im using jhipster version 7.6.0 and this is my CacheConfiguration class.
#Configuration
#EnableCaching
public class CacheConfiguration {
private GitProperties gitProperties;
private BuildProperties buildProperties;
#Bean
public javax.cache.configuration.Configuration<Object, Object> jcacheConfiguration(JHipsterProperties jHipsterProperties) {
MutableConfiguration<Object, Object> jcacheConfig = new MutableConfiguration<>();
URI redisUri = URI.create(jHipsterProperties.getCache().getRedis().getServer()[0]);
Config config = new Config();
if (jHipsterProperties.getCache().getRedis().isCluster()) {
ClusterServersConfig clusterServersConfig = config
.useClusterServers()
.setMasterConnectionPoolSize(jHipsterProperties.getCache().getRedis().getConnectionPoolSize())
.setMasterConnectionMinimumIdleSize(jHipsterProperties.getCache().getRedis().getConnectionMinimumIdleSize())
.setSubscriptionConnectionPoolSize(jHipsterProperties.getCache().getRedis().getSubscriptionConnectionPoolSize())
.addNodeAddress(jHipsterProperties.getCache().getRedis().getServer());
if (redisUri.getUserInfo() != null) {
clusterServersConfig.setPassword(redisUri.getUserInfo().substring(redisUri.getUserInfo().indexOf(':') + 1));
}
} else {
SingleServerConfig singleServerConfig = config
.useSingleServer()
.setConnectionPoolSize(jHipsterProperties.getCache().getRedis().getConnectionPoolSize())
.setConnectionMinimumIdleSize(jHipsterProperties.getCache().getRedis().getConnectionMinimumIdleSize())
.setSubscriptionConnectionPoolSize(jHipsterProperties.getCache().getRedis().getSubscriptionConnectionPoolSize())
.setAddress(jHipsterProperties.getCache().getRedis().getServer()[0]);
if (redisUri.getUserInfo() != null) {
singleServerConfig.setPassword(redisUri.getUserInfo().substring(redisUri.getUserInfo().indexOf(':') + 1));
}
}
jcacheConfig.setStatisticsEnabled(true);
jcacheConfig.setExpiryPolicyFactory(
CreatedExpiryPolicy.factoryOf(new Duration(TimeUnit.SECONDS, jHipsterProperties.getCache().getRedis().getExpiration()))
);
return RedissonConfiguration.fromInstance(Redisson.create(config), jcacheConfig);
}
Here is dependency for redisson :
<dependency>
<groupId>org.redisson</groupId>
<artifactId>redisson</artifactId>
</dependency>
This is my application-dev.yml:
Everything is generated by jHipster and after installation of redis version 3.2.100, im getting this exception:

Project is compiling successfully by the way.
Thanks in advance for help!
It's seem related to Redis works.
You can checkout docs: https://www.baeldung.com/hibernate-second-level-cache move to "What Is a Second-Level Cache".
First, enable bean "hibernatePropertiesCustomizer" in CacheConfiguration.java:
import org.hibernate.cache.jcache.ConfigSettings;
#Bean
public HibernatePropertiesCustomizer hibernatePropertiesCustomizer(CacheManager cm) {
return hibernateProperties -> hibernateProperties.put(ConfigSettings.CACHE_MANAGER, cm);
}
Unfortunately, Redis in Jhipster don't initial cache for each entity model, so you must to initial cache for each model in domain package, like:
#Bean
public JCacheManagerCustomizer cacheManagerCustomizer(javax.cache.configuration.Configuration<Object, Object> jcacheConfiguration) {
return cm -> {
// jhipster-needle-redis-add-entry
createCache(cm, com.project.model.YourModel1.class.getName(), jcacheConfiguration);
createCache(cm, com.project.model.YourModel2.class.getName(), jcacheConfiguration);
};
}
Please add all your Model(Entity class) using #Cache annotation.
Good luck,

