可以使用如下的Java方法来取出access_token：

public String getAccessToken(String tokenString) {
    String accessToken = "";
    if (tokenString != null && !tokenString.isEmpty()) {
        String[] tokens = tokenString.split(",");
        for (String token : tokens) {
            if (token.contains("access_token=")) {
                accessToken = token.split("=")[1];
                break;
            }
        }
    }
    return accessToken;
}

调用方法如下：

String tokenString = "{access_token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsiV0VCUyJdLCJ1c2VyX2lkIjoiMTY0MzgxNjExMTczMDU2MTAyNiIsInVzZXJfbmFtZSI6InF5dGVzdCIsInNjb3BlIjpbInJlYWQiXSwiZXhwIjoxNzE2MTA3NTU5LCJhdXRob3JpdGllcyI6WyJjdiJdLCJqdGkiOiJiZGE2MmY3OS1lMWM4LTQyYjEtODJlYi0zNWI1OGQ1YTA4OWEiLCJjbGllbnRfaWQiOiJ0ZXN0X2NsaWVudCJ9.19Vf7XxjwlroLWBFuQh0mqeLHnAbQti8Q0c9EveFPyo, token_type=bearer, refresh_token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsiV0VCUyJdLCJ1c2VyX2lkIjoiMTY0MzgxNjExMTczMDU2MTAyNiIsInVzZXJfbmFtZSI6InF5dGVzdCIsInNjb3BlIjpbInJlYWQiXSwiYXRpIjoiYmRhNjJmNzktZTFjOC00MmIxLTgyZWItMzViNThkNWEwODlhIiwiZXhwIjoxNjg1MTExNTU5LCJhdXRob3JpdGllcyI6WyJjdiJdLCJqdGkiOiJmMGQ0NzdlYi05ZGI5LTQ1YTEtYjUyMy01YTljYjY0NzY2ZDUiLCJjbGllbnRfaWQiOiJ0ZXN0X2NsaWVudCJ9.VwOsvGGCb7SWGeIC_X8e7FQyjfbk5LXbgJMHj16ax1c, expires_in=31103999, scope=read, user_id=1643816111730561026, jti=bda62f79-e1c8-42b1-82eb-35b58d5a089a}";
String accessToken = getAccessToken(tokenString);
System.out.println(accessToken);

这个方法会输出：
