问题
Is there a general Scala utility method that converts a string to a string literal? The simple lambda function "\"" + _ + "\"" only works for strings without any special characters.
For example, the string \" (length 2) should be converted to the string "\\\"" (length 6).

Have a look at Apache Common's StringEscapeUtils class (docs here). escapeJava should get the job done.
Have a look at this example to see it in action (in Java).
回答2:
Wrap the String with 3 quotes to represent it as is..
e.g.
val str = """ \" """ // str : java.lang.String = \"