I have a problem in running any test method in service test and controller test in one of the spring boot microservices (order service).
After I completed service and controller , I tried to write their test methods but I have a problem in there.
How can I fix it?
Here is the security config of order service?
#Configuration
#EnableWebSecurity(debug = true)
#EnableGlobalMethodSecurity(prePostEnabled = true)
#RequiredArgsConstructor
public class SecurityConfig {
//
private final JwtAuthenticationEntryPoint authenticationEntryPoint;
private final JWTAccessDeniedHandler accessDeniedHandler;
private final JwtAuthenticationFilter jwtAuthenticationFilter;
#Bean(BeanIds.AUTHENTICATION_MANAGER)
public AuthenticationManager authenticationManager(final AuthenticationConfiguration authenticationConfiguration) throws Exception {
return authenticationConfiguration.getAuthenticationManager();
}
#Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
return http
.csrf().disable()
.authorizeRequests()
.antMatchers(HttpMethod.POST, "/order/**").hasRole("USER")
.antMatchers(HttpMethod.GET, "/order/**").hasRole("USER")
.and()
.authorizeRequests().anyRequest().authenticated()
.and()
.formLogin().disable()
.httpBasic().disable()
.exceptionHandling()
.authenticationEntryPoint(authenticationEntryPoint)
.accessDeniedHandler(accessDeniedHandler)
.and()
.addFilterBefore(jwtAuthenticationFilter, UsernamePasswordAuthenticationFilter.class)
.build();
}
#Bean
public WebSecurityCustomizer webSecurityCustomizer() {
return (web)
-> web.ignoring().antMatchers("/authenticate/signup", "/authenticate/login", "/authenticate/refreshtoken");
}
}
Here is one of the test method of OrderServiceTest shown below
#DisplayName("Get Order - Success Scenario")
#Test
void test_When_Order_Success() {
//Mocking
Order order = getMockOrder();
when(orderRepository.findById(anyLong()))
.thenReturn(Optional.of(order));
when(restTemplate.getForObject(
"http://PRODUCT-SERVICE/product/" + order.getProductId(),
ProductResponse.class
)).thenReturn(getMockProductResponse());
when(restTemplate.getForObject(
"http://PAYMENT-SERVICE/payment/order/" + order.getId(),
PaymentResponse.class
)).thenReturn(getMockPaymentResponse());
//Actual
OrderResponse orderResponse = orderService.getOrderDetails(1);
//Verification
verify(orderRepository, times(1)).findById(anyLong());
verify(restTemplate, times(1)).getForObject(
"http://PRODUCT-SERVICE/product/" + order.getProductId(),
ProductResponse.class);
verify(restTemplate, times(1)).getForObject(
"http://PAYMENT-SERVICE/payment/order/" + order.getId(),
PaymentResponse.class);
//Assert
assertNotNull(orderResponse);
assertEquals(order.getId(), orderResponse.getOrderId());
}
Here is one of the test method of OrderControllerTest shown below.
#Test
#DisplayName("Place Order -- Success Scenario")
#WithMockUser(username = "User", authorities = { "ROLE_USER" })
void test_When_placeOrder_DoPayment_Success() throws Exception {
OrderRequest orderRequest = getMockOrderRequest();
String jwt = getJWTTokenForRoleUser();
MvcResult mvcResult
= mockMvc.perform(MockMvcRequestBuilders.post("/order/placeorder")
.contentType(MediaType.APPLICATION_JSON_VALUE)
.header("Authorization", "Bearer " + jwt)
.content(objectMapper.writeValueAsString(orderRequest)))
.andExpect(MockMvcResultMatchers.status().isOk())
.andReturn();
String orderId = mvcResult.getResponse().getContentAsString();
Optional<Order> order = orderRepository.findById(Long.valueOf(orderId));
assertTrue(order.isPresent());
Order o = order.get();
assertEquals(Long.parseLong(orderId), o.getId());
assertEquals("PLACED", o.getOrderStatus());
assertEquals(orderRequest.getTotalAmount(), o.getAmount());
assertEquals(orderRequest.getQuantity(), o.getQuantity());
}
Here is the error when I run any method of service test and controller shown below.

