如何通过 XML 配置仅针对特定 URL 模式在 Spring Security 4 中禁用 CSRF?

How to disable CSRF in Spring Security 4 only for specific URL pattern through XML configuration?

Spring-security.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>

如果我只使用一个 security:http 块，我的代码工作正常，但在我添加另一个块后，它会引发如下错误:

My code works fine if I use only one security:http block, but after I add another block it throws error as below:

错误

推荐答案

仅通过 XML 更改无法实现.以下为我工作

Could not achieve with just XML changes. Below worked for me

Spring-security.xml

<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

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);
    }
}
