Spring+SpringMVC+shiro+mysql（一）

　　最近要做个后台管理系统，就会设计到权限的管理控制，于是就想到 shiro ，下面是自己对Spring+shiro的一点点理解，记录下来，一起多探讨：

项目结构

1. pom.xml 配置

1.1. 版本属性信息配置

7. 缓存文件配置

7.1 ehcache.xml

1 <?xml version="1.0" encoding="UTF-8"?>

3     <diskStore path="java.io.tmpdir" />
4     <!-- DefaultCache setting. -->
5     <defaultCache maxEntriesLocalHeap="10000" eternal="true"
6         timeToIdleSeconds="300" timeToLiveSeconds="600" overflowToDisk="true"
7         maxEntriesLocalDisk="100000" />
8 </ehcache>

7.2 ehcache-shiro.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <ehcache updateCheck="false" name="shiroCache">

12 </ehcache>

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Encoding=utf-8
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
#log4j.appender.CONSOLE.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH:mm:ss} %C{8}@(%F:%L):%m%n
log4j.appender.CONSOLE.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH:mm:ss} %C{1}@(%F:%L):%m%n

log4j.appender.FILE=org.apache.log4j.DailyRollingFileAppender
log4j.appender.FILE.File=${catalina.base}/logs/shiro01.log
log4j.appender.FILE.Encoding=utf-8
log4j.appender.FILE.DatePattern=‘.‘yyyy-MM-dd
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
#log4j.appender.FILE.layout=org.apache.log4j.HTMLLayout
log4j.appender.FILE.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH\:mm\:ss} %C{8}@(%F\:%L)\:%m%n

9. web.xml 配置

  1 <?xml version="1.0" encoding="utf-8"?>
  2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"

再来看看webapp 下文件路径信息吧

我们先来启动一次项目，确保配置信息正确

　　直接点击项目运行maven build 在弹出框输入 tomcat:run apply 后直接运行即可。

如果能正确访问到index.jsp页面，说明之前配置信息没得问题啦
