idea+云函数实现Helloword

1. 新建maven项目

（1）按照格式创建

重点是 java 后面的包名和类名和方法名 ,要与云函数的执行方法对应，云函数后面会讲

（2）pom.xml 重点修改标为绿色（shade不支持高版本，例如3.2，会打包失败）

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<modelVersion>4.0.0</modelVersion>

<groupId>org.example</groupId>

<artifactId>hanshu</artifactId>

<version>1.0-SNAPSHOT</version>

<packaging>jar</packaging>

<name>hanshu Maven Webapp</name>

<!-- FIXME change it to the project's website -->

<url>http://www.example.com</url>

<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<maven.compiler.source>1.8</maven.compiler.source>

<maven.compiler.target>1.8</maven.compiler.target>

</properties>

 

<dependencies>

<dependency>

<groupId>junit</groupId>

<artifactId>junit</artifactId>

<version>4.11</version>

<scope>test</scope>

</dependency>

</dependencies>

<build>

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-shade-plugin</artifactId>

<version>3.1.1</version>

<configuration>

<createDependencyReducedPom>false</createDependencyReducedPom>

</configuration>

<executions>

<execution>

<phase>package</phase>

<goals>

<goal>shade</goal>

</goals>

</execution>

</executions>

</plugin>

</plugins>

</build>

</project>

 

（3）代码编写 （示例）

Hello类

package example;

public class Hello {

public String mainHandler(KeyValueClass kv) {

System.out.println("Hello world!天堂");

System.out.println(String.format("key1* = %s", kv.getKey1()));

System.out.println(String.format("key2* = %s", kv.getKey2()));

return String.format("我是大魔王，征服整个世界");

}

}

KeyValueClass类

package example;

public class KeyValueClass {

String key1;

String key2;

public String getKey1() {

return this.key1;

}

public void setKey1(String key1) {

this.key1 = key1;

}

public String getKey2() {

return this.key2;

}

public void setKey2(String key2) {

this.key2 = key2;

}

public KeyValueClass() {

}

}

 

（4）打包

点击idea左下角Terminal,直接输入 mvn package 静待打包完成

 



2. 构建云函数

1. 开通服务

直接搜索云函数，立即开通即可

2. 新建云函数

 

 

最后点击完成，及创建完成

 

3. 创建触发器，以api触发为例
