Question

我正在我的主机（Mac OS）中运行postgresql实例。我可以使用Spring Boot应用程序中的localhost属性通过JDBC访问此实例

现在我安装了一个来宾Ubuntu Virtual Box OS。我想从这个操作系统安装相同的实例。

所以我只是将同一个应用程序的数据源url从localhost更改为主机ip和端口。但是现在当我部署应用程序并尝试运行它时，我收到“连接被拒绝”错误。

从客户操作系统（10.0.2.2 5432）Telnet到主机操作系统工作正常。

我的pg_hba.conf文件中的内容

    # TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     md5
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local   replication     postgres                                md5
#host    replication     postgres        127.0.0.1/32            md5
#host    replication     postgres        ::1/128                 md5
host    all             all              0.0.0.0/0                       md5
host    all             all              ::/0                            md5

我的postgresql.conf中的连接和身份验证内容

    #------------------------------------------------------------------------------
# CONNECTIONS AND AUTHENTICATION
#------------------------------------------------------------------------------

# - Connection Settings -

listen_addresses = '*'              # what IP address(es) to listen on;
                    # comma-separated list of addresses;
                    # defaults to 'localhost'; use '*' for all
                    # (change requires restart)
port = 5432             # (change requires restart)
max_connections = 100           # (change requires restart)
#superuser_reserved_connections = 3 # (change requires restart)
#unix_socket_directories = '/tmp'   # comma-separated list of directories
                    # (change requires restart)
#unix_socket_group = ''         # (change requires restart)
#unix_socket_permissions = 0777     # begin with 0 to use octal notation
                    # (change requires restart)
#bonjour = off              # advertise server via Bonjour
                    # (change requires restart)
#bonjour_name = ''          # defaults to the computer name
                    # (change requires restart)

所以我已经将postgrsql实例配置为接受来自任何IP的连接。

我在防火墙后面。

可能我仍然缺少一些事情

最诚挚的问候， Saurav

我的Spring Boot和Cloud Foundry配置存在问题。这与Postgresql无关。
