I am running an annotation-based configuration project such as :
#Configuration
public class HibernateConfig {
private Map<String, String> map;
public HibernateConfig(){
init();
}
private void init(){
Properties props;
InputStream input = null;
try {
props = new Properties();
input = this.getClass().getClassLoader().getResourceAsStream("jdbc.properties");
props.load(input);
Enumeration<?> e = props.propertyNames();
while (e.hasMoreElements()) {
String key = (String) e.nextElement();
String value = props.getProperty(key);
map.put(key, value);
}
} catch (IOException e1) {
e1.printStackTrace();
} finally{
if(input!=null){
try {
input.close();
} catch (IOException e2) {
e2.printStackTrace();
}
}
}
}
#Bean(name="dataSource", destroyMethod = "close")
public DataSource getDataSource(){
ComboPooledDataSource dataSource = new ComboPooledDataSource();
try {
dataSource.setDriverClass(map.get("db.driverClass"));
dataSource.setJdbcUrl(map.get("db.jdbcUrl"));
dataSource.setUser(map.get("db.user"));
dataSource.setPassword(map.get("db.password"));
dataSource.setMaxPoolSize(50);

dataSource.setMaxIdleTime(1800);
dataSource.setAutoCommitOnClose(false);
dataSource.setInitialPoolSize(5);
} catch (PropertyVetoException e) {
e.printStackTrace();
}
return dataSource;
}
#Bean(name="sessionFactory")
#Scope("singleton")
public FactoryBean<SessionFactory> getSessionFactory(#Qualifier("dataSource") javax.sql.DataSource dataSource){

try {

I have been looking for a thread talking about the same issue I could not find any so far. Any one has an idea please?
UPDATE : Stacktrace added
Your are using Spring, then use Spring. Don't load your own properties, use a #PropertySource for that.
Remove your init method and replace that with an #PropertySource, then inject the Environment into your configuration and use that to retrieve properties.
#Configuration
#PropertySource("classpath:jdbc.properties")
public class HibernateConfig {
#Autowired
private Environment env;
#Bean
public DataSource dataSource(){
ComboPooledDataSource dataSource = new ComboPooledDataSource();
dataSource.setDriverClass(env.getProperty("db.driverClass"));
dataSource.setJdbcUrl(env.getProperty("db.jdbcUrl"));
dataSource.setUser(env.getProperty("db.user"));
dataSource.setPassword(env.getProperty("db.password"));
dataSource.setMaxPoolSize(50);
dataSource.setMinPoolSize(5);
dataSource.setMaxConnectionAge(1800);
dataSource.setMaxIdleTime(1800);
dataSource.setAutoCommitOnClose(false);
dataSource.setInitialPoolSize(5);
return dataSource;
}
#Bean
public LocalSessionFactoryBean sessionFactory(DataSource dataSource){
LocalSessionFactoryBean localSessionFactoryBean = new LocalSessionFactoryBean();
Properties hibernateProperties = new Properties();
hibernateProperties.setProperty("hibernate.dialect", map.get("db.dialect"));
hibernateProperties.setProperty("hibernate.jdbc.batch_size", "0");
localSessionFactoryBean.setHibernateProperties(hibernateProperties);
localSessionFactoryBean.setDataSource(dataSource);
return localSessionFactoryBean;
}
#Bean
public HibernateTransactionManager transactionManager(SessionFactory sessionFactory){
return new HibernateTransactionManager(sessionFactory);
}
}
Some other related things
Don't catch Exceptions during bean setup, let the configuration blow up else your application is in some weird state.
You are injecting a DataSource into the LocalSessionFactoryBean which makes explicit property settings useless.
The close method of a DataSource is automatically detected.
You don't need all those #Qualifier annotations
Try to be as specific as possible in your return types on #Bean methods, this is needed to have proper callbacks applied.
Don't call afterPropertiesSet yourself Spring will do that for you.

