關於如何設置IDEA中的servlet的模板

1. 點擊左上角的File: Setting --> Editor --> File and Code Templates --> Other --> web -->Servlet Annotated Class.java

2. 進行如圖中的設置

   

由於我已經設置了java文件的作者信息相關格式，所以不需要在這里面再加入文件頭信息

模板代碼如下：

#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end
#parse("File Header.java")
@javax.servlet.annotation.WebServlet(name = "${Entity_Name}", urlPatterns="/${Entity_Name}")
public class ${Class_Name} extends javax.servlet.http.HttpServlet {
    @Override
    protected void doPost(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws javax.servlet.ServletException, java.io.IOException {
        // 處理post請求亂碼問題
        request.setCharacterEncoding("utf-8");
        // 處理響應亂碼問題:字節流需getBytes("UTF-8")
        response.setContentType("text/html;charset=utf-8"); 
    }
    
    @Override
    protected void doGet(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws javax.servlet.ServletException, java.io.IOException {
        doPost(request,response);
    }
}

3. 測試的效果如下：新建servlet時，選擇 Create New Servlet

   

   這樣生成的一個servlet的代碼模板如下：

   package com.luwanglin.servlet;
   
   import javax.servlet.ServletException;
   import javax.servlet.annotation.WebServlet;
   import javax.servlet.http.HttpServlet;
   import javax.servlet.http.HttpServletRequest;
   import javax.servlet.http.HttpServletResponse;
   import java.io.IOException;
   
   /** * @author luwanglin * @email [e-mail] * @Date 2020/9/1 21:51 * @Version 1.0 */
   @WebServlet(name = "HelloServlet", urlPatterns = "/HelloServlet")
   public class HelloServlet extends HttpServlet {
       @Override
       protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
           // 處理post請求亂碼問題
           request.setCharacterEncoding("utf-8");
           // 處理響應亂碼問題:字節流需getBytes("UTF-8")
           response.setContentType("text/html;charset=utf-8");
       }
   
       @Override
       protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
           doPost(request, response);
       }
   }
