I am working on Spring project. In this project I have password encoder bean.
#Configuration
public class AppSecurityConfiguration extends WebSecurityConfigurerAdapter {
public AppSecurityConfiguration() {
System.out.println("\n\n " + getClass().getName() + "\n\n\n");
}
#Autowired
private UserService userService;
#Bean
public PasswordEncoder defaultPasswordEncoder() {
System.out.println("\n\n\n bean is created!!!!! \n\n\n");
return new BCryptPasswordEncoder();
}
// other configurations
}
And the class where injection is required is this,
#Component
public class Encoders {
private static PasswordEncoder bCryptPasswordEncoder;
#Autowired
private PasswordEncoder defaultPasswordEncoder;
public Encoders() throws UnsupportedEncodingException {
System.out.println("\n\n\n " + (defaultPasswordEncoder == null) + " \n\n\n"); // this has problem, as defaultPasswordEncoder is null.
Encoders.bCryptPasswordEncoder = defaultPasswordEncoder;
}
// other methods
}
The defaultPasswordEncoder in the above class is null even though I have autowired this field.
The logs are showing that although the appSecurityConfiguration bean was made before encoder bean still the defaultPasswordEncoder bean is being created after encoder bean.
Here is the log,
2021-10-31 10:28:51.644 DEBUG 58508 --- [ restartedMain] o.s.b.f.s.DefaultListableBeanFactory : Creating shared instance of singleton bean 'appSecurityConfiguration'

2021-10-31 10:28:51.695 DEBUG 58508 --- [ restartedMain] o.s.b.f.s.DefaultListableBeanFactory : Creating shared instance of singleton bean 'encoders'

bean is created!!!!! // coming from AppSecurityConfiguration#defaultPasswordEncoder
I have also tried depends on annotation,
#Component
#DependsOn("defaultPasswordEncoder")
public class Encoders {
// rest is same
}
Now in logs defaultPasswordEncoder bean is being created before encoders but still the injection is not happening and the PasswordEncoder defaultPasswordEncoder field is null.
Here is the log,
2021-10-31 10:28:51.644 DEBUG 58508 --- [ restartedMain] o.s.b.f.s.DefaultListableBeanFactory : Creating shared instance of singleton bean 'appSecurityConfiguration'

true // still the field is null.
Can someone tell what is happening? And to resolve this issue?
Use constructor injection instead of property injection
public Encoders(PasswordEncoder defaultPasswordEncoder)
Then the bean will be available in constructor.
I have a class annotated with #Configuration and a bean
#Configuration
public class ExampleServiceConfig {
#Bean
#ConditionalOnProperty(value = servicefeature1.enable", havingValue = "true")
public ExampleServices exampleServices() {
return new ExampleServices();
}
I then have another service class that depends on the bean above:
#ConditionalOnBean(ExampleServices.class)
public class AnotherService{
#Autowired
public AnotherService(ExampleServices exampleServices){
this.exampleServices = exampleServices
}
}
In the spring debug logs, I see the first bean is getting created:
2020-02-28 14:08:51.841 DEBUG 18158 --- [ main] o.s.b.f.s.DefaultListableBeanFactory : Creating shared instance of singleton bean 'exampleServices'
But the AnotherService() is not getting created:
AnotherService:
Did not match:
- #ConditionalOnBean (types: x.x.x.ExampleServices; SearchStrategy: all) did not find any beans of type x.x.x.ExampleServices (OnBeanCondition)
Why is the AnotherService() not getting created even though the ExampleService bean was created successfully?
Also, I see the "did not match" log after the ExampleService bean got created.
I think adding #DependsOn to the mix could fix your issue. Here is another answer, somewhat similar with your problem: https://stackoverflow.com/a/50518946/6908551
#Component
#ConditionalOnBean(ExampleServices.class)
#DependsOn("exampleServices")
public class AnotherService {
#Autowired
public AnotherService(ExampleServices exampleServices) {
this.exampleServices = exampleServices
}
}
everyone. I am new to WebMvcTest, and am learning to write a PostControllerTest. While the project runs well, the test does not work.

