应用程序运行后，Spring Boot 应用程序关闭

如何解决应用程序运行后，Spring Boot 应用程序关闭

我尝试使用 spring 初始值设定项创建 Spring 启动应用程序。我刚刚使用依赖项创建了新应用

import React,{ useState } from "react";
import {
  GoogleMap,InfoWindow,Marker,polyline
} from "@react-google-maps/api";

import scheduledOrders from "./data.json";

function Map() {
  const [activeMarker,setActiveMarker] = useState(null);

  let markers =
    scheduledOrders !== undefined &&
    scheduledOrders &&
    scheduledOrders.map((item,index) => ({
      id: index + 1,name: item.customerName + " - " + item.customerAddress,position: {
        lat: Number(item && item.order_lat,10),lng: Number(item && item.order_lng,10)
      }
    }));

  console.log("@@@markser",scheduledOrders);

  const handleActiveMarker = marker => {
    if (marker === activeMarker) {
      return;
    }
    setActiveMarker(marker);
  };

  const handleOnLoad = map => {
    const bounds = new window.google.maps.LatLngBounds();
    markers && markers.forEach(({ position }) => bounds.extend(position));
    map.fitBounds(bounds);
  };

  return (
    <GoogleMap
      onLoad={handleOnLoad}
      onClick={() => setActiveMarker(null)}
      mapContainerStyle={{ width: "100%",height: "88vh" }}
    >
      <polyline
        path={
          scheduledOrders !== undefined &&
          scheduledOrders &&
          scheduledOrders[0] &&
          scheduledOrders.map(item => ({
            lat: Number(item && item.order_lat,10)
          }))
        }
        options={{
          strokeColor: "#07966B",strokeOpacity: 1,strokeWeight: 2,icons: [
            {
              icon: "hello",offset: "0",repeat: "10px"
            }
          ]
        }}
      />

      {/* The following Marker object will check if the index is the start or end */}
      {markers &&
        markers.map(({ id,name,position },i,arr) => {
          if (i == 0 || i == arr.length)
            return (
              <Marker
                key="start"
                position={position}
                onClick={() => handleActiveMarker("start")}
                label={{ text: `START`,color: "black" }}
                icon="http://maps.google.com/mapfiles/kml/shapes/arrow.png"
              >
                {activeMarker === "start" ? (
                  <InfoWindow onCloseClick={() => setActiveMarker(null)}>
                    <div>This is the start</div>
                  </InfoWindow>
                ) : null}
              </Marker>
            );
          return (
            <Marker
              key={id}
              position={position}
              onClick={() => handleActiveMarker(id)}
              label={{ text: `${id - 1}`,color: "white" }}
            >
              {activeMarker === id ? (
                <InfoWindow onCloseClick={() => setActiveMarker(null)}>
                  <div>{name}</div>
                </InfoWindow>
              ) : null}
            </Marker>
          );
        })}
    </GoogleMap>
  );
}

export default Map;

但是当我尝试启动应用程序时它就会关闭。我已经创建了控制器并遵循了所有解决方案，例如：更改端口或从 .m2 文件夹中删除 tomcat 但没有任何效果。 这是我的日志

keep='last'

如果有人知道出了什么问题。 我使用的是 spring boot 2.4.5 版本。

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <scope>runtime</scope>
    </dependency>
    <dependency>

解决方法

似乎tomcat 嵌入的jar 没有包含在dependencies/jar 中。因为已经定义了“spring-boot-starter-web”依赖项，所以它应该是传递性的。但不知何故，它被排除在外。

尝试执行“mvn dependency:tree”并检查tomcat依赖是否存在并在“compile”范围内
