对于没有访问权限的用户需要转到登录表单页面。要实现访问控制的方法多种多样,可以通过Aop、拦截器实现,也可以通过框架实现(如:Apache Shiro、Spring Security)。

pom.xml添加依赖

<dependency>

创建SpringSecurity配置类

Spring Boot SpringSecurity5 身份验证-LMLPHP
import org.springframework.beans.factory.annotation.Autowired;

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 WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Override</br>
</span><span style="color: #0000ff;">protected</span> <span style="color: #0000ff;">void</span> configure(HttpSecurity http) <span style="color: #0000ff;">throws</span><span style="color: #000000;"> Exception {</br>

.authorizeRequests()</br>
.antMatchers(</span>"/", "/home"<span style="color: #000000;">).permitAll()</br>
.anyRequest().authenticated()</br>
.and()</br>
.formLogin()</br>
.loginPage(</span>"/login"<span style="color: #000000;">)</br>
.permitAll()</br>
.and()</br>
.logout()</br>
.permitAll();</br>
}</br> @Autowired</br>
</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span> configureGlobal(AuthenticationManagerBuilder auth) <span style="color: #0000ff;">throws</span><span style="color: #000000;"> Exception {</br>
auth</br>
.inMemoryAuthentication()</br>
.withUser(</span>"admin").password("123456").roles("USER"<span style="color: #000000;">);</br>
}</br>

}

Spring Boot SpringSecurity5 身份验证-LMLPHP

通过@EnableWebSecurity注解开启Spring Security的功能
继承WebSecurityConfigurerAdapter,并重写它的方法来设置一些web安全的细节
configure(HttpSecurity http)方法,通过authorizeRequests()定义哪些URL需要被保护、哪些不需要被保护。例如以上代码指定了/和/home不需要任何认证就可以访问,其他的路径都必须通过身份验证。
通过formLogin()定义当需要用户登录时候,转到的登录页面。
configureGlobal(AuthenticationManagerBuilder auth)方法,在内存中创建了一个用户,该用户的名称为admin,密码为123456,用户角色为USER。

控制器:

Spring Boot SpringSecurity5 身份验证-LMLPHP
@Controller
public class HelloController {
@RequestMapping(</span>"/"<span style="color: #000000;">)</br>
</span><span style="color: #0000ff;">public</span><span style="color: #000000;"> String index() {</br>
</span><span style="color: #0000ff;">return</span> "index"<span style="color: #000000;">;</br>
}</br> @RequestMapping(</span>"/hello"<span style="color: #000000;">)</br>
</span><span style="color: #0000ff;">public</span><span style="color: #000000;"> String hello() {</br>
</span><span style="color: #0000ff;">return</span> "hello"<span style="color: #000000;">;</br>
}</br></br> @RequestMapping(value </span>= "/login", method =<span style="color: #000000;"> RequestMethod.GET)</br>
</span><span style="color: #0000ff;">public</span><span style="color: #000000;"> String login() {</br>
</span><span style="color: #0000ff;">return</span> "login"<span style="color: #000000;">;</br>
}</br></br>
