Java 反射


#Java 反射、泛型与注解


示例1:

UserInfo 类

package org.example;

import java.io.Serializable;

public class UserInfo implements Serializable {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }


    @Override
    public String toString() {
        return "UserInfo{" +
                "name='" + name + '\'' +
                '}';
    }

    public static UserInfo of(String name) {
        UserInfo userInfo = new UserInfo();
        userInfo.setName(name);
        return userInfo;
    }

}

生成对象

方式1:

@Test
public void test_reflect() throws IllegalAccessException, InstantiationException {
    UserInfo userInfo = UserInfo.class.newInstance();
    userInfo.setName("x");
    System.out.println(userInfo);
}

执行结果:

UserInfo{name='x'}
