spring boot整合scurity做简单的登录校验

本篇文章给大家分享《spring boot整合scurity做简单的登录校验》，覆盖了数据库的常见基础知识，其实一个语言的全部知识点一篇文章是不可能说完的，但希望通过这些问题，让读者对自己的掌握程度有一定的认识(B 数)，从而弥补自己的不足，更好的掌握它。

开发环境：springboot
maven引入：

 <dependency><groupid>org.springframework.security.oauth</groupid><artifactid>spring-security-oauth2</artifactid><version>2.2.1.RELEASE</version></dependency><dependency><groupid>org.springframework.security</groupid><artifactid>spring-security-jwt</artifactid><version>1.0.10.RELEASE</version></dependency>

1、先在数据库创建用户表，用户名为username，密码名为password。下面是我用户表的实体

  private Integer id;
/**
* 昵称
*/
private String name;
/**
* 职位
*/
private String code;
/**
* 密码
*/
private String passwd;
/**
* 用户名
*/
private String username;
/**
* 手机号
*/
private String phone;
/**
* 创建时间
*/
private Date createdTime;

2、看项目是JPA、还是mybatis。我这边项目使用的是mybatis。需要有一个方法通过用户名获取用户信息。
3、创建一个用户验证类实现 UserDetails 继承用户实体

public class SecurityUser extends SysUser implements UserDetails {
private static  final  long serialVersiongUID = 1l;

public SecurityUser(SysUser sysUser) {
    if (null != sysUser) {
        this.setCode(sysUser.getCode());
        this.setCreatedTime(sysUser.getCreatedTime());
        this.setId(sysUser.getId());
        this.setName(sysUser.getName());
        this.setPasswd(sysUser.getPasswd());
        this.setPhone(sysUser.getPhone());
        this.setUsername(sysUser.getUsername());
    }
}


@Override
public Collection extends GrantedAuthority> getAuthorities() {
    Collection<grantedauthority> authorities = new ArrayList();
    String username = this.getUsername();
    if (username != null) {
        SimpleGrantedAuthority authority = new SimpleGrantedAuthority(username);
        authorities.add(authority);
    }
    return authorities;
}

@Override
public String getPassword() {
    return super.getPasswd();
}

//账户是否未过期,过期无法验证
@Override
public boolean isAccountNonExpired() {
    return true;
}

//指定用户是否解锁,锁定的用户无法进行身份验证
@Override
public boolean isAccountNonLocked() {
    return true;
}

//指示是否已过期的用户的凭据(密码),过期的凭据防止认证
@Override
public boolean isCredentialsNonExpired() {
    return true;
}

//是否可用 ,禁用的用户不能身份验证
@Override
public boolean isEnabled() {
    return true;
}
}</grantedauthority>

4、重点！创建一个scurity config配置类

 @Configuration
  @EnableWebSecurity
  public class UiSecurityConfig extends WebSecurityConfigurerAdapter {

 private static final Logger logger = LoggerFactory.getLogger(UiSecurityConfig.class);

 @Override
 protected void configure(HttpSecurity http) throws Exception { //配置策略
     http.csrf().disable();
     http.authorizeRequests().
             antMatchers("/static/**").permitAll().anyRequest().authenticated().
             and().formLogin().loginPage("/login").permitAll().successHandler(loginSuccessHandler()).
             and().logout().permitAll().invalidateHttpSession(true).
             deleteCookies("JSESSIONID").logoutSuccessHandler(logoutSuccessHandler()).
             and().sessionManagement().maximumSessions(10).expiredUrl("/login");
 }

 

 @Bean
 public BCryptPasswordEncoder passwordEncoder() { //密码加密
     return new BCryptPasswordEncoder(4);
 }

 @Bean
 public LogoutSuccessHandler logoutSuccessHandler() { //登出处理
     return new LogoutSuccessHandler() {
         @Override
         public void onLogoutSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
             try {
                 SecurityUser user = (SecurityUser) authentication.getPrincipal();
                 logger.info("USER : " + user.getUsername() + " LOGOUT SUCCESS !  ");
             } catch (Exception e) {
                 logger.info("LOGOUT EXCEPTION , e : " + e.getMessage());
             }
             httpServletResponse.sendRedirect("/login");
         }
     };
 }

 @Bean
 public SavedRequestAwareAuthenticationSuccessHandler loginSuccessHandler() { //登入处理
     return new SavedRequestAwareAuthenticationSuccessHandler() {
         @Override
         public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
             SysUser userDetails = (SysUser) authentication.getPrincipal();
  logger.info("USER : " + userDetails.getUsername() + " LOGIN SUCCESS !  ");

 //                登录成功后重定向路径
             response.sendRedirect("/");
         }
     };
 }
  //用户登录实现
 @Bean
 public UserDetailsService userDetailsService() {   
     return new UserDetailsService() {
         @Autowired
         private SysUserDao sysUserDao;//这里是引入数据库连接dao

         @Override
         public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
             SysUser userNmae = new SysUser();
             userNmae.setUsername(s);
            List<sysuser> listUser = sysUserDao.queryAll(userNmae);//通过用户名获取个用户信息
             SysUser user = null;
            if (listUser.size() > 0) {
                user = listUser.get(0);
            }
             if (user == null) throw new UsernameNotFoundException("Username " + s + " not found");
             return new SecurityUser(user);
         }
     };
 }
}</sysuser>

5、基础工作准备完成开始写controller

@Controller
public class LoginController {

  
@Resource
private SessionTool sessionTool;

//    获取登录页面
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login() {
    return "login";
}

@RequestMapping("/")
public String login(ModelMap map){
    SysUser sysUser = sessionTool.getUser();
    map.addAttribute("sysUser", sysUser);
    return "index";
}
}

6、从session获取用户信息

@Component
public class SessionTool {
public SysUser getUser() { //为了session从获取用户信息,可以配置如下
    SysUser user = new SysUser();
    SecurityContext ctx = SecurityContextHolder.getContext();
    Authentication auth = ctx.getAuthentication();
    if (auth.getPrincipal() instanceof UserDetails) user = (SysUser) auth.getPrincipal();
    return user;
}

public HttpServletRequest getRequest() {
    return ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
}
}

7、login.html页面（登录路径为login 请求方式为post，scurity自带的登录路径）

 <meta charset="UTF-8"><title>Title</title>

总结一下思路：
引入依赖包-》创建用户表-》创建用户表数据库查询接口-》创建用户校验类实现UserDetails接口-》创建scurity配置类继承 WebSecurityConfigurerAdapter 方法configure为配置校验策略-》创建controller配置登录页面跳转接口-》创建登陆页面用户名必须为username 密码为password 登录路径为'/login' 请求方式为post

由于scurity配置的密码检验是加密的为了测试可以在Test模块中获取加密后的密码然后存到用户表的password字段中。

    @Test
    public void encoder() {
        String password = "123123";
        BCryptPasswordEncoder encoder = new BCryptPasswordEncoder(4);
        String enPassword = encoder.encode(password);
        System.out.println(enPassword);
    }
