java - 我无法从 java spring boot 中的属性访问数据

Question

我有名为 application-QA1.properties 的属性

#Endpoint
web.loginPage=https://www.phptravels.net/

#login data
common.data.username=tes
common.data.password=tes

#Default Param
param.storeId=10001
param.channelId=tes-web
param.clientId=10001
param.requestId=RANDOM
param.businessChannel=web
param.requestParams={}
param.test=true

我把它放进去:

src/test/resources

我创建类作为名为 WebProperties.java 的属性的实例

package com.project.automation.ui.properties;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Data
@Component("com.project.automation.ui.properties.WebProperties")
@ConfigurationProperties(prefix = "web")
public class WebProperties {
    private String loginPage;
}

我把它放进去:

src/main/java/mypackage/properties

我想访问 LoginPage.java 上的类变量

package com.project.automation.ui.pages;

import com.project.automation.ui.models.xpath.CommonXpathModel;
import com.project.automation.ui.properties.CommonProperties;
import com.project.automation.ui.properties.WebProperties;
import lombok.Data;
import net.serenitybdd.core.pages.PageObject;
import org.openqa.selenium.By;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Data
@Component("com.project.automation.ui.pages.LoginPage")
public class LoginPage extends PageObject {

  @Autowired
  CommonPage commonPage;

  @Autowired
  CommonXpathModel commonXpathModel;

  @Autowired
  WebProperties webProperties;

  @Autowired
  CommonProperties commonProperties;

  public void openPage(){
    //on this code i want to get that properties value through its class instance
    getDriver().get(webProperties.getLoginPage());
  }
}

我放入的页面:

src/main/java/mypackage/pages

这是我的 pom.xml，位于我的项目根目录中。

但它一直返回null。

请帮助我，我已经阅读了很多教程，但仍然没有运气，而且我是 Spring Boot 的初学者。谢谢

Answer 1

问题是属性文件的命名约定，由于您将其命名为application-QA1.properties，它成为配置文件特定的属性文件 Profile-specific properties您可以通过在 application.properties 中激活配置文件来加载这些属性，例如 here

spring.profiles.active=QA1

或者通过命令行

java -jar myproject.jar --spring.profiles.active=QA1

还有一个信息，@Component注解中的值表示bean名称

he value may indicate a suggestion for a logical component name, to be turned into a Spring bean in case of an autodetected component.
