</dependencyManagement>1.2 创建SimpleUserDetailsService 实现 UserDetailsService接口
作用：将数据查到的用户信息和权限放进UserDetails对象，用于SpringSecurity进行认证
@Component
@Slf4j
public class SimpleUserDetailsService implements UserDetailsService {
@Autowired
private UserService userService;
private final PasswordEncoder passwordEncoder;
public SimpleUserDetailsService(PasswordEncoder passwordEncoder) {
this.passwordEncoder = passwordEncoder;
}
@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
//从数据库获取用户信息
UserEntity userEntity = userService.getByUsername(s);
//从数据库获取用户的角色权限
List<UserRoles> userRolesList = userService.getRolesByUsername(s);
StringBuilder authorityBuilder = new StringBuilder();
//将角色信息放进StringBuilder中
userRolesList.forEach(r-> {
authorityBuilder.append("ROLE_").append(r.getRoleName().toUpperCase()).append(",");
//从数据库获取用户资源权限
List<RolePermissions> permissionsList = userService.getPermissionsByRole(r.getRoleName());
permissionsList.forEach(p->authorityBuilder.append(p.getPermission()).append(","));
});
//获取用户密码
String password = userEntity.getPassword();
log.info("password->"+password);
log.info("authorities->"+authorityBuilder.toString());
//返回UserDetails对象
return new User(s,passwordEncoder.encode(password), AuthorityUtils.commaSeparatedStringToAuthorityList(authorityBuilder.toString()));
}
}1.3 创建JWTAuthenticationSuccessHandler 实现 AuthenticationSuccessHandler接口
作用：自定义登录成功请求返回的结果，SpringSecurity默认登录成功后跳转到登录前url或者"/"，前后端分离项目需要登录成功后返回jwt-token
@Component
public class JWTAuthenticationSuccessHandler implements AuthenticationSuccessHandler {
//json
private final ObjectMapper objectMapper = new ObjectMapper();
//操作redis
private final HashOperations<String, String, String> operations;
// 构造注入
public JWTAuthenticationSuccessHandler(RedisTemplate<String, String> redisTemplate) {
this.operations = redisTemplate.opsForHash();
}
@Override
public void onAuthenticationSuccess(HttpServletRequest req, HttpServletResponse resp,
Authentication authentication)
throws IOException, ServletException {
// authentication 对象携带了当前登陆用户名等相关信息
User user = (User) authentication.getPrincipal();
resp.setContentType("application/json;charset=UTF-8");
try {
StringBuffer buffer = new StringBuffer();
user.getAuthorities().forEach(item -> {
buffer.append(item.getAuthority());
buffer.append(",");
});
buffer.deleteCharAt(buffer.length()-1);
// 用户的 username 和他所具有的权限存入 redis 中。
operations.put(JWTUtil.REDIS_HASH_KEY, user.getUsername(), buffer.toString());
// 在 jwt-token-string 的荷载（payload）中存上当前用户的名字.
String jwtStr = JWTUtil.createJWT(user.getUsername());
Map<String, String> map = new HashMap<>();
map.put("code", "10000");
map.put("msg", "success");
map.put("jwt-token", jwtStr);
PrintWriter out = resp.getWriter();
out.write(objectMapper.writeValueAsString(map));
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}1.4 配置SpringSecurity，将JWTAuthenticationSuccessHandler的返回结果替换默认返回结果
@EnableWebSecurity(debug = false)
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Resource
private SimpleUserDetailsService userDetailsService;
@Resource
private JWTAuthenticationSuccessHandler successHandler;
@Bean
public PasswordEncoder passwordEncoder() {
return NoOpPasswordEncoder.getInstance(); // 这是一个空的、假的密码加密器。在加密时啥事没干。
}
@Override
protected void configure(HttpSecurity http) throws Exception {
//任何请求都需要认证
http.authorizeRequests().anyRequest().authenticated();
//登录框登录,登录成功后使用自定义的JWTAuthenticationSuccessHandler
http.formLogin().successHandler(successHandler);
//禁用跨域过滤器
http.csrf().disable();
//禁用session过滤器
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService)
.passwordEncoder(passwordEncoder());
}
}1.5 将服务注册进nacos
- 启动类上添加@EnableDiscoveryClient注解
@SpringBootApplication @EnableDiscoveryClient public class AuthenticationServiceApplication { public static void main(String[] args) { SpringApplication.run(AuthenticationServiceApplication.class, args); } } - 配置bootstrap.yml

@Slf4j
@Component
public class JwtFilter extends OncePerRequestFilter {
//操作redis
private final HashOperations<String, String, String> operations;
//构造注入
public JwtFilter(RedisTemplate<String, String> redisTemplate) {
this.operations = redisTemplate.opsForHash();
}
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
FilterChain filterChain) throws ServletException, IOException {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
//如果security_context_holder中有authentication
if(authentication != null){
log.info("security_context_holder中有authentication");
filterChain.doFilter(request,response);
return;
}
// String jwtStr = request.getHeader("x-jwt-token");
String username = request.getHeader("x-username");
//如果请求头里没有token
if(StringUtils.isEmpty(username)){
log.info("没有username");
filterChain.doFilter(request,response);
return;
}
//jwtStr验证不通过
/*if(!JwtUtils.verify(jwtStr)){
log.info("jwtStr验证不通过");
filterChain.doFilter(request,response);
return;
}
String username = JwtUtils.getUsernameFromJWT(jwtStr);*/
//根据用户名从redis中获取权限
log.info("username->"+username);
String authorities = operations.get("jwt-token",username);
log.info("authorities->"+operations.get("jwt-token",username));
//将权限存进token中
UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(
username, null, AuthorityUtils.commaSeparatedStringToAuthorityList(authorities));
SecurityContextHolder.getContext().setAuthentication(authenticationToken);
filterChain.doFilter(request,response);
}
}2.3 配置SpringSecurity，将自定义的JwtFilter过滤器添加进SpringSecurity过滤器链
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Resource
private JwtFilter jwtFilter;
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().anyRequest().authenticated()
.and()
//将自定义的Jwt过滤器添加到UsernamePasswordAuthenticationFilter后面
.formLogin().and().addFilterAfter(jwtFilter, UsernamePasswordAuthenticationFilter.class);
}
}2.4 将服务注册到Nacos
