   2. 新增 JSON 序列化器 SPI :jackson3,fastjson2
   3. 将 tcc 默认 json 解析器修改为 jackson
   
   
   1. Added JSON whitelist security mechanism
   2. Added JSON serializer SPI : jackson3, fastjson2
   3. Modify the default JSON parser of tcc to jackson
   
   白名单使用方法:
   1. 配置方式
     application.yml:
     seata:
       json:
         allowlist: com.company.model.,com.company.dto.,com.company.UserPo
   
     application.properties:
     seata.json.allowlist=com.company.model.,com.company.dto.,com.company.UserPo
   2. 配置规则
     xxx.  前缀匹配  `com.company.model.` 匹配该包下所有类 
     xxx   精确匹配  `com.company.UserPo` 只匹配这一个类   
   
   How to use the whitelist:
   1. Configuration method: 
   application.yml:
    seata:
      json: 
        allowlist: com.company.model., com.company.dto., com.company.UserPo
   application.properties: 
   
seata.json.allowlist=com.company.model.,com.company.dto.,com.company.UserPo2. 
   2. Configuration rule:
   xxx. Prefix matching `com.company.model.` Matches all classes under this 
package 
   xxx  Exact matching `com.company.UserPo` Only matches this class
