geoserver采用的对应jre版本

一句话：推荐采用GRE8.

GeoServer’s speed depends a lot on the chosen Java Runtime Environment (JRE). The latest versions of GeoServer are tested with both Oracle JRE and OpenJDK. Implementations other than those tested may work correctly, but are generally not recommended.

Tested:

Java 8 - GeoServer 2.9.x and above (OpenJDK and Oracle JRE tested)

Java 7 - GeoServer 2.6.x to GeoServer 2.8.x (OpenJDK and Oracle JRE tested)

Java 6 - GeoServer 2.3.x to GeoServer 2.5.x (Oracle JRE tested)

Java 5 - GeoServer 2.2.x and earlier (Sun JRE tested)

Unsupported:

Java 9 - Incompatibility with Service Provider Interface Plugin System has been noted

For best performance we recommend the use Oracle JRE 8 (also known as JRE 1.8).
