将 SpringBoot 应用程序部署到远程 Tomcat 服务器

Question

我有一个 Tomcat 和一个 Postgres 服务器，它们运行在我 LAN 中的远程服务器上。 Tomcat/Postgres 在此 IP 地址下运行：192.168.0.143

当我通过 Intellij 运行/测试我的应用程序并指向

http://localhost:8080/incomeoutgo

效果很好。

现在，当我部署到我的 Tomcat 服务器并使用以下设置时：

application.properties

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto=none
spring.jpa.hibernate.show-sql=true
spring.datasource.url=jdbc:postgresql://192.168.0.143:5432/incomeoutgo
spring.datasource.username=postgres
spring.datasource.password=xxx

收入和费用申请

@SpringBootApplication
public class IncomesAndExpensesApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application)
    {
        return application.sources(IncomesAndExpensesApplication.class);
    }
    public static void main(String[] args) {
        SpringApplication.run(IncomesAndExpensesApplication.class, args);
    }
}

我总是收到错误消息，说：

白标错误页面

为了访问网站，我通过 Tomcat manager-gui 来访问，这指向这里：

http://192.168.0.143:8080/IncomeAndExpenses/

我通过这样写来扩展 URL：

http://192.168.0.143:8080/IncomeAndExpenses/incomeoutgo <-- this comes from the Controller

但是，它仍然无法正常工作，我总是收到 status=500 错误。
