java - tomcat中的应用程序未部署

Question

经过研究后，我没有运气，因此我在这里发帖。我计划在单个 Tomcat 7 中运行两个 java 应用程序(使用 Spring)。这意味着 本地主机:8080/app1 和本地主机:8080/app2。当我将两个应用程序部署为 .war 文件时，app1 可以工作，而 app2 则不能。如果 App2 作为单个 spring 应用程序从 Eclipse 运行并且打包设置为 jar，则它可以完美运行。

尝试部署 App2 时 Tomcat 向我报告的错误是:

    ERROR org.springframework.web.context.ContextLoader - Context initialization failed

我研究了未创建 bean 的错误，我不知道发生了什么。类和最可能有问题的 bean:

@Configuration
@ImportResource({ "classpath:cxf.xml" })
public class Config {

    @Autowired
    private Bus cxfBus;

    @Autowired
    private UserServiceSoapImpl userServiceSoapImpl;

    @Bean
    public EndpointImpl UserServiceSoap() {
        EndpointImpl endpoint = new EndpointImpl(cxfBus, userServiceSoapImpl);
        return endpoint;
    }

    @Bean
    public static PropertySourcesPlaceholderConfigurer placeHolderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }

}

我还在使用 Apache CXF 3.1.12。

提前致谢。

请将cxf.xml导入为@ImportResource("classpath:META-INF/cxf/cxf.xml")并确保何时生成warcxf-core.jar 也随 war 一起提供。(第二种情况很可能是原因，我相信您已经显式添加了 cxf 框架来构建库，并且不是打包的一部分)。
