How can I implement OAuth in a Java application?

To implement OAuth in a Java application, you can use libraries like Spring Security OAuth or Apache Oltu. Would you like a code example?

Yes, please provide a code example using Spring Security.

Sure! Here's a basic example:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
            .antMatchers("/public/**").permitAll()
            .anyRequest().authenticated()
            .and()
            .oauth2Login();
    }
}

This configures OAuth2 login for your application.

What are the main benefits of using OAuth for security?

The main benefits of using OAuth include improved security by not sharing passwords, delegated access, and better user experience.
