1、loadFilterChainDefinitions方法有时突然执行，除了项目启动时执行一次加载shiro_base_auth文件之外，还有那个入口会执行loadFilterChainDefinitions方法呢？
2、执行报如下错：
"ContainerBackgroundProcessor[StandardEngine[Catalina]]" java.lang.OutOfMemoryError: PermGen space？这是什么原因呢

redis 也配置好了，数据库也初始化了，启动也是没问题的。应用直接部署在ROOT下。但是，浏览器访问 http://localhost:8080/ 的时候， Tomcat就出错， 然后自动stop 了， 好奇怪啊。 有谁遇到过吗？ 或者我配置哪里错了？

您好。我用mybatis genertor 生成的model 和xml放到你的项目启动报错。请问您的mapper.xml是手写的吗。我看您是自己封装的分页。

ftl文件用什么html格式还是jsp页面格式打开呢，两种方式打开index.ftl文件时so.default和/@shiro.hasPermission <@shiro.hasPermission name="/permission/addPermission.shtml"> <#--添加权限-->eclipse会报红

[org.apache.shiro.realm.AuthenticatingRealm]AuthenticationInfo caching is disabled for info

就这个cache一直报空,

在修改用户名信息比如昵称的时候，页面不会动态更新，而是要等下次登陆才会更新。

在用户进行登陆的时候，如果抛出异常信息，会提示用户的账户或者密码错误，其实用的账户密码均正确，但是异常处理中 却更改了 将 map中的状态改编成了 500，原来的200 就失效了。这样的提示不是很好，一个exception 太笼统。具体的代码是
package com.sojson.user.controller;中的UserLoginController 189-193代码行，一直提示用户名或密码错误，但是打断点，数据没有错误，由于自己添加的测试信息抛出了异常，才导致的错误。

运行系统后无效的Session不会删除，Session数目越来越多

redis缓存能用集群吗？

获取总数哪里会报错，链接是关闭的
connection holder is null

conn 使用这个代替
SqlSessionTemplate st = (SqlSessionTemplate) getSqlSession();
Connection conn = SqlSessionUtils.getSqlSession(
st.getSqlSessionFactory(), st.getExecutorType(),
st.getPersistenceExceptionTranslator()).getConnection();

网站没备案里面的好多文件也获取失败了

1. pom文件并没有把maven所需要的plugins插件依赖加进去。
2. pom文件并没有把resources下的文件引入进去
3. redis启动需要把参数加进去，而且你的redis配置文件需要改成redis.conf，而不是redis.window.conf
4. 数据库脚本导入不对，你可以把readMe重新写一下
5. 我遇到的问题是tomcat日志输出不了，解决方案是在web-inf/classes下面新建logging.properties,填入如下内容：handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

IntrospectorCleanupListener应该注册为web.xml中的第一个Listener，在任何其他Listener之前注册，比如在Spring's ContextLoaderListener注册之前，才能确保IntrospectorCleanupListener在Web应用的生命周期适当时机生效。

1这个项目中用到了session ,默认情况下 session 在集群下是会出错 的 ，这里是否还需自己处理 session集群的问题

2 有时候点击退出登陆会提示退出失败 ，看了一下 是loginfiler 返回了 用户未登陆并且是Ajax 请求，如果是未登录 我刷新页面应该跳转到登陆页 实际并没有

在页面最低端的分页，为什么要这么做呢？把显示写在了代码里面，这。。。。。。。。。。。。。。
我该怎么说呢，怎么会想到这么写呢？

IDE的环境配置文件不需要把。

pom.xml里jackson-databind jackson-core和jackson-annotations版本不同导致编译错误

我把jackson-databind改回2.7.4后正常运行

在同一个浏览器中打开两个登录页面,先登录一个admin ,然后在登录一个用户,再去刷新admin的页面时,会发现已经变成了第二个登录的用户信息了,这个有没有什么好一点的办法解决一下呢

1. 用户的修改个人资料，虽然数据库中显示已经修改成功，但是页面显示还是旧数据
   2.楼主那个json的问题还没有解答
   3。暂时没找到

CREATE TABLE u_role (
id bigint(20) NOT NULL AUTO_INCREMENT,
name varchar(32) DEFAULT NULL COMMENT '角色名称',
type varchar(10) DEFAULT NULL COMMENT '角色类型',
PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

1. pom.xml 中没有标明 都是什么包，或者说不友好
   2.为什么要和tomcat绑在一起，jdk也设定好了，无语
   3.shiro中自己定义了过滤器，但是你没有正确的引用kickout，看看bean的名称就知道了。

我尝试着用eclipse直接import archive file，但是eclipse提示我这个archive file并不是open project。看文件夹得名字我相信这个东西应该是从某个IDE中export出来的，但是为什么我import不了呢。。。。。

UserLoginController类中的submitLogin(UUser, Boolean, HttpServletRequest) 在使用 UUser的时候怎么没有添加@requestbody 注解呢？ 不明白。。。。。

问题一: redis中都加载了什么数据，我看到的数据很奇怪。

问题二 ：还有请教一个没解决的问题，我想要看一下shiro的源码，maven已经下载了相关的源码，但是并没有加载。这样的问题只是存在shiro中，其他的框架都正常加载源码。不知道你能加载源码么？
