试了各种方法都没解决，最终重新安装了Java，下载地址，
下载后查看Java安装目录： /usr/libexec/java_home -V
打印如下：

wf@localhost ~ % /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    1.8.321.07 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_321 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_321.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

把 /Library/Java/JavaVirtualMachines/jdk1.8.0_321.jdk/Contents/Home/lib 目录下的tools.jar 拷贝到 /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib

重新运行就可以了。
