Parse a string with key=value pair in a map?

Question

I have below String which is in the format of key1=value1, key2=value2 which I need to load it in a map (Map<String, String>) as key=value so I need to split on comma , and then load cossn as key and 0 its value.

String payload = "cossn=0, itwrqm=200006033213";
Map<String, String> holder =
          Splitter.on(",").trimResults().withKeyValueSeparator("=").split(payload);

I am using Splitter here to do the job for me but for some cases it is failing. For some of my strings, value has some string with equal sign. So for below string it was failing for me:

String payload = "cossn=0, abc=hello/=world";

How can I make it work for above case? For above case key will be abc and value should be hello/=world. Is this possible to do?

You can do this same thing with the Splitter API directly:

Map<String, String> result = Splitter.on(',')
    .trimResults()
    .withKeyValueSeparator(
        Splitter.on('=')
            .limit(2)
            .trimResults())
    .split(input);
