1.springboot配置Tomcat两个端口,https和http的方式;
2.在https协议下,发送axios请求没反应,暂时用form表单解决;
3.运行jar包template might not exist报错及解决;

springboot配置Tomcat两个端口,https和http的方式
1.生成SSL证书
严格来说https不是一个独立协议,只是在http协议基础上增加了SSL/TLS加密层。所以我们需要先生成SSL证书,这里使用keytool生成jks。
keytool -genkey -alias client -keypass 12345678 -keyalg RSA -keysize 2048 -validity 365 -storetype PKCS12 -keystore ./client.p12 -storepass 12345678
2.配置client.p12和https端口
server:
ssl:
key-store: classpath:client.p12
key-store-password: 12345678
key-store-type: PKCS12
key-alias: client
# https的访问端口
port: 8443
3.配置http的8080端口WebServerFactoryCustomizer接口
WebServerFactory接口的几个重要实现:
-
TomcatServletWebServerFactory:对应于tomcat
-
JettyServletWebServerFactory:对应jetty
-
UndertowServletWebServerFactory:对应undertow
-
NettyReactiveWebServerFactory:对应netty
Spring Boot默认使用http/1.1协议。所以我们增加额外的自定义https连接器。
package com.shanxi.gis.config;
import org.apache.catalina.connector.Connector;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.server.WebServerFactory;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.stereotype.Component;
@Component
public class TomcatServerCustomer implements WebServerFactoryCustomizer<TomcatServletWebServerFactory> {
@Override
public void customize(TomcatServletWebServerFactory factory) {
final Connector httpConn = new Connector("HTTP/1.1");
httpConn.setPort(8080);
factory.addAdditionalTomcatConnectors(httpConn);
}
}
4.启动项目
运行项目后可以看到启动了https的8843和http的8080两个端口
项目应用:在某项目中有一个功能需要https协议
Tomcat启动https和http两个端口
TomcatServerCustomer.java文件
package com.shanxi.gis.config;
import org.apache.catalina.connector.Connector;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.server.WebServerFactory;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.stereotype.Component;
@Component
public class TomcatServerCustomer implements WebServerFactoryCustomizer<TomcatServletWebServerFactory> {
@Value("${ServerHttpPort}")
Integer httpHost;
@Override
public void customize(TomcatServletWebServerFactory factory) {
final Connector httpConn = new Connector("HTTP/1.1");
httpConn.setPort(httpHost);
factory.addAdditionalTomcatConnectors(httpConn);
}
}
application.yml配置文件

ssl:
key-store: classpath:client.p12
key-store-password: 12345678
key-store-type: PKCS12
key-alias: client
# https的访问端口

# 部署服务器的配置
ServerHttpsUrl: https://localhost:8443 # https的url
ServerHttpUrl: http://localhost:8080 # http的url
ServerHttpPort: 8080 # http的端口号
LoginPassword: Admin@1a2 # 登陆的密码

根据http或者https确定拦截后到哪个页面
LoginAuthorInterceptor.java文件
request.getScheme(); // for example, http, https, or ftp.
package com.shanxi.gis.interceptor;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
/**
* spring的拦截器,
* 1.在容器中,@Component
* 2.是spring的拦截器 implements HandlerInterceptor
*/
@Component
public class LoginAuthorInterceptor implements HandlerInterceptor {
@Value("${ServerHttpsUrl}")
String httpsUrl;
@Value("${ServerHttpUrl}")
String httpUrl;
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
// 如果没有登陆,就去登陆页面,如果登陆了就放行
HttpSession session = request.getSession();
Object user = session.getAttribute("user");
System.out.println(user);
if ("admin".equals(user)){
return true;
}else {
// 没有登陆,就去登陆页面
String scheme = request.getScheme(); // for example, http, https, or ftp.
// 如果是http就去,http的端口
if ("http".equals(scheme)){
response.sendRedirect(httpUrl+"/user/loginPage");
}
// 否则就去https的端口
response.sendRedirect(httpsUrl+"/user/loginPage");
return false;
}
}
}
后端共享值,前端form表单获取
login.html页面
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">

<body>
<div class="login-container" id="app">
<h2>欢迎登录</h2>
<!-- "https://localhost:8443/user/login"-->
<form :action=url method="post">
<label for="username">用户名:</label>
<input type="text" id="username" v-model="username" placeholder="请输入用户名" required name="username">

let app = new Vue({
el:"#app",
data:{
username:"",
password:"",
url:"[[${httpsUrl}]]",
},
methods:{
},
created(){},
})
</script>
</body>
</html>
后端共享值+跳转loginController.java
@Value("${ServerHttpsUrl}")
String httpsUrl;
// 1.先到登陆页面
@RequestMapping("/loginPage") // /user/loginPage
public ModelAndView loginPage(){
ModelAndView mv = new ModelAndView("user/login");
mv.addObject("httpsUrl", httpsUrl + "/user/login");
return mv;
}
配置文件设置url
server:

key-store: classpath:client.p12
key-store-password: 12345678
key-store-type: PKCS12
key-alias: client

