Spring Boot SpringSecurity5 身份验证

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

复制代码
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-thymeleaf</artifactId>

</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-security</artifactId>

</dependency>

复制代码

创建SpringSecurity配置类

复制代码
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

protected void configure(HttpSecurity http) throws Exception {

http

.authorizeRequests()

.antMatchers(
"/", "/home").permitAll()

.anyRequest().authenticated()

.and()

.formLogin()

.loginPage(
"/login")

.permitAll()

.and()

.logout()

.permitAll();

}

@Autowired

public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

auth

.inMemoryAuthentication()

.withUser(
"admin").password("123456").roles("USER");

}

}

复制代码

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:

复制代码
@Controller
public class HelloController {

@RequestMapping("/")

public String index() {

return "index";

}

@RequestMapping("/hello")

public String hello() {

return "hello";

}

@RequestMapping(value = "/login", method = RequestMethod.GET)

public String login() {

return "login";

}

}

复制代码

index.html

复制代码
<!DOCTYPE html>

复制代码

运行:

打开index.html,点击这里,如果没有登录进入登录页,已登录跳转到hello.html
