Question

这是我的字符串

“ / opt / jboss-eap / bin / jboss-cli.sh --connect --controller = localhost：9990 -c命令= \“部署/app/jboss-eap-7.1/standalone/updates/sample.war --force \”“

我想按如下方式分割上面的字符串

/opt/jboss-eap/bin/jboss-cli.sh
--connect
--controller=localhost:9990
-c
command="deploy /app/jboss-eap-7.1/standalone/updates/sample.war --force"

我尝试使用以下代码

List<String> matchList = new ArrayList<String>();
Pattern regex = Pattern.compile("[^\\s\"']+|\"[^\"]*\"|'[^']*'");
Matcher regexMatcher = regex.matcher("/opt/jboss-eap/bin/jboss-cli.sh --connect --controller=localhost:9990 -c command=\"deploy /app/jboss-eap-7.1/standalone/updates/sample.war --force\"");
while (regexMatcher.find()) {
    matchList.add(regexMatcher.group());
} 
out.println("matchList="+matchList);

但是输出是

matchList = [/ opt / jboss-eap / bin / jboss-cli.sh，--connect， --controller = localhost：9990，-c，command =，“部署/app/jboss-eap-7.1/standalone/updates/sample.war --force”]

/opt/jboss-eap/bin/jboss-cli.sh
--connect
--controller=localhost:9990
-c
command=
"deploy /app/jboss-eap-7.1/standalone/updates/sample.war --force"

我从此链接Tokenizing a String but ignoring delimiters within quotes使用了另一种方法

String str = "/opt/jboss-eap/bin/jboss-cli.sh --connect --controller=localhost:9990 -c command=\"deploy /app/jboss-eap-7.1/standalone/updates/sample.war --force\"";
String regex = "\"([^\"]*)\"|(\\S+)";
List<String> list = new ArrayList<String>();
Matcher m = Pattern.compile(regex).matcher(str);
while (m.find()) 
{
    if (m.group(1) != null)
    {
        list.add(m.group(1));
    } 
    else 
    {
        list.add(m.group(2));
    }
}
out.println(list);

输出为

/opt/jboss-eap/bin/jboss-cli.sh
--connect
--controller=localhost:9990
-c
command="deploy
/app/jboss-eap-7.1/standalone/updates/sample.war
--force"

只需使用带有多个定界符的String split＃method。

String string = "/opt/jboss-eap/bin/jboss-cli.sh --connect --controller=localhost:9990 -c command=\"deploy /app/jboss-eap-7.1/standalone/updates/sample.war --force\";
String[] parts = string.split("((-c)|(\\--))");
String part1 = parts[0]; 
String part2 = parts[1];

以此类推。这样，您还将分隔符保留在字符串部分中。
