字节输出流和字符输出流的共存问题
结论：不能共存(跟get或post方式没关系)。即在同一个servlet中字符流与字节流不能共存，两种方法单独使用都是可以的
另外：如果要用字节流输出中文，用write(byte[])方法，因为它的out.print(“晚上好!”);//500错误。内部用iso8859-1读取，已经写死了，因此中文不行
转发时，两个servlet都输出信息的问题
转发用
<code class="hljs vbscript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"> RequestDispatcher rd = <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">request</span>.getRequestDispatcher(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"/servlet/TwoServlet"</span>); rd.forward(<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">request</span>, <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">response</span>);</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>
Tomcat对于同response，只输出一次(把缓存中的内容刷出去)。刷了(close也一样)，流就关闭了,下面的转发就无法进行了，因为此时response已经提交了(整个转发链只会响应一次，即提交了) .
详细知识点见转发的第三点。
重定向 传参 访问顺序（doget还是dopost）
重定向用response.sendRedirect("/servletDemo4/servlet/Redir2Servlet"); 参数带项目名，因为发给浏览器要在tomcat目录下。
在重定向第一个servlet输出会被第二个servlet输出覆盖，其实是输出了，但是跳转的时间太快，人眼不可见。
无论第一个servlet是doget还是dopost，第二个servlet都是doget。因为转发过去直接在地址栏输入路径，不会在生成表单设置post
重定向，第二个servlet和第一个servlet的request和response都不是同一个对象了，因此无法通过request.setAttribute("age", 22); 和request.getAttribute("age");传参，并且，第二个servlet也无法通过request.getParameter("name");从页面获取参数。
重定向情况下，如要传参，则采用地址栏的url的？后面加key=value，多个用&连接。
采用地址栏传参的方式，在浏览器地址栏能看到参数值，因此要注意隐私问题—–加密
转发只能在站内进行（路径默认在项目内）而重定向可以在站外进行（如果是在站外，路径要带”http://”开头，站内要带项目名）如果非要在项目之间（站外）进行跳转，则必须采用重定向。
转发 传参 访问顺序（doget还是dopost）
第一个servlet用dopost第二个servlet也用dopost。第一个servlet用doget第二个servlet也用doget。
第二个servlet中的response会把缓存清空，即将上个servlet的内容清空，然后将此时的servlet的内容写入缓存，刷出去，显示到页面。
tomcat对于同一个servlet只输出一次（把缓存中的内容刷出去）如果第一个servlet刷了，流就关闭了。只会对response操作会出异常，因为此时的response已经提交，不能再转发了。
为解决上面的问题，我们用传参在第一个servlet中用request.setAttribute("age", 22);第二个servlet中用request.getAttribute("age"); 通过request容器来进行读写，因为转发其实是共享同一个request和同一个response对象。在转发过程中，servlet可以对request进行多次读取参数。
请求包含 传参 访问顺序（doget还是dopost）
请求包含用
<code class="hljs vbscript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"> RequestDispatcher rd = <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">request</span>.getRequestDispatcher(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"/servlet/Include2Servlet"</span>); rd.include(<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">request</span>, <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">response</span>);</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>
请求包含的机制可以理解成函数调用，相当于把第二个servlet 中的代码拷到这里来执行。
第一个servlet用doget第二个servlet用doget；第一个servlet用dopost第二个servlet也用dopost。
对于请求包含，第二个servlet在执行完之后还会回到第一个servlet的rd.include(request,
response);
之后。
请求包含与转发传参一样，也是共享同一个request和同一个response对象。不同的是，在请求包含中，如在第一个servlet关流，后面不会出异常，只是后面的不会执行了。如在第一个servlet刷即用out.flush();流不会关闭。请求包含我个人可以理解成是同一个servlet，只是包含的servlet是一个功能模块而已，所以在同一个servlet中，刷(flush)没有影响，实质还是在同一个servlet中。

知识点：
1字节输出流和字符输出流的共存问题
结论：在一个servlet中字符流与字节流不能共存，两种方法单独使用都是可以的
2转发时，两个servlet都输出信息的问题
正常的后面一个会覆盖前面，具体的可以看4.2和4.3
3重定向 传参 访问顺序（doGet还是doPost ）
1>方法是：response.sendRedirect() 因为转发给浏览器，要在tomcat目录下参数要带项目名
2>在重定向第一个servlet输出后会被第二个servlet输出覆盖，其实是输出了，但是跳转时间太快，人眼不可见
3>无论第一个servlet是dopost还是doget，第二个servlet都是doget，因为转发过去直接在地址栏输入路径。不会再生成表单设置post
4>重定向第二个servlet和第一个servlet的request和response不是同一个对象，无法用过serAttribute和getAttribute传参，第二个servlet无法通过getParamer从页面获取参数
5>如要传参，采用地址栏的url的？后面加key=value 形式进行传参，多个用&连接。采用地址栏传参方式
在浏览器地址栏可以看到所传的参数，因此要注意隐私问题----加密
6>转发只能在站内进行（路径默认在项目内）而重定向可以在站外进行（如果在站外，路径要带"http://"开头，站内要带项目名）
如果非要在项目之间（站外）进行跳转，不虚采用重定向
4转发 传参 访问顺序（doGet还是doPost ）
1>转发:第一个servlet用doget第二个就是用doget；第一个用dopost第二个也用dopost；
2>第二个servlet中的response会先把缓存清空，然后将此时的servlet的内容写到缓存，刷出去显示到页面
3>tomcat对同一个response只会输出一次，如果第一个servlet刷了即out.flush()
那么流在此就关闭了，后面转发，操作response都会出异常。因为此时的response已经提交，不能再转发了
4>为了解决上面问题，我们用传参来实现：在第一个servlet中setAttribute第二个servlet中getAttribute
转发共享同一个request和同一个response对象，在servlet中可以多次读取参数
5请求包含 传参 访问顺序（doGet还是doPost ）
1> 两个servlet的输出都有效
2> request.getRequestDispatcher("").include(request,response);
因为是请求包含，还是在项目内，getRequestDispatcher("")的参数可以不带项目名
这个include(request,response)可以理解成函数调用，相当于将第二个servlet的代码拷到这里来运行。
3>第一个servlet用doget第二个servlet用doget 第一个servlet用dopost第二个servlet用dopost
4>对于请求包含 第二个servlet在执行完以后还会回到第一个servlet的include(request,response)后面。
5>传参与转发的传参一样，采用setAttribute,getAttribute 。
dopost方式第二个servlet也能从页面拿到值。
不同的是，请求包含在第一个servlet关流，后面不会出异常，在中途调用out.flush() 流不会关闭

字节输出流和字符输出流的共存问题
结论：不能共存(跟get或post方式没关系)。即在同一个servlet中字符流与字节流不能共存，两种方法单独使用都是可以的
另外：如果要用字节流输出中文，用write(byte[])方法，因为它的out.print(“晚上好!”);//500错误。内部用iso8859-1读取，已经写死了，因此中文不行
转发时，两个servlet都输出信息的问题
转发用

Tomcat对于同response，只输出一次(把缓存中的内容刷出去)。刷了(close也一样)，流就关闭了,下面的转发就无法进行了，因为此时response已经提交了(整个转发链只会响应一次，即提交了) .
详细知识点见转发的第三点。
重定向 传参 访问顺序（doget还是dopost）
重定向用response.sendRedirect("/servletDemo4/servlet/Redir2Servlet"); 参数带项目名，因为发给浏览器要在tomcat目录下。
在重定向第一个servlet输出会被第二个servlet输出覆盖，其实是输出了，但是跳转的时间太快，人眼不可见。
无论第一个servlet是doget还是dopost，第二个servlet都是doget。因为转发过去直接在地址栏输入路径，不会在生成表单设置post
重定向，第二个servlet和第一个servlet的request和response都不是同一个对象了，因此无法通过request.setAttribute("age", 22); 和request.getAttribute("age");传参，并且，第二个servlet也无法通过request.getParameter("name");从页面获取参数。
重定向情况下，如要传参，则采用地址栏的url的？后面加key=value，多个用&连接。
采用地址栏传参的方式，在浏览器地址栏能看到参数值，因此要注意隐私问题—–加密
转发只能在站内进行（路径默认在项目内）而重定向可以在站外进行（如果是在站外，路径要带”http://”开头，站内要带项目名）如果非要在项目之间（站外）进行跳转，则必须采用重定向。
转发 传参 访问顺序（doget还是dopost）
第一个servlet用dopost第二个servlet也用dopost。第一个servlet用doget第二个servlet也用doget。
第二个servlet中的response会把缓存清空，即将上个servlet的内容清空，然后将此时的servlet的内容写入缓存，刷出去，显示到页面。
