No CurrentSessionContext configured - java

sorry for bad English. I get my project started with spring-boot 1.1.8, Encountered Exception No CurrentSessionContext configured, then I did some search， add property <property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property> could solve this problem, but
how to config this property using java class?
update: I changed to the Hibernate4.x Way to define SessionFactory but still got the same error, please help!
Use java 1.8 and speing boot 1.1.8
here is my pom.xml
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

Your configuration and usage of hibernate is wrong. You are using Spring and even better Spring Boot, however what you posted tries very hard not to use those frameworks and tries to work around them. I strongly suggest using Spring Boot and let that configure the things for you.
First delete your HibernateUtils, burry it deep and never look at it again. You can also delete your AppConfig as Spring Boot can and will take care of the DataSource.
Next create a file called application.properties in your src/main/resources directory and put the following content in there.
spring.datasource.url=jdbc:mysql://localhost/mysql
spring.datasource.username=root
spring.datasource.password=
This will automatically configure a DataSource for you. You don't need the driver as that is deduced from the url you provide. Next add the following properties to configure JPA.
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext
For more settings and properties I suggest a read of the Spring Boot Reference Guide for the properties check this comprehensive list.
Next in your WebApplicationStarter add the HibernateJpaSessionFactoryBean to expose the created JPA EntityManagerFactory as a SessionFactory.
#Configuration
#EnableAutoConfiguration
#ComponentScan("com.mytest")
public class WebApplicationStarter extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(WebApplicationStarter.class);
}
public static void main(String[] args) throws Exception {
ApplicationContext context = SpringApplication.run(WebApplicationStarter.class, args);
}
#Bean
public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf) {
return hemf.getSessionFactory();
}
}
Then just #Autowire the SessionFactory into your UserServiceImpl.
#Service
#Transactional
public class UserServiceImpl implements UserService {
#Autowired
private SessionFactory sessionFactory;
}
Now you can just use the SessionFactory.

I got this error because I had
sessionFactory.getCurrentSession();
when I changed it to
sessionFactory.openSession();
it worked fine.

So I've been trying to do the example from spring's official guide on connecting Spring with MySQL (https://spring.io/guides/gs/accessing-data-mysql/)
I didn't follow it 100% since I'm using STS for my overall project. The thing is when I use POSTMAN or just my browser to send data
such as :
localhost:8000/demo/add?name=First&email=someemail#someemailprovider.com
I get the error not found.
The java code is the same as in the guide . My application.properties is this:
server.port=8000
spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:mysql://localhost:3306/db_example
spring.datasource.username=springuser
spring.datasource.password=ThePassword
and my pom.xml is this

The answer from my browser is:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing
this as a fallback.

My controller is pretty much identical to the one from spring's guide :
package hello;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import hello.User;
import hello.UserRepository;
#Controller // This means that this class is a Controller
#RequestMapping(path="/demo")
// This means URL's start with /demo (after Application path)
public class UserController {
#Autowired
// This means to get the bean called userRepository
// Which is auto-generated by Spring, we will use it to handle the data
private UserRepository userRepository;
#GetMapping(path="/add") // Map ONLY GET Requests
public #ResponseBody String addNewUser(#RequestParam String name,
#RequestParam String email) {
// #ResponseBody means the returned String is the response,
// not a view name
User n = new User();
n.setName(name);
n.setEmail(email);
userRepository.save(n);
return "Saved";
}
#GetMapping(path="/all")
public #ResponseBody Iterable<User> getAllUsers() {
// This returns a JSON or XML with the users
return userRepository.findAll();
}
}

Your #SpringBootApplication class is in the package com.example.demo (according to the startup log), but your #Controller is in package hello. By default, Spring Boot won't auto-discover Spring classes that are outside the package the #SpringBootApplication class is in. Either move the UserController somewhere under the com.example.demo, or add #ComponentScan annotation targeting your hello package to the main Spring Boot app class.

I have a problem with my new Project , I receive this error that I can not solve, I loaded the project on github I think it's a configuration problem.

stacktrace photo

This exception only came when there is a mismatch of jdbc driver 4 (I think so, I have faced earlier this), As you know hibernate is a ORM tool so to create a connection it needs some meta-data information from the database.
You can disable this feature just by putting this line in application.properties
hibernate.temp.use_jdbc_metadata_defaults = false
if you have hibernate.cfg.xml as a configuration file then you may add this line to your config file
hibernate.cfg.xml file add below property
<property name="hibernate.temp.use_jdbc_metadata_defaults">false</property>
Note :- If you see your application.properties key-value pair must be seperated with = (assignment operator). please add this to your code
Hope this will help you out. Thanks :)

I am trying to build a webapplication using the spring boot initiliazer project option in netbeans 8.2. When I start it up the RUN progress bar hangs after completing the initialization of the dispatcher Servlet. When I try to get a page from the localhost:8080 I get an error returned. I think it has something to do with the dispatcher servlet configuration but i'm not sure, could someone help me please? Below is the output log.

this is the error I see in the browser
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Tue Aug 01 20:32:31 CEST 2017
There was an unexpected error (type=Not Found, status=404).
No message available
thank you
EDIT:
So I've added this to my main class in order to check if the controller gets included in the application context.
#SpringBootApplication
public class SeedcalendarApplication implements ApplicationContextAware {
private static ApplicationContext ac;
public static void main(String[] args) {
SpringApplication.run(SeedcalendarApplication.class, args);
System.out.println("---------------"+ac.containsBean("loginScreenController"));
LoginScreenController log = ac.getBean(LoginScreenController.class);
//for (String i : ac.getBeanDefinitionNames()) System.out.println(i);
}
#Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.ac = applicationContext;
}
}
It outputs FALSE, meaning the logincontroller isent present in the application context, this explains why a get method cannot be found. The next step I took was include the logincontroller as a bean to both Rootconfig and Webconfig classes like so:
#Bean
public LoginScreenController loginScreenController(){
return new LoginScreenController();
}
but i still get a org.springframework.beans.factory.NoSuchBeanDefinitionException when I try to use the getBean() method in the main class! does anyone know why?

the cause of the problem was that the main class and the config classes were in separate packages. Very strange... but problem solved.

I'm using spring boot 1.5.4, i'm following a tutorial where it shows that just by adding h2-console to the localhost:8080/ url you can access the console. But when i do that i have a 404 Whitelabel error.

I have some classes with #Service / #Controller working properly and all the requests are mapped to url strings other than h2-console. Should i import something else in the pom or configure something in application.properties ?

Writing in simple Steps:
In Application.properties file include
spring.h2.console.path=/h2
spring.h2.console.enabled=true
And in pom.xml Include devtools dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
re-package and open http://localhost:[port]/h2 you are all set
other properties you have to include is
spring.datasource.url=jdbc:h2:file:~/h2db
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver
the file h2db will store in userprofile folder of windows
for example : C:\Users\[profile]

I am trying to run Spring boot application but I am facing a problem. Help me please. Why do I have this error?
