Answer 1

public class CharFilter implements Filter{ public void destroy() {
// TODO Auto-generated method stub

} public void doFilter(ServletRequest arg0, ServletResponse arg1,
FilterChain arg2) throws IOException, ServletException {
// TODO Auto-generated method stub
arg0.setCharacterEncoding("UTF-8");
arg1.setCharacterEncoding("UTF-8");
arg2.doFilter(arg0, arg1);
} public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub

}

}
上面样写个类下面xml配置
 <filter>
    <filter-name>char</filter-name>
    <filter-class>com.svse.filter.CharFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>char</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

Answer 2

改啦 还是一样报错
严重: Exception starting filter hibernateFilter
java.lang.ClassCastException: org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor
同一个错误

Answer 3

检测一下你是不是有多个版本的Spring jar，servlet.jar 或者 j2ee.jar
