[GitHub] [dubbo] fangxueshun opened a new issue, #10911: 泛化调用时，传入map对象，在消费端反序列化类型错误

fangxueshun opened a new issue, #10911:
URL: https://github.com/apache/dubbo/issues/10911

   
   ### Environment
   
   * Dubbo version: 2.7.15
   * Operating System version: mac,linux
   * Java version: 1.8.0_29
   
   ### Steps to reproduce this issue
   
   1. 客户端发起泛化调用，使用map包装参数，给出
   2. 消费端反序列化时，会提示强转失败
   3. ClassCastException: xxx cannot be cast to xxx
   
   这个问题在版本2.7.0中时不存在的，经过初步定位是因为2.7.15中更新了org.apache.dubbo.common.utils.PojoUtils#realize(java.lang.Object[], java.lang.Class<?>[], java.lang.reflect.Type[])方法的实现导致。
   
   问题复现
   `    public static void main(String[] args) {
           Object[] objects = new Object[1];
           Map<String,Object> map = new HashMap<>();
           map.put("name", "名称");
           map.put("class", TestDemo.class.getName());
           objects[0] = map;
   
           Object[] realize = PojoUtils.realize(objects, new Class[] {TestDemo.class},
                   new Class[] {TestDemo.class});
           System.out.println(realize[0].getClass().getName());
       }`
   
   2.7.15输出：java.util.HashMap
   2.7.0输出：xxx.TestDemo

   > 2.7.15输出：java.util.HashMap
   2.7.0输出：xxx.TestDemo
   
   I tried the example you give above, the results are both `java.util.HashMap`
