Answer 1

看看 ThreadLocalSessionContext 和 ManagedSessionContext 类。它应该可以帮助您做您需要的事情。

与 Hibernate 3 几乎相同，但引用了 Hibernate 4 包：

<filter>
                    <filter-name>hibernateFilter</filter-name>
                    <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
                    <init-param>
                            <param-name>singleSession</param-name>
                            <param-value>true</param-value>
                    </init-param>
            </filter>

            <filter-mapping>
                    <filter-name>hibernateFilter</filter-name>
                    <url-pattern>/*</url-pattern>
            </filter-mapping>
