本文介绍了Springboot中的@Value返回null的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有位于资源中的application.properties
I have the application.properties, which is located in the resources
apllication.properties
hsm.provider=software
hsm.name=TestHsm
hsm.port=3001
hsm.ip=127.0.0.1
hsm.timeout=10000
和控制器
@RestController
@RequestMapping("/hsm")
public class Controller {
@Value("${hsm.ip}")
private String ip;
@Value("${hsm.port}")
private String port;
@Value("${hsm.name}")
private String name;
@Value("${hsm.timeout}")
private String timeout;
@Value("${hsm.provider}")
private String provider;}
}
但是,当我运行应用程序时,所有变量都为NULL.我想念什么?
however when i run application, all variables remain NULL. What am i missing?
编辑这是从src文件夹开始的项目结构
EDIT This is the projectstructure as of the src folder
src
├───main
│ ├───java
│ │ └───com
│ │ └───xyz
│ │ └───hsmservice
│ │ └───hsm
│ │ └───api
│ │ Application.java
│ │ Controller.java
│ │ HSM.java
│ │
│ └───resources
│ │ application.properties
│ │
│ └───META-INF
│ plugin.xml
│
└───test
├───java
│ LibraryTest.java
│
└───resources
编辑2 这是应用程序类
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