Replace
#Bean(BeanIds.AUTHENTICATION_MANAGER)
public AuthenticationManager authenticationManager(final AuthenticationConfiguration authenticationConfiguration) throws Exception {
return authenticationConfiguration.getAuthenticationManager();
}
with
#Bean
public AuthenticationManager authenticationManager(List<AuthenticationProvider> myAuthenticationProviders) {

}
in secuity config of order service.
Here is the error message shown below.

The error is most likely caused by declaring the AuthenticationManager as a #Bean. Try this in your test class:
#MockBean
private AuthenticationManager _authenticationManager;
That said, the Spring Security team does not recommend exposing the AuthenticationManager in this way, see the comment in Spring issue #29215
i need a simple crud for LDAP in java im follows the next tutorial :
https://github.com/eugenp/tutorials/tree/master/spring-security-modules/spring-security-ldap
but i cant do it work....
i only need get work this class in a new code for a SIMPLE LDAP CRUD....

}
How i can get a simple LDAP CRUD with above functionalities?
i need create and edit params user LDAP is for study...
if you know other way to get the CRUD on LDAP please let me know...
Thanks..

I tried to register my driver class so that my spring application uses custom driver internally ? My application.properties file config is as follows
spring.datasource.url=jdbc:postgresql://localhost:5438/postgres
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.jpa.show-sql=true
spring.datasource.driverClassName=com.example.ksql.KDriver
## Hibernate Properties
# The SQL dialect makes Hibernate generate better SQL for the chosen database
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
#Hibernate ddl auto (create, create-drop, validate, update)
spring.jpa.hibernate.ddl-auto = update
server.port=8080
Basically, I have implemented java.sql interfaces and inside override methods I am making actual db method calls like postgres, mysql etc.
But when I run my application it shows error like -
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'dataSourceScriptDatabaseInitializer' defined in class path resource [org/springframework/boot/autoconfigure/sql/init/DataSourceInitializationConfiguration.class]: Unsatisfied dependency expressed through method 'dataSourceScriptDatabaseInitializer' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.RuntimeException: Failed to instantiate class com.example.ksql.KDriver

I want to know is it really a right way to use custom driver class internally by jpa or I have to do something else ??
My driver class looks like this -
package com.example.ksql;
//import com.mysql.cj.jdbc.Driver;
import org.postgresql.Driver;
import java.sql.Connection;
import java.sql.DriverPropertyInfo;
import java.sql.SQLException;
import java.sql.SQLFeatureNotSupportedException;
import java.util.Properties;
import java.util.logging.Logger;
public class KDriver implements java.sql.Driver {
public Driver wrappedDriver;
private String _url;
private String _username;
private String _password;
private String _databaseName;
private Integer _version = 1;
private Connection _connection;
public Boolean _isConnected = false;
private String _lastInsertId = "-1";
public KDriver(String url, String user, String password) throws SQLException {
_url = url;
_username = user;
_password = password;
}
#Override
public Connection connect(String _url, Properties info) throws SQLException {
wrappedDriver = new Driver();
_connection = wrappedDriver.connect(_url, info);
Connection kobj = new KConnection(_connection);
return kobj;
}
#Override
public boolean acceptsURL(String url) throws SQLException {
boolean acceptsURL = wrappedDriver.acceptsURL(url);
return acceptsURL;
}
#Override
public DriverPropertyInfo[] getPropertyInfo(String url, Properties info) throws SQLException {
return new DriverPropertyInfo[0];
}
#Override
public int getMajorVersion() {
int getMajor = wrappedDriver.getMajorVersion();
return getMajor;
}
#Override
public int getMinorVersion() {
int getMinor = wrappedDriver.getMinorVersion();
return getMinor;
}
#Override
public boolean jdbcCompliant() {
boolean jdbcCompliant = wrappedDriver.jdbcCompliant();
return jdbcCompliant;
}
#Override
public Logger getParentLogger() throws SQLFeatureNotSupportedException {
return wrappedDriver.getParentLogger();
}
}
You seem what you want to use postgress so configure a standard postgress drivers and add postgress driver jar with maven.
spring.database.driverClassName=org.postgresql.Driver
Not strange
spring.datasource.driverClassName=com.example.ksql.KDriver

