我在这里看了很多(太多)类似的问题，并一遍又一遍地尝试解决这个问题，但我无法完全解决。
我有一个java代码，它连接到RHEL 8.2盒子上的PostGreSQL服务器来查询和返回一个值。 当我在 Windows 10 笔记本电脑上运行它时;它可以毫无问题地工作。 但是，当我在 Linux 盒子上本地运行它时，它失败了，并带有可怕的 org.postgresql.util.PSQLException：致命：主机没有 pg_hba.conf 条目。
java代码由一个名为Talend的ETL软件编写;代码由RunDeck在Linux上运行。
更令人困惑的是，我可以以 postgres 用户的身份登录 Linux 并使用 psql 界面连接到具有我在 Java 中使用的相同主机、端口、数据库和用户的数据库，而不会出错-
psql -h [server ip] -p 5432 -d my_special_db -U my_db_user
我已经检查了服务器设置，pg_hba.conf文件，用户权限，日志文件，并尝试更改上述所有内容以获得某种回报; 都无济于事。
我已添加到 pg_hba.conf：
host my_special_db my_db_user [server ip]/32 md5
host my_special_db my_db_user [server ip with .0 as the last quatraine]/24 md5
host my_special_db root ::1/128 trust
host all all [server ip]/32 trust
我尝试了多个连接修饰符，例如：
sslfactory=org.postgresql.ssl.NonValidatingFactory&sslmode=prefer
or
sslmode=prefer
or
sslmode=Require
or
no modifier at all
请指教。

即使在以下更新之后，我也收到了此错误-
更新到 postgresql.conf 文件：
edit 1
ssl = off
edit 2
ssl = on
edit 3
#ssl = off
将 postgresql.conf 文件中的日志级别更新为
log_line_prefix = '[%p] [%c] [%m] [%v] [%e] [%i] [%d] [%u] [%a] [%r] [%l] [%x]: '
...
log_statement = 'all'
更新了 pg_hba.conf 文件以开头：
# Allow any user on the local system to connect to any database with
# any database user name using Unix-domain sockets (the default for local
# connections).
#
# TYPE DATABASE USER ADDRESS METHOD
local all all trust
# The same using local loopback TCP/IP connections.
#
# TYPE DATABASE USER ADDRESS METHOD
host all all 127.0.0.1/32 trust
# The same as the previous line, but using a separate netmask column
#
# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD
host all all 127.0.0.1 255.255.255.255 trust
# The same over IPv6.
#
# TYPE DATABASE USER ADDRESS METHOD
host all all ::1/128 trust
# The same using a host name (would typically cover both IPv4 and IPv6).
#
# TYPE DATABASE USER ADDRESS METHOD
host all all localhost trust
hostssl all all 0.0.0.0/0 md5
还更新了连接参数-
sslfactory=org.postgresql.ssl.NonValidatingFactory
根据postgres的说法，这应该可以停止任何和所有SSL问题，并让连接通过-
https://jdbc.postgresql.org/documentation/head/ssl-client.html
"非验证连接是通过驱动程序提供的自定义SSLSocketFactory类建立的。设置连接 URL 参数 sslfactory=org.postgresql.ssl.NonValidatingFactory 将关闭所有 SSL 验证。

我无法将错误日志粘贴到此处，因为将其详细化后很长 - 所以我做了一个要点
最后更新：
我删除了要点，因为这里的窥视帮助我找到了错误：
好的，所以问题是 3 件事; 事情 1，我们有一个"属性"文件，我认为它已在此数据库中设置为此服务器; 它不是//事情 2，默认日志记录设置为"警告"并且没有足够的信息，因此在将其放入调试级别 5(最多数据)和"所有"事件后;我终于看到了一条错误消息，让我意识到它指向了错误的 db//事物 3，在我添加然后删除 IP 地址的 pg_hba.conf 文件的多次(太多)迭代中。 所以现在它正在工作，哈哈 有时你离铁轨太近了，看不到火车，哈哈
