无法在 Spring Boot 中使用 spring-integration 安全性

Question

我正在尝试通过以下方式在 Spring Boot 应用程序中使用 Spring Integration Security 配置：

<si-security:secured-channels access-decision-manager=
"accessDecisionManager">
    <si-security:access-policy pattern="requestChannel" receive-access="ROLE_USER"/>
</si-security:secured-channels>

此 XML 配置被插入到以下配置类中：

package demo.security.config;

import java.util.Arrays;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.integration.config.EnableIntegration;
import org.springframework.security.access.AccessDecisionManager;
import org.springframework.security.access.AccessDecisionVoter;
import org.springframework.security.access.vote.AffirmativeBased;
import org.springframework.security.access.vote.RoleVoter;

@Configuration
@EnableIntegration
// mentioned Spring Integration Security Config causing
// java.lang.IllegalArgumentException: A ServletContext is required to
// configure default servlet handling
@ImportResource({"classpath:springIntegrationSecurity.xml"})
public class SpringIntegrationSecurity {

@SuppressWarnings("rawtypes")
@Bean
public AccessDecisionManager accessDecisionManager() {
    RoleVoter roleVoter = new RoleVoter(); 
    roleVoter.setRolePrefix("");
    final AffirmativeBased acd = new AffirmativeBased(Arrays.<AccessDecisionVoter> 
        asList(roleVoter));
    return acd;
}

}

如果我在我的应用程序中包含提到的 Spring Integration Security XML 配置，它会崩溃：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultServletHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'defaultServletHandlerMapping' threw exception; nested exception is java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling

似乎Spring Security Integration config是在ServletContext之前加载的，但我不知道如何克服这个问题...:(

有人可以帮忙吗？如果我省略 Spring Integration Security，我的应用程序可以正常工作...

Answer 1

问题可能与@ImportResource 解析的顺序有关。这就是为什么在大多数情况下 Spring Boot 都需要 Java Config。

例如，您的 Spring Integration Security 案例可以表示为：

@Bean
@SecuredChannel(interceptor = "channelSecurityInterceptor", receiveAccess = "ROLE_USER")
public MessageChannel requestChannel() {
    return new DirectChannel();
}

@Bean
public ChannelSecurityInterceptor channelSecurityInterceptor(AuthenticationManager authenticationManager,
                AccessDecisionManager accessDecisionManager) {
    ChannelSecurityInterceptor channelSecurityInterceptor = new ChannelSecurityInterceptor();
    channelSecurityInterceptor.setAuthenticationManager(authenticationManager);
    channelSecurityInterceptor.setAccessDecisionManager(accessDecisionManager);
    return channelSecurityInterceptor;
}

另一方面，请与您使用的 Spring Boot 和 Spring Integration 版本分享。

您介意用最新的 Spring Boot 1.3 M5 检查一下吗？
