java 版本

openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

Answer 1

您好，我也遇到过与 OpenJDK9 相同的问题。

# java --version
openjdk 9.0.4
OpenJDK Runtime Environment (build 9.0.4+12-Debian-4)
OpenJDK 64-Bit Server VM (build 9.0.4+12-Debian-4, mixed mode)

# jruby -v
jruby 9.1.16.0 (2.3.3) 2018-02-21 8f3f95a OpenJDK 64-Bit Server VM 9.0.4+12-Debian-4 on 9.0.4+12-Debian-4 +jit [linux-x86_64]

和

activerecord-jdbc-adapter -v 1.3.24

我只是在 gem 级别给出了修复，然后它并没有阻止我继续进行下去。试试这个。转到以下路径中的 driver.rb:

activerecord-jdbc-adapter-1.3.24/lib/arjdbc/jdbc/driver.rb

然后在连接方式中编辑下面这行

properties = self.properties.clone 

将此更改为:

properties = self.properties.dup
