Data acquisition method based on big data and big data system

The invention discloses a data collection method based on big data and a big data system.The method comprises the steps that a terminal runs a Java virtual machine corresponding to a Java application, a pre-configured burying point collector is loaded to the Java virtual machine, a burying point monitoring object is created in the loading process, burying point information is configured in the burying point collector, and the burying point information is stored in the burying point collector; the burying point information comprises a parameter name of the to-be-collected service parameter and a parameter path where the to-be-collected service parameter is located; monitoring whether a currently loaded path in the Java virtual machine is consistent with the parameter path or not based on the buried point monitoring object, intercepting the loaded path consistent with the parameter path, and taking the path as a target path; and based on a predetermined byte code, generating an operation library and a burying p
