Java反射機制如何與安全管理器互動？

import java.lang.reflect.Method;
import java.lang.reflect.Field;
import java.security.Permission;

public class ReflectionSecurityExample {

    public static void main(String[] args) {
        try {
            // 获取安全管理器
            SecurityManager securityManager = System.getSecurityManager();

            // 获取类 Person 的成员信息
            Class<?> personClass = Person.class;
            Field nameField = personClass.getDeclaredField("name");
            Method getNameMethod = personClass.getMethod("getName");

            // 设置安全管理器的检查权限
            securityManager.checkPermission(new ReflectPermission("suppressAccessChecks"));

            // 访问私有字段和方法
            nameField.setAccessible(true);
            String name = (String) nameField.get(new Person("Alice"));
            String name2 = (String) getNameMethod.invoke(new Person("Bob"));

            System.out.println("Name: " + name);
            System.out.println("Name2: " + name2);
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

    private static class Person {
        private String name;

        public Person(String name) {
            this.name = name;
        }

        public String getName() {
            return name;
        }
    }
}
