Spring Boot-从外部属性文件设置值 [英] Spring Boot - set value from an external properties file

问题描述

我在application.properties上设置了以下外部位置

I have an external location set on my application.properties as below

spring.config.location=file:${catalina.home}/conf/app.properties

app.properties具有作为timeOut=10000的属性.还有许多其他属性.

app.properties has a property as timeOut=10000. There are many other properties as well.

我需要在会话中设置此属性，如下所示:

I need to set this property on my session something like this:

 session.setMaxInactiveInterval(timeOut_Property);

如何实现?

添加控制器:

@Controller
public class StartController  {

@Value("${spring.config.location.defaultTimeout}")
private int defaultTimeout;

@RequestMapping("login.do")
public String login(HttpServletRequest request, HttpSession session, Model model) {     
    session.setMaxInactiveInterval(defaultTimeout);     
    return null;        
}

推荐答案

您的主应用程序类应如下所示:

Your Main Application class should look like this:

@SpringBootApplication
@PropertySource(name = "general-properties", value = { "classpath:path to your app.properties"})
public class MainApplication {

    public static void main(String[] args) {
        SpringApplication.run(NayapayApplication.class, args);
    }
}

并将您的控制器更改为:

And change your controller to:

@Controller
public class StartController  {

    @Value("${timeOut}")
    private int defaultTimeout;

    @RequestMapping("login.do")
    public String login(HttpServletRequest request, HttpSession session, Model model) {     
        session.setMaxInactiveInterval(defaultTimeout);     
        return null;        
    }
}