问题:在https协议下,发送axios请求没反应
问题如下:
解决方案一:用form表单
后端,用户名和密码正确后,重定向到index.html页面
// form表单下重定向到indexPage页面
response.sendRedirect(httpsUrl+“/user/indexPage”);
package com.shanxi.gis.controller;
import com.shanxi.gis.entity.ResData;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;
import java.util.Objects;
@Controller
@RequestMapping("/user")
@CrossOrigin // 允许跨域
public class LoginController {
@Value("${ServerHttpsUrl}")
String httpsUrl;
@Value("${LoginPassword}")
String loginPassword;
// 1.先到登陆页面
@RequestMapping("/loginPage") // /user/loginPage
public ModelAndView loginPage(){
ModelAndView mv = new ModelAndView("user/login");
mv.addObject("httpsUrl", httpsUrl + "/user/login");
return mv;
}
// 2.处理前端的axios请求
@Autowired
HttpSession session; // TODO:保存用户名到session
@RequestMapping("/login")
@ResponseBody
public ResData login(
String username,
String password, HttpServletResponse response
) throws IOException {
System.out.println(username +"//"+ password);
if (Objects.equals(username, "") || username==null ||
Objects.equals(password, "") || password==null
){
return new ResData(1001, "必填项为空", null);
}
if (!"admin".equals(username) || !loginPassword.equals(password)){
return new ResData(1002, "用户名|密码错误", null);
}
session.setAttribute("user",username); // TODO:set进session
// form表单下重定向到indexPage页面
response.sendRedirect(httpsUrl+"/user/indexPage");
return new ResData(200, "ok", null);
}
// 3.登陆成功到index页面
@RequestMapping("/indexPage")
public String loginIndex(){
return "gis/index";
}
}
前端发送form表单
<form :action=url method=“post”>
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>登陆页面</title>
<link rel="stylesheet" href="/bootstrap/css/bootstrap.min.css">
<script src="/js/jquery-3.5.1.js"></script>
<script src="/bootstrap/js/bootstrap.js"></script>
<script src="/js/axios.min.js"></script>
<script src="/js/vue.min-v2.5.16.js"></script>
<link rel="stylesheet" href="/css/login.css">
</head>
<body>
<div class="login-container" id="app">
<h2>欢迎登录</h2>
<!-- "https://localhost:8443/user/login"-->
<form :action=url method="post">
<label for="username">用户名:</label>
<input type="text" id="username" v-model="username" placeholder="请输入用户名" required name="username">
<label for="password">密码:</label>
<input type="password" id="password" v-model="password" placeholder="请输入密码" required name="password">
<input type="submit" value="登录" @click="loginBtn" class="btn btn-primary btn-block">
</form>
</div>
<script>
let app = new Vue({
el:"#app",
data:{
username:"",
password:"",
url:"[[${httpsUrl}]]",
},
methods:{
loginBtn(){
console.log("send----")
let params = new URLSearchParams();
params.append("username",this.username)
params.append("password",this.password)
// axios.post("/user/login",params)
axios.post("/user/login",params)
.then(response=>{
console.log("axios")
if (response.data.code==200){
// alert("登陆成功")
location.href= "/user/indexPage"
}else {
alert(response.data.msg)
}
})
}
},
created(){},
})
</script>
</body>
</html>
项目的打包部署
1.template might not exist or might not be accessible by any of the configured Template Resolvers
错误描述:
在idea中进行测试,所有功能都可以实现,尝试打包成jar包后运行,进入首页后没有显示用户信息页面,报500异常,后台显示Error resolving template [/user/info], template might not exist or might not be accessible by any of the configured Template Resolvers
报错信息:
2023-07-08 10:16:11.298 ERROR 28396 — [p-nio-80-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.thymeleaf.exceptions.TemplateInputException: Error resolving template [/user/info], template might not exist or might not be accessible by any of the configured Template Resolvers] with root cause
org.thymeleaf.exceptions.TemplateInputException: Error resolving template [/user/info], template might not exist or might not be accessible by any of the configured Template Resolvers
解决方案一:
@RequestMapping("/infoPage")
public String infoPage(){
return "/user/info";
}
跳转页面去掉第一个反斜杠,改为如下
@RequestMapping("/infoPage")
public String infoPage(){
return "user/info";
}
thymeleaf + Spring Boot 在开发环境正常,但用jar运行时报错 Error resolving template template might not exist or might not be accessible;
就可以了
解决方案二:
spring.thymeleaf.cache=false
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
改成
spring.thymeleaf.cache=false
spring.thymeleaf.prefix=classpath:/templates
spring.thymeleaf.suffix=.html
## spring相关的配置
spring:
# 连接数据库
datasource:
type: com.alibaba.druid.pool.DruidDataSource
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3306/javaweb?useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true
username: root
password: 123
## 设置上传文件大小
servlet:
multipart:
max-file-size: 10MB # 设置单个文件最大大小为10MB
# 另一种解决方案
thymeleaf:
cache: false
prefix: classpath:/templates
suffix: .html
此时所有跳页面的都要加反斜杠文章来源:https://www.toymoban.com/news/detail-768299.html
