title=SpringApp

greeting=Greetings, it is now
priceincrease.heading=Price Increase :: SpringApp
error.not-specified=Percentage not specified!!!
error.too-low=You have to specify a percentage higher than {0}!
error.too-high=Don''t be greedy - you can''t raise prices by more than {0}%!
required=Entry required.
typeMismatch=Invalid data.
typeMismatch.percentage=That is not a number!!!
The problem is I not getting the messages I've defined e.g when I insert 65 in the percentaje field I'm not getting the following message: Don''t be greedy - you can''t raise prices by more than {0}%!. Instead of this I'm getting the default message.
I've deleted the code asociated to the autowired annotation just to make the post shorter.
You must know the application works fine, the problems are in the returned messages.
How can I show the messages that I want?

This post explains in detail how to do validation in spring mvc. Click Here

You just need to implement the Validator here's a simple example...
public class PriceIncreaseValidator implements Validator {
#Override
public boolean supports( Class<?> clazz ) {
return PriceIncrease.class.equals(clazz);
}
#Override
public void validate( Object o, Errors e ) {
PriceIncrease priceIncrease = (PriceIncrease) o;
if( priceIncrease.getPercentage() == 0 ) {
e.rejectValue( "priceIncrease", "error.too-low");
} else if( priceIncrease.getPercentage() >= 50 ) {
e.rejectValue( "priceIncrease", "error.too-high");
}
}
}

Spring annotations #NotNull and #Size do not work

I've created a simple page project, which checks a single inputdata field "name" and if it's empty or size is less than 5, it has to show a error-message.
At the moment BindingResult thinks there is no error all the time.

The project worked well before the applicationContext file was modified,
but after the code has been modified, an error occurs.
error code is that.
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'adminService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private dao.IAdminDAO service.AdminService.adminDao; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [dao.IAdminDAO] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}

at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:537)
I thought about the cause of the error,
but I think it is because I did not insert the service annotation.
However, there is no typos in any way, and everything is written correctly and errors occur. Is there something I don't know?
Can you tell me what caused this error?
And what about the solution?
Please help me..

Try to change this code of yours:
#Autowired
public AdminService aService;
to this:
#Autowired
public AdminService adminService;
because when you Autowire, he can't see aService on your context that's why he can't create instance of adminService as a default name of your Service bean.
EDIT:
Another thing is you have to implement your interfaces to a concrete class in order to instantiate beans, you can't instantiate interfaces remember, so you need concrete beans to implement what is on your interfaces. Like this:
#Repository
public class IAdminDAOImpl implements IAdminDAO {
//Implementation here
}
#Service
public class AdminServiceImpl implements AdminService {
//Implementation here
}

thank you #mechkov for your time and help,
My problem is resolved by changing my configuration file, so I have used a Configuration Class with annotations and its works so fine, I still Don't know where the problem was
#Configuration
#ComponentScan(basePackages = "your package")
#EnableTransactionManagement
public class DatabaseConfig {
protected static final String PROPERTY_NAME_DATABASE_DRIVER = "com.mysql.jdbc.Driver";
protected static final String PROPERTY_NAME_DATABASE_PASSWORD = "password";
protected static final String PROPERTY_NAME_DATABASE_URL = "jdbc:mysql://localhost:3306/databasename";
protected static final String PROPERTY_NAME_DATABASE_USERNAME = "login";
private static final String PROPERTY_PACKAGES_TO_SCAN = "where your models are";
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter){
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource);
entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter);
entityManagerFactoryBean.setPackagesToScan(PROPERTY_PACKAGES_TO_SCAN);
return entityManagerFactoryBean;
}
#Bean
public BasicDataSource dataSource(){
BasicDataSource ds = new BasicDataSource();
ds.setDriverClassName(PROPERTY_NAME_DATABASE_DRIVER);
ds.setUrl(PROPERTY_NAME_DATABASE_URL);
ds.setUsername(PROPERTY_NAME_DATABASE_USERNAME);
ds.setPassword(PROPERTY_NAME_DATABASE_PASSWORD);
ds.setInitialSize(5);
return ds;
}
#Bean
public JpaVendorAdapter jpaVendorAdapter(){
HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setDatabase(Database.MYSQL);
adapter.setShowSql(true);
adapter.setGenerateDdl(true);
//I'm using MySQL5InnoDBDialect to make my tables support foreign keys
adapter.setDatabasePlatform("org.hibernate.dialect.MySQL5InnoDBDialect");
return adapter;
}
#Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
return new JpaTransactionManager(entityManagerFactory);
}
}

I do not know if anyone who is reading this (today) has the same case as mine, but I had the same problem. Luckly, I could fix it by simply putting the following in my spring-conf.xml:
<beans xmlns="http://www.springframework.org/schema/beans"
...
xmlns:tx="http://www.springframework.org/schema/tx"
...
xsi:schemaLocation="
...
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<bean id="tManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="emf" />
</bean>
<!-- This does the trick! -->
<tx:annotation-driven transaction-manager="tManager" />
Note: I'm using declarative transactions through annotations. So, if you do, annotating your method with #Transactional can also solve your problem.
REFERENCE:
http://blog.jhades.org/how-does-spring-transactional-really-work/
http://docs.spring.io/spring-framework/docs/current/spring-framework-reference/html/transaction.html

