Question

我正在尝试在春季添加网络安全性，但我不希望过滤器适用于某些事情。如何在java中完成？

也许有更好的方法可以做到这一点，因为我创建了一个自定义过滤器，但这是我认为实例化它的唯一方法，因为它的依赖性。

总的来说，我想做的是：

/resources/**不应该通过过滤器， /login（POST）不应该通过过滤器，其他一切应该通过过滤器

通过我在春天发现的各种例子我能够想出一个开始，但它显然不起作用：

@Configuration
@EnableWebSecurity
@Import(MyAppConfig.class)
public class MySecurityConfig extends WebSecurityConfigurerAdapter
{
    @Override
    public void configure(WebSecurity webSecurity) throws Exception
    {
        webSecurity.ignoring().antMatchers("/resources/**");
    }

    @Override
    public void configure(HttpSecurity httpSecurity) throws Exception
    {
        httpSecurity
                .authorizeRequests()
                .antMatchers("/resources/**").permitAll()
                .antMatchers("/login").permitAll();

        httpSecurity.httpBasic();
        httpSecurity.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

    @Bean
    @Autowired
    public TokenFilterSecurityInterceptor<TokenInfo> tokenInfoTokenFilterSecurityInterceptor(MyTokenUserInfoCache userInfoCache, ServerStatusService serverStatusService, HttpSecurity httpSecurity) throws Exception
    {
        TokenService<TokenInfo> tokenService = new TokenServiceImpl(userInfoCache);
        TokenFilterSecurityInterceptor<TokenInfo> tokenFilter = new TokenFilterSecurityInterceptor<TokenInfo>(tokenService, serverStatusService, "RUN_ROLE");
        httpSecurity.addFilter(tokenFilter);
        return tokenFilter;
    }
}

您是否对所有Spring Security忽略URL感兴趣，或者您是否只希望该特定过滤器忽略该请求？如果您希望所有Spring Security都忽略该请求，可以使用以下命令完成：

@Configuration
@EnableWebSecurity
@Import(MyAppConfig.class)
public class MySecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private MyTokenUserInfoCache userInfoCache;
    @Autowired
    private ServerStatusService serverStatusService;

    @Override
    public void configure(WebSecurity webSecurity) throws Exception
    {
        webSecurity
            .ignoring()
                // All of Spring Security will ignore the requests
                .antMatchers("/resources/**")
                .antMatchers(HttpMethod.POST, "/login");
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .addFilter(tokenInfoTokenFilterSecurityInterceptor())
            .authorizeRequests()
                // this will grant access to GET /login too do you really want that?
                .antMatchers("/login").permitAll()
                .and()
            .httpBasic().and()
            .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

    @Bean
    public TokenFilterSecurityInterceptor<TokenInfo> tokenInfoTokenFilterSecurityInterceptor() throws Exception
    {
        TokenService<TokenInfo> tokenService = new TokenServiceImpl(userInfoCache);
        return new TokenFilterSecurityInterceptor<TokenInfo>(tokenService, serverStatusService, "RUN_ROLE");
    }
}

如果您只想让特定的过滤器忽略特定请求，您可以执行以下操作：

@Configuration
@EnableWebSecurity
@Import(MyAppConfig.class)
public class MySecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private MyTokenUserInfoCache userInfoCache;
    @Autowired
    private ServerStatusService serverStatusService;

    @Override
    public void configure(WebSecurity webSecurity) throws Exception
    {
        webSecurity
            .ignoring()
                // ... whatever is here is ignored by All of Spring Security
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .addFilter(tokenInfoTokenFilterSecurityInterceptor())
            .authorizeRequests()
                // this will grant access to GET /login too do you really want that?
                .antMatchers("/login").permitAll()
                .and()
            .httpBasic().and()
            .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

    @Bean
    public TokenFilterSecurityInterceptor<TokenInfo> tokenInfoTokenFilterSecurityInterceptor() throws Exception
    {
        TokenService<TokenInfo> tokenService = new TokenServiceImpl(userInfoCache);
        TokenFilterSecurityInterceptor tokenFilter new TokenFilterSecurityInterceptor<TokenInfo>(tokenService, serverStatusService, "RUN_ROLE");


        RequestMatcher resourcesMatcher = new AntPathRequestMatcher("/resources/**");
        RequestMatcher posLoginMatcher = new AntPathRequestMatcher("/login", "POST");
        RequestMatcher ignored = new OrRequestMatcher(resourcesMatcher, postLoginMatcher);
        return new DelegateRequestMatchingFilter(ignored, tokenService);
    }
}


public class DelegateRequestMatchingFilter implements Filter {
    private Filter delegate;
    private RequestMatcher ignoredRequests;

    public DelegateRequestMatchingFilter(RequestMatcher matcher, Filter delegate) {
        this.ignoredRequests = matcher;
        this.delegate = delegate;
    }

    public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) {
         HttpServletRequest request = (HttpServletRequest) req;
         if(ignoredRequests.matches(request)) {
             chain.doFilter(req,resp,chain);
         } else {
             delegate.doFilter(req,resp,chain);
         }
    }
}

1在spring-security的xml配置中我使用

<http pattern="/resources/**" security="none"/> 

<http use-expressions="true">
<intercept-url pattern="/login" access="permitAll"/> 
</http>

从安全检查中检索它。

2之后在弹簧配置中添加mvc:resource标签

<mvc:resources mapping="/resource/**" location="/resource/"/>

重要提示：此配置仅在调度程序servlet处理url时有效。这意味着在web.xml中你必须有

   <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

在java配置中添加http安全过滤器
