本篇文章給大家分享的是有關怎么在Spring Boot 2中利用Spring security 與JWT登錄微信小程序,小編覺得挺實用的,因此分享給大家學習,希望大家閱讀完這篇文章后可以有所收獲,話不多說,跟著小編一起來看看吧。
登錄
通過自定義的WxAppletAuthenticationFilter替換默認的UsernamePasswordAuthenticationFilter,在UsernamePasswordAuthenticationFilter中可任意定制自己的登錄方式。
需要結合JWT來實現用戶認證,第一步登錄成功后如何頒發token。
public class CustomAuthenticationSuccessHandler implements AuthenticationSuccessHandler {
@Autowired
private JwtTokenUtils jwtTokenUtils;
@Override
public void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
// 使用jwt管理,所以封裝用戶信息生成jwt響應給前端
String token = jwtTokenUtils.generateToken(((WxAppletAuthenticationToken)authentication).getOpenid());
Map<String, Object> result = Maps.newHashMap();
result.put(ConstantEnum.AUTHORIZATION.getValue(), token);
httpServletResponse.setContentType(ContentType.JSON.toString());
httpServletResponse.getWriter().write(JSON.toJSONString(result));
}
}第二步,棄用spring security默認的session機制,通過token來管理用戶的登錄狀態。這里有倆段關鍵代碼。
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf()
.disable()
.sessionManagement()
// 不創建Session, 使用jwt來管理用戶的登錄狀態
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
......;
}第二步,添加token的認證過濾器。
public class JwtAuthenticationTokenFilter extends OncePerRequestFilter {
@Autowired
private AuthService authService;
@Autowired
private JwtTokenUtils jwtTokenUtils;
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
log.debug("processing authentication for [{}]", request.getRequestURI());
String token = request.getHeader(ConstantEnum.AUTHORIZATION.getValue());
String openid = null;
if (token != null) {
try {
openid = jwtTokenUtils.getUsernameFromToken(token);
} catch (IllegalArgumentException e) {
log.error("an error occurred during getting username from token", e);
throw new BasicException(ExceptionEnum.JWT_EXCEPTION.customMessage("an error occurred during getting username from token , token is [%s]", token));
} catch (ExpiredJwtException e) {
log.warn("the token is expired and not valid anymore", e);
throw new BasicException(ExceptionEnum.JWT_EXCEPTION.customMessage("the token is expired and not valid anymore, token is [%s]", token));
}catch (SignatureException e) {
log.warn("JWT signature does not match locally computed signature", e);
throw new BasicException(ExceptionEnum.JWT_EXCEPTION.customMessage("JWT signature does not match locally computed signature, token is [%s]", token));
}
}else {
log.warn("couldn't find token string");
}
if (openid != null && SecurityContextHolder.getContext().getAuthentication() == null) {
log.debug("security context was null, so authorizing user");
Account account = authService.findAccount(openid);
List<Permission> permissions = authService.acquirePermission(account.getAccountId());
List<SimpleGrantedAuthority> authorities = permissions.stream().map(permission -> new SimpleGrantedAuthority(permission.getPermission())).collect(Collectors.toList());
log.info("authorized user [{}], setting security context", openid);
SecurityContextHolder.getContext().setAuthentication(new WxAppletAuthenticationToken(openid, authorities));
}
filterChain.doFilter(request, response);
}
}第一步,開啟注解@EnableGlobalMethodSecurity。
@SpringBootApplication
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class JwtSpringSecurityDemoApplication {
public static void main(String[] args) {
SpringApplication.run(JwtSpringSecurityDemoApplication.class, args);
}
}第二部,在需要鑒權的接口上添加@PreAuthorize注解。
@RestController
@RequestMapping("/test")
public class TestController {
@GetMapping
@PreAuthorize("hasAuthority('user:test')")
public String test(){
return "test success";
}
@GetMapping("/authority")
@PreAuthorize("hasAuthority('admin:test')")
public String authority(){
return "test authority success";
}
