How to use Java framework to integrate front-end framework?
Steps to integrate mainstream front-end frameworks with Java back-end: Angular integration: Use Spring Boot to create a back-end, import Angular scripts, create HTML pages, and define controllers. React integration: Same as above, but using React scripts and components. Vue.js integration: Same as above, but using Vue.js scripts and components.
How to use the Java framework to integrate the front-end framework
In modern Web development, integrating the front-end framework with the Java back-end framework has been becoming more and more common. This article explains how to use Spring Boot to integrate with popular front-end frameworks such as Angular, React, and Vue.js.
Angular integration
@SpringBootApplication public class SpringBootAngularDemoApplication { public static void main(String[] args) { SpringApplication.run(SpringBootAngularDemoApplication.class, args); } }
<!-- angular.html --> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular.min.js"></script> </head> <body ng-app="myApp"> <div> <input ng-model="name"> <button ng-click="greet()">Greet</button> </div> <h3 ng-bind="greeting"></h3> </body> </html>
// main.js angular.module('myApp', []) .controller('myCtrl', function($scope) { $scope.greeting = ""; $scope.greet = function() { $scope.greeting = "Hello, " + $scope.name + "!"; }; });
React integration
@SpringBootApplication public class SpringBootReactDemoApplication { public static void main(String[] args) { SpringApplication.run(SpringBootReactDemoApplication.class, args); } }
<!-- index.html --> <html> <head> <script src="https://unpkg.com/react@17/umd/react.production.min.js"></script> <script src="https://unpkg.com/react-dom@17/umd/react-dom.production.min.js"></script> <script src="main.js"></script> </head> <body> <div id="root"></div> </body> </html>
// main.js const Greeting = () => <h1 id="Hello-World">Hello, World!</h1>; ReactDOM.render(<Greeting />, document.getElementById("root"));
Vue.js integration
@SpringBootApplication public class SpringBootVueDemoApplication { public static void main(String[] args) { SpringApplication.run(SpringBootVueDemoApplication.class, args); } }
<!-- index.html --> <html> <head> <script src="https://unpkg.com/vue@2.6.12/dist/vue.js"></script> <script src="main.js"></script> </head> <body> <div id="app"></div> </body> </html>
// main.js new Vue({ el: "#app", data: { message: "Hello, Vue!" }, template: "<div>{{ message }}</div>" });
Practical Case
Suppose you are building a simple web application that allows users to create a profile that includes name and age. Here's how to integrate the frontend using Spring Boot and Angular:
Java Backend
@Entity public class Profile { private Long id; private String name; private Integer age; // getters and setters } @SpringBootApplication public class SpringBootAngularDemoApplication { public static void main(String[] args) { SpringApplication.run(SpringBootAngularDemoApplication.class, args); } }
Angular Frontend
<!-- profile.html --> <div> <form> <label>Name:</label> <input type="text" [(ngModel)]="profile.name"> <br> <label>Age:</label> <input type="number" [(ngModel)]="profile.age"> <br> <button type="submit">Save</button> </form> </div>
// profiles.controller.js angular.module('myApp') .controller('ProfilesCtrl', function($scope, $http) { $scope.save = function() { $http.post('/profiles', $scope.profile) // handle server response }; });
By following With this guide, you can easily integrate front-end frameworks with Java backends and create powerful web applications.

Java code will have performance differences when running on different platforms. 1) The implementation and optimization strategies of JVM are different, such as OracleJDK and OpenJDK. 2) The characteristics of the operating system, such as memory management and thread scheduling, will also affect performance. 3) Performance can be improved by selecting the appropriate JVM, adjusting JVM parameters and code optimization.

Reasons for writing platform-specific code in Java include access to specific operating system features, interacting with specific hardware, and optimizing performance. 1) Use JNA or JNI to access the Windows registry; 2) Interact with Linux-specific hardware drivers through JNI; 3) Use Metal to optimize gaming performance on macOS through JNI. Nevertheless, writing platform-specific code can affect the portability of the code, increase complexity, and potentially pose performance overhead and security risks.

Java will further enhance platform independence through cloud-native applications, multi-platform deployment and cross-language interoperability. 1) Cloud native applications will use GraalVM and Quarkus to increase startup speed. 2) Java will be extended to embedded devices, mobile devices and quantum computers. 3) Through GraalVM, Java will seamlessly integrate with languages such as Python and JavaScript to enhance cross-language interoperability.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
