Project Setup: - Create a Spring Boot Project: Use Spring Initializr
(https://start.spring.io/) to create a new Spring Boot project with the
following dependencies: - Spring Web - Spring Security - Spring Data JPA -
H2 Database - Lombok (optional, for code simplification) - Create a VueJS
Project: Use Vue CLI (https://cli.vuejs.org/) to create a new VueJS project:

bash vue create vue-frontend

- Install Required Dependencies: Add
any additional dependencies for your specific requirements in both the Spring
Boot and VueJS projects. 2. Spring Boot Backend Setup: - Database
Configuration: Configure the embedded H2 database in your
application.properties file:

spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driverClassName=org.h2.Driver spring.jpa.database-
platform=org.hibernate.dialect.H2Dialect ```
{% endraw %}
 \- **Create User Entity:** Define
a User entity with properties like username, password, and roles:
{% raw %}
 ```java
@Entity @Data public class User { @Id @GeneratedValue(strategy =
GenerationType.IDENTITY) private Long id; private String username; private
String password; @ManyToMany(fetch = FetchType.EAGER) @JoinTable(name =
"user_role", joinColumns = @JoinColumn(name = "user_id"), inverseJoinColumns =
@JoinColumn(name = "role_id")) private Set roles = new HashSet<>(); } ```
{% endraw %}
 \-
**Create Role Entity:** Define a Role entity:
{% raw %}
 ```java @Entity @Data public
class Role { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private
Long id; private String name; } ```
{% endraw %}
 \- **Configure Spring Security:** In your
{% raw %}`SecurityConfig`{% endraw %} class, configure the authentication and authorization rules:
{% raw %}

```java @Configuration @EnableWebSecurity public class SecurityConfig extends
WebSecurityConfigurerAdapter { @Autowired private UserDetailsService
userDetailsService; @Override protected void
configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
} @Override protected void configure(HttpSecurity http) throws Exception {
http .authorizeRequests() .antMatchers("/api/**").authenticated()
.anyRequest().permitAll() .and() .formLogin() .loginPage("/login")
.permitAll() .and() .logout() .permitAll(); } @Bean public PasswordEncoder
passwordEncoder() { return new BCryptPasswordEncoder(); } } ```
{% endraw %}
 \- **Create a
User Controller:** Create a controller to handle user registration and login
requests:
{% raw %}
 ```java @RestController @RequestMapping("/api") public class
UserController { @Autowired private UserService userService;
@PostMapping("/register") public ResponseEntity registerUser(@RequestBody User
user) { User savedUser = userService.saveUser(user); return
ResponseEntity.ok(savedUser); } @PostMapping("/login") public ResponseEntity
login(@RequestBody LoginRequest request) { // Implement login logic } } ```
{% endraw %}

**3. VueJS Frontend Setup:** \- **Create Login/Registration Components:**
Create Vue components for handling user login and registration:
{% raw %}
 ```vue

Username:

Password:

Login

- Implement API Calls: Use Axios or Fetch API to make requests to the
Spring Boot backend API endpoints for registration, login, and other
operations. - Handle Authentication: Use Vuex or other state management
libraries to manage user authentication state and access restricted content
based on user roles. 4. Integration and Deployment: - Connect VueJS to
Spring Boot: Configure your VueJS application to access the backend REST
APIs. - Deploy the Application: Deploy your Spring Boot application (as a
WAR or JAR file) to a web server like Tomcat or Jetty. Deploy your VueJS
application to a static hosting service or serve it from the Spring Boot
application. 5. Tips and Best Practices: - Use Secure Passwords: Use
strong passwords and password hashing techniques (like bcrypt) for security.
- Limit User Access: Implement authorization rules to restrict access to
specific resources based on user roles. - Validate Input: Sanitize and
validate user input to prevent injection attacks. - Regularly Update
Dependencies: Keep your frameworks and libraries up-to-date to benefit from
security patches and bug fixes. 6. Code Snippets:
