web.xml检查过没有ContextLoaderListener,ContextLoaderListener和RequestContextListener写在代码中

@Configuration
public class ListenerConfig {

    /**
     * 配置 RequestContextListener
     * @return
     */
    @Bean
    public ServletListenerRegistrationBean<RequestContextListener> listenerRegistration1() {
        return new ServletListenerRegistrationBean<>(
            new RequestContextListener());
    }

    /**
     * 配置 ContextLoaderListener
     * @return
     */
    @Bean
    public  ServletListenerRegistrationBean<ContextLoaderListener> listenerRegistration2(){
        return new ServletListenerRegistrationBean<>(
            new ContextLoaderListener()
        );
    }
}

Spring boot war 包部署远程tomcat ,部署第一个项目没问题,部署第二个就启动不了了,然后把第一个项目stop ,第二个就可以start 了,就是只能启动一个,不知道什么原因,求大神们解答![图片说明](https://img-ask.csdn.net/upload/201705/05/1493999537_901865.png)![图片说明](https://img-ask.csdn.net/upload/201705/05/1493999544_746128.png)

基于maven构建的spring boot项目启动加载问题

问题: spring boot 子项目启动加载错误。 详情描述: eclipse 开发 的maven工程包含十个左右的子项目。其中有两个项目, 一个是基于redis存储session的web前台展示模块,一个是对应的但没有redis做中间件的后台管理模块。 为啥启动后台管理模块的时候会关联到web前台项目的controllor呢,这样启动后台报redis配置的错误。
