SpringBoot项目获取统一前缀配置及获取非确定名称配置方法
作者:gooluke
在SpringBoot项目中,使用@ConfigurationProperties注解可获取统一前缀的配置,具体做法是创建配置类,使用prefix属性指定配置的前缀,本文给大家介绍SpringBoot项目获取统一前缀配置以及获取非确定名称配置方法,感兴趣的朋友跟随小编一起看看吧
SpringBoot项目获取统一前缀配置以及获取非确定名称配置
在SpringBoot项目中,我们经常看到统一前缀的配置,我们该怎么统一获取
my.config.a.name=xiaoming
my.config.a.age=18
my.config.a.address=guangdongmy.config.b.name=xiaomli
my.config.b.age=20
my.config.b.address=shandong
方式一:使用对应的配置类并结合注解:@ConfigurationProperties(prefix = “xxx.xxx”)
配置文件:
my.config.name=xiaoming my.config.age=18 my.config.address=guangdong
对应的配置类:MyProperties
import lombok.Getter; import lombok.Setter; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.stereotype.Component; /** * @author gooluke */ @Component @ConfigurationProperties(prefix = "my.config") @Getter @Setter public class MyProperties { private String name; private int age; private String address; }
获取配置类,打印属性:
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping("/test") public class TestController { @Autowired private MyProperties myProperties; @RequestMapping("/show") public void show() { System.out.println("myProperties.getName() = " + myProperties.getName()); System.out.println("myProperties.getAge() = " + myProperties.getAge()); System.out.println("myProperties.getAddress() = " + myProperties.getAddress()); } }
打印结果:
方式二:获取统一前缀,而后面非确定字段名的配置
配置文件:
my.config.a.name=xiaoming my.config.a.age=18 my.config.a.address=guangdong my.config.b.name=xiaomli my.config.b.age=20 my.config.b.address=shandong
对应的配置类:
import lombok.Getter; import lombok.Setter; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.stereotype.Component; import java.util.Map; /** * @author gooluke */ @Component @ConfigurationProperties(prefix = "my") @Getter @Setter public class MyProperties2 { //这里的config得对应上my.config.xx里的config private Map<String, UserInfoConfig> config; @Setter @Getter public static class UserInfoConfig { private String name; private Integer age; private String address; } }
获取配置类,打印属性:
@Autowired private MyProperties2 myProperties2; @RequestMapping("/show2") public void show2() { Map<String, MyProperties2.UserInfoConfig> config = myProperties2.getConfig(); config.forEach((user, userInfoConfig) -> { System.out.println("user = " + user); System.out.println("userInfoConfig.getName() = " + userInfoConfig.getName()); System.out.println("userInfoConfig.getAge() = " + userInfoConfig.getAge()); System.out.println("userInfoConfig.getAddress() = " + userInfoConfig.getAddress()); }); }
打印结果:
