【问题描述】:
我有一个在我的本地机器上运行的 Spring Boot 休息服务项目。当我将应用程序作为“Spring Boot App”运行时
我可以通过去访问休息服务
http://127.0.0.1:8080/persons/all
它会按预期返回 JSON。
我将 pom.xml 打包更改为 war,然后我通过转到 Run as -> Maven build in Spring tools suit 创建了一个战争。它创建一个战争文件。当我在http://myserverip:8080/manager/ 上上传战争文件时,我没有收到任何错误,它显示在应用程序下
上传后war文件名为“myapp-0.0.1-SNAPSHOT.war”,我尝试访问
http://myserverip:8080/myapp-0.0.1-SNAPSHOT/persons/all
但我收到 404 错误
我在这里做错了什么?
我的 pom.xml

【问题讨论】:
-
您可以在 pom.xml 中将您的 buid 名称更改为 myapp。在服务器启动时检查
/persons/all是否已注册。如果没有,它将显示 404 错误,因为您的控制器未正确注册。 -
@Lucky 但该应用程序在我的本地计算机上运行良好。是否有可能在 Spring boot 本地注册,但在 Tomcat 上使用 war 文件部署时不注册?
-
是的,请检查您的 Tomcat 服务器日志。 Spring Boot 使用嵌入式 tomcat。您正在部署到一个单独的 tomcat 实例中。两者都不一样。
-
@Lucky 启动 tomcat 后我确实看到 myapp 正在部署,但没有关于 /persons/all pastebin.com/9iyPxuBs
-
我希望您的组件、配置、服务在
company包下。如果这个包里没有那些。另外,不要使用三个@Configuration、@EnableAutoConfiguration和@ComponentScan注释,而是使用这个@SpringBootApplication注释。还将spring-webmvc依赖项添加到您的webapp。这会将应用程序标记为 Web 应用程序并激活关键行为,例如设置DispatcherServlet。(即类似于添加@EnableWebMvc)
