SpringSecurity身份验证基础入门

对于没有访问权限的用户须要转到登陆表单页面。要实现访问控制的方法多种多样,能够经过Aop、拦截器实现,也能够经过框架实现(如:Apache Shiro、Spring Security)。

pom.xml添加依赖html

<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>

建立SpringSecurity配置类java

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 {
        //inMemoryAuthentication 从内存中获取
        auth
                .inMemoryAuthentication()
                .passwordEncoder(new BCryptPasswordEncoder())
                .withUser("admin")
                .password(new BCryptPasswordEncoder()
                        .encode("123456")).roles("USER");
    }
}

经过@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,经过authorizeRequests()定义哪些URL须要被保护、哪些不须要被保护。例如以上代码指定了/和/home不须要任何认证就能够访问,其余的路径都必须经过身份验证。
经过formLogin()定义当须要用户登陆时候,转到的登陆页面。
configureGlobal(AuthenticationManagerBuilder auth)方法,在内存中建立了一个用户,该用户的名称为admin,密码为123456,用户角色为USER。web

控制器:spring

@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";
    }

}

index.html安全

运行:ide

打开index.html,点击这里,若是没有登陆进入登陆页,已登陆跳转到hello.htmlspring-boot
