java - Resultset getString throw ArrayIndexOutOfBoundsException -
i got exception when trying retrieve string value resultset. happens after added 2 new columns image_url , icon_url table (default null) , trying retrieve new added columns. table create statement below:
create table `examples` ( `id` int(11) not null auto_increment, `name` varchar(255) collate utf8_unicode_ci default null, `description` text collate utf8_unicode_ci, `event_id` int(11) default null, `created_at` datetime not null, `updated_at` datetime not null, `session_id` varchar(255) collate utf8_unicode_ci default null, `location` varchar(255) collate utf8_unicode_ci default null, `start_date` datetime default null, `end_date` datetime default null, `url` varchar(255) collate utf8_unicode_ci default null, `button_label` varchar(255) collate utf8_unicode_ci default null, `hidden` tinyint(1) default null, `image_url` varchar(255) collate utf8_unicode_ci default null, `icon_url` varchar(255) collate utf8_unicode_ci default null, primary key (`id`) ) engine=innodb auto_increment=427 default charset=utf8 collate=utf8_unicode_ci; the query pretty simple, query fields examples object:
@override public list<example> getexamples(integer eventid) { return jdbctemplate.query( "select * examples event_id= ?", new object[]{eventid}, (rs, rownum) -> { example ex = new example(); ex.setid(rs.getint("id")); ex.setname(rs.getstring("name")); ex.setdescription(rs.getstring("description")); ex.setexpoid(rs.getint("expo_id")); ex.setsessionid(rs.getstring("session_id")); ex.setlocation(rs.getstring("location")); ex.setstartdate(rs.getstring("start_date")); ex.setenddate(rs.getstring("end_date")); ex.seturl(rs.getstring("url")); ex.setbuttonlabel(rs.getstring("button_label")); ex.sethidden(rs.getboolean("hidden")); ex.setimageurl(rs.getstring("image_url")); //throw arrayindexoutofboundsexception ex.seticonurl(rs.getstring("icon_url")); // throw arrayindexoutofboundsexception }); } the exception go away if update image_url , icon_url empty string instead of null value.
i'm using hikaricp config , manage datasouce:
@bean(name = "datasouce") public datasource datasouce() { hikariconfig config = new hikariconfig(); config.setjdbcurl(env.getproperty("ds.url")); config.setusername(env.getproperty("ds.username")); config.setpassword(env.getproperty("ds.password")); config.setdriverclassname(env.getproperty("ds.driver.classname")); config.adddatasourceproperty("cacheprepstmts", "true"); config.adddatasourceproperty("prepstmtcachesize", "250"); config.adddatasourceproperty("useserverprepstmts", "true"); config.adddatasourceproperty("uselocalsessionstate", "true"); config.adddatasourceproperty("uselocaltransactionstate", "true"); config.adddatasourceproperty("rewritebatchedstatements", "true"); config.adddatasourceproperty("cacheresultsetmetadata", "false"); config.adddatasourceproperty("cacheserverconfiguration", "true"); config.adddatasourceproperty("elidesetautocommits", "true"); config.adddatasourceproperty("maintaintimestats", "false"); return new hikaridatasource(config); } i've been debugging hours no luck of finding what's going on, pretty new hikaricp not sure if have effect caching query results. complete exception trace below:

an arrayindexoutofboundsexception thrown when server-side prepared statement used , there null in blob, text, or json type column in resultset
this fixed in connector / j 8.0.7
an arrayindexoutofboundsexception thrown when server-side prepared statement used , there null in blob, text, or json type column in resultset. (bug #25215008, bug #84084)
