這篇文章主要講解了spring boot整合scurity如何實現簡單的登錄校驗，內容清晰明了，對此有興趣的小伙伴可以學習一下，相信大家閱讀完之后會有幫助。
開發環境：springboot
maven引入：
<dependency>
<groupId>org.springframework.security.oauth</groupId>
<artifactId>spring-security-oauth3</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、先在數據庫創建用戶表，用戶名為username，密碼名為password。下面是我用戶表的實體
private Integer id; /** * 昵稱 */ private String name; /** * 職位 */ private String code; /** * 密碼 */ private String passwd; /** * 用戶名 */ private String username; /** * 手機號 */ private String phone; /** * 創建時間 */ private Date createdTime;
2、看項目是JPA、還是mybatis。我這邊項目使用的是mybatis。需要有一個方法通過用戶名獲取用戶信息。
3、創建一個用戶驗證類實現 UserDetails 繼承用戶實體
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();
}
//賬戶是否未過期,過期無法驗證
@Override
public boolean isAccountNonExpired() {
return true;
}
//指定用戶是否解鎖,鎖定的用戶無法進行身份驗證
@Override
public boolean isAccountNonLocked() {
return true;
}
//指示是否已過期的用戶的憑據(密碼),過期的憑據防止認證
@Override
public boolean isCredentialsNonExpired() {
return true;
}
//是否可用 ,禁用的用戶不能身份驗證
@Override
public boolean isEnabled() {
return true;
}
}4、重點！創建一個scurity config配置類
@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() { //密碼加密
return new BCryptPasswordEncoder(4);
}
@Bean
public LogoutSuccessHandler logoutSuccessHandler() { //登出處理
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() { //登入處理
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 ! ");
// 登錄成功后重定向路徑
response.sendRedirect("/");
}
};
}
//用戶登錄實現
@Bean
public UserDetailsService userDetailsService() {
return new UserDetailsService() {
@Autowired
private SysUserDao sysUserDao;//這里是引入數據庫連接dao
@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
SysUser userNmae = new SysUser();
userNmae.setUsername(s);
List<SysUser> listUser = sysUserDao.queryAll(userNmae);//通過用戶名獲取個用戶信息
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);
}
};
}
}5、基礎工作準備完成開始寫controller
@Controller
public class LoginController {
@Resource
private SessionTool sessionTool;
// 獲取登錄頁面
@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、從session獲取用戶信息
@Component
public class SessionTool {
public SysUser getUser() { //為了session從獲取用戶信息,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頁面（登錄路徑為login 請求方式為post，scurity自帶的登錄路徑）
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form action="/login" method="post"> 用戶名 : <input type="text" name="username"/> 密碼 : <input type="password" name="password"/> <input type="submit" value="登錄"> </form> </body> </html>
總結一下思路：
引入依賴包-》創建用戶表-》創建用戶表數據庫查詢接口-》創建用戶校驗類實現UserDetails接口-》創建scurity配置類繼承 WebSecurityConfigurerAdapter 方法configure為配置校驗策略-》創建controller配置登錄頁面跳轉接口-》創建登陸頁面用戶名必須為username 密碼為password 登錄路徑為'/login' 請求方式為post
由于scurity配置的密碼檢驗是加密的為了測試可以在Test模塊中獲取加密后的密碼然后存到用戶表的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);
