1.Spring中专门提供了处理乱码的问题的解决方案：在web.xml文件中添加下面的过滤器：

<!-- spring中提供的解决乱码问题 -->

<filter>

<filter-name>encoding</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>UTF-8</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>encoding</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

2.spring提供的，hibernate中因session关闭导致的延迟加载例外问题解决方案：同样是将下面的过滤器添加在web.xml文件中

<!--spring提供的解决，hibernate中因session关闭导致的延迟加载例外问题  -->

<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>
