idea+maven + spring security +springmvc入门（自定义登录页面），附idea如何创建web项目

第一次使用idea，上午在eclipse中学习了spring security 入门，下午试试在idea中搭建。

刚开始我以为直接将eclipse的文件 copy过来就行了，结果发现copy过来以后各种报错。

后来把maven本地仓库jar包都删了，并在setting文件中配置了阿里云镜像，就好了。

然后就是在 eclipse中运行正常的 springmvc.xml,头信息开始报错。找了很久头信息，最终终于找到可以使用的版本。

如果你想看eclipse版本的 spring security +springmvc入门

请看我上一篇文章点击打开链接

一：点击Create New Project

二：点Maven 选 JDK ，勾Create from archetype ，在下面选 webapp结尾的。

三：输入GroupId和ArtifactId

GroupId是项目组名

ArtifactId是项目名

四：选maven位置，setting文件位置，maven本地仓库位置。

注意：如果不用默认的setting文件位置和maven本地仓库位置，必须要勾选上override。

setting里面最好配置上阿里云的镜像，这样下载jar会比较快，官方的maven中心仓库下载的慢，容易jar包下残导致不能使用。

如果你以前用过eclipse，本地仓库自己最好再建一个文件夹，别和eclipse共用一个本地仓库。我怕冲突。

<mirror>
<id>alimaven </id>
<name>aliyun maven </name>
<url>http://maven.aliyun.com/nexus/content/groups/public/ </url>
<mirrorOf>central </mirrorOf>
</mirror>

五：起项目名和项目位置，不用改

六：进入以后如下图所示，如果你没有这些工具栏，可以点击View，然后开启，同时看一下项目结构

七：建文件夹 -- 右键 main -->new -->directory-->起名为 java

然后右键 java --Mark Directory As --Source Root (意思就是你的java代码在这下面写) 点完以后java文件夹变蓝色了。

然后右键java -- new --package 起名如com.zzh.controller

然后再右键 main 创建个 resource文件夹。右键resource这个文件夹，还是Makr Directory as --> Resources Root

最终项目结构如下

八：配置tomcat

点进去以后左上角有个绿色的加号，然后点最下面那个，将列表显示完全，然后选择tomcatserver - local（如果没有tomcat，需要先安装tomcat插件，这个自己上网搜吧，我懒得写了）

准备工作完成，下面进入spring service和 spring mvc 部分。

首先按照我的项目结构，去添加各种文件，下面列出文件内容。

以上为文件内容。

下面开始配置项目信息

选择 Modules ， Project不用管。选择Dependencies 添加Tomcat Library

同时检查文件类型以及 Artifacts是否已经自动配置好

出现如上2图所示就没问题了。

最后在tomcat中部署项目。选择文件夹形式发布即 exploded 结尾的。

运行项目

效果展示 index页面

spring security 实现效果输入/admin，自己冲定向到登录页面

注意看右面的network

用户名密码输入正确(有权限的用户) 会进入我们原本请求的 RequestMapping对应的方法

点击注销回到登录页面

如果你按照我的步骤成功了，帮忙点个赞，写这么久真心累。支持一下。或者遇到什么问题，可以留言，或许可以帮你解决。
