本文介绍了解决Hibernate和JPA中延迟初始化异常的方法。通过配置OpenSessionInViewFilter和SpringOpenEntityManagerInViewFilter过滤器，确保在视图渲染过程中持久化上下文保持打开状态。

<filter>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

<filter>
        <filter-name>SpringOpenEntityManagerInViewFilter</filter-name>
        <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>SpringOpenEntityManagerInViewFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
