Docker：尝试将Spring Java Container应用连接到MS Sql Server容器：收到错误：连接失败

问题描述

    I am trying to connect to docker container of ms sql server 2017,through java spring boot application,In containerized environment its not getting connected and giving me error : 
    

com.microsoft.sqlserver.jdbc.sqlServerException：与主机localhost端口1433的TCP / IP连接失败。错误：“连接被拒绝。请验证连接属性。请确保主机上正在运行sql Server实例并在端口上接受TCP / IP连接。请确保与端口的TCP连接没有被防火墙阻止。

    However If I run Spring app locally it gets connected to Ms sql server container.
    
My spring boot application.properties:

spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.sqlServerDriver
spring.datasource.url=jdbc:sqlserver://localhost;databaseName=master
spring.datasource.username=sa
spring.datasource.password=Ms@12345
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql = true
    

# The sql dialect makes Hibernate generate better sql for the chosen database
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.sqlServer2012Dialect


spring.jpa.hibernate.ddl-auto = update
spring.main.allow-bean-deFinition-overriding=true

Configured docker-compose.yml as below

    version: '3'
    services:
    
      myteamapp-mssqlserver:
        image: "mcr.microsoft.com/mssql/server:2017-latest"
