? Writer

Code Combat:

1. Introducing the dependencies required to use the Serlvet native API in Pom.xml

1 <!--development JSP needs to rely on, there are HttpServletRequest,2 HttpServletResponse and other native parameters begin -3     <Dependency>4       <groupId>Org.apache.tomcat</groupId>5       <Artifactid>Jsp-api</Artifactid>6       <version>6.0.53</version>7     </Dependency>8     9     <Dependency>Ten       <groupId>Org.apache.tomcat</groupId> One       <Artifactid>Servlet-api</Artifactid> A       <version>6.0.48</version> -     </Dependency> -     <!--development JSP needs to rely on, there are HttpServletRequest, the HttpServletResponse and other native parameter end -

2. Writing index.jsp

1 <BR/><BR/>2 <P><b>Using the Serlvet native API as a parameter to the target method begin</b></P>3 <ahref= "Servletapitest/testservletapi">Testservletapi</a>4 <P><b>Using the Serlvet native API as a parameter to the target method</b></P>

3. Writing handle

1  Packagecom.study.springmvc.handlers;2 3 Importjava.io.IOException;4 ImportJava.io.Writer;5 6 Importjavax.servlet.http.HttpServletRequest;7 ImportJavax.servlet.http.HttpServletResponse;8 9 ImportOrg.springframework.stereotype.Controller;Ten Importorg.springframework.web.bind.annotation.RequestMapping; One  A@RequestMapping ("/servletapitest") - @Controller -  Public classServletapitest { the  -      Public Static FinalString success= "SUCCESS"; -      -     /** + * The following types can be specifically supported using the Serlvet native API as a parameter of the target method -      *  + * HttpServletRequest A * HttpServletResponse at * HttpSession - * Java.security.Principal - * Locale InputStream - * OutputStream - * Reader - * Writer in      * @throwsIOException -      */ to@RequestMapping ("/testservletapi") +      Public voidTestservletapi (httpservletrequest request, -HttpServletResponse response, Writer out)throwsIOException { theSystem.out.println ("Testservletapi," + Request + "," +response); *Out.write ("Hello Springmvc"); $ //return SUCCESS;Panax Notoginseng     } -}

4. Enter the address http://127.0.0.1:8080/SpringMVC/access to index.jsp click on the second part of the index.jsp written in the hyperlinks to see the effect
