person.age6
person.sexmale 2.新建一个类#xff0c;自动读取对应字段的值 有两种方式#xff0c; 第一种 package cn.wq;import org.springframework.beans.factory.… 首先新建一个springboot项目此处省略。 1.新建一个application.properties person.namekevin
person.age6
person.sexmale 2.新建一个类自动读取对应字段的值 有两种方式 第一种 package cn.wq;import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;Configuration
EnableConfigurationProperties
PropertySource(classpath:application.properties)
public class Person2Properties {Value(${person.name})private String name;Value(${person.age})private String age;Value(${person.sex})private String sex;public String getName() {return name;}public void setName(String name) {this.name name;}public String getAge() {return age;}public void setAge(String age) {this.age age;}public String getSex() {return sex;}public void setSex(String sex) {this.sex sex;}
} 第二种 package cn.wq;import org.springframework.boot.context.properties.ConfigurationProperties;ConfigurationProperties(prefix person) /*如果使用prefix则属性名中不能使用Value来注解,但是必须在spring启动时添加注解 EnableConfigurationProperties(PersonProperties.class)*/
public class PersonProperties {private String name;private String age;private String sex;public String getName() {return name;}public void setName(String name) {this.name name;}public String getAge() {return age;}public void setAge(String age) {this.age age;}public String getSex() {return sex;}public void setSex(String sex) {this.sex sex;}
} 3.启动主程序 package cn.wq;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Configuration;Configuration
EnableConfigurationProperties(PersonProperties.class)
SpringBootApplication
public class Application2 implements CommandLineRunner {public static void main(String[] args){SpringApplication.run(Application2.class,args);}AutowiredPersonProperties personProperties;AutowiredPerson2Properties person2Properties;Overridepublic void run(String... args) {System.out.println(程序实际上的入口在这里。);System.out.println(name:personProperties.getName());System.out.println(age:personProperties.getAge());System.out.println(sex:personProperties.getSex());System.out.println(2-name:person2Properties.getName());System.out.println(2-age:person2Properties.getAge());System.out.println(2-sex:person2Properties.getSex());}
} 4.运行输出结果 . ____ _ __ _ _/\\ / ____ __ _ _(_)_ __ __ _ \ \ \ \
