IDEA好用的Servlet模板

不会再IDEA中创建模板点击这里看教程

---

这是模板内容,直接创建自己的模板复制用即可

#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end
#parse("File Header.java")
#set( $packageName1 = "#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != '')${PACKAGE_NAME}.#end#parse('File Header.java')" )
#set( $packageName2 = "#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != '')${PACKAGE_NAME}/#end#parse('File Header.java')" )

import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.annotation.*;
import java.io.IOException;
import java.io.PrintWriter;
/**
 * @auther LiuWeirui
 * @date ${DATE} ${TIME}
 */
 //更改@WebServlet中value的值,可以修改访问该Servlet文件的名称,规范value = "/visit name"
@WebServlet(name = "${NAME}", value = "/${NAME}")
public class ${NAME} extends HttpServlet {

    /**
     * Constructor of the object.
     */
    public ${NAME}() {
        super();
    }

    /**
     * Destruction of the servlet. 

     */
    public void destroy() {
        super.destroy(); // Just puts "destroy" string in log
        // Put your code here
    }

    /**
     * The doGet method of the servlet. 

     * 

     * This method is called when a form has its tag value method equals to get.
     *
     * @param request  the request send by the client to the server
     * @param response the response send by the server to the client
     * @throws ServletException if an error occurred
     * @throws IOException      if an error occurred
     */
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doPost(request, response);
    }

    /**
     * The doPost method of the servlet. 

     * 

     * This method is called when a form has its tag value method equals to post.
     *
     * @param request  the request send by the client to the server
     * @param response the response send by the server to the client
     * @throws ServletException if an error occurred
     * @throws IOException      if an error occurred
     */
    public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        //设置请求和响应数据的编码
        request.setCharacterEncoding("UTF-8");
        response.setCharacterEncoding("UTF-8");
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        //页面内容
        out.println("");
        out.println("");
        out.println("  ");
        out.println("  ");
        out.print("    This is ");
        out.print(this.getClass());
        out.println(", using the POST method");
        out.println("  ");
        out.println("");
        out.flush();
        out.close();
    }

    /**
     * Initialization of the servlet. 

     *
     * @throws ServletException if an error occurs
     */
    public void init() throws ServletException {
        // Put your code here
    }
    
    /**
    * web.xml配置文件书写
    * 
    *   ${NAME}
    *   $packageName1${NAME}
    * 
    
    * 
    *   ${NAME}
    *   /$packageName2${NAME}
    * 
    */
}

 

优点:

1.设置好的请求和响应数据的编码

2.处理好的doGet()和doPost()方法

3.记录日期和创建者(创建者自己改,这里我用的本人的)

4.导入好的包和设置好的包名

5.设置好的@WebServlet属性,设置@WebServlet属性可以替代配置web.xml

6.设置好的配置web.xml文件的内容,复制好即可用

 

问题:

1.web配置文件的内容有些问题,如图:

这是正常情况,在包下创建文件

这是缺省状态下创建的文件

 

的内容在缺省状态下会出现PACKAGE_NAME.,这是以下这段代码导致的问题

#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != '')${PACKAGE_NAME}.#end#parse('File Header.java')

这段代码貌似不能出现在注释内容里,不然就会出问题,在包中创建正常显示,但在缺省状态下就会显示PACKAGE_NAME

使用前还需自己修改
