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 {
@Autowired
private UuapLoginService loginService;
@Autowired
private 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() {
}
@Override
public 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/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://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:
