komawei opened a new issue #2707: Java Configuration example compile failure, field "column" no setter of class KeyGeneratorConfiguration URL: https://github.com/apache/incubator-shardingsphere/issues/2707 ## Bug Report **For English only**, other languages will not accept. Before report a bug, make sure you have: - Searched open and closed [GitHub issues](https://github.com/apache/incubator-shardingsphere/issues). - Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview). Please pay attention on issues you submitted, because we maybe need more details. If no response **more than 7 days** and we cannot reproduce it on current information, we will **close it**. Please answer these questions before submitting your issue. Thanks! ### Which version of ShardingSphere did you use? 4.0.0.RC-1 ### Which project did you use? Sharding-JDBC or Sharding-Proxy? Sharding-JDBC ### Expected behavior Compile success ### Actual behavior Compile failure. ### Reason analyze (If you can) 1. According to Java Configuration example below, [Java Configuration](https://shardingsphere.apache.org/document/current/cn/manual/sharding-jdbc/configuration/config-java/) ``` private static KeyGeneratorConfiguration getKeyGeneratorConfiguration() { KeyGeneratorConfiguration result = new KeyGeneratorConfiguration(); result.setColumn("order_id"); return result; } ``` the compilation is failed, cause KeyGeneratorConfiguration doesn't have the "column" setter at ver 4.0.0-RC1, and KeyGeneratorConfiguration doesn't have default constructor. 2. method signature of ShardingDataSourceFactory@createDataSource not match Java Configuration example. example: return ShardingDataSourceFactory.createDataSource(createDataSourceMap(), shardingRuleConfig); acutal: ``` public static DataSource createDataSource(Map<String, DataSource> dataSourceMap, ShardingRuleConfiguration shardingRuleConfig, Properties props) throws SQLException { return new ShardingDataSource(dataSourceMap, new ShardingRule(shardingRuleConfig, dataSourceMap.keySet()), props); } ``` 3. TableRuleConfiguration does not have default constructor. maybe some other classes have the same bug. ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. just copy codes into IDE. ### Example codes for reproduce this issue (such as a github link).