Description:
Field reCaptchaService in nz.p2.captcha.ReCaptchaAuthenticationFilter required a bean of type 'nz.p2.captcha.ReCaptchaService' that could not be found.
Action:
Consider defining a bean of type 'nz.p2.captcha.ReCaptchaService' in your configuration.
It tells me to do something with the ReCaptchaService; which isn't used with the PostController. Given the simplifed Controller class:
#Controller
public class PostController {
#Autowired
private PostService postService;
#RequestMapping(value = URI_POST_POST, method = RequestMethod.GET)
public ModelAndView get(#Valid Long mkid) throws IOException {
// do somthing here using postService;
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName(URI_POST_POST);
modelAndView.addObject("abc", abc);
return modelAndView;
}
}
The PostControllerTest class is here:
#RunWith(SpringRunner.class)
#WebMvcTest(controllers = PostController.class)
public class PostControllerTest {
private MockMvc mockMvc;
#Autowired
private WebApplicationContext webApplicationContext;
#MockBean
private PostController postControllereMock;
#Before
public void setUp() throws Exception {
mockMvc = MockMvcBuilders.standaloneSetup(webApplicationContext).build();
}
#Test
public void testList() throws Exception {
assertThat(this.postControllereMock).isNotNull();
mockMvc.perform(MockMvcRequestBuilders.get(URI_POST_POST + "?mkid=8044022272730561994"))
.andExpect(status().isOk())
.andExpect(content().contentType("text/html;charset=UTF-8"))
.andExpect(view().name(URI_POST_POST))
.andExpect(MockMvcResultMatchers.view().name(URI_POST_POST))
.andExpect(content().string(Matchers.containsString("I have put together some image galleries")))
.andDo(print());
}
}
I have to mention that the reCaptchaService is #Autowired in the ReCaptchaAuthenticationFilter, and the latter one is #Autowired and used here:
#Configuration
#EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.
// tl; nw
.and().csrf().disable()
.addFilterBefore(reCaptchaAuthenticationFilter, UsernamePasswordAuthenticationFilter.class)
// tl; nw
}
}
So, in this case, how can I test the PostController?
I have a problem regarding the proper setup of a H2 database in springboot + hibernate and would very much appreciate your help. I guess my problem is in the #Transaction Annotation, since the respective class throws a NullPointerException. Here is some background information:
The idea of the program (which is not yet finished) is that agents (class "AgentLogic") can calulate prices for specific tasks within a Multi-Agent System. In order to calculate the price, an agent draws parameters from a database. These parameters are needed for some Machine Learning algorithms (in class "MachineLearningSource"), which will calculate the price of the agent.
I would like to setup the configuration of the database WITHOUT using an XML File, similar to the example in http://www.baeldung.com/hibernate-4-spring
The project has the following structure:
Project Structure
UPDATED CODE AFTER INCORPORATING CHANGES FROM #StanislavL
The project is implemented in SpringBoot. Accordingly, I use the following Application class:
package org.schlago.mldb;
import...
#SpringBootApplication
public class Application {
public static void main(String[] args) {
// ConfigurableApplicationContext context = SpringApplication.run(Application.class, args);
SpringApplicationBuilder builder = new SpringApplicationBuilder(Application.class);
builder.headless(false);
ConfigurableApplicationContext context = builder.run(args);
}
}
The following class contains the configuration of the database in Spring Hibernate, called DataBaseConfig:
package org.schlago.mldb.database;
import...
#Configuration
#Profile("param_db")
#EnableTransactionManagement
#ComponentScan({"org.schlago.mldb.mapping","org.schlago.mldb.machineLearning"})
public class DatabaseConfig {
#Autowired
private Environment env;
#Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getProperty("datasource.driver"));
dataSource.setUrl(env.getProperty("datasource.url"));
dataSource.setUsername(env.getProperty("datasource.username"));
dataSource.setPassword(env.getProperty("datasource.password"));
return dataSource;
}
#Bean
public LocalSessionFactoryBean sessionFactory(){
LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
sessionFactoryBean.setDataSource(dataSource());
sessionFactoryBean.setPackagesToScan(env.getProperty("entitymanager.packagesToScan"));
Properties hibernateProperties = new Properties();
hibernateProperties.put("hibernate.dialect", env.getProperty("jpa.hibernate.dialect"));
hibernateProperties.put("hibernate.show_sql", env.getProperty("jpa.hibernate.show-sql"));
hibernateProperties.put("hibernate.hbm2ddl.auto", env.getProperty("jpa.hibernate.hbm2ddl.auto"));
hibernateProperties.put("spring.jpa.hibernate.ddl-auto", env.getProperty("jpa.hibernate.ddl-auto"));
sessionFactoryBean.setHibernateProperties(hibernateProperties);
return sessionFactoryBean;
}
#Bean
#Autowired
public HibernateTransactionManager transactionManager(SessionFactory sessionFactory){
HibernateTransactionManager transactionManager = new HibernateTransactionManager();
transactionManager.setSessionFactory(sessionFactory);
return transactionManager;
}
#Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
}
This configuration uses the following environment (#Profile) in order to setup the sessionFactoryBean, called appliation.yaml:
spring.profiles: param_db
datasource:
driver: org.h2.Driver
url: jdbc:h2:tcp://localhost/~/test
username: sa
password:
jpa:
hibernate.show-sql: true
hibernate.hbm2ddl.auto: none
hibernate.dialect: org.hibernate.dialect.H2Dialect
hibernate.ddl-auto: validate
hibernate.globally_quoted_identifiers: true
entitymanager:
packagesToScan: org.schlago.mldb.mapping
Parameters shall be inserted to the database via a DAO, using a #Transactional Annotation. This DAO is called ParametersDao:
package org.schlago.mldb.mapping;
import ...
#Transactional
public class ParametersDao {
#Autowired
private SessionFactory _sessionFactory;
private Session getSession() {
return _sessionFactory.getCurrentSession();
}
public void save(Parameters parameters) { getSession().save(parameters); }
public void update(Parameters parameters) {
getSession().update(parameters);
}
public List<Parameters> getAllParameters() {
return getSession().createQuery("from Parameters").list();
}
public Parameters getParameterById(int id) {
List<Parameters> parametersList = getSession()
.createQuery("from Parameters where paramId = :theId")
.setParameter("theId", id).list();
if (parametersList.size() == 0) {
return null;
}
return parametersList.get(0);
}
}
Parameters are specified via the Paramters class:
package org.schlago.mldb.mapping;
#Entity
#Table(name = "mlparam")
public class Parameters {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long paramId;
#Column(name = "name")
private String name;
#Column(name = "value")
private double value;
#Column(name = "timestamp")
private Date timestamp;
public Parameters(){
}
public long getParamId() {
return paramId;
}
public void setParamId(int paramId) {
this.paramId = paramId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public double getValue() {
return value;
}
public void setValue(double value) {
this.value = value;
}
public Date getTimestamp() {
return timestamp;
}
public void setTimestamp(Date timestamp) { this.timestamp = timestamp; }
}
I think there is an error in the way ParametersDao is setup. However, for your better understanding, here are the other classes used within this project. The following class is AgentLogic, which will calculate a price upon request in a later strange of the code. Since the code is still in an early stage, I used #PostConstruct rather than a request, in order to test if the price calulation works:
package org.schlago.mldb.logic;
import...
