01_JVM学习笔记_类加载机制详解一

概述

把描述类的数据从Class文件加载到内存，并对数据进行校验、转换解析和初始化，最终形成可以被虚拟机直接使用的Java类型，这就是虚拟机的类加载机制。
在java代码中，类型的加载、连接与初始化过程都是在程序运行期间完成的。
提供了更大的灵活性，增加了更多的可能性。

类的加载、连接与初始化

加载：查找并加载类的二进制数据

类的加载指的是将类的.class文件中的二进制数据读入到内存中，将其放在运行时数据区的方法区内，然后在内存中创建一个java.lang.Class对象（规范并未说明Class对象位于哪里，HotSpot虚拟机将其放在了方法区中）用来封装类在方法区内的数据。

加载.class文件的方式

①从本地系统中直接加载

②通过网络下载.class文件

③从zip，jar等归档文件中加载.class文件

④从专有数据库中提取.class文件

⑤将Java源文件动态编译为.class文件

连接

① 验证：确保被加载的类的正确性

②准备：为类的静态变量分配内存，并将其初始化为默认值

③解析：把类中的符号引用转换为直接引用
初始化:为类的静态变量赋予正确的初始值

从类被加载到虚拟机内存中开始，到卸载出内存为止，它的整个生命周期分为5个阶段，加载(Loading)、连接（Linkging）、初始化(Initialization)、使用(Using)、卸御(Unloading)

JAVA虚拟机与程序的生命周期

在如下几种情况下，Java虚拟机将结束生命周期

①执行了System.exit()方法

②程序正常执行结束

③程序在执行过程中遇到了异常或者错误而异常终止

④由于操作系统出现错误而导致Jaava虚拟机进程终止

Java程序对类的使用方式

①主动使用（七种）

创建类的实例
访问某个类或接口的静态变量，或者对该静态变量赋值
调用类的静态方法
反射（如：Class.forName("com.test.Test"))
初始化一个类的子类
Java虚拟机启动时被标明为启动类的类（Java Test）
JDK1.7开始提供了动态语言支持：java.lang.invoke.MethodHandle实例的解析结果REF_getStatic，REF_putStatic,REF_invokeStatic句柄对应的类没有初始化，则初始化。

②被动使用

除了以上七种情况，其他使用Java类的方式都被看作是对类的被动使用，都不会导致类的初始化

所有的Java虚拟机实现必须在每个类或接口被Java"首次主动使用时才初始化他们

示例

示例1

class MyParent1 {

    public static String str = "hello world";

    static {
        System.out.println("MyParent1 static block");
    }
}

class MyChild1 extends MyParent1 {

    public static String str2 = "welcome";

    static {
        System.out.println("MyChild1 static block");
    }
}

该main方法执行后，会输入什么结果呢？

public class MyTest1 {

    public static void main(String[] args) {
        System.out.println(MyChild1.str);
    }
}

输出：

MyParent1 static block
hello world

为什么MyChild1的静态代码块没实例化呢？

对于静态字段来说，只有直接定义了该字段的类才会被初始化.

该main方法执行后，又会输入什么结果呢？

public class MyTest1 {

    public static void main(String[] args) {
        System.out.println(MyChild1.str2);
    }
}

输出：

MyParent1 static block
MyChild1 static block
welcome

这次为什么子类与父类的静态代码块都实例化了呢？

当一个类在初始化时，要求其父类全部都已经初始化完毕了。

JVM参数

-XX:+TraceClassLoading,用于追踪类的加载信息并打印出来

-XX:+<option>,表示开启option选项

-XX:-<option>,表示关闭option选项

-XX:<option>=<value>,表示将option选项的值设置为value

通过-XX:+TraceClassLoading参数我们来看下调用MyChild1.str类的加载情况

示例2

class MyParent2 {

    public static String str = "hello world";

    static {
        System.out.println("MyParent2 static block");
    }
}

执行该main方法会输出什么结果

public class MyTest2 {

    public static void main(String[] args) {
        System.out.println(MyParent2.str);
    }
}

输出

MyParent2 static block
hello world

上述代码是对于MyTest2的主动使用，主动使用会导致它初始化，初始化就会使的静态代码块的执行。

对上述代码str属性增加fina修饰，修改后的代码如下：

class MyParent2 {

    public static final String str = "hello world";

    static {
        System.out.println("MyParent2 static block");
    }
}

再执行main方法会输出什么呢？

public class MyTest2 {

    public static void main(String[] args) {
        System.out.println(MyParent2.str);
    }
}

输出：

hello world

为什么静态代码块没执行呢？

常量在编译阶段会存入到调用这个常量的方法所在类的常量池中，本质上，调用类并没有直接引用到定义常量的类，因此并不会触发定义常量的类的初始化。

注意：这里指的是将常量存放到MyTest2的常量池中，之后MyTest2与MyParent2就没任何关系了,甚至，我们可以将MyParent2的class文件删除。

