架构:
===============================struts2 核心接口和类=========================
名称 作用
ActionMapper 根据请求的URI查找是否存在对应Action调用
ActionMapping 保存调用Action的映射信息,如namespace、name等
ActionProxy 在XWork和真正的Action之间充当代理
ActionInvocation 表示Action的执行状态,保存拦截器、Action实例
Interceptor 在请求处理之前或者之后执行的Struts 2组件
===============================struts2 拦截器=========================
struts2大多数核心功能是通过拦截器实现,每个拦截器完成某项功能,拦截器之间可以互相自由组合
拦截器方法在Action执行之前或执行之后
拦截器栈
1.结构:相当于多个拦截器的组合
2.功能:也是拦截器
与过滤器原理相似
为Action提供附加功能,无须修改Action代码,使用拦截器来提供
三阶段执行周期:
1.Action执行前的预处理
2.将控制交给后续拦截器或者返回字符串(执行Action)
3.Action执行后的处理
范例:
1 public class MyTimeInterceptor extends AbstractInterceptor { 2 /* (non-Javadoc) 3 * @see com.opensymphony.xwork2.interceptor.AbstractInterceptor#intercept(com.opensymphony.xwork2.ActionInvocation) 4 */ 5 @Override 6 public String intercept(ActionInvocation actionInvocation) throws Exception { 7 //预处理工作 8 System.out.println("执行Action之前"); 9 long startTime = System.currentTimeMillis(); 10 11 //执行后续拦截器或Action 12 String result = actionInvocation.invoke(); 13 14 //后续处理工作 15 System.out.println("执行Action之后"); 16 long execTime = System.currentTimeMillis() - startTime; 17 System.out.println("The interval time is "+execTime+" ms"); 18 19 //返回结果字符串 20 return result; 21 } 22 }
拦截器的xml配置:struts.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd" > 3 <struts> 4 <!-- namespace是请求路径 --> 5 <package name="default" namespace="/" extends="struts-default"> 6 7 <!-- 配置拦截器 --> 8 <interceptors> 9 <!-- 定义单个拦截器 --> 10 <interceptor name="myTime" class="com.Elastic.StrutsDemo3.ivy.interceptor.MyTimeInterceptor"></interceptor> 11 <interceptor name="authorization" class="com.Elastic.StrutsDemo3.ivy.interceptor.AuthorizationInterceptor"></interceptor> 12 13 <!-- 自定义拦截器栈 --> 14 <interceptor-stack name="myDefault"> 15 <interceptor-ref name="myTime"></interceptor-ref> 16 <interceptor-ref name="defaultStacks"></interceptor-ref> 17 </interceptor-stack> 18 19 </interceptors> 20 21 <action name="login" class="com.Elastic.StrutsDemo3.ivy.action.UserAction" method="login"> 22 <result name="success" type="redirectAction">index</result> 23 <!-- 引用拦截器 --> 24 <interceptor-ref name="myTime"></interceptor-ref> 25 <!-- 引用Struts默认的拦截器栈。如果用了自定义拦截器,一定要加载struts-default中的defaultStacks --> 26 <interceptor-ref name="defaultStacks"></interceptor-ref> 27 28 <!-- 引用拦截器栈 --> 29 <!-- <interceptor-ref name="myDefault"></interceptor-ref> --> 30 </action> 31 32 </package> 33 </struts>
自带拦截器
1.params拦截器:负责将请求参数设置为Action属性
2.servletConfig拦截器:将源于servlet API的各种对象注入到Action
3.fileUpload拦截器:对文件上传提供支持
4.exception拦截器:捕获异常,并将异常映射到自定义d错误页面
5.validation拦截器:调用验证框架进行数据验证
6.workflow拦截器:调用Action类的validate(),执行数据验证
自定义拦截器:
void init():初始化拦截器所需资源
void destroy():释放在init()中分配的资源
String intercept(ActionInvocation actionInvocation) throws Exception:
1.实现拦截器功能
2.利用ActionInvocation参数获取Action状态
3.返回结果码(result)字符串
继承AbstractInterceptor类
1.提供了init()和destroy()方法的空实现
2.只需要实现intercept方法即可
3.推荐使用
范例:权限验证拦截器
