Spring Boot:整合Spring Security

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
 
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
 
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/", "/home").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
            .logout()
                .permitAll();
    }
 
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .inMemoryAuthentication()
                .withUser("user").password("{noop}password").roles("USER")
                .and()
                .withUser("admin").password("{noop}password").roles("USER", "ADMIN");
    }
}

这段代码定义了一个简单的Spring Security配置，它允许对安全配置进行定制。它使用内存中的用户存储，但在实际应用中，你可能需要连接到数据库或其他用户存储。这个配置还展示了如何允许公开的路径（如主页和登录页），以及如何保护所有其他路径，需要认证后才能访问。