#Component
public class AgentLogic {
private static final Logger LOGGER = LoggerFactory.getLogger(Application.class);
#Autowired
private MachineLearningSource machineLearningSource;
#PostConstruct
public void init(){
int priceInCent = 50;
priceInCent = machineLearningSource.getPrice(getAgent());
LOGGER.info("Answered with offer about " + priceInCent + " Cents.");
}
// DUMMY class: Return a new agent
public static Agent getAgent(){
// Currently, an Agent is just an (empty) dummy class
Agent agent = new Agent();
return agent;
}
}
Finally, the following class is responsible for price calcuation. Since the code is still in an early stage, price calculation is set randomly, rather than implementing machinelearning algorithms. In the method getParameters(), some Parameters are inserted to the dataBase for testing purposes:
package org.schlago.mldb.machineLearning;
import org.schlago.mldb.Nodes.Agent;
import org.schlago.mldb.mapping.Parameters;
import org.schlago.mldb.mapping.ParametersDao;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import java.util.Date;
import java.util.HashMap;
import java.util.Random;
#Component
public class MachineLearningSource {
#Autowired
ParametersDao parametersDao;
private static final Logger LOGGER = LoggerFactory.getLogger(MachineLearningSource.class);
public int getPrice(Agent agent) {
Random r = new Random();
int thePrice = r.nextInt(99) + 1;
LOGGER.info("The price is dynamically calculated right now!");
HashMap<String, Double> parameters = getParameters();
return thePrice;
}
public HashMap<String, Double> getParameters() {
HashMap<String, Double> equationParameters = new HashMap<>();
// TEST: Since database is currently empty, parameters are inserted manually here (this will change later)
LOGGER.info("About to insert into table");
Parameters myCalcParams = new Parameters();
myCalcParams.setName("kappa");
myCalcParams.setValue(2.39583992);
myCalcParams.setTimestamp(new Date());
parametersDao.save(myCalcParams);
LOGGER.info("Successfully inserted parameters");
/*
// Get the parameters via parametersDao, work in progress!
List<Parameters> parameters = parametersDao.getAllParameters();
Parameters myParam = parametersDao.getParameterById(3748);
if (myParam == null) {
LOGGER.info("Dataset does not exist!");
}
for (Parameters param : parameters) {
equationParameters.put(param.getName(), param.getValue());
LOGGER.info("Actual parameter for price calculation: " + param.getName());
LOGGER.info("Value: " + param.getValue());
}
*/
// TEST: Return dummy equationParameters
equationParameters.put("a", 2.48238948239);
equationParameters.put("b", 8.23482489729);
return equationParameters;
}
}

Try to add #Component annotation to the MachineLearningSource service class and check both dao and the service are included in the #ComponentScan
UPDATE
In the AgentLogic you manually create the machineLearningSource
MachineLearningSource machineLearningSource = new MachineLearningSource();
priceInCent = machineLearningSource.getPrice(getAgent());
Instead add
#Autowired
private MachineLearningSource machineLearningSource;
To the class to let Spring initialize this properly. Or you can autowire dao in the class and manually call
machineLearningSource.setDao(theAutowiredDao);
UPDATE2:
Now the dao is not marked to be detected as a spring bean. Add #Repository annotation to the DAO.
UPDATE3:
sessionFactoryBean.setPackagesToScan(env.getProperty("entitymanager.packagesToScan"));
check which exactly packages are scanned there. Need to have all packages where your entity classes are stored.
I have a Spring bean defined, but when I am add the last 4 lines for Autowiring another RestClient rest bean, I am getting error (If I remove the last 3 lines, my spring container loads fine):
#Component
public class TimeseriesServiceImpl {
private static Logger log = Logger.getLogger(TimeseriesServiceImpl.class);
#PostConstruct
public void init() {
System.out.println("MyService init method called");
}
#PreDestroy
public void destory(){
System.out.println("MyService destroy method called");
}
#Autowired
#Qualifier("restClient")
public RestClient rest ;

if(poolManager !=null ) {
poolManager.setMaxTotal(this.restConfig.getOauthPoolMaxSize());
poolManager.setDefaultMaxPerRoute(this.restConfig.getOauthPoolMaxSize());
}
}
Do not include * while specifying the basePackages attribute in the #ComponentScan Annotation.
So replace the same with the code below -
#ComponentScan(basePackages={"com.tcs.timeseries","com.ge.predix.solsvc.restclient.config", "com.ge.predix.solsvc.restclient.impl"})
This will properly scan the packages and sub-packages.
The issue was with the profile declaration, in properties file where I need to mention as local. After I created application.properties file in config folder and put this line spring.profiles.active=local , it was able to inject RestClient bean without any issue
