java - Spring jpa - can't use more than one EntityManagerFactory -

i'm working on java spring mvc application uses hibernate , jpa persistence layer. have 2 databases , want map entity tables in database1 , in database2. have defined 2 configuration classes this:

first:

@configuration @enabletransactionmanagement @enablejparepositories(value = "com.mycompany.project.persistence.orm.module.common",entitymanagerfactoryref = "commonentitymanagerfactory",transactionmanagerref = "commontransactionmanager") public class persistenceconfigcommon {      public persistenceconfigcommon() {     }       properties additionalproperties() {         return new properties() {             {                   setproperty("hibernate.dialect", "org.hibernate.dialect.mysqldialect");                 setproperty("hibernate.hbm2ddl.auto", "update");                 setproperty("hibernate.show_sql", "true");                 setproperty("hibernate.enable_lazy_load_no_trans", "true");                 setproperty("hibernate.connection.charset", "utf8");                 setproperty("hibernate.connection.characterencoding", "utf8");                 setproperty("hibernate.connection.useunicode", "true");             }         };     }      @primary     @bean(name = "commonentitymanagerfactory")     public entitymanagerfactory commonentitymanagerfactory() {entitymanagerfactorybean");         localcontainerentitymanagerfactorybean factory = new localcontainerentitymanagerfactorybean();         factory.setpersistenceunitname("common");         factory.setdatasource(commondatasource());         factory.setpackagestoscan("com.mycompany.project.persistence.orm.module");          hibernatejpavendoradapter vendoradapter = new hibernatejpavendoradapter();         vendoradapter.setgenerateddl(boolean.true);         vendoradapter.setshowsql(boolean.true);         factory.setjpavendoradapter(vendoradapter);         factory.setjpaproperties(additionalproperties());          factory.afterpropertiesset();         return factory.getobject();     }       @primary     @bean(name = "commondatasource")     public datasource commondatasource() {         drivermanagerdatasource datasource = new drivermanagerdatasource();         datasource.setdriverclassname("com.mysql.jdbc.driver");         datasource.seturl("jdbc:mysql://10.10.1.11:3306/database1?characterencoding=utf-8");         datasource.setusername("fpuser");         datasource.setpassword("fpdb$123456");          return datasource;     }      @primary     @bean(name = "commontransactionmanager")     public platformtransactionmanager commontransactionmanager() {         jpatransactionmanager transactionmanager = new jpatransactionmanager();            transactionmanager.setentitymanagerfactory(commonentitymanagerfactory());         return transactionmanager;     }      @bean     public persistenceexceptiontranslationpostprocessor exceptiontranslation() {         return new persistenceexceptiontranslationpostprocessor();     }  } 

second:

@configuration @enabletransactionmanagement @enablejparepositories(value = "com.mycompany.project.persistence.orm.module.profile",entitymanagerfactoryref = "profileentitymanagerfactory",transactionmanagerref = "profiletransactionmanager") public class persistenceconfigprofile {      public persistenceconfigprofile() {     }       properties additionalproperties() {         return new properties() {             {                   setproperty("hibernate.dialect", "org.hibernate.dialect.mysqldialect");                 setproperty("hibernate.hbm2ddl.auto", "update");                 setproperty("hibernate.show_sql", "true");                 setproperty("hibernate.enable_lazy_load_no_trans", "true");                 setproperty("hibernate.connection.charset", "utf8");                 setproperty("hibernate.connection.characterencoding", "utf8");                 setproperty("hibernate.connection.useunicode", "true");             }         };      }      @primary     @bean(name = "profileentitymanagerfactory")     public entitymanagerfactory profileentitymanagerfactory() {entitymanagerfactorybean");         localcontainerentitymanagerfactorybean factory = new localcontainerentitymanagerfactorybean();         factory.setpersistenceunitname("profile");         factory.setdatasource(profiledatasource());         factory.setpackagestoscan("com.mycompany.project.persistence.orm.module");          hibernatejpavendoradapter vendoradapter = new hibernatejpavendoradapter();         vendoradapter.setgenerateddl(boolean.true);         vendoradapter.setshowsql(boolean.true);         factory.setjpavendoradapter(vendoradapter);         factory.setjpaproperties(additionalproperties());          factory.afterpropertiesset();         return factory.getobject();     }       @primary     @bean(name = "profiledatasource")     public datasource profiledatasource() {         drivermanagerdatasource datasource = new drivermanagerdatasource();         datasource.setdriverclassname("com.mysql.jdbc.driver");         datasource.seturl("jdbc:mysql://10.10.1.63:3306/database2?characterencoding=utf-8");         datasource.setusername("fpuser");         datasource.setpassword("fpdb$123456");          return datasource;     }      @primary     @bean(name = "profiletransactionmanager")     public platformtransactionmanager commontransactionmanager() {         jpatransactionmanager transactionmanager = new jpatransactionmanager();            transactionmanager.setentitymanagerfactory(commonentitymanagerfactory());         return transactionmanager;     }      @bean     public persistenceexceptiontranslationpostprocessor exceptiontranslation() {         return new persistenceexceptiontranslationpostprocessor();     }  } 

note similar in these 2 files, common has been converted profile in second file , database name , ip has been changed. in daos have put this:

@persistencecontext(unitname = "common") //or "profile" protected entitymanager entitymanager;  @override public entitymanager getentitymanager() {     return entitymanager; } 

now, when run project, following exception:

 org.springframework.beans.factory.nouniquebeandefinitionexception: no qualifying bean of type [javax.persistence.entitymanagerfactory] defined: expected single matching bean found 2: commonentitymanagerfactory,profileentitymanagerfactory 

i have bee stuck in exception 2 days. me solve problem. time.

you have not defined "common" unitname , have 2 @primary annotations. try configuring: @bean(name = "common") instead @bean(name = "commonentitymanagerfactory")
