User.java
packagecom.gong.springmvc.entities; publicclassUser{ privateStringusername; privateStringpassword; privateStringemail; privateIntegerage; Addressaddress; publicStringgetUsername(){ returnusername; } publicvoidsetUsername(Stringusername){ this.username=username; } publicStringgetPassword(){ returnpassword; } publicvoidsetPassword(Stringpassword){ this.password=password; } publicStringgetEmail(){ returnemail; } publicvoidsetEmail(Stringemail){ this.email=email; } publicIntegergetAge(){ returnage; } publicvoidsetAge(Integerage){ this.age=age; } publicAddressgetAddress(){ returnaddress; } publicvoidsetAddress(Addressaddress){ this.address=address; } @Override publicStringtoString(){ return"User[username="+username+",password="+password+",email="+email+",age="+age +",address="+address+"]"; } }
Address.java
packagecom.gong.springmvc.entities; publicclassAddress{ privateStringcity; privateStringstreet; publicStringgetCity(){ returncity; } publicvoidsetCity(Stringcity){ this.city=city; } publicStringgetStreet(){ returnstreet; } publicvoidsetStreet(Stringstreet){ this.street=street; } @Override publicStringtoString(){ return"Address[city="+city+",street="+street+"]"; } }
SpringmvcTest.java
