Background description Recently, I wrote reflection-related code and wanted to get the name of the corresponding parameter, but found there was no particularly good way. jdk7 and before was not able to get parameter names through reflection. jdk8 is available, but there are many restrictions on specifying the-parameter startup parameter. I tri ...

Previously, we introduced ThreadLocal. Later, JDK made an upgrade version of InheritableThreadLocal for this purpose. Today, we will introduce it.<!-- more --> Why upgrade First of all, let's think about it. Why upgrade? This is about the function of ThreadLocal. We know that the original intention of ThreadLocal design is to have a copy ...

Blog Homepage Design of component-based routing architecture In the previous article, we explained the class loading and global Map recording to realize the interaction between component modules, and slowly derived the APT technology. So in the component architecture, we need to think about what kind of class files are generated through apt + j ...

When we read the JDK reflection package source code, we will encounter the isSynthetic() method. One of its implementations is Modifier.isSynthetic(getModifiers()), and the principle of other methods is the same. Modifier is a special class for defining modifiers, among which static final int synchronous = 0x00001000 is one of the modifiers.I t ...

Preface Previously, you showed how JDK implements exclusive and shared locks by implementing custom ReentrantLock and custom ReentrantReadWriteLock. So how do ReentrantLock and ReentrantReadWritreLock in the actual JDK source work?Can our existing custom code go any further? The answer is yes.Note that if you look at my two previous Lock friend ...
