springboot security基本配置

1、添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

2、配置文件

默认用户名user ,密码每次启动随机生成，可以在日志中查看

也可以在配置文件中自定义

spring.security.user.name=sang
spring.security.password=123
spring.security.user.roles=admin

3、基于内存认证

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class testSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("root").password("123").roles("admin", "user")
                .and()
                .withUser("sang").password("123").roles("user");

    }

}

4、授权

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class testSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/admin/**").hasRole("admin")
                .antMatchers("/user/**").access("hasAnyRole('admin','user')")
                .anyRequest()
                .authenticated()
                .and()
                .formLogin()
                .loginProcessingUrl("/login")
                .permitAll()
                .and()
                .csrf()
                .disable();
    }

}

• .formLogin() 开启表单登录
• .csrf() .disable() 关闭csrf
• .logout 开启注销登录配置
• .logoutUrl(“/logout”) 注销登录请求url 为"/logout" , 默认也是"/logout"
• .logoutSuccessUrl(“/”) 注销成功后去"/" 页面
• .clearAuthentication(true) 是否清除身份认证信息，默认true
• .invaliddateHttpSession(true) 是否使session失效，默认true

5、方法安全

@EnableGlobalMethodSecurity开启基于注解的安全配置

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class testSecurityConfig extends WebSecurityConfigurerAdapter {

}

@PreAuthorize 在方法执行前验证

@PostAuthorize 在方法执行后验证

写法

@PreAuthorize("@permission.admin()") 调用方法前先去调用admin方法
@PreAuthorize("hasRole('admin' and hasRole('user'))") 调用前需要有admin和user角色
@PreAuthorize("hasAnyRole('admin', 'user')") 调用前需要有admin和user角色

项目实战

@PreAuthorize("@permission.admin()")
@ApiOperation("获取文章详情")
@GetMapping("/{articleId}")
public ResponseResult getArticle(@ApiParam(value = "文章ID", required = true) @PathVariable("articleId") String articleId) {
    return articleService.getArticleById(articleId);
}

@Slf4j
@Service("permission")
public class PermissionService {

    @Autowired
    private IUserService userService;

    public boolean admin() {
        //拿到request和response
        ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = requestAttributes.getRequest();
        String tokenKey = CookieUtils.getCookie(request, Constants.User.COOKIE_TOKEN_KEY);

        //没有令牌的key,没有登录，不用往下执行
        if (StrUtil.isEmpty(tokenKey)) {
            log.info("您没有登录");
            return false;
        }
        User user = userService.checkUser();
        if (user == null) {
            log.info("您不是管理员");
            return false;
        }
        if (Constants.User.ROLE_ADMIN.equals(user.getRoles())) {
            //管理员
            return true;
        }
        return false;

    }
