1、操作步骤

1.新建配置文件：

2.编辑配置文件：

test-server=rd-dev02.jr.rong360.com

3.新建Config类：

@Component
@PropertySource(value = "kirara.properties")
public class KiraraConfig {@Value("${test-server:rd-dev02.jr.rong360.com}")private String testServer;public String getTestServer() {return testServer;}public void setTestServer(String testServer) {this.testServer = testServer;}
}

4.编辑调用类：

@RestController
public class UuapLoginController {@Autowiredprivate UuapLoginService loginService;@Autowiredprivate KiraraConfig kiraraConfig;/*** 登录方法** @param loginBody 登录信息* @return 结果*/@PostMapping("/api/v1/login")public AjaxResult login() throws Exception{AjaxResult ajax = AjaxResult.success();kiraraConfig.getTestServer();return ajax;}
}

2、总结

主要是用Config类去加载配置文件内容，然后注入到类中进行使用。

3、扩展

Spring中加载ApplicationContext.xml的方法分享，如下所示:

spring 中加载xml配置文件的方式 有4种,分别为：
XmlBeanFactory,
ClassPathXmlApplicationContext,
FileSystemXmlApplicationContext,
XmlWebApplicationContext

扩展详情

4、第二种方法获取配置文件bean

1.配置实体类：

/*** 学生实体类* Created by ASUS on 2018/5/4*/@Component("Student")
public class Student {private String name;private  int age;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public Student(String name, int age) {this.name = name;this.age = age;}public Student() {}@Overridepublic String toString() {return "Student{" +"name='" + name + '\'' +", age=" + age +'}';}
}

2.启动类配置：

/*** springboot启动类**/@SpringBootApplication
//读取resources目录下的applicationContext.xml
@ImportResource("classpath:applicationContext.xml")
public class Application
{public static void main( String[] args ){ApplicationContext applicationContext= SpringApplication.run(Application.class,args);Student student= (Student) applicationContext.getBean("student",Student.class);System.out.println("message:"+student.toString());}}

3.application.xml的内容：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsd  "><bean name="student" class="springboot.entity.Student"><property name="name" value="小黄"/><property name="age" value="19"/></bean></beans>

4.测试结果：
