example spring-boot sessionfactory

spring-boot - example - spring boot inject hibernate session



No CurrentSessionContext configurado (1)

Su configuración y uso de hibernación es incorrecta. Está utilizando Spring e incluso mejor Spring Boot, sin embargo, lo que ha publicado trata de no usar esos frameworks y trata de evitarlos. Sugiero usar Spring Boot y dejar que configure las cosas por ti.

Primero borre sus HibernateUtils , entiérrelo y nunca lo vuelva a mirar. También puede eliminar su AppConfig ya que Spring Boot puede y se hará cargo de DataSource .

A continuación, cree un archivo llamado application.properties en su directorio src/main/resources y coloque el siguiente contenido allí.

spring.datasource.url=jdbc:mysql://localhost/mysql spring.datasource.username=root spring.datasource.password=

Esto configurará automáticamente un DataSource para usted. No necesita el controlador como se deduce de la url que proporciona. A continuación, agregue las siguientes propiedades para configurar JPA.

spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

Para obtener más configuraciones y propiedades, sugiero leer la Guía de referencia de Spring Boot para ver las propiedades de esta lista completa .

Luego, en su WebApplicationStarter agregue HibernateJpaSessionFactoryBean para exponer el JPA EntityManagerFactory creado como 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(); } }

Luego simplemente @Autowire the SessionFactory en su UserServiceImpl .

@Service @Transactional public class UserServiceImpl implements UserService { @Autowired private SessionFactory sessionFactory; }

Ahora solo puede usar SessionFactory .

perdón por mal inglés. Comienzo mi proyecto con spring-boot 1.1.8 , Excepción Encuentro No CurrentSessionContext configured , luego hice una búsqueda, <property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property> propiedad <property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property> podría resolver este problema, pero

cómo configurar esta propiedad usando la clase java?

actualización: Cambié a la forma Hibernate4.x de definir SessionFactory pero aún tengo el mismo error, ¡por favor ayuda!

Usa java 1.8 y speing boot 1.1.8

aquí está mi pom.xml

<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <java.version>1.8</java.version> <main.basedir>${basedir}/../..</main.basedir> <m2eclipse.wtp.contextRoot>../</m2eclipse.wtp.contextRoot> </properties> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>1.1.8.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency>

aquí está mi Servicio y Controlador

@AutoWried SessionFactory sessionFactory; @Service @Transactional public class UserServiceImpl implements UserService { public boolean isEmailExist(String email) { Session session = sessionFactory.openSession(); // if I use getCurrentSession(), I will got the No Session found for current thread //Session session = sessionFactory.getCurrentSession(); Criteria c = UserCriteria.isEmailExisting(session, email); List<UserInfo> usrs = c.list(); session.close(); if (0 == usrs.size() || usrs.isEmpty()) return false; return true; } } @Controller public class UserRegisterController { @Autowired UserService userService; @RequestMapping("/doRegist") public void doRegister(HttpServletRequest request, HttpServletResponse response) { String usrEmail = request.getParameter("email"); boolean exist = userService.isEmailExist(session, usrEmail); //todo } }

WebApplicatoinStarter.java

@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(); } }
