jimmycheng888 opened a new issue #2302: ShardingPreparedStatement Class exception not caught
URL: https://github.com/apache/incubator-shardingsphere/issues/2302
 
 
   **Which version of ShardingSphere did you use?**
   3.1.0
   
   **Which project did you use? Sharding-JDBC or Sharding-Proxy?**
   Sharding-JDBC
   
   `Actual behavior`
   The code exception is not caught, causing a null pointer exception, and does not throw a true exception, making it impossible for the developer to accurately determine what went wrong.
   
   **Example codes for reproduce this issue (such as a github link).**
   The code  packge is : io.shardingsphere.shardingjdbc.jdbc.core.statement
   
   For example, the following code, the special symbol will be a direct null pointer, and the real reason is not exposed.
   
      ```
    @Override
       public boolean execute() throws SQLException {
           try {
               clearPrevious();
               sqlRoute();
               initPreparedStatementExecutor();
               return preparedStatementExecutor.execute();
           } finally {
               refreshTableMetaData(connection.getShardingContext(), routeResult.getSqlStatement());
               clearBatch();
           }
       }
   ```
