我遇到了一种情况,我正在使用Spring MVC(jsp,控制器,服务,dao)和基于会话的身份验证。但是现在我很少将这些URL用作用于集成目的的RESTful Web服务。
仅对于那些请求,我需要使用基于令牌(例如JWT)的身份验证。
因此,是否有可能在同一项目中同时使用两种身份验证。
答案 0 :(得分:2)
我有可能在同一项目中同时使用两种身份验证。
可以。通过具有两个身份验证处理过滤器。
过滤器-1 :用于Rest API(JwtAuthTokenFilter),该API应该是无状态的,并由每次请求中发送的授权令牌标识。
过滤器-2 :您需要另一个过滤器(UsernamePasswordAuthenticationFilter)默认情况下,如果您通过http.formLogin()
配置它,spring-security将提供此过滤器。在此,每个请求都由关联的会话(JSESSIONID
cookie)标识。如果请求不包含有效的会话,则它将被重定向到身份验证入口点(例如:login-page)。
api-url-pattern = "/api/**"
webApp-url-pattern = "/**"
工作方式
带有/api/**
的URL将通过JwtAuthTokenFilter
传递,在那里它将读取令牌,如果它具有有效的令牌,则设置身份验证对象并继续进行链接。如果没有有效的请求,则链会断开,并且将以401(未授权)状态发送响应。
/api/**
以外的 URL将由UsernamePasswordAuthenticationFilter
处理[这是.formLogin()
配置所配置的spring security中的默认设置],它将检查有效的会话,如果没有包含它将重定向到配置的logoutSuccessUrl的有效会话。
如何配置注意: 您的Webapp无法使用现有会话访问API。您可以使用Jwt令牌从Web应用程序访问API。
要实现两个不同的身份验证处理过滤器,
您应该以不同的顺序配置多个http安全性配置
可以通过在安全配置类中声明静态类来配置多个http安全配置,如下所示。
(即使OP要求在概念上明智地提出代码,也可能会有所帮助。)
@Configuration
@EnableWebSecurity
@ComponentScan(basePackages = "com.gmail.nlpraveennl")
public class SpringSecurityConfig
{
@Bean
public PasswordEncoder passwordEncoder()
{
return new BCryptPasswordEncoder();
}
@Configuration
@Order(1)
public static class RestApiSecurityConfig extends WebSecurityConfigurerAdapter
{
@Autowired
private JwtAuthenticationTokenFilter jwtauthFilter;
@Override
protected void configure(HttpSecurity http) throws Exception
{
http
.csrf().disable()
.antMatcher("/api/**")
.authorizeRequests()
.antMatchers("/api/authenticate").permitAll()
.antMatchers("/api/**").hasAnyRole("APIUSER")
.and()
.addFilterBefore(jwtauthFilter, UsernamePasswordAuthenticationFilter.class);
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
}
@Configuration
@Order(2)
public static class LoginFormSecurityConfig extends WebSecurityConfigurerAdapter
{
@Autowired
private PasswordEncoder passwordEncoder;
@Autowired
public void configureInMemoryAuthentication(AuthenticationManagerBuilder auth) throws Exception
{
auth.inMemoryAuthentication().withUser("admin").password(passwordEncoder.encode("admin@123#")).roles("ADMIN");
}
@Override
protected void configure(HttpSecurity http) throws Exception
{
http
.csrf().disable()
.antMatcher("/**").authorizeRequests()
.antMatchers("/resources/**").permitAll()
.antMatchers("/**").hasRole("ADMIN")
.and().formLogin();
http.sessionManagement().maximumSessions(1).expiredUrl("/customlogin?expired=true");
}
}
}
Jwt身份验证令牌过滤器
@Component
public class JwtAuthenticationTokenFilter extends OncePerRequestFilter
{
@Autowired
private JwtTokenUtil jwtTokenUtil;
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws ServletException, IOException
{
final String header = request.getHeader("Authorization");
if (header != null && header.startsWith("Bearer "))
{
String authToken = header.substring(7);
System.out.println(authToken);
try
{
String username = jwtTokenUtil.getUsernameFromToken(authToken);
if (username != null && SecurityContextHolder.getContext().getAuthentication() == null)
{
if (jwtTokenUtil.validateToken(authToken, username))
{
List<GrantedAuthority> authList = new ArrayList<>();
authList.add(new SimpleGrantedAuthority("ROLE_APIUSER"));
UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = new UsernamePasswordAuthenticationToken(username, null, authList);
usernamePasswordAuthenticationToken.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
SecurityContextHolder.getContext().setAuthentication(usernamePasswordAuthenticationToken);
}
}
}
catch (Exception e)
{
System.out.println("Unable to get JWT Token, possibly expired");
}
}
chain.doFilter(request, response);
}
}
Jwt令牌实用程序类
@Component
public class JwtTokenUtil implements Serializable
{
private static final long serialVersionUID = 8544329907338151549L;
public static final long JWT_TOKEN_VALIDITY = 5 * 60 * 60;
private String secret = "my-secret";
public String getUsernameFromToken(String token)
{
return getClaimFromToken(token, Claims::getSubject);
}
public Date getExpirationDateFromToken(String token)
{
return getClaimFromToken(token, Claims::getExpiration);
}
public <T> T getClaimFromToken(String token, Function<Claims, T> claimsResolver)
{
final Claims claims = getAllClaimsFromToken(token);
return claimsResolver.apply(claims);
}
private Claims getAllClaimsFromToken(String token)
{
return Jwts.parser().setSigningKey(secret).parseClaimsJws(token).getBody();
}
private Boolean isTokenExpired(String token)
{
final Date expiration = getExpirationDateFromToken(token);
return expiration.before(new Date());
}
public String generateToken(String username)
{
Map<String, Object> claims = new HashMap<>();
return doGenerateToken(claims, username);
}
private String doGenerateToken(Map<String, Object> claims, String subject)
{
return "Bearer "+Jwts.builder().setClaims(claims).setSubject(subject).setIssuedAt(new Date(System.currentTimeMillis()))
.setExpiration(new Date(System.currentTimeMillis() + JWT_TOKEN_VALIDITY * 1000)).signWith(SignatureAlgorithm.HS512, secret).compact();
}
public Boolean validateToken(String token, String usernameFromToken)
{
final String username = getUsernameFromToken(token);
return (username.equals(usernameFromToken) && !isTokenExpired(token));
}
}
调度程序Servlet配置
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.gmail.nlpraveennl") //Do not skip componentscan
public class ServletConfiguration implements WebMvcConfigurer
{
@Bean
public ViewResolver configureViewResolver()
{
InternalResourceViewResolver viewResolve = new InternalResourceViewResolver();
viewResolve.setPrefix("/WEB-INF/jsp/");
viewResolve.setSuffix(".jsp");
return viewResolve;
}
@Bean
public ResourceBundleMessageSource messageSource()
{
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("messages");
messageSource.setDefaultEncoding("UTF-8");
messageSource.setUseCodeAsDefaultMessage(true);
return messageSource;
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry)
{
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
}
以上解释是一种实现方式,我在my another answer which you can refer here中解释了另一种实现方式(其中REST API可以通过身份验证令牌以及会话进行访问)
