测试：

public static void main(String[] args) {
        boolean greaterThan = isGreaterThan("1.1.1", "1.1.2");
        boolean lessThanOrEqual = isLessThanOrEqual("1.1.1", "1.1.2");
        System.out.println("greaterThan :"+greaterThan+",lessThanOrEqual :"+lessThanOrEqual);
    }

测试结果：

greaterThan :false,lessThanOrEqual :true