反编译该程序javap -c com.leofight.jvm.classloader.MyTest2

public class com.leofight.jvm.classloader.MyTest2 {
  public com.leofight.jvm.classloader.MyTest2();
    Code:
       0: aload_0
       1: invokespecial #1                  // Method java/lang/Object."<init>":()V
       4: return

  public static void main(java.lang.String[]);
    Code:
       0: getstatic     #2                  // Field java/lang/System.out:Ljava/io/PrintStream;
       3: ldc           #4                  // String hello world
       5: invokevirtual #5                  // Method java/io/PrintStream.println:(Ljava/lang/String;)V
       8: return
}

main方法中的ldc的注释是String hello world，也就是说这段代码已经是hello world了。

ldc表示将int、float或者是String类型的常量值从常量池中推送至栈顶。

对上述程序做修改，修改如下：

class MyParent2 {

    public static final String str = "hello world";

    public static final short s = 7;

    static {
        System.out.println("MyParent2 static block");
    }
}

public class MyTest2 {

    public static void main(String[] args) {
        System.out.println(MyParent2.s);
    }
}

输出：

反编译结果：


public class com.leofight.jvm.classloader.MyTest2 {
  public com.leofight.jvm.classloader.MyTest2();
    Code:
       0: aload_0
       1: invokespecial #1                  // Method java/lang/Object."<init>":()V
       4: return

  public static void main(java.lang.String[]);
    Code:
       0: getstatic     #2                  // Field java/lang/System.out:Ljava/io/PrintStream;
       3: bipush        7
       5: invokevirtual #4                  // Method java/io/PrintStream.println:(I)V
       8: return
}

bipush表示将单字节（-128 ~ 127）的常量值推送至栈顶。

修改‘public static final short s = 127;’，反编译结果：

public class com.leofight.jvm.classloader.MyTest2 {
  public com.leofight.jvm.classloader.MyTest2();
    Code:
       0: aload_0
       1: invokespecial #1                  // Method java/lang/Object."<init>":()V
       4: return

  public static void main(java.lang.String[]);
    Code:
       0: getstatic     #2                  // Field java/lang/System.out:Ljava/io/PrintStream;
       3: bipush        127
       5: invokevirtual #4                  // Method java/io/PrintStream.println:(I)V
       8: return
}

与上一个程序一样，助记符没变。

继续修改，如下：

class MyParent2 {

    public static final String str = "hello world";


    public static final short s = 127;


    public static final int i = 128;

    static {
        System.out.println("MyParent2 static block");
    }
}


public class MyTest2 {

    public static void main(String[] args) {
        System.out.println(MyParent2.i);
    }
}

反编译结果：

ublic class com.leofight.jvm.classloader.MyTest2 {
  public com.leofight.jvm.classloader.MyTest2();
    Code:
       0: aload_0
       1: invokespecial #1                  // Method java/lang/Object."<init>":()V
       4: return

  public static void main(java.lang.String[]);
    Code:
       0: getstatic     #2                  // Field java/lang/System.out:Ljava/io/PrintStream;
       3: sipush        128
       6: invokevirtual #4                  // Method java/io/PrintStream.println:(I)V
       9: return
}

sipush表示将一个短整型常量值（-32768 ~ 32767）推送至栈顶。

继续修改，代码如下：


class MyParent2 {

    public static final String str = "hello world";


    public static final short s = 127;


    public static final int i = 128;

    public static final int m = 1;


    static {
        System.out.println("MyParent2 static block");
    }
}

public class MyTest2 {

    public static void main(String[] args) {
        System.out.println(MyParent2.m);
    }
}

反编译结果：

public class com.leofight.jvm.classloader.MyTest2 {
  public com.leofight.jvm.classloader.MyTest2();
    Code:
       0: aload_0
       1: invokespecial #1                  // Method java/lang/Object."<init>":()V
       4: return

  public static void main(java.lang.String[]);
    Code:
       0: getstatic     #2                  // Field java/lang/System.out:Ljava/io/PrintStream;
       3: iconst_1
       4: invokevirtual #4                  // Method java/io/PrintStream.println:(I)V
       7: return
}

iconst_1表示将int类型1推送至栈顶(iconst_1 ~ iconst_5)

助记符总结

ldc表示将int、float或者是String类型的常量值从常量池中推送至栈顶。

bipush表示将单字节（-128 ~ 127）的常量值推送至栈顶。

sipush表示将一个短整型常量值（-32768 ~ 32767）推送至栈顶。

iconst_1表示将int类型1推送至栈顶(iconst_m1,iconst_0 ~ iconst_5)
