1.首先看下我的项目结构

我们逐个讲解

/** * 用户登录配置类 * @author Administrator * */public class AdminUserDateils implements UserDetails { private static final long serialVersionUID = -1546619839676530441L; private transient YCAdmin yCAdmin; public AdminUserDateils() { } public AdminUserDateils(YCAdmin yCAdmin) { if (yCAdmin != null) { this.yCAdmin = yCAdmin; } } public YCAdmin getyCAdmin() { return yCAdmin; } public void setyCAdmin(YCAdmin yCAdmin) { this.yCAdmin = yCAdmin; } @Override public Collection<? extends GrantedAuthority> getAuthorities() { Collection<GrantedAuthority> authorities = new ArrayList<>(); SimpleGrantedAuthority authority = new SimpleGrantedAuthority("admin"); authorities.add(authority); return authorities; } //用户名密码 @Override public String getPassword() { return yCAdmin.getAdminPassword(); } //账号 @Override public String getUsername() { return yCAdmin.getAdminAccount(); } @Override public boolean isAccountNonExpired() { return true; } @Override public boolean isAccountNonLocked() { return true; } @Override public boolean isCredentialsNonExpired() { return true; } @Override public boolean isEnabled() { return true; }}

首先以上AdminUserDateils类是配置用户登录成功后，来存储用户登录的信息

/** * Spring-Security * @author Administrator * */@Servicepublic class AdminCustomerDetailsService implements UserDetailsService{ @Autowired private YCAdminMapper yCAdminMapper; @Override public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { YCAdmin ycAdmin= yCAdminMapper.selectYCAdminByAccount(username); if(ycAdmin==null) { throw new UsernameNotFoundException("未找到该用户！！"); } //配置的AdminUserDateils AdminUserDateils adminUserDateils = new AdminUserDateils(ycAdmin); return adminUserDateils; }}

以上AdminCustomerDetailsService是根据查找用户名的，需要实现UserDetailsService接口的loadUserByUsername的方法也就是会找用户名，这个根据mapper层，也就是数据库查找，返回只也就是刚才配置的AdminUserDateils类

public class YhPasswordEncoder implements PasswordEncoder{ @Override public String encode(CharSequence rawPassword) { return Des3.encrypt(rawPassword.toString()); } @Override public boolean matches(CharSequence rawPassword, String encodedPassword) { // TODO Auto-generated method stub return encode(rawPassword).equals(encodedPassword); }}

以上YhPasswordEncoder 需要继承是我们PasswordEncoder配置用户密码加密的，这里的加密可以按照自己业务需求来使用加密，按照这样换一种加密类型就可以了。

public class AdminSecurityConfiguration { @Configuration @Order(2) @EnableWebSecurity public static class ClientSecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private AdminCustomerDetailsService adminCustomerDetailsService; @Value("${yunhui.admin.urlContext:/houtai}") private String adminUrlContext; @Value("${yunhui.admin.noLoginUrls:}") private String noLoginUrls; @Override protected void configure(HttpSecurity http) throws Exception { //循环获取用户不需要验证url（这里是记录在yml） List<String> clientNoLoginUrls = new ArrayList<String>(); if (!noLoginUrls.isEmpty()) { for (String s : noLoginUrls.split(",")) { clientNoLoginUrls.add(adminUrlContext + s); } } http. //需要验证登录的url antMatcher(adminUrlContext + "/**").authorizeRequests() //不需登录验证的url .antMatchers(clientNoLoginUrls.toArray(new String[0])).permitAll() .anyRequest().authenticated().and() //开启表单验证 .formLogin(). //验证登录的url loginProcessingUrl("/houtai/login") //登录的页面 .loginPage("/houtai/login") //登录成功后跳转 .defaultSuccessUrl("/houtai").permitAll().and() //注销登录的url .logout().logoutUrl("/houtai/loginout") //注销之后跳转的页面 .logoutSuccessUrl("/houtai") .and().rememberMe().and().csrf().disable();; } @Override public void configure(AuthenticationManagerBuilder auth) throws Exception { //需要哪个service，和验证密码的方式，刚才我们都配置了 auth.userDetailsService(adminCustomerDetailsService).passwordEncoder(new YhPasswordEncoder()); }}

最后就是配置首先开启
@Configuration
@EnableWebSecurity
的注解

一个是我们刚才配置的service
其他两个两个变量是在配置文件配置的

最后配置我们表单验证就可以了input的name必须是username和password，除非重新配置了，
action="/houtai/login"就是直接这样就可以实现登录了

如果有HttpSecurity配置的细节问题可以提问

补充可以自己配置登录成功和失败类
