我尝试使用此答案中的代码将多租户添加到我的spring boot 1.2.5:
Setting up a MultiTenantConnectionProvider using Hibernate 4.2 and Spring 3.1.1
我得到以下异常:
Caused by: java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
at org.springframework.web.context.request.RequestContextHolder.currentRequestAttributes(RequestContextHolder.java:131)
at org.springframework.web.context.request.AbstractRequestAttributesScope.get(AbstractRequestAttributesScope.java:41)
at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:337)
上述答案的源代码是:
@Component
@Scope(value = "request", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class RequestURITenantIdentifierResolver implements CurrentTenantIdentifierResolver {
@Autowired
private HttpServletRequest request;
@Override
public String resolveCurrentTenantIdentifier() {
String[] pathElements = request.getRequestURI().split("/");
String tenant = pathElements[1];
return tenant;
}
@Override
public boolean validateExistingCurrentSessions() {
return true;
}
}
我尝试将范围值更改为原型:
@Scope(value = "prototype", proxyMode = ScopedProxyMode.TARGET_CLASS)
在我尝试在我的JpaRepository中使用@Query之前一直正常工作,例如:
@Query("From Order where orderId = :id")
public Order joinWithPurchaseItems(@Param("id") Integer id);
并抛出相同的异常:
Caused by: java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
at org.springframework.web.context.request.RequestContextHolder.currentRequestAttributes(RequestContextHolder.java:131)
at org.springframework.web.context.request.AbstractRequestAttributesScope.get(AbstractRequestAttributesScope.java:41)
at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:337)
有趣的是,使用本机查询不会抛出此异常。
我还尝试在Application类中使用RequestContextListener但没有成功:
@SpringBootApplication
public class Application {
@Bean
@ConditionalOnMissingBean(RequestContextListener.class)
public RequestContextListener requestContextListener() {
return new RequestContextListener();
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
感谢任何帮助。

正如评论中所建议的,我使用了过滤器,并从那里捕获了URL。解析器从过滤器设置的静态字段中捕获模式名称。
