如何在Spring Security 4中通过XML配置仅对特定URL模式禁用CSRF？

Spring安全。xml

<security:http auto-config="true" use-expressions="true" pattern="/ext/**">
    <csrf disabled="true" />
</security:http>

<security:http auto-config="true" use-expressions="true" authentication-manager-ref="authenticationManager">
    <security:intercept-url pattern="/auth/**" access="hasAnyRole('ROLE_USER')" />
    <security:form-login login-page="/login" authentication-success-handler-ref="loginSuccessHandler" authentication-failure-url="/login" login-processing-url="/j_spring_security_check" />
    <security:logout invalidate-session="true" logout-url="/logout" success-handler-ref="logoutSuccessHandler" />
</security:http>

我的代码工作正常，如果我只使用一个安全：http块，但在我添加另一个块后，它抛出错误如下：

错误

Answer 1

您可以有两个（或更多）过滤器链：

<http pattern="/your-specific/**">
  <!-- ... -->
  <csrf disabled="true"/>
</http>
<http>
  <!-- ... -->
</http>

Answer 2

仅通过XML更改无法实现。下面是我的工作

Spring-security.xml变化

<security:http  use-expressions="true" authentication-manager-ref="authenticationManager">
    <security:intercept-url pattern="/auth/**" access="hasAnyRole('ROLE_USER')" />
    <security:form-login login-page="/login" authentication-success-handler-ref="loginSuccessHandler" authentication-failure-url="/login" login-processing-url="/j_spring_security_check" />
    <security:logout invalidate-session="true" logout-url="/logout" success-handler-ref="logoutSuccessHandler" />

    <security:csrf request-matcher-ref="csrfSecurityRequestMatcher"  />
</security:http>

CsrfSecurityRequestMatcher

public class CsrfSecurityRequestMatcher implements RequestMatcher {
    private Pattern allowedMethods = Pattern.compile("^(GET|HEAD|TRACE|OPTIONS)$");
    private RegexRequestMatcher unprotectedMatcher = new RegexRequestMatcher("/ext/**", null);

    @Override
    public boolean matches(HttpServletRequest request) {          
        if(allowedMethods.matcher(request.getMethod()).matches()){
            return false;
        }
        return !unprotectedMatcher.matches(request);
    }
}
