我有一个设置，我需要在其中进行租户感知的身份验证和授权。

@Order(Ordered.LOWEST_PRECEDENCE - 100)
public class TenantFilter extends OncePerRequestFilter {
    private static final Logger logger = LoggerFactory.getLogger(TenantFilter.class);
    private static final String TENANT_HEADER = "X-Tenant"; 
    private static final String CONNECTION_STRING = "ObfuscatedConnectionString";
    private static final String TENANT_REPLACEMENT = "TENANT";
    @Override
    protected void doFilterInternal (HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        String dbConnectionString = CONNECTION_STRING.replace(TENANT_REPLACEMENT, "");
        ConnectionStorage.setConnection(dbConnectionString);
        filterChain.doFilter(request, response);
        ConnectionStorage.clear();
    }
}

虽然我知道有一些地方可以改进，但这只是一个占位符，以便能够测试该机制。2实际的实现将在后面进行。3当在不需要添加JWT的情况下进行测试时，它可以按预期工作，并且在给定正确的前提条件的情况下根据请求切换承租人。
但是，我不想在每个请求上都发送用户名+密码，而想在混合中添加一个JWT。

public class JwtAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
    private static final Logger logger = LoggerFactory.getLogger(JwtAuthenticationFilter.class);
    private AuthenticationManager authenticationManager;
    public JwtAuthenticationFilter (AuthenticationManager authenticationManager) {
        this.authenticationManager = authenticationManager;
    }
    @Override
    public Authentication attemptAuthentication (HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        logger.info("Attempting authentication");
        try {
            UserRequest creds = new ObjectMapper()
                .readValue(request.getInputStream(), UserRequest.class);
            return authenticationManager.authenticate(
                new UsernamePasswordAuthenticationToken(
                    creds.getUsername(),
                    creds.getPassword(),
                    new ArrayList<>())
            );
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
    @Override
    protected void successfulAuthentication (HttpServletRequest request, HttpServletResponse response, FilterChain chain, Authentication auth) throws IOException, ServletException {
        logger.info("Authentication successful");
        String token = JWT.create()
            .withSubject(((User) auth.getPrincipal()).getUsername())
            .withExpiresAt(new Date(System.currentTimeMillis() + (JWTConstants.ACCESS_TOKEN_VALIDITY_SECONDS * 1000)))
            .sign(Algorithm.HMAC512(JWTConstants.SIGNING_KEY.getBytes()));
        response.addHeader(JWTConstants.HEADER_STRING, JWTConstants.TOKEN_PREFIX + token);
    }
}

和

public class JwtAuthorizationFilter extends BasicAuthenticationFilter {
    private static final Logger logger = LoggerFactory.getLogger(JwtAuthorizationFilter.class);
    public JwtAuthorizationFilter (AuthenticationManager authenticationManager) {
        super(authenticationManager);
    }
    @Override
    protected void doFilterInternal (HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws IOException, ServletException {
        logger.info("Doing filter internal");
        String header = request.getHeader(JWTConstants.HEADER_STRING);
        if (header == null || !header.startsWith(JWTConstants.TOKEN_PREFIX)) {
            chain.doFilter(request, response);
            return;
        }
        UsernamePasswordAuthenticationToken authentication = getAuthentication(request);
        SecurityContextHolder.getContext().setAuthentication(authentication);
        chain.doFilter(request, response);
    }
    private UsernamePasswordAuthenticationToken getAuthentication (HttpServletRequest request) {
        String token = request.getHeader(JWTConstants.HEADER_STRING);
        if (token != null) {
            // parse the token.
            String user = JWT.require(Algorithm.HMAC512(JWTConstants.SIGNING_KEY.getBytes()))
                .build()
                .verify(token.replace(JWTConstants.TOKEN_PREFIX, ""))
                .getSubject();
            if (user != null) {
                return new UsernamePasswordAuthenticationToken(user, null, new ArrayList<>());
            }
            return null;
        }
        return null;
    }
}

为我的请求提供身份验证。在/api/user/login中有一个用户名和密码，还有一个jwt标记用于其他所有内容。
然而，看起来好像首先执行安全过滤器，并且我的承租人过滤器对于设置要转到的正确DB的connectionstring相当重要。