Do you know how I can fix this issue?
The error stack trace is indicating that a NullPointerException is happening when you are creating a new instance of DefaultKafkaProducerFactory in the producerFactory() method.
Internally, DefaultKafkaProducerFactory creates a ConcurrentHashMap with the provided information to maintain its configuration.
As you can see in the ConcurrentHashMap javadocs, the put method will raise NullPointerException if any of the provided keys or values are null.
As a consequence, probably one of or several of the variables keySerializer, valueSerializer or bootstrapServers are null.
I assume these values are filled by dependency injection according to your #ConfigurationProperties kafka.status.producer. Please, be sure these properties are correctly defined in your Spring configuration.
For testing purposes, try removing the #RefreshScope annotation: it may be a cause of the problem.
The contrary can be a valid solution as well. As indicated in the Spring Cloud documentation when talking about #RefreshScope:
#RefreshScope works (technically) on a #Configuration class,
but it might lead to surprising behavior. For example, it does not
mean that all the #Beans defined in that class are themselves in
#RefreshScope. Specifically, anything that depends on those beans
cannot rely on them being updated when a refresh is initiated, unless
it is itself in #RefreshScope. In that case, it is rebuilt on a
refresh and its dependencies are re-injected. At that point, they are
re-initialized from the refreshed #Configuration).
From that point of view if make perfect sense to annotate with #RefreshScope the producerFactory bean as well. I would try:
import org.apache.kafka.clients.producer.ProducerConfig;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.kafka.core.DefaultKafkaProducerFactory;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.kafka.core.ProducerFactory;
import java.util.HashMap;
import java.util.Map;
#Configuration
#RefreshScope
#ConfigurationProperties(prefix = "kafka.status.producer")
public class StatusKafkaProducerConfig {
private String keySerializer;
private String valueSerializer;
private String bootstrapServers;
public void setKeySerializer(String keySerializer) {
this.keySerializer = keySerializer;
}
public void setValueSerializer(String valueSerializer) {
this.valueSerializer = valueSerializer;
}
public void setBootstrapServers(String bootstrapServers) {
this.bootstrapServers = bootstrapServers;
}
#Bean
#RefreshScope
public Map<String, Object> producerConfigs() {
Map<String, Object> properties = new HashMap<>();
properties.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, keySerializer);
properties.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, valueSerializer);
properties.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
return properties;
}
#Bean
#RefreshScope
public KafkaTemplate<String, String> kafkaTemplate() {
return new KafkaTemplate<>(producerFactory());
}
#Bean
#RefreshScope
public ProducerFactory<String, String> producerFactory() {
return new DefaultKafkaProducerFactory<>(producerConfigs());
}
}
Please, note the inclusion of the additional #RefreshScope annotations.
Finally, consider review the Spring Kafka project documentation, it provides several examples about how to configure your project, whether you are using Spring Boot or not, and gives you further background about DefaultKafkaProducerFactory.
As you can see in the aforementioned docs, if you are using Spring Boot, like in you case, the code can be greatly simplified. Consider review the Spring Boot related documentation about the subject and related properties configuration.
i'm using SpringBoot and i'm trying to connect to an oracle db.
Following a tutorial i wrote the following code that cause the following exception.
I'm not understing where the problem is, on executing factoryBean.afterPropertiesSet(); it crashes.
Some suggestion?

Edit:
Once i correct the crash by adding the missing dependency, i'm still having trouple feeding the sessionFactory. Here's the class:
#Repository
#Transactional
public class ConnectionDAO {
#Autowired
private SessionFactory sessionFactory;
public Customer getCustomer(String name){
return new Customer("","");
}
public Boolean setCustomer(String name, String surname){
/*
*
*/
return false;
}
}
You are missing: org.threeten.bp.Instant
So add this dependency to your build (update with appropriate version):
<dependency>
<groupId>org.threeten</groupId>
<artifactId>threetenbp</artifactId>
<version>1.3.3</version>
</dependency>