Here is my configuration file

sf.setDataSource(ds());
sf.setHibernateProperties(props());
// sf.setAnnotatedClasses(annotatedClasses);
sf.setPackagesToScan("in.nit.model");
return sf;

//Hibernate properties

}
And this is my Prperties file from which The config would read values
##Connection Properties##
db.driver = oracle.jdbc.driver.OracleDriver
db.url = jdbc:oracle:thin:#localhost:1521:ORCL.168.0.29
db.user = prem
db.password = rempe
##ORM PROPERTIES ##
orm.dialect = org.hibernate.dialect.OracleDialect
orm.show_sql = true
orm.format_sql = true
orm.hbm2ddl.auto = create
##MVC properties##
mvc.prefix = /WEB-INF/views/
mvc.suffix = .jsp
and below is my WebApplicationInitializer file
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class AppInit extends AbstractAnnotationConfigDispatcherServletInitializer {
//provivde root configuration classes to FrontController something like providing web.xml to ServletContainer
#Override

}
#Override
protected Class<?>[] getServletConfigClasses() {
// TODO Auto-generated method stub
return null;
}
//URL pattern
#Override
protected String[] getServletMappings() {
return new String[] {"/"};
}
}
and on running the application in tomcat 9.0 webserver ,I get the following exception

Please Guide me how to resolve this issue and explain why is it occuring?
you are getting null pointer exception because you tried to put null value in property. check props() method and find out whether you are getting not null values from the environment.
hint: issue is with property at line number 57
You are trying to inject property which is not found in your property file
props.put("hibernate.hbm2ddl.auto", env.getProperty("orm.hb2ddl.auto"));
But your property file contains
orm.hbm2ddl.auto = create
I am creating a simple Java Rest API to fetch all records from a table(MySQL db). When I start my application Tomcat 7.0 log say app threw load() exception. Exact error is:
SEVERE: StandardWrapper.Throwable
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerAdapter' defined in org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate `
I have tried changing #Autowire as previously the error was around not finding a bean expected in Autowire. Before that there was Null point Exception due to SessionFactory so I have re-writen to use EntityManager and both these errors are gone.Not able to figure out how this links to my code. I am a newbie trying to reuse existing code to get a hand so pardon any obvious errors please.
Tomcat trace:

All,
I think I figured it out with help from another question here Java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/exc/InvalidDefinitionException
bascially the error was related to
java.lang.ClassNotFoundException: com.fasterxml.jackson.databind.exc.InvalidDefinitionException
and solution was to upgrade my Jackson-databind dependency from 2.8.7 to 2.9.4..
Now I have other exception but thats another story :)
nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]: Factory method 'requestMappingHandlerAdapter' threw exception; nested exception is java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/exc/InvalidDefinitionException
at org.springframework.beans.factory.support.ConstructorResolver.instantiateUsingFactoryMethod(ConstructorResolver.java:587)
This may be with due to
mvc:annotation-driven/> and #EnableWebMvc
both used together, used either one
mvc:annotation-driven /> or #EnableWebMvc to avoid conflict.
I want to read the integer value from the key which I defined in application.properties file. Here is my properties file.
spring.rabbitmq.port=31111
And here is the code:
public Object getPortProperty() {
Properties properties = new Properties();
try {
File file = ResourceUtils.getFile("classpath:application.properties");
InputStream in = new FileInputStream(file);
properties.load(in);
} catch (IOException e) {
}
return (Integer) properties.get("spring.rabbitmq.port");
}
#Autowired
public UnitAmqpRestController(RabbitTemplate rabbitTemplate) throws IOException, TimeoutException {
this.rabbitTemplate = rabbitTemplate;
rabbitTemplate.setReplyTimeout(15_000L);
ConnectionFactory factory = new ConnectionFactory();
factory.setHost(getHostProperty());
factory.setPort((Integer) getPortProperty());
connection = factory.newConnection();
channel = connection.createChannel();
}
Getting the following error:
org.springframework.beans.factory.BeanCreationException: Error

