Question

我有一个Spring Boot应用程序，当使用命令打包为独立jar时运行：

java -jar myApp.jar

但是，如果我的包装在pom.xml中是war，我就无法部署到tomcat服务器。我的应用程序是休息服务，提供休息呼叫。当我通过使用eclipse或通过java命令运行应用程序时，应用程序会响应其余的调用，例如：

http://www.spdev.ufu.br:8081/dashboard/rest/chart/getNumeroMetasPorUnidade

其他提供者是泽西岛。谁能告诉我为什么战争版本在tomcat中不起作用？我之前做了一些研究，但没有成功：

Spring Boot War deployed to Tomcat

这是我的pom.xml：

        </plugin>

这是我的泽西配置：

@Component
@ApplicationPath("/dashboard/rest")
public class JerseyConfig extends ResourceConfig {

public JerseyConfig() {

    packages("br.ufu.sp.dashboard.rest");
    packages("br.ufu.sp.dashboard.model");
    packages("br.ufu.sp.dashboard.repository");
    packages("br.ufu.sp.dashboard.service");

  }

}

和我的应用配置：

@SpringBootApplication
@EnableTransactionManagement
public class DashBoardApp extends SpringBootServletInitializer {

public static void main(String[] args) {
    new DashBoardApp().configure(new SpringApplicationBuilder(DashBoardApp.class)).run(args);
}


@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(DashBoardApp.class);
}

}

更新1：我检查了tomcat的日志，发现上下文无法初始化。以下是消息：

INFO: Spring WebApplicationInitializers detected on classpath: [br.ufu.sp.DashBoardApp@5a8d3b61, org.glassfish.jersey.server.spring.SpringWebApplicationInitializer@5ca8599b, org.springframework.boot.autoconfigure.jersey.JerseyAutoConfiguration@79d5f5ac] set 15, 2015 10:36:47 AM org.apache.catalina.core.ApplicationContext log
    INFO: Initializing Spring embedded WebApplicationContext set 15, 2015 10:36:53 AM org.apache.catalina.core.StandardContext listenerStart 
    SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
    java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml! at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:299)...

更新2：根据

https://java.net/jira/si/jira.issueviews:issue-html/JERSEY-2038/JERSEY-2038.html

需要一个类来设置上下文问题。无论如何，这不是现在的问题。不知怎的，我的端点没有被加载，如tomcat日志所示：

[DEBUG] 2015-09-15 11:14:30,278 org.springframework.boot.actuate.endpoint.mvc.EndpointHandlerMapping getHandlerInternal - Looking up handler method for path /rest/chart/getNumeroMetasPorUnidade
[DEBUG] 2015-09-15 11:14:30,284 org.springframework.boot.actuate.endpoint.mvc.EndpointHandlerMapping getHandlerInternal - Did not find handler method for [/rest/chart/getNumeroMetasPorUnidade]

Spring Boot jar文件应用程序运行但不是在部署到tomcat时
