6 ,java 代码 :

  1. 接收消息用的 pojo 类 :
package com.lifecycle;

public class Person {
    private String id;
    private String name;

    public Person(){}

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

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

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

7 ,编写主代码 :

package com.lifecycle;

import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;

public class Hello implements RequestHandler<Person, String>{
    public String handleRequest(Person p, Context context) {
        System.out.println(123);
        return "456";
    }
}

8 ,压缩 :

maven : package

9 ,上传 :

04 ,lambda 介绍,helloWorld :

11 ,测试 :

12 ,成功的标志 :

看到我们输出的字符串
