java应用程序按预期工作，但当我用docker上下文化应用程序时，它无法访问cassandra容器

我的申请有问题。在我和docker竞争应用程序之前，一切都很顺利。
我有一个docker容器，里面有cassandra示例 docker run -p 9042:9042 --name cassandra cassandra:latest *当我在intellij中运行我的应用程序或按cmd运行时 java -jar myjar.jar 很好用。当我尝试使用docker或docker compose启动应用程序时，出现了问题 docker run -p 8080:8080 --name api {image here} 或者 docker-compose up docker文件：

FROM openjdk:8
COPY . /target/myjar.jar 
EXPOSE 8080
ENTRYPOINT ["java","-jar","target/myjar.jar"]

Docker

version: '3'
services:
  app:
    build: ./app
      ports:
      - "8080:8080"
      depends-on:
      -cassandra
  cassandra:
    container_name 'cassandra'
    image: cassandra
    ports:
    - "9042:9042"

我试图解决的问题是：
更改应用程序端口
构建docker和docker以不同的方式组成文件。
应用程序属性

spring.data.cassandra.keyspace-name=message
spring.data.cassandra.schema-action=create_if_not_exists
spring.data.cassandra.contact-points=127.0.0.1
spring.data.cassandra.port=9042

尝试从图像（片段）运行容器时出错
