1. Download and install Quartz

⊙docs: Documents related to quartz, including APIs.

⊙examples: The sample program that holds the quartz.

⊙javadoc: Store Quartz API documentation.

⊙lib: The jar package that holds quartz, and the third-party class library on which quartz compiles or runs.

⊙SRC: The source file that holds the quartz.

⊙ other Quartz related documents.

Tip: Actually quartz still uses slf4j as the logging tool, so you also need to copy the SLF4J-related jar package from the lib/subdirectory into the project's class load path.

Basic Properties for 2.Quartz operation

Quartz allows you to provide a configuration file named Quartz.properties that allows you to modify the environment in which the framework runs. The quartz.properties file in Quartz-x.x.x.jar is used by default (under the Org\quartz path of the compressed file). If you need to change the default Quartz property, the program can create a quartz.properties file on its own and place it under the class load path of the system, and ClassLoader will automatically load and enable the various properties.
