如何从AWS Lambda Java中的类路径加载属性文件 [英] How to load property file from classpath in AWS lambda java

问题描述

我编写了AWS lambda函数，因为我想从属性文件中读取数据库连接详细信息，并在我的类路径中读取它，但是我无法加载该文件.这是我的代码:

I have written AWS lambda function in that i want to read database connection details from property file and which in my classpath, but I am not able to load that file.Here is my code:

InputStream input = DBConfiguartion.class.getResourceAsStream("appsettings");

        Reader r = new InputStreamReader(input, "UTF-8");
        Properties prop = new Properties();
        prop.load(r);

如果我当时通过正常的Java控制台应用程序运行此代码，则该代码正常工作，但是每当我将其作为AWS lambda函数运行时， InputStream 为空.

If I run this code through normal java console application that time it is working, but whenever i run it as AWS lambda function then InputStream is coming null.

推荐答案

您只有一个字符.这是一个工作示例，我必须做同样的事情:

You are only one character off. Here's a working example that I have to do the same thing:

InputStream is = DBConfiguartion.class.getResourceAsStream("/lambda.properties");
Properties properties = new Properties();
properties.load(is);

在构建部署jar时，它可与以下maven文件结构一起使用:

This works with the following maven file structure when building the deployment jar:

• 项目
• project/src/main/java
• project/src/main/java/com/something/DBConfiguartion.java-
• project/src/main/resources
• project/src/main/resources/lambda.properties
