java对象转字节数组，获取泛型类

对象转字节数组，字节数组在恢复成对象

Test.java

class Test {
    public static void main(String args[]) throws IOException, ClassNotFoundException {
        TestObject to=new TestObject();
        to.setAge();
        to.setName("lisi");
        ByteArrayOutputStream byt=new ByteArrayOutputStream();
        ObjectOutputStream oos=new ObjectOutputStream(byt);
        oos.writeObject(to);
 
        byte oArr[]=byt.toByteArray();
        ByteArrayInputStream bis=new ByteArrayInputStream(oArr);
        ObjectInputStream obs=new ObjectInputStream(bis);
        TestObject to1= (TestObject) obs.readObject();
 
        System.out.println(to1.getName());
        System.out.println(to1.getAge());
    }
}

TestObject.java

public class TestObject implements Serializable {
    private String name;
    private int age;
 
    public String getName() {
        return name;
    }
 
    public void setName(String name) {
        this.name = name;
    }
 
    public int getAge() {
        return age;
    }
 
    public void setAge(int age) {
        this.age = age;
    }
}

获取泛型类

public class Test<T> {
    private Type entityClass;
    public Son() {
        getSuperclassTypeParameter();
    }
 
    public    void getSuperclassTypeParameter() {
        Type superclass = getClass().getGenericSuperclass();
        if (superclass instanceof Class) {
            throw new RuntimeException("Missing type parameter.");
        } else {
            ParameterizedType parameterized = (ParameterizedType)superclass;
            System.out.println(parameterized);
        }
    }
    public static void main(String args[]) {
        Son<AuthenticatorUser> s=  new Son<AuthenticatorUser>(){};
 
    }
}
