\Java\jmx-management\jmxremote.password" -Djava.awt.headless=true

在替换中不进行更改

"-Dcom.sun.management.jmxremote.password.file=\"E:\\Java\\jmx-management\\jmxremote.password\""

outputStr = outputStr.replace("\\\\", "\\");