I am not able to understand why it is not working with the integer. if I have a string value, it works perfectly.
please suggest what is wrong in the code
The problematic line of the code is:
factory.setPort((Integer) getPortProperty());
Your code is throwing a NullPointerException and you have an empty catch block. At the bare minimum you should add some logging in there to see what's happening.
Also, you're using Spring and should rarely need to parse application.properties manually; it automatically gets loaded into the application environment.
So you can use #Value to bind it to a local variable instead (same for host property):
#Value("${spring.rabbitmq.port}")
private int mqPort;
#Value("${spring.rabbitmq.host}")
private String mqHost;
#Autowired
public UnitAmqpRestController(RabbitTemplate rabbitTemplate) throws IOException, TimeoutException {
this.rabbitTemplate = rabbitTemplate;
rabbitTemplate.setReplyTimeout(15_000L);
ConnectionFactory factory = new ConnectionFactory();
factory.setHost(mqHost);
factory.setPort(mqPort);
connection = factory.newConnection();
channel = connection.createChannel();
}
Additionally, you should consider using the Spring Boot Rabbit MQ starter module to manage your Rabbit MQ connections and properties instead of managing it yourself.
Having spring.rabbitmq.port=31111 in application.properties or yml, read it using the #Value annotation which reads the property and parses to a correct type:
#Value("${spring.rabbitmq.port=31111}")
private int port;
The class itself should be recognizable as a bean using either #Configuration or any variation of #Component such as #Service.
If you want to load a property using a method as you do, consider using a special method for the integers:
private int getIntegerProperty(final String key, final int defaultValue) {
final Object object = properties.get("spring.rabbitmq.port")
if (object == null || "".equals(object.toString())) {
return defaultValue;
} else {
return Integer.parseInt(object );
}
}
i have a very basic program but no matter what I change in the code I always get the same Error Message:
Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

Read the stacktrace carefully. The cause of your problem is written there.
Caused by: java.util.MissingResourceException: Can't find com.example.demo.QueryRepoImp bundle
This resource-bundle is missing. Check if it is part of your project and recheck. (Or you want to use the LoggerFactory to get a logger instance.)
If you have nested exceptions like this, please check every exception.
I am implementing a JMS client for a RabbitMQ server and I have the following Spring Boot config class.
#Configuration
public class JmsConfig {
private static String EXCHANGE_NAME = "exchange";
#Autowired
private ConnectionFactory connectionFactory;
#Bean
RabbitAdmin rabbitAdmin(ConnectionFactory connectionFactory) {
return new RabbitAdmin(connectionFactory);
}
#Bean
Queue queue(RabbitAdmin rabbitAdmin) {
return rabbitAdmin.declareQueue();
}
#Bean
FanoutExchange exchange() {
return new FanoutExchange(EXCHANGE_NAME);
}
#Bean
Binding binding(Queue queue, FanoutExchange exchange) {
Binding binding = BindingBuilder.bind(queue).to(exchange);
return binding;
}
}
Highlight that in the RabbitMQ server the exchange already exists but the queue connected to the exchange should be created dinamycally by the client(that's the intention) when I run it.
When I start the client app I get the following stacktrace:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'queue' defined in class path resource [com/optimusbet/jms/JmsConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.amqp.core.Queue]: Factory method 'queue' threw exception; nested exception is org.springframework.amqp.UncategorizedAmqpException: java.lang.IllegalStateException: Invalid configuration: 'exchange' must be non-null.

Any ideas of what's going wrong in the initialization? Thanks in advance.
You don't need to declare the queue with the admin - and in fact you should never interact with the broker in a bean definition. The context is not fully baked yet.
You just need...
#Bean
Queue queue() {
return new AnonymousQueue();
}
... you can't use broker-named queues here.
Also, this is not a "JMS" client, it's a RabbitMQ client.
