自己在用idea创建struts2时也是遇到一系列迷茫，但是好在最终成功创建。

而最重要在于，jar包和log4j的问题。

# 好了接下来就介绍一下步骤： #

自己的idea版本：2018.3.2；

先把jar包下载好来：

官网：[https://struts.apache.org/download.cgi\#struts2520][https_struts.apache.org_download.cgi_struts2520]

需要下载的jar包：

log4j2下载：

下载地址：[https://archive.apache.org/dist/logging/log4j/2.11.2/][https_archive.apache.org_dist_logging_log4j_2.11.2]

需要下载的内容：

下载好后就可新建项目了：

按照如上所示选择

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NobGVpXw_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NobGVpXw_size_16_color_FFFFFF_t_70 2][]

然后点击Create...导入我们下载好的struts lib中的jar包（红色圈中两个文件是后面下载的log4j，下载第二个就行，这两个文件是我自己加进Struts中的）；然后直接next，填写项目名称即可。

点击finish

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NobGVpXw_size_16_color_FFFFFF_t_70 4][]

进入项目后，我们发现web.xml有报错，这个时候只需要把报错开始的ng删除即可

删除后：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NobGVpXw_size_16_color_FFFFFF_t_70 6][] 之后，点击左上角file → project Structure → problems → \[fix\] → add ‘Struts 2’ to the arctifact → ok

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NobGVpXw_size_16_color_FFFFFF_t_70 8][]

完成后保存：

配置index文件：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
      <title>$Title$</title>
    </head>
    <body>
    <a href="hello.action">点击</a>
    </body>
    </html>

配置struts.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
    
    <!DOCTYPE struts PUBLIC
            "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
            "http://struts.apache.org/dtds/struts-2.5.dtd">
    
    <struts>
        <package name="hello" extends="struts-default">
            <action name="hello">
                <result>hello.jsp</result>
            </action>
        </package>
    </struts>

创建hello.jsp:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
        <title>hello</title>
    </head>
    <body>
    <h1>hello struts 2!</h1>
    </body>
    </html>

运行tomcat效果：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NobGVpXw_size_16_color_FFFFFF_t_70 11][]

最后：希望能帮到大家。
