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'

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'

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'm learning Spring and Hibernate on my own. I have read few articles and tried to create Spring and Hibernate application without XML at all. I don't know why, but it doesn't work and in the end I get Error message:

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 am trying to invoke a rest endpoint, but getting this info when i call it, resulting in a 404 error in UI

There are 2 controller class in the same package with different endpoint
#RestController
public class OperationRetrievalController {
#Autowired
OperationRetrievalManager operationRetrievalManager;
private static Logger logger = Logger.getLogger(OperationRetrievalController.class);
#RequestMapping("/api/v1/operations")
public ResponseEntity<List<OperationView>> requestUserOperations() {
String ssoId = "xxxxxx";
logger.info("Inside request operationRetrivel Manager +++++++++>>>>>>>>");
return new ResponseEntity<List<OperationView>>(operationRetrievalManager.retrieveOperations(ssoId), HttpStatus.OK);
}
}
I have another class in the same package :
#RestController
public class ComponentRetrievalController {
#Autowired
ComponentRetrievalManager componentRetrievalManager;
#RequestMapping(value = "api/v1/component/{sso_id}" , method=RequestMethod.GET)
public ResponseEntity<List<Component>> requestUserComponent(#PathVariable("sso_id") String ssoId) {
return new ResponseEntity<List<Component>>(componentRetrievalManager.retrieveComponents(ssoId), HttpStatus.OK);
}
}
Here is the Spring boot app class :
#SpringBootApplication
#EnableAutoConfiguration
#EnableJpaRepositories(basePackages="com.ge.power.bis.repositories")
#ComponentScan(basePackages="com.ge.power.bis.managers")
public class Application {
private static Logger logger = Logger.getLogger(Application.class);
public static void main(String[] args) {
SpringApplication springApplication = new SpringApplication(Application.class);
ApplicationContext ctx = springApplication.run(args);
logger.info("Let's inspect the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames)
{
logger.info(beanName);
}
}
}
Here is the structure of my package
When I remove all the annotations in Application.java and just keeping the #SpringBootApplication, It gives the following error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'componentRetrievalController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.ge.power.bis.managers.ComponentRetrievalManager com.ge.power.bis.controllers.ComponentRetrievalController.componentRetrievalManager; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.ge.power.bis.managers.ComponentRetrievalManager] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

#Service was missing on one of the Impl class
You need to mark the service class as "Available to make beans" so the Spring's component-scan will be able to make bean and inject values.
This can be done by #Component annotation. As mentioned in the answer by #sromit, adding #Service annotation will also work, as it already inherits the #Component. #Repository and #Controller also inherit the #Component annotation.