tomcat对于同一个servlet只输出一次（把缓存中的内容刷出去）如果第一个servlet刷了，流就关闭了。只会对response操作会出异常，因为此时的response已经提交，不能再转发了。
为解决上面的问题，我们用传参在第一个servlet中用request.setAttribute("age", 22);第二个servlet中用request.getAttribute("age"); 通过request容器来进行读写，因为转发其实是共享同一个request和同一个response对象。在转发过程中，servlet可以对request进行多次读取参数。
请求包含 传参 访问顺序（doget还是dopost）
请求包含用
<code class="hljs vbscript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"> RequestDispatcher rd = <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">request</span>.getRequestDispatcher(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"/servlet/Include2Servlet"</span>); rd.include(<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">request</span>, <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">response</span>);</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>
请求包含的机制可以理解成函数调用，相当于把第二个servlet 中的代码拷到这里来执行。
第一个servlet用doget第二个servlet用doget；第一个servlet用dopost第二个servlet也用dopost。
对于请求包含，第二个servlet在执行完之后还会回到第一个servlet的rd.include(request,
response);
之后。
请求包含与转发传参一样，也是共享同一个request和同一个response对象。不同的是，在请求包含中，如在第一个servlet关流，后面不会出异常，只是后面的不会执行了。如在第一个servlet刷即用out.flush();流不会关闭。请求包含我个人可以理解成是同一个servlet，只是包含的servlet是一个功能模块而已，所以在同一个servlet中，刷(flush)没有影响，实质还是在同一个servlet中。

知识点：
1字节输出流和字符输出流的共存问题
结论：在一个servlet中字符流与字节流不能共存，两种方法单独使用都是可以的
2转发时，两个servlet都输出信息的问题
正常的后面一个会覆盖前面，具体的可以看4.2和4.3
3重定向 传参 访问顺序（doGet还是doPost ）
1>方法是：response.sendRedirect() 因为转发给浏览器，要在tomcat目录下参数要带项目名
2>在重定向第一个servlet输出后会被第二个servlet输出覆盖，其实是输出了，但是跳转时间太快，人眼不可见
3>无论第一个servlet是dopost还是doget，第二个servlet都是doget，因为转发过去直接在地址栏输入路径。不会再生成表单设置post
4>重定向第二个servlet和第一个servlet的request和response不是同一个对象，无法用过serAttribute和getAttribute传参，第二个servlet无法通过getParamer从页面获取参数
5>如要传参，采用地址栏的url的？后面加key=value 形式进行传参，多个用&连接。采用地址栏传参方式
在浏览器地址栏可以看到所传的参数，因此要注意隐私问题----加密
6>转发只能在站内进行（路径默认在项目内）而重定向可以在站外进行（如果在站外，路径要带"http://"开头，站内要带项目名）
如果非要在项目之间（站外）进行跳转，不虚采用重定向
4转发 传参 访问顺序（doGet还是doPost ）
1>转发:第一个servlet用doget第二个就是用doget；第一个用dopost第二个也用dopost；
2>第二个servlet中的response会先把缓存清空，然后将此时的servlet的内容写到缓存，刷出去显示到页面
3>tomcat对同一个response只会输出一次，如果第一个servlet刷了即out.flush()
那么流在此就关闭了，后面转发，操作response都会出异常。因为此时的response已经提交，不能再转发了
4>为了解决上面问题，我们用传参来实现：在第一个servlet中setAttribute第二个servlet中getAttribute
转发共享同一个request和同一个response对象，在servlet中可以多次读取参数
5请求包含 传参 访问顺序（doGet还是doPost ）
1> 两个servlet的输出都有效
2> request.getRequestDispatcher("").include(request,response);
因为是请求包含，还是在项目内，getRequestDispatcher("")的参数可以不带项目名
这个include(request,response)可以理解成函数调用，相当于将第二个servlet的代码拷到这里来运行。
3>第一个servlet用doget第二个servlet用doget 第一个servlet用dopost第二个servlet用dopost
4>对于请求包含 第二个servlet在执行完以后还会回到第一个servlet的include(request,response)后面。
5>传参与转发的传参一样，采用setAttribute,getAttribute 。
dopost方式第二个servlet也能从页面拿到值。
不同的是，请求包含在第一个servlet关流，后面不会出异常，在中途调用out.flush() 流不会关闭
