简单分析一下错误日志
java.version=11 表示我使用的jdk版本，最近操作系统升级到了jdk11，dbeaver我下载的是外置jre版本，所以这里打印的版本是11。
关键异常信息：java.lang.NoClassDefFoundError: javax/annotation/PreDestroy
PreDestroy 找不到是因为 Jdk9开始使用模块化，PreDestroy需要手动添加才可以支持。
我们来到dbeaver的根目录 打开 dbeaver.ini

-startup
plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.551.v20171108-1834
-showsplash
-vmargs
-XX:+IgnoreUnrecognizedVMOptions
--add-modules=ALL-SYSTEM
-Xms64m
-Xmx1024m

发现参数内 已经有了add-modules=ALL-SYSTEM 还是NoClassDefFoundError。不知道是不是dbeaver还不兼容jdk11 ，换其他的解决方案。

三·解决方案

打开dbeaver根目录下的readme.txt

  -f <sql-file1 [sql-file2..]>
    Open specified SQL file(s) in SQL editor.
    This command can be used to associate SQL files with DBeaver in shell.

  -nosplash
    Do not show splash screen

  -data <path>
    Store all projects/configuration in folder <path>. By default DBeaver
	stores all its data in user's home ".dbeaver4" folder.
	<path> can be an absolute or relative directory name.
	If you want to use DBeaver as redistributable program start it
	with arguments like "dbeaver -data workspace".

  -nl locale
    Use specified locale instead of default one.
    Example: -nl en (use English locale).

  -vm <java vm path>
    Use Java VM installed in <java vm path> folder instead of default
    location.

  -vmargs <jvm parameters>
    Allows to pass any number of additional parameters to JVM.
    Additional parameters may be used to customize environment or
    3-rd party jdbc drivers.

  -clean
    Clears all Eclipse caches. Use it if DBeaver fails to start after version upgrade.

我们使用-vm参数 指定jdk为jdk8的目录。
1·右键点击dbeaver.exe发送到桌面快捷方式

目标处填写-vm参数：D:\dbeaver\dbeaver.exe -vm “C:\Program Files\Java\jdk1.8.0_45\bin”
使dbeaver 启动的时候 使用指定的Jdk即可。
