初始值设定项：

public class MyWebAppInitializer 
     extends AbstractAnnotationConfigDispatcherServletInitializer { 

    @Override 
    protected Class<?>[] getRootConfigClasses() { 
     return new Class[] { AppConfig.class }; 
    } 

    @Override 
    protected Class<?>[] getServletConfigClasses() { 
     return new Class[] { WebConfig.class }; 
    } 

    @Override 
    protected String[] getServletMappings() { 
     return new String[] { "/" }; 
    } 
}

应用程序配置：

@Configuration 
@PropertySource("classpath:db.properties") 
@EnableTransactionManagement 
@ComponentScans(value = { @ComponentScan("com.boraji.tutorial.spring.dao"), 
     @ComponentScan("com.boraji.tutorial.spring.service") }) 
public class AppConfig { 

    @Autowired 
    private Environment env; 

    @Bean 
    public LocalSessionFactoryBean getSessionFactory() { 
     LocalSessionFactoryBean factoryBean = new LocalSessionFactoryBean(); 

     Properties props = new Properties(); 
     // Setting JDBC properties 
     props.put(DRIVER, env.getProperty("mysql.driver")); 
     props.put(URL, env.getProperty("mysql.url")); 
     props.put(USER, env.getProperty("mysql.user")); 
     props.put(PASS, env.getProperty("mysql.password")); 

     // Setting Hibernate properties 
     props.put(SHOW_SQL, env.getProperty("hibernate.show_sql")); 
     props.put(HBM2DDL_AUTO, env.getProperty("hibernate.hbm2ddl.auto")); 
     props.put(DIALECT, env.getProperty("hibernate.dialect")); 

     // Setting C3P0 properties 
     props.put(C3P0_MIN_SIZE, 
      env.getProperty("hibernate.c3p0.min_size")); 
     props.put(C3P0_MAX_SIZE,

     factoryBean.setHibernateProperties(props); 
     factoryBean.setAnnotatedClasses(User.class); 
     return factoryBean; 
    } 

    @Bean 
    public HibernateTransactionManager getTransactionManager() { 
     HibernateTransactionManager transactionManager = new HibernateTransactionManager(); 
     transactionManager.setSessionFactory(getSessionFactory().getObject()); 
     return transactionManager; 
    } 
}

db.properties：

hibernate.c3p0.max_size=20 
hibernate.c3p0.acquire_increment=1 
hibernate.c3p0.timeout=1800 
hibernate.c3p0.max_statements=150

userDAO的：

@Repository 
public class UserDaoImp implements UserDao { 

    @Autowired 
    private SessionFactory sessionFactory; 


    public void save(User user) { 
     sessionFactory.getCurrentSession().save(user); 
    } 


    public List<User> list() { 
     @SuppressWarnings("unchecked") 
     TypedQuery<User> query = sessionFactory.getCurrentSession().createQuery("from User"); 
     return query.getResultList(); 
    } 

}

我看到很多类似的问题在这里，但它并没有帮助。我的申请中会出现什么问题？

DRIVER，URL，USER和PASS都是静态字段。确保你导入了所有这些。另外，确保你导入了Spring Environment（而不是休眠）。

import static org.hibernate.cfg.Environment.*; 
import org.springframework.core.env.Environment;
