java - Spring + MyBatis exception: Mapped Statements collection does not contain value for -
i got exception when executed app:
public class mainapp { private static applicationcontext context = null; static sqlsession session = null; public static void main(string[] args) throws illegalargumentexception { try { context = new filesystemxmlapplicationcontext( "src/main/webapp/web-inf/applicationcontext.xml"); session = (sqlsession) context.getbean("sqlsession"); ordermapper ordermapper = session.getmapper(ordermapper.class); int orderquantity = ordermapper.getallorder().size(); system.out.println("order quantity: " + orderquantity); session.commit(); session.close(); } catch (throwable e) { e.printstacktrace(); } } } here ordermapper interface:

and 1 more thing, since quite new this, there bad practices in code ? or improve ? please feel free comment, i'd appreciate it.
where have specified mapper xml location? add in sqlsessionfactory's property mapperlocations. since using maven. believe better move mapper xml file folder inside resources directory. when add more number of xml files easier maintain. think below folder structure make sense related stuff grouped jdbc related stuff under 1 package subpackages domain, mappers, service interfaces , service interface implementation.
in case since configurations go inside web-inf/classes directory during compile/packaging, classpath, application configuration should hold good.
