In Java, is there a way to write a string literal without having to escape quotes?可能的重复:在Java中，是否有一种方法可以在不需要转义引号的情况下写入字符串文字?
private static final String CREATE_TABLE_EXHIBITORS = "CREATE TABLE "users" ("_id" text PRIMARY KEY ,"name" text,"body" text,"image" text,"stand_id" text,"begin" long,"end" long,"changedate" long,"website" text,"facebook" text,"myspace" text,"twitter" text,"festivallink" text,"favorite" integer);";
Let's say I want this query to be a valid string in Java. Do I have to convert it to escape all double quotes with a trailing slash in front?
假设我希望这个查询在Java中是一个有效的字符串。我是否必须转换它来转义所有的双引号并在前面加上斜杠?
e.g. = "CREATE TABLE \"users"\
Or is there a faster way to make this whole query a valid string at once? I thought you could use single quotes around the whole string to do that but that doesn't work either.
或者是否有更快的方法使整个查询成为有效的字符串?我认为你可以在整个字符串中使用单引号，但这也不行。

Escaping the double quotes with backslashes is the only way to do this in Java.
用反斜杠转义双引号是在Java中实现这一点的唯一方法。
Some IDEs around such as IntelliJ IDEA do this escaping automatically when pasting such a String into a String literal (i.e. between the double quotes surrounding a java String literal)
一些ide，比如IntelliJ IDEA，在将一个字符串粘贴到一个字符串文字时自动转义(例如在java字符串文字周围的双引号之间)
One other option would be to put the String into some kind of text file that you would then read at runtime
另一个选项是将字符串放入某种文本文件中，然后在运行时读取

Use Java's replaceAll(String regex, String replacement)
使用Java的replaceAll(字符串regex，字符串替换)
For example, Use a substitution char for the quotes and then replace that char with \"
例如，对引号使用替换字符，然后用\"替换该字符
String newstring = String.replaceAll("%","\"");
or replace all instances of \" with \\\"
或用“只\只\只\”替换所有的“只\只\只\只\只\”
String newstring = String.replaceAll("\"","\\\"");

For a String constant you have no choice other than escaping via backslash.
对于字符串常量，除了通过反斜线转义之外，您别无选择。
Maybe you find the MyBatis project interesting. It is a thin layer over JDBC where you can externalize your SQL queries in XML configuration files without the need to escape double quotes.
也许你觉得MyBatis项目很有意思。它是JDBC上的一层很薄的层，您可以在XML配置文件中具体化SQL查询，而不需要转义双引号。

Yes you will have to escape all double quotes by a backslash.
是的，你将不得不通过反斜杠来逃避所有双引号。
