javaWeb学习总结（10）- Filter(过滤器)学习

一、Filter简介

　　Filter也称之为过滤器，它是Servlet技术中最激动人心的技术，WEB开发人员通过Filter技术，对web服务器管理的所有 web资源：例如Jsp, Servlet, 静态图片文件或静态 html 文件等进行拦截，从而实现一些特殊的功能。例如实现URL级别的权限访问控制、过滤敏感词汇、压缩响应信息等一些高级功能。
　　Servlet
API中提供了一个Filter接口，开发web应用时，如果编写的Java类实现了这个接口，则把这个java类称之为过滤器Filter。通过
Filter技术，开发人员可以实现用户在访问某个目标资源之前，对访问的请求和响应进行拦截，如下所示：

　　

二、Filter是如何实现拦截的？

　　Filter接口中有一个doFilter方法，当我们编写好Filter，并配置对哪个web资源进行拦截后，WEB服务器每次在调用web
资源的service方法之前，都会先调用一下filter的doFilter方法，因此，在该方法内编写代码可达到如下目的：

1. 调用目标资源之前，让一段代码执行。
2. 是否调用目标资源（即是否让用户访问web资源）。
3. 调用目标资源之后，让一段代码执行。

　　web服务器在调用doFilter方法时，会传递一个filterChain对象进来，filterChain对象是filter接口中最重
要的一个对
象，它也提供了一个doFilter方法，开发人员可以根据需求决定是否调用此方法，调用该方法，则web服务器就会调用web资源的service方
法，即web资源就会被访问，否则web资源不会被访问。

三、Filter开发入门

3.1、Filter开发步骤

　　Filter开发分为二个步骤：

1. 编写java类实现Filter接口，并实现其doFilter方法。
2. 在 web.xml 文件中使用<filter>和<filter-mapping>元素对编写的filter类进行注册，并设置它所能拦截的资源。

　　过滤器范例：

package me.gacl.web.filter;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

/**
* @ClassName: FilterDemo01
* @Description:filter的三种典型应用：
*                     1、可以在filter中根据条件决定是否调用chain.doFilter(request, response)方法，
*                        即是否让目标资源执行
*                     2、在让目标资源执行之前，可以对request\response作预处理，再让目标资源执行
*                     3、在目标资源执行之后，可以捕获目标资源的执行结果，从而实现一些特殊的功能

public class FilterDemo01 implements Filter {

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        System.out.println("----过滤器初始化----");
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {

        //对request和response进行一些预处理
        request.setCharacterEncoding("UTF-8");
        response.setCharacterEncoding("UTF-8");
        response.setContentType("text/html;charset=UTF-8");

        System.out.println("FilterDemo01执行前！！！");
        chain.doFilter(request, response);  //让目标资源执行，放行
        System.out.println("FilterDemo01执行后！！！");
    }

    @Override
    public void destroy() {
        System.out.println("----过滤器销毁----");
    }
}

在web. xml中配置过滤器：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name></display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

  <!--配置过滤器-->
  <filter>
      <filter-name>FilterDemo01</filter-name>
      <filter-class>me.gacl.web.filter.FilterDemo01</filter-class>
  </filter>

  <!--映射过滤器-->
  <filter-mapping>
      <filter-name>FilterDemo01</filter-name>
      <!--“/*”表示拦截所有的请求 -->
      <url-pattern>/*</url-pattern>
  </filter-mapping>

</web-app>

启动web服务时候调用init方法

3.2、Filter链

　　在一个web应用中，可以开发编写多个Filter，这些Filter组合起来称之为一个Filter链。
　　web服务器根据
Filter在web.xml文件中的注册顺序，决定先调用哪个Filter，当第一个Filter的doFilter方法被调用时，web服务器会创建
一个代表Filter链的FilterChain对象传递给该方法。在doFilter方法中，开发人员如果调用了FilterChain对象的
doFilter方法，则web服务器会检查FilterChain对象中是否还有filter，如果有，则调用第2个filter，如果没有，则调用目
标资源。

四、Filter的生命周期

4.1、Filter的创建

　　Filter的创建和销毁由WEB服务器负责。 web 应用程序启动时，web 服务器将创建Filter 的实例对象，并调用其init方法，完成对象的初始化功能，从而为后续的用户请求作好拦截的准备工作，filter对象只会创建一次，init方法也只会执行一次。通过init方法的参数，可获得代表当前filter配置信息的FilterConfig对象。

4.2、Filter的销毁

　　Web容器调用destroy方法销毁Filter。destroy方法在Filter的生命周期中仅执行一次。在destroy方法中，可以释放过滤器使用的资源。

4.3、FilterConfig接口

　　用户在配置filter时，可以使用<init-param>为filter配置一些初始化参数，当web容器实例化Filter
对象，调用其init方法时，会把封装了filter初始化参数的filterConfig对象传递进来。因此开发人员在编写filter时，通过
filterConfig对象的方法，就可获得：
　　String getFilterName()：得到filter的名称。
　　String getInitParameter(String name)： 返回在部署描述中指定名称的初始化参数的值。如果不存在返回null.
　　Enumeration getInitParameterNames()：返回过滤器的所有初始化参数的名字的枚举集合。
　　public ServletContext getServletContext()：返回Servlet上下文对象的引用。
范例：利用FilterConfig得到filter配置信息

package me.gacl.web.filter;

import java.io.IOException;

