问题：spring session 异常信息没有打印到日志中
用是默认jdk序列化。由于实体没有序列话，导致异常，但是没有输入到日志，导致定位到问题。

在代码中 request.getSession().setAttribute()是不会出现异常的
spring session 一次请求返回的时候，才会commit,才会触发spring session提交。
代码如下：onResponseCommitted
	
	/**
	 * Allows ensuring that the session is saved if the response is committed.
	 *
	 * @author Rob Winch
	 * @since 1.0
	 */
	private final class SessionRepositoryResponseWrapper
			extends OnCommittedResponseWrapper {

		private final SessionRepositoryRequestWrapper request;

		/**
		 * Create a new {@link SessionRepositoryResponseWrapper}.
		 * @param request the request to be wrapped
		 * @param response the response to be wrapped
		 */
		SessionRepositoryResponseWrapper(SessionRepositoryRequestWrapper request,
				HttpServletResponse response) {
			super(response);
			if (request == null) {
				throw new IllegalArgumentException("request cannot be null");
			}
			this.request = request;
		}

		@Override
		protected void onResponseCommitted() {
			this.request.commitSession();
		}
	}
	
	
OnCommittedResponseWrapper
	
abstract class OnCommittedResponseWrapper extends HttpServletResponseWrapper {
	
		/**
	 * Calls <code>onResponseCommmitted()</code> with the current contents as long as
	 * {@link #disableOnResponseCommitted()} was not invoked.
	 */
	private void doOnResponseCommitted() {
		if (!this.disableOnCommitted) {
			onResponseCommitted();
			disableOnResponseCommitted();
		}
	}
	
}	

doOnResponseCommitted相关依赖出发方法

 

 

解决方法：

filter抓下日志

chain.doFilter(wrappedRequest, response);

 

}catch (Exception ex){

logger.error("xxf",ex);

}
