## Bug Report Caused by: java.lang.IllegalArgumentException: argument type mismatch **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/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 anymore 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? 5.4.0 ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-JDBC ### Expected behavior following of method always is returned ，but occasionally following of method is returned ： public void setDbType(String dbType) { this.dbTypeName = dbType; } ### Actual behavior sometime following of method is returned ： public void setDbType(DbType dbType) { if (dbType == null) { this.dbTypeName = null; } else { this.dbTypeName = dbType.name(); } } ### Reason analyze (If you can) when datasource is DruidDataSource，paramter type is not considered。 original method： private Optional<Method> findSetterMethod(final String fieldName,) { return Arrays.stream(dataSourceMethods).filter(each -> each.getName().equals(setterMethodName) && 1 == each.getParameterTypes().length).findFirst(); } modified method： private Optional<Method> findSetterMethod(final String fieldName, final Object fieldValue) { String setterMethodName = SETTER_PREFIX + CaseFormat.LOWER_CAMEL.to(CaseFormat.UPPER_CAMEL, fieldName); // TODO 这里下面改了 return Arrays.stream(dataSourceMethods).filter(each -> each.getName().equals(setterMethodName) && 1 == each.getParameterTypes().length && each.getParameterTypes()[0]==fieldValue.getClass()).findFirst(); // TODO 这里上面改了 // TODO 这里下面原来的代码 // return Arrays.stream(dataSourceMethods).filter(each -> each.getName().equals(setterMethodName) && 1 == each.getParameterTypes().length).findFirst(); // TODO 这里上面原来的代码 } ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. ### Example codes for reproduce this issue (such as a github link). -- This is an automated message from the Apache Git Service.
