Java class loading mechanism class loader Class loader execution flow Types of class loaders Relationships between loaders Main method of ClassLoader The difference between Class.forName() and ClassLoader.loadClass() Parental delegation model Parental delegation class loading process Advantages and Disadvantages Simple example of hot deployment Class loader Execution process of class loader Types of class loaders AppClassLoader […]
JVM performance optimization – class loader, manually implement hot loading of classes
1. Hierarchy of class loading mechanism Each written class file with the “.java” extension stores the program logic that needs to be executed. These “.java” files are compiled into files with the extension “.class” by the Java compiler. The “.class” files are saved in According to the virtual machine instructions after the Java code is […]
SpringBoot SerializationUtils cloning (deserialization) class loader inconsistency problem (ClassCastException)
Problem analysis When using the org.apache.commons.lang.SerializationUtils.clone method in SpringBoot, it was found that a type inconsistency error occurred when the cloned class was forced to the corresponding class. After inspection, it was found that two seemingly identical Class loaders for classes are inconsistent Scene Error message java.lang.ClassCastException: com.tianqiauto.tis.pc.dingdanyupai.po.PrePoint cannot be cast to com.tianqiauto.tis.pc.dingdanyupai.po.PrePoint Detection information […]
Pytorch specifies data loader to use subprocess
torch.utils.data.DataLoader(train_dataset, batch_size=batch_size, shuffle=True,num_workers=4, pin_memory=True) The num_workers parameter is a parameter of the DataLoader class that specifies the number of child processes used by the data loader. By increasing the number of num_workers, data can be read and preprocessed in parallel, thereby increasing the speed of data loading. Typically, increasing the number of num_workers can improve […]

Use a class loader or class object to read the file (the reference path is the folder after compilation, out or target folder)
The following content is summarized by me using Maven project, so it will be different from the project directory of ordinary projects. Relative path: The root directory of the project to start the search. (But when we are actually developing, the more files we read are not placed directly in the folder in our project, […]
