我有一個包含嵌入式Tomcat的Spring應用程序。作爲可執行的戰爭，它工作正常。因爲我將使用AngularJ作爲前端，因此將Spring項目放在可執行jar文件中並不實際，因爲我將在瀏覽器中進行調試，並希望能夠快速編輯js源文件。如果他們被保存在檔案中，這是煩人的。在tomcat上部署的Spring引導將無法啓動
這就是爲什麼我想讓它可部署，所以它會解包到tomcat上。這似乎很容易，但我無法實現它的工作。
上下文始終顯式加載兩次。因爲這首先我得到了一個存儲庫異常（@Repository）我使用（已經被阻止）以及另一個來自spring的異常「由於已經存在根應用程序上下文，所以無法初始化上下文」。
我很困惑，因爲我已經閱讀過，這很正常，Spring創建了2個上下文，特別是使用MVC。但爲什麼例外呢？
我SpringApp類看起來像這樣
@EnableWebMvc
@ComponentScan
@EnableAutoConfiguration
public class LAuthServerApplication extends WebMvcConfigurerAdapter {
@Autowired
Environment env;
public static void main(String[] args) {
System.out.println("#################### Startup parameters ##############");
for (String s : args) {
System.out.println("Parameter: " + s);
}
System.out.println("######################################################");
SpringApplication.run(LAuthServerApplication.class, args);
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
@Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/pages/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
爲了使部署我加入這個類來我的項目：
@Configuration
public class AppServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}

你見過[春季啓動Devtools（HTTP：// docs.spring.io/spring-boot/docs/current/reference/html/using-boot-devtools.html）？允許您在IDE中調試應用程序時（不包裝在jar中時）即時調試和編輯js文件等文件。無需將其部署到Tomcat進行調試。 – Jesper
@她可以顯示你的pom文件嗎？我已經做了一個戰爭配置項目部署到tomcat。我可以與你分享 – cralfaro
