spring - java.lang.ExceptionInInitializerError at UserDaoImpl.<clinit>(UserDaoImpl.java:71) -


it's testhelper:

  @runwith(springjunit4classrunner.class)     @contextconfiguration(locations = { "classpath*:web-inf/spring/appservlet/servlet-context.xml" })      public class testhelper {          @mock         private userdaoimpl userdaoimpl;         @injectmocks         private helper helper=new helper();          private mockmvc mockmvc;         string msg = "success";         int status = 200;         responsemessage message = new responsemessage();          @before         public void setup() {             mockitoannotations.initmocks(this);             this.mockmvc = mockmvcbuilders.standalonesetup(helper).build();         }          @test             public void testcategories() throws exception {             message = helper.getcategories(0);             assertnotnull(message);             assert.assertequals(status, message.getstatus());             assert.assertequals(msg, message.getmessage());         }   }

it's helper class:

public class helper extends basehelper {      @autowired     private userdao userdao;     private static final logger logger = loggerfactory             .getlogger(helper.class);      public responsemessage getcategories(int categoryid) {         logger.info("**helper getcategories() entry*****");         responsemessage message;         try {             list<category> categories = userdao                     .getcategories(categoryid);             string jsonconverted = utility                     .converttojsonstring(categories);             com.fasterxml.jackson.databind.objectmapper mapper = new com.fasterxml.jackson.databind.objectmapper();             object obj = mapper                     .readvalue(                             jsonconverted,                             new typereference<list<category>>() {                             });             message = prepareresponse(obj, 200, "success");         } catch (exception e) {             logger.error("****exception in helper getcategories() : "                     + e.getstacktrace());              message = prepareresponse( null, 500,                     e.getmessage());          }         logger.info("***helper getcategories() exit****");         return message;     } }

it's userdaoimpl class:

public class userdaoimpl implements userdao {      private static properties applicationproperties;      static {         applicationproperties = utility.loadappproperties();     }     public list<category> getcategories(int category_id) {         session session = null;         list<category> categories = null;         try {             session = sessionfactory.getcurrentsession();             logger.info("enter getcategories  method's body");             transaction tx = session.begintransaction();             if (!utility.iszeroint(category_id)) {                 list list = session.createcriteria(category.class).add(restrictions.eq("category_id", category_id))                         .setresulttransformer(criteria.distinct_root_entity).list();                 categories = list;             } else {                 list list = session.createcriteria(category.class).setresulttransformer(criteria.distinct_root_entity)                         .list();                 categories = list;             }             tx.commit();         } catch (exception e) {             throw new dataexception("unable categories. please try after time.");         }         logger.info("exit getcategories method's body");         return categories;     } }

when test helper class got error on applicationproperties = utility.loadappproperties(); in userdaoimpl class. , error java.lang.exceptionininitializererror. error generate @ time of load property file in userdaoimpl class.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
