Application
Start by creating a simple Spring Boot java project with no authentication. Select Spring Web and Thymeleaf as dependencies.
// src/main/java/com/example/securingweb/App.java
package com.example.securingweb;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
// src/main/java/com/example/securingweb/MvcConfig.java
package com.example.securingweb;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class MvcConfig implements WebMvcConfigurer {
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("hello");
}
}
/*
// src/main/resources/templates/hello.html
<h1>Hello World</h1>
*/
http://localhost:8080/
