我的Web应用程序在Spring 4.x和Hibernate上运行。当8次调用服务后，我的代码执行中断并发呼叫
代码片段数据库配置：
@SuppressWarnings("unused")
@Configuration
@EnableTransactionManagement
//@EnableJpaRepositories("com.pearson.esp.dao")
public class DbConfiguration {
private static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
private static final String PROPERTY_NAME_DATABASE_PASSWORD = "db.password";
private static final String PROPERTY_NAME_DATABASE_URL = "db.url";
private static final String PROPERTY_NAME_DATABASE_USERNAME = "db.username";
private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";
private static final String PROPERTY_NAME_HIBERNATE_CONNECTION_RELEASE_MODE = "hibernate.connection.release_mode";
//private static final String PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN = "entitymanager.packages.to.scan";
@Resource
private Environment env;
@Bean
public DataSource dataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
dataSource.setUrl(env.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
dataSource.setUsername(env.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
dataSource.setPassword(env.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));
return dataSource;
}
@Bean
@Autowired
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan(new String[] { "com.pearson.esp" });
sessionFactory.setHibernateProperties(hibProperties());
return sessionFactory;
}
@Bean
@Autowired
public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) {
HibernateTransactionManager tm = new HibernateTransactionManager();
tm.setDefaultTimeout(30);
tm.setSessionFactory(sessionFactory);
return tm;
}
private Properties hibProperties() {
Properties properties = new Properties();
properties.put(PROPERTY_NAME_HIBERNATE_DIALECT, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
//properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, "true");
properties.put(PROPERTY_NAME_HIBERNATE_CONNECTION_RELEASE_MODE, "after_transaction");
return properties;
}
}
此代码执行休息时尝试8次后调用服务同时在调用。例外情况是：
org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web application [esp-webservice] is still processing a request that has yet to finish. This is very likely to create a memory leak. You can control the time allowed for requests to finish by using the unloadDelay attribute of the standard Context implementation.