Just to confirm, that adding last bean definition solves this issue !
My config class is as below :
#Configuration
#EnableTransactionManagement
#ComponentScan
public class OFSConfig {
#Bean
public IDAO<FuelStation> getFSService() {
return new FSService();
}
#Bean
public LocalEntityManagerFactoryBean emfBean() {
LocalEntityManagerFactoryBean e = new LocalEntityManagerFactoryBean();
e.setPersistenceUnitName("org.superbapps.db_OWSDB_PU");
return e;
}
#Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory em) {
return new JpaTransactionManager(em);
}
}
The service itself is as follows :
#Transactional
#Repository
public class FSService implements IDAO<FuelStation> {
#PersistenceContext
private EntityManager EM;
public EntityManager getEM() {
return EM;
}
public void setEM(EntityManager EM) {
this.EM = EM;
}
#Override
public List<FuelStation> getAll() {
return EM.createNamedQuery("FuelStation.findAll")
.getResultList();
}
#Override
public FuelStation getByID(String ID) {
FuelStation fs = (FuelStation) EM.createNamedQuery("FuelStation.findById")
.setParameter("id", ID)
.getSingleResult();
return fs;
}
#Override
public void update(FuelStation entity) {
EM.merge(entity);
}
}

Autowired Field is Null

Im have been working on a example for spring MVC + Spring Security + hibernate to make a login page, but now i have come to a problem with a fuel #Autowire that keeps giving me null values. the server doesnt report any errors its just that it doesnt complete the operation.
CustomUSerDetailsService.java
package com.carloscortina.paidosSimple.service;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
import org.slf4j.Logger;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import com.carloscortina.paidosSimple.dao.UsuarioDao;
import com.carloscortina.paidosSimple.model.Usuario;
#Service
#Transactional(readOnly=true)
public class CustomUserDetailsService implements UserDetailsService {
private static final Logger logger = LoggerFactory.getLogger(CustomUserDetailsService.class);
#Autowired UsuarioDao userDao;
#Override
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException {
logger.info(username);
Usuario domainUser = userDao.getUsuario(username);
logger.info(domainUser.getUsername());
boolean enabled = true;
boolean accountNonExpired = true;
boolean credentialsNonExpired = true;
boolean accountNonLocked = true;
return new User(
domainUser.getUsername(),
domainUser.getPassword(),
enabled,
accountNonExpired,
credentialsNonExpired,
accountNonLocked,
getAuthorities(domainUser.getRol().getId()));
}
public Collection<? extends GrantedAuthority> getAuthorities(Integer rol){
List<GrantedAuthority> authList = getGrantedAuthorities(getRoles(rol));
return authList;
}
public List<String> getRoles(Integer rol){
List<String> roles = new ArrayList<String>();
if(rol.intValue() == 1){
roles.add("ROLE_DOCTOR");
roles.add("ROLE_ASISTENTE");
}else if (rol.intValue() == 2){
roles.add("ROLE_ASISTENTE");
}
return roles;
}
public static List<GrantedAuthority> getGrantedAuthorities(List<String> roles){
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
for (String role : roles) {
authorities.add(new SimpleGrantedAuthority(role));
}
return authorities;
}
}
Here the field userDao keeps beign null so when i try to use userDao.getUsuario(username) the operation just doesnt continue, it doesn't report an error or similar its just gives me a 404- error

I dont know whats missing , so any idea its welcome, thanks in advance.

After trying to add a bean with UsuarioDaoImp i got this error:

i think I'm short in knowledge about the subject, that why i was following an example but i ended with this, so my apologise if I'm not giving the information correctly or if im misunderstanding concepts.

How are you accessing CustomUSerDetailsService class ? I hope you haven't added this class as bean in security config file or any other spring config?
Editted:
Your service bean is annotated with #service and you have also declared it in xml, spring has created two service beans one based on #service annotation (fully populated as its autowried) and second using the xml config (in which I assume you haven't injected dao dependency explicitly), so the second one doesnt have dao object set. As you are using the bean name of the service bean declared in your security config, you are getting userDao as null on debug.
Either comment the explicit bean definition in security xml, use ref="customUSerDetailsService" directly as #service annotation already added a bean with this name in spring context.
i.e. comment/remove this line in your security config and every thing should work.
<beans:bean class="com.carloscortina.paidosSimple.service.CustomUserDetailsService" id="customUserDetailsService"></beans:bean>
When you annotate a bean with #component/#service spring adds a bean with name equals to short classname(first letter lower case), so bean with name "customUserDetailsService" already exists, defining it explicitly in xml is overriding it.
Or declare all the bean definitions (including there dependencies) explicitly it xml config

Add the dao package to the component scan
<context:component-scan base-package="com.carloscortina.paidosSimple, com.carloscortina.paidosSimple.dao" />