1 public class AuthorizationInterceptor extends AbstractInterceptor { 2 public String intercept(ActionInvocation invocation) throws Exception{ 3 //获取用户会话信息 4 Map session = invocation.getInvocationContext().getSession(); 5 User user = (User)session.get("login"); 6 if (user == null) { 7 //终止执行,返回登录页面 8 return Action.LOGIN; 9 } else { 10 //继续执行剩余的拦截器和Action 11 return invocation.invoke(); 12 } 13 } 14 }
===================================文件上传下载==========================
一、文件上传
Commons-FileUpload组件
Commons是Apache开放源代码组织的一个Java子项目,其中的FileUpload是用来处理HTTP文件上传的子项目
特点:
a.使用简单:可以方便地嵌入到JSP文件中,编写少量代码即可完成文件的上传功能
b.能够全程控制上传内容
c.能够对上传文件的大小、类型进行控制
环境要求:commons-fileupload-xxx.jar commons-io-xxx.jar(在 struts2 的jar包中查找)
范例:
1 public class UploadAction extends ActionSupport { 2 private File upload; 3 private String uploadContentType; 4 private String uploadFileName; 5 private String savePath; 6 //…省略set和get方法 7 public String execute() throws Exception { 8 FileInputStream fis=new FileInputStream(getUpload()); 9 FileOutputStream fos=new FileOutputStream(getSavePath()+"\\”+this.getUploadFileName()); 10 } 11 }
1 <s:form action="upload.action" enctype="multipart/form-data" method="post"> 2 <s:file name="upload" label="选择文件"/> 3 </s:form> 4 5 <action name="upload" class="com.xuetang9.demo.action.UploadAction"> 6 <!--通过param参数设置保存目录的路径--> 7 <param name="savePath">/upload</param> 8 <result name="success">/upload_success.jsp</result> 9 </action>
多文件上传
【name属性相同】
将三个属性的类型修改成数组类型
//获取提交的多个文件
private File[] upload;
//封装上传文件的类型
private String[] uploadContentType;
//封装上传文件名称
private String[] uploadFileName;
二、文件下载
stream结果类型
1.将文件数据(通过InputStream获取)直接写入响应流
2.相关参数的配置
名称 作用
contentType 设置发送到浏览器的MIME类型
contentLength 设置文件的大小
contentDisposition 设置响应的HTTP头信息中的Content-Disposition参数的值(一方面表示文件的处理方式,另一方面指定下载文件的显示文件名称)
inputName 指定Action中提供的inputStream类型的属性名称
bufferSize 设置读取和下载文件时的缓冲区大小
contentType:指定文件下载的类型
文件类型 类型设置
Word application/msword
Execl application/vnd.ms-excel
PPT application/vnd.ms-powerpoint
图片 image/gif , image/bmp,image/jpeg
文本文件 text/plain
html网页 text/html
可执行文件 application/octet-stream
范例:
1 public class FileDownAction extends ActionSupport { 2 //读取下载文件的目录 3 private String inputPath; 4 //下载文件的文件名 5 private String fileName; 6 //下载文件的类型 7 private String conetntType; 8 //创建InputStream输入流 9 public InputStream getInputStream() throws FileNotFoundException{ 10 String path=ServletActionContext.getServletContext().getRealPath(inputPath); 11 return new BufferedInputStream(new FileInputStream(path+"\\"+fileName)); 12 } 13 }
1 <action name="download" class="com.xuetang9.demo.action.FileDownAction"> 2 <param name="inputPath">/upload</param> 3 4 <!-- 指定类型为stream --> 5 <result name="success" type="stream"> 6 7 <!-- 通用设置 --> 8 <param name="contentType">application/octet-stream</param> 9 <param name="inputName">inputStream</param> 10 <param name="contentDisposition"> 11 <!-- 12 attachement表示以附件形式下载 13 filename表示下载时显示的文件名称 14 --> 15 attachment;filename="${fileName}" 16 </param> 17 <param name="bufferSize">4096</param> 18 </result> 19 </action>
只有首页用,清除session内容
