通过字节码获取到的方法

1.

Method[] methods = Yuitest.class.getMethods();
for (Method method:methods){
    System.out.println( method.getName());
}
2.

Yuitest yuitest =new Yuitest();
Method[] methods = yuitest.getClass().getMethods();
for (Method method:methods){
   System.out.println( method.getName());
}
3.
方法：
public String goodName(String name) {

    System.out.println("哈哈哈。。。。。。。。。。。。");
    return "aaa";
}

加载获取：

Class<User> aClass = (Class<User>) Class.forName("com.example.demo.user.entity.User");
Method method = aClass.getMethod("goodName", String.class);
User user = aClass.newInstance();
Object aa = method.invoke(user, "aa");
System.out.println(aa);

静态获取：

public static String goodName(String... args) {
    System.out.println("哈哈哈。。。。。。。。。。。。");
    for (String str:args){
        System.out.println(str);
    }
    return "aaa";
}

获取：

Method goodName = User.class.getMethod("goodName", String[].class);
goodName.invoke(null,new Object[]{new String[]{"1","2"}});
