### 1 使用工具开发Struts有两种方式 ###

①用工具引入Struts包和配置文件，然后自己配置Struts-config.xml，完成开发  
②完全依赖MyEclipse提供的工具完成Struts开发

### 2 开发步骤 ###

**①创建web工程**  
**②使用工具导入Struts-config.xml，配置web.xml文件**  
右键该项目，依次点击MyEclipse->Project Facets\[Capabilities\]->Install Apache Struts(1.x) Facet

点击finish，就会自动地引入struts开发包和自动生成struts-config.xml文件，并完成一些配置。  
**③创建相关jsp文件**  
开发简单的登录页面：login.jsp，该jsp依然放在WEB-INF目录下，通过index.jsp转发到该页面。与上篇一样，核心代码如下：

<body>
        <form action="??" method="post">
            UserName:<input type="text" name="username"/><br><br>
            Password:<input type="password" name="password"/><br><br>
            <input type="submit" value="Login"/>    
        </form>
      </body>

**④手动开发ActionForm和Action**  
**⑤手动配置Struts-config.xml**

**⑤在Action中添加业务逻辑**

if("123".equals(userForm.getPassword())) {
    return mapping.findForward("ok");
    } else {
        return mapping.findForward("err");
    }
