macos的“偏好設(shè)置”->java->更新1.8這樣更新的是本地的JRE，并不是JDK。
JDKYou can only update it manually.

Execute

ls -la /usr/bin/java

You will get the real storage location of the java command,

lrwxr-xr-x  1 root  wheel    74B  3 18  2016 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

Softly connect the installed version 1.8 directory to the directory/System/Library/Frameworks/JavaVM.framework/Versions/Current.

Remember, direct soft connection /usr/bin/java 命令到1.8版本的java，因為 /usr/bin/ 下還有java其他命令，如 javac， javapetc. is not allowed.

I keep making a mistake, just download jdk1.8.
