Spring Boot - 使用 Constants 类读取自定义属性文件 [英] Spring Boot - Read custom properties file using Constants class

问题描述

我有一个常量类，其中定义了所有常量.常量的值位于我的自定义属性文件中，而属性文件位于一个包中.我正在尝试使用我的 Constants 类读取自定义属性文件中的值.

I am having a constants class wherein all the Constants have been defined. The values for the constants lies in my custom properties file and the property file resides in a package. I am trying to read the value in the custom property file using my Constants class.

我的常量类

package com.example.demo.properties

public interface AppConstant {
//my custom constants
String REQUEST_SUCCESS = "REQUEST_SUCCESS";
String INTERNAL_ERROR = "INTERNAL_ERROR";
String REQUEST_FAIL = "REQUEST_FAIL";
}

AppProps.properties

AppProps.properties

//values for constants in properties file
//package com.example.demo.properties
REQUEST_SUCCESS = Request was successful
INTERNAL_ERROR = Internal Error
REQUEST_FAIL = Request Failed due to error

我正在尝试使用 java.util.Properties 读取属性文件.有人可以告诉我如何使用 Spring Boot 注释读取值.

I am trying to read the properties file using java.util.Properties. Can someone show me how the value can be read using Spring Boot annotations.

推荐答案

将 AppProps.properties 文件添加到 resources 文件夹，然后在类上方添加以下注释想使用属性

Add AppProps.properties file to the resources folder and then add below annotation to above your class that want to use properties

@PropertySource("classpath:AppProps.properties")

然后使用 Value 注释，如下所示:

and then use Value annotation like below:

@Value("${REQUEST_SUCCESS}")
private String requestSuccess;
