关于如何设置IDEA中的servlet的模板

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

2. 进行如图中的设置

   

由于我已经设置了java文件的作者信息相关格式，所以不需要在这里面再加入文件头信息

模板代码如下：

#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 {
        // 处理post请求乱码问题
        request.setCharacterEncoding("utf-8");
        // 处理响应乱码问题:字节流需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. 测试的效果如下：新建servlet时，选择 Create New Servlet

   

   这样生成的一个servlet的代码模板如下：

   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 1769862620@qq.com
    * @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 {
           // 处理post请求乱码问题
           request.setCharacterEncoding("utf-8");
           // 处理响应乱码问题:字节流需getBytes("UTF-8")
           response.setContentType("text/html;charset=utf-8");
       }
   
       @Override
       protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
           doPost(request, response);
       }
   }
