cookie设置日期时间有空格报错：java.lang.IllegalArgumentException: An invalid character [32] was present in the Cookie value

创建时间:6.30 java.lang.IllegalArgumentException: An invalid character [32] was present in the Cookie value 报错原因: Tomcat 8.5版本,在cookie值中不能使用空格. 代码: 1 protected void doGet(HttpServletRequest request, HttpServletResponse response) 2 throws ServletException

今天在练习 cookie时意外的报了这个错. java.lang.IllegalArgumentException: An invalid character [32] was present in the Cookie value1这句话的意思是 一个不识别的字符[32]出现在了cookie当中 由于tomcat的版本比较高,所以在addCookie时是不能使用空格的 而在ASCII码中32对应的就是空格.只要把后台代码中的空格删掉就可以了. 我的代码:是在cookie中添加了时间,而时间的格

HTTP Status 500 – Internal Server Error Type Exception Report Message An invalid character [32] was present in the Cookie value Description The server encountered an unexpected condition that prevented it from fulfilling the request. Exception java.l

class Person{ private String name ; private String sex ; public Person(){ System.out.println("c"); } public Person(String c1){ this.name =c1; System.out.println("c1"+c1); } public Person(String c1,String c2){ this.name =c1; this.sex =c

启动tomcat的时候报如下错误: java.lang.IllegalArgumentException: Document base F:\java\tools\tomcat\me-webapps\drp1.1 does not exist or is not a readable directory     at org.apache.naming.resources.FileDirContext.setDocBase(FileDirContext.java:142)    at org.a

1. 问题描述 Servlet中执行下面一段代码: public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html;charset=utf-8"); System.out.println( new Date().toString()); Cookie c

原因及解决办法:https://docs.spring.io/spring-boot/docs/2.0.3.RELEASE/reference/htmlsingle/#howto-use-tomcat-legacycookieprocessor @Configuration public class CookieConfig { /** * 解决问题: * There was an unexpected error (type=Internal Server Error, status=500)

仔细检查发现是<%@ page import=" java.util.*;"%>一句引起的错误. 把<%@ page import=" java.util.*;"%>中的分号去掉就好了,改为: <%@ page import=" java.util.*"%> 所以以后写import要规范. 项目中可能还有多处这种问题,大部分情况是开发人员写代码太随意的原因.

原因是在使用<if> 进行条件判断时, 将datetime类型的字段与 ' ' 进行了判断,导致的错误 解决, 只使用  <if test="createTime != null"></if> 做判断就行了 详细可参考: https://blog.csdn.net/wanghailong_qd/article/details/50673144 原文地址:https://www.cnblogs.com/gczmn/p/11880972.html