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        System.out.println("----过滤器初始化----");
        /**

         */
        //得到过滤器的名字
        String filterName = filterConfig.getFilterName();
        //得到在web.xml文件中配置的初始化参数
        String initParam1 = filterConfig.getInitParameter("name");
        String initParam2 = filterConfig.getInitParameter("like");
        //返回过滤器的所有初始化参数的名字的枚举集合。
        Enumeration<String> initParameterNames = filterConfig.getInitParameterNames();

        System.out.println(filterName);
        System.out.println(initParam1);
        System.out.println(initParam2);
        while (initParameterNames.hasMoreElements()) {
            String paramName = (String) initParameterNames.nextElement();
            System.out.println(paramName);
        }
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {
        System.out.println("FilterDemo02执行前！！！");
        chain.doFilter(request, response);  //让目标资源执行，放行
        System.out.println("FilterDemo02执行后！！！");
    }

    @Override
    public void destroy() {
        System.out.println("----过滤器销毁----");
    }
}

五、Filter的部署

　　Filter的部署分为两个步骤：

　　1、注册Filter

　　2、映射Filter

5.1、注册Filter

　　开发好Filter之后，需要在web.xml文件中进行注册，这样才能够被web服务器调用

　　在web.xml文件中注册Filter范例：

<filter>
          <description>FilterDemo02过滤器</description>
          <filter-name>FilterDemo02</filter-name>
          <filter-class>me.gacl.web.filter.FilterDemo02</filter-class>
          <!--配置FilterDemo02过滤器的初始化参数-->
          <init-param>
              <description>配置FilterDemo02过滤器的初始化参数</description>
              <param-name>name</param-name>
              <param-value>gacl</param-value>
          </init-param>
          <init-param>
              <description>配置FilterDemo02过滤器的初始化参数</description>
              <param-name>like</param-name>
              <param-value>java</param-value>
          </init-param>
</filter>

<description>用于添加描述信息，该元素的内容可为空，<description>可以不配置。

　　<filter-name>用于为过滤器指定一个名字，该元素的内容不能为空。
　　<filter-class>元素用于指定过滤器的完整的限定类名。
　
　<init-param>元素用于为过滤器指定初始化参数，它的子元素<param-name>指定参数的名
字，<param-value>指定参数的值。在过滤器中，可以使用FilterConfig接口对象来访问初始化参数。如果过滤器不需要指
定初始化参数，那么<init-param>元素可以不配置。

5.2、映射Filter

　　在web.xml文件中注册了Filter之后，还要在web.xml文件中映射Filter

<!--映射过滤器-->
  <filter-mapping>
      <filter-name>FilterDemo02</filter-name>
      <!--“/*”表示拦截所有的请求 -->
      <url-pattern>/*</url-pattern>
  </filter-mapping>

<filter-mapping>元素用于设置一个 Filter 所负责拦截的资源。一个Filter拦截的资源可通过两种方式来指定：Servlet 名称和资源访问的请求路径
　　<filter-name>子元素用于设置filter的注册名称。该值必须是在<filter>元素中声明过的过滤器的名字
　　<url-pattern>设置 filter 所拦截的请求路径(过滤器关联的URL样式)
　　<servlet-name>指定过滤器所拦截的Servlet名称。
　
　<dispatcher>指定过滤器所拦截的资源被 Servlet
容器调用的方式，可以是REQUEST,INCLUDE,FORWARD和ERROR之一，默认REQUEST。用户可以设置多
个<dispatcher> 子元素用来指定 Filter 对资源的多种调用方式进行拦截。如下：

<filter-mapping>
    <filter-name>testFilter</filter-name>
   <url-pattern>/index.jsp</url-pattern>
   <dispatcher>REQUEST</dispatcher>
   <dispatcher>FORWARD</dispatcher>
</filter-mapping>

<dispatcher> 子元素可以设置的值及其意义：

1. REQUEST：当用户直接访问页面时，Web容器将会调用过滤器。如果目标资源是通过RequestDispatcher的include()或forward()方法访问时，那么该过滤器就不会被调用。
2. INCLUDE：如果目标资源是通过RequestDispatcher的include()方法访问时，那么该过滤器将被调用。除此之外，该过滤器不会被调用。
3. FORWARD：如果目标资源是通过RequestDispatcher的forward()方法访问时，那么该过滤器将被调用，除此之外，该过滤器不会被调用。
4. ERROR：如果目标资源是通过声明式异常处理机制调用时，那么该过滤器将被调用。除此之外，过滤器不会被调用。
