Java虚拟机是如何加载Java类的？这个问题也就是面试常问到的Java类加载机制。在年初面试百战之后，菜鸟喜鹊也是能把这流程倒背如流啊！但是，也只是字面上的背诵，根本就是像上学时背书考试一样。

tonight ！我们把它映射到实战里，看看如何用代码说明这个流程。

ready! go! ----------------在这之前还是搞点理论吧，不然又要先去百度加载机制流程了。

一、类加载机制（理论部分）

类加载机制有三大过程：加载、链接、初始化。其中链接又细分为验证、准备及解析。

Java语言的类型分为两大类：基本类型和引用类型。Java的基本类型是由Java虚拟机预先定义好的。而引用类型又分为：数组类、类、接口、泛型参数。在JVM中，只存在数组类、类、接口三类，而数组类是直接由Java虚拟机直接生成的，其他两类则有字节流而来。

字节流又是怎么来呢？最常见的还是从字节码文件而来（还可以从网络等而来）。所以，我就以字节码文件分析一下加载机制。

1.加载

加载是指查找字节流，并据此创建类的过程。对于数组类来说，它们是可以由Java虚拟机直接生成。而其他两类，却需要借助类加载器，Java虚拟机才能完成查找字节流的工作。

类加载器与类的关系就像是UI与效果图一样，需要将业务需求翻译成效果图。美丽的UI就是类加载器，效果图就是类。

类加载器有一个关系：双亲委派。类加载器分为三种，启动类加载器、扩展类加载器、应用类加载器。

其中，

启动类加载器是负责加载最为基础、最为重要的类，比如存放在JRE的lib目录下jar包中的类

扩展类加载器的父类加载器是启动类加载器，它负责加载相对次要、但又通用的类，比如存放在JRE的lib/ext目录下的jar包中的类（以及由系统变量java.ext.dir指定的类）

应用类加载器的父类加载器是扩展类加载器，它负责加载应用程序路径下的类，通常情况下是我们写的java代码。（这里的应用路径便是 -cp/-classpath、环境变量CLASSPATH所指定的路径）。

这三者的关系可以这样描述：

每当类加载器接收到加载请求时，它会先将请求转发给父类加载器，在父类加载器中没有找到需要的类的情况下，该加载器才会尝试去加载。

比如，应用加载器接收到加载请求，
会先去找父类加载器（扩展类加载器）里有没有需要的类，但该扩展类加载器顶头还有父类加载器（启动类加载器），
所以还要去启动类加载器中查找是否存在需要的类，如果不存在，那扩展类加载器就会自己加载需要的类，
然后把引用传递给应用加载器。

类加载器还有一个功能，就是提供命名空间的作用。

在Java虚拟机中，类的唯一性是由类加载器实例以及类的全名一同确定的。即便是同一串字节流，经过不同的类加载器加载，也会得到两个不同的类。（这里可以读者自己实现一下，用两个扩展类加载器加载同一个类，然后打印一下类信息就可以验证了）

2.链接

链接：将创建成的类合并至Java虚拟机中，使之能够执行的过程。（这里是下面代码要验证一个步骤）

链接分为验证、准备、解析。

验证的目的是为了让被加载的类能够满足Java虚拟机的约束。（关于约束条件，今天暂时不讲。）

准备的目的是为了被加载类的静态字段分配内存。（仅仅是分配内存，并没有在内存中写东西）除此之外，有些Java虚拟机还会用来实现虚方法的动态绑定的方法表。

下一步就是我们链接的重要步骤--解析

对于一个方法的调用，编译器会解析一个符号，这个符号能够无歧义地定位到具体的目标上。这个符号包含目标方法所在类的名字、目标方法的名字、接收的参数类型以及返回值类型的符号引用。

如果符号引用指向一个未被加载的类、字段、方法，那么这个解析将触发加载功能。

3.初始化

初始化：为标记为常量值的字段赋值，以及执行方法的过程。

只有初始化完成之后，类才正式成为可执行的状态。

那初始化这个步骤是什么时候执行呢？

JVM规范枚举了下述多种触发初始化的情况：

理论部分讲解完了。（小声bb......copy over from https://time.geekbang.org/column/article/11523）

二、类加载机制（Linux查看字节码）

在这，主要是因为网上都是一大串的理论描述，看得也是半信半疑。还不如拿出代码来，让自己也心服口服了。

talk is cheap,show the code!

