右键new的时候没有Web filter等文件? 是因为2023版的IDEA已经不默认支持Web filter模板了。所以别再看配置有没有问题了，人家23IDEA压根就没有默认的该模板。如果要使用的话，需要自己创建模板使用。本文只提供Web filter or Servlet的模版,需其余的模版可根据本文创建模版的方法,自行搜索其他模版进行创建。先看配置IDEA下一步打开“文件 -> 设置 -> 编辑器 -> 文件和代码模板”

过滤器Web filter复制粘贴模板

<code>#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end

#parse("File Header.java")

import javax.servlet.annotation.WebFilter;

import javax.servlet.Filter;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import javax.servlet.FilterChain;

import java.io.IOException;

@WebFilter("/${Class_Name}")

public class ${Class_Name} implements Filter {

public void init(FilterConfig config) throws ServletException {

}

public void destroy() {

}

@Override

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws ServletException, IOException {

//放行

chain.doFilter(request, response);

}

}

同理添加Servlet模板

#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end

#parse("File Header.java")

import java.io.*;

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;

@WebServlet("/${Class_Name}")

public class ${Class_Name} extends HttpServlet {

private String message;

public void init() {

}

@Override

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {

}

@Override

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException {

this.doGet(request, response);

}

}

最后右击新建，就有自己创建的模板啦
