hi trying build junit test case @before setup after processing junit class, found no data changed in database , no exception throws well. funny thing can call controller , can save , delete calling service http client. below code, please help. lot.

@springapplicationconfiguration(classes = mockservletcontext.class) @webappconfiguration public class userrepositorytest extends abstractbestfirsttest {      private mockmvc mvc;      @autowired     private userrepositoryi userrepo;      private void userrepositorytestpreparer() {         user user = new user();         user.setemail("markii@gmail.com");         user.setname("tony stark");         userrepo.deleteall();         userrepo.save(user);     }      @beforetransaction     public void setupdata() {         userrepositorytestpreparer();     }      @before     public void setup() {         mvc = mockmvcbuilders.standalonesetup(new samplecontroller()).build();     }      @after     public void teardown() {         // implement me     }      @transactional     @commit     @test     public void testsave() {         assert.assertequals("save failed", 1, userrepo.finduserbyname("tony stark").size());         assert.assertequals("save failed", 1, userrepo.finduserbyemail("markii@gmail.com").size());     }      @test     public void testrestfulbasic() throws exception {         resultactions actions = mvc.perform(mockmvcrequestbuilders.get("/sample").accept(mediatype.application_json));         actions.andexpect(status().isok());         actions.andexpect(content().string(equalto("hello world! greetings spring boot")));     }  }  @runwith(springjunit4classrunner.class) @springapplicationconfiguration(classes = bestfirstapplication.class) public abstract class abstractbestfirsttest {     protected logger logger = loggerfactory.getlogger(this.getclass());  }  @transactional public interface userrepositoryi extends crudrepository<user, long>,userrepositorycustomerizedi  {   }

i problem solved. in spring test senario, must use platformtransactionmanager process transactions. indeed missed part in db config. after added configuration, problem gone!

@configuration @enabletransactionmanagement public class databaseconfig {      @value("${db.driver}")     private string db_driver;      @value("${db.password}")     private string db_password;      @value("${db.url}")     private string db_url;      @value("${db.username}")     private string db_username;      @value("${hibernate.dialect}")     private string hibernate_dialect;      @value("${hibernate.show_sql}")     private string hibernate_show_sql;      @value("${hibernate.hbm2ddl.auto}")     private string hibernate_hbm2ddl_auto;      @value("${entitymanager.packagestoscan}")     private string entitymanager_packages_to_scan;      @bean     public datasource datasource() {         drivermanagerdatasource datasource = new drivermanagerdatasource();         datasource.setdriverclassname(db_driver);         datasource.seturl(db_url);         datasource.setusername(db_username);         datasource.setpassword(db_password);         return datasource;     }      @bean     public localsessionfactorybean sessionfactory() {         localsessionfactorybean sessionfactorybean = new localsessionfactorybean();         sessionfactorybean.setdatasource(datasource());         sessionfactorybean.setpackagestoscan(entitymanager_packages_to_scan);         properties hibernateproperties = new properties();         hibernateproperties.put("hibernate.dialect", hibernate_dialect);         hibernateproperties.put("hibernate.show_sql", hibernate_show_sql);         hibernateproperties.put("hibernate.hbm2ddl.auto", hibernate_hbm2ddl_auto);         sessionfactorybean.sethibernateproperties(hibernateproperties);          return sessionfactorybean;     }      @bean     public hibernatetransactionmanager transactionmanager() {         hibernatetransactionmanager transactionmanager = new hibernatetransactionmanager();         transactionmanager.setsessionfactory(sessionfactory().getobject());         return transactionmanager;     }      @bean     public platformtransactionmanager transactionmanager(entitymanagerfactory emf) {         jpatransactionmanager transactionmanager = new jpatransactionmanager();         transactionmanager.setentitymanagerfactory(emf);         return transactionmanager;     } }