1.classloader

输出如下：

结果很惊人，为什么父类加载器的父类加载器（我自己取名为爷爷类加载器。。），照理论来说，应该打印的是bootstrapClassLoader。其实是它隐身了。贴一下代码里的一段注释：

* Returns the parent class loader for delegation. Some implementations may
* use null to represent the bootstrap class loader. This method
* will return null in such implementations if this class loader's
* parent is the bootstrap class loader.

翻译黄色的句子就是：如果父类加载器是启动类加载器，则将返回null

但还是没解决怎么找bootstrapClassLoader啊。

它实际上不是 java.lang.ClassLoader的子类，而是由JVM自身实现的，我们可以通过这个方法得到实现的类路径。

URL[] urls=sun.misc.Launcher.getBootstrapClassPath().getURLs();

2.链接

3.初始化

1.编译的单例类：Singleton.java

public class Singleton{
private Singleton(){}
private static class LazyHolder{
static final Singleton INSTANCE = new Singleton();
static{
System.out.println("LazyHolder.");
}
}
public static Object getInstance(boolean flag){
if(flag) return new LazyHolder[2];
return LazyHolder.INSTANCE;
}
public static void main(String... args){
System.out.println("---");
getInstance(true);
System.out.println("---");
getInstance(false);
}
}

2.编译并运行

[root@localhost tmp3]# javac Singleton.java
[root@localhost tmp3]# java Singleton
---
---
LazyHolder.

3.查看字节码文件（用的新指令：java -verbose:class Singleton）

结合2,3的输出，我想，我该讲点啥。

在两段“-----”中，如果没有打印加载信息，我们就以为是连续输出了。但是并没有。根据加载信息来看，中间还会加载Singleton$LazyHolder这个内部类，而这一步，对应的就是getInstance(true)；。说明了啥？说明了前面理论部分的链接的最后一句话：

如果符号引用指向一个未被加载的类、字段、方法，那么这个解析将触发加载功能。

这里注意的是，仅仅调用了加载功能而已，这里只完成了创建类而已，并没有让它继续进行链接和初始化功能。所以在这里，也就不会出现打印“LazyHolder.”的字样。

当使用到了getInstance(true)的时候，由于需要使用到“LazyHolder.INSTANCE;”这个静态常量，而它又与new 构造器方法相连通，此时就满足了理论中初始化的解释：

2.当遇到用以新建目标类实例的new指令时，初始化new指令的目标类
3.当遇到访问静态字段的指令时，初始化该静态字段所在的类

在这，大家应该也有疑问：getInstance(false)的时候也有new啊。但是，false时候的new，只是new数组，数组里装的只是加载时候生成的类引用。

大家还可以看下面class字节码就知道，注释那里就标记着很清楚是类引用而已。

Singleton.class

public static java.lang.Object getInstance(boolean);
descriptor: (Z)Ljava/lang/Object;
flags: ACC_PUBLIC, ACC_STATIC
Code:
stack=1, locals=1, args_size=1
0: iload_0
1: ifeq 9
4: iconst_2
5: anewarray #3 // class Singleton$LazyHolder
8: areturn
9: getstatic #4 // Field Singleton$LazyHolder.INSTANCE:LSingleton;
12: areturn
LineNumberTable:
line 11: 0
line 12: 9
StackMapTable: number_of_entries = 1
frame_type = 9 /* same */
public static void main(java.lang.String...);
descriptor: ([Ljava/lang/String;)V
flags: ACC_PUBLIC, ACC_STATIC, ACC_VARARGS
Code:
stack=2, locals=1, args_size=1
0: getstatic #5 // Field java/lang/System.out:Ljava/io/PrintStream;
3: ldc #6 // String ---
5: invokevirtual #7 // Method java/io/PrintStream.println:(Ljava/lang/String;)V
8: iconst_1
9: invokestatic #8 // Method getInstance:(Z)Ljava/lang/Object;
12: pop
13: getstatic #5 // Field java/lang/System.out:Ljava/io/PrintStream;
16: ldc #6 // String ---
18: invokevirtual #7 // Method java/io/PrintStream.println:(Ljava/lang/String;)V
21: iconst_0
22: invokestatic #8 // Method getInstance:(Z)Ljava/lang/Object;
25: pop
26: return
LineNumberTable:
line 15: 0
line 16: 8
line 17: 13
line 18: 21
line 19: 26
Singleton(Singleton$1);
descriptor: (LSingleton$1;)V
flags: ACC_SYNTHETIC
Code:
stack=1, locals=2, args_size=2
0: aload_0
1: invokespecial #1 // Method "":()V
4: return
LineNumberTable:
line 1: 0
}

可以看到，在getInstance中，那么#3 和#4 对应的是啥

现在，

看了例子之后，大家应该也对加载机制有了一点点了解了吧。
