gavenpeng opened a new pull request, #18317:
URL: https://github.com/apache/shardingsphere/pull/18317

   Increment feature:
   
   Changes proposed in this pull request:
   - 1 对强制路由做了增强，不需要规则配置为Hint模式，只要线程上下文带有强制路由的标志，就可以路由到指定的库和表，
   不受分表规则的影响.
   - 2 使用demo：
   ```
   public void demoFunc() {
       // 实例化HintManager
       HintManager hintManager = HintManager.getInstance();
       // 强制路由到哪个分库，具体的分库名见paas平台上的分片配置，一般是：ds_0，ds_1这种
       hintManager.addDatabaseShardingValue("logic_database_name(请填写你的逻辑库名)", "databaseName_name(请填写你的真实库名)");
       // 强制路由到哪个真实表
       hintManager.addTableShardingValue("logic_table_name(请填写你的逻辑表名)", "real_table_name(请填写你的真实表名)");
       try {     // java7之后，也可以使用try-with-resource写法！！
           xxxxxxx   // 业务逻辑
       } catch (Throwable e) {
           xxxxxxx   // 业务逻辑
       } finally {
           // 必须要写，不能少，切记，切记！！！！否则后面都会出错
           hintManager.close();   
       }
   }
   ```
