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()); }}@Overridepublic 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;}@Overridepublic String getPassword() { return super.getPasswd();}//账户是否未过期,过期无法验证@Overridepublic 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@Overridepublic 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@Overridepublic boolean isCredentialsNonExpired() { return true;}//是否可用 ,禁用的用户不能身份验证@Overridepublic boolean isEnabled() { return true;}}

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); } }; }}

5、基础工作准备完成开始写controller

@Controllerpublic class LoginController { @Resourceprivate 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

@Componentpublic 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）

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Title</title></head><body><form action="/login" method="post"> 用户名 : <input type="text" name="username"/> 密码 : <input type="password" name="password"/> <input type="submit" value="登录"></form></body></html>

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); }
