SpringBoot读取自定义配置文件

不引入依赖(spring-boot-configuration-processor)数组获取方式引入依赖(spring-boot-configuration-processor)懒人版配置自定义配置

不引入依赖(spring-boot-configuration-processor)

数组获取方式

准备my.properties和my.yml

list1=11111,1,2321,4,4325,645,/sahnd/dsauyuw

list2: >dsadsad,fdsewrwar,sdaadsadsadsa

ProConfig

import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.PropertySource;import java.util.List;/*** TODO** @author WJM* @description* @date /4/10 10:13*/@Data@AllArgsConstructor@NoArgsConstructor@Configuration@PropertySource("classpath:/my.properties")public class ProConfig {@Value("#{'${list1}'.split(',')}")private List<String> list1;}

读取自定义yml需要创建一个类

YamlPropertySourceFactory

import org.springframework.beans.factory.config.YamlPropertiesFactoryBean;import org.springframework.core.env.PropertiesPropertySource;import org.springframework.core.env.PropertySource;import org.springframework.core.io.support.EncodedResource;import org.springframework.core.io.support.PropertySourceFactory;import java.io.FileNotFoundException;import java.io.IOException;import java.util.Properties;/*** TODO** @author WJM* @description* @date /4/10 10:35*/public class YamlPropertySourceFactory implements PropertySourceFactory {//这个方法有2个入参，分别为资源名称和资源对象，这是第一步@Overridepublic PropertySource< ? > createPropertySource(String name, EncodedResource resource) throws IOException {//这是第二步，根据流对象产出Properties对象Properties propertiesFromYaml = loadYamlIntoProperties(resource);String sourceName = name != null ? name : resource.getResource().getFilename();assert sourceName != null;//这是第三部，根据Properties对象，产出PropertySource对象，放入到Spring中return new PropertiesPropertySource(sourceName, propertiesFromYaml);}private Properties loadYamlIntoProperties(EncodedResource resource) throws FileNotFoundException {try {YamlPropertiesFactoryBean factory = new YamlPropertiesFactoryBean();factory.setResources(resource.getResource());factory.afterPropertiesSet();return factory.getObject();} catch (IllegalStateException e) {Throwable cause = e.getCause();if (cause instanceof FileNotFoundException) {throw (FileNotFoundException) e.getCause();}throw e;}}}

YmlConfig

import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.PropertySource;import java.util.List;/*** TODO** @author WJM* @description* @date /4/10 10:29*/@Data@AllArgsConstructor@NoArgsConstructor@Configuration@PropertySource(factory =YamlPropertySourceFactory.class,value = "classpath:my.yml")public class YmlConfig {@Value("${list2}")private List<String> list2;}

Test读取

@SpringBootTestclass MyPropertiesApplicationTests {@Resourceprivate ProConfig proConfig;@Resourceprivate YmlConfig ymlConfig;@Testvoid contextLoads() {System.out.println(ymlConfig.toString());System.out.println(proConfig.toString());}}

结果

YmlConfig{list=[dsadsad, fdsewrwar, sdaadsadsadsa]}
ProConfig{list=[11111, 1, 2321, 4, 4325, 645, /sahnd/dsauyuw]}

注：Map暂时搞不清楚，请使用一对一的JavaBean

引入依赖(spring-boot-configuration-processor)

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><optional>true</optional></dependency>

注：使用@ConfigurationProperties(prefix = “前缀”)需要添加前缀

懒人版配置

新建一个application-my.yml或者application-my.properties

在application.yml或者application.properties加

ymlspring:profiles:include: my--------------------------------------propertiesspring.profiles.include=my

application-my.yml

yml:name: 张三map:name: sagdwaage: 18sex: 0list3:- dsajhdsa- dsjahjdhwa- dshjgahjghwur- dsujahuwdw

application-my1.properties

pro.map.name=张三pro.map.age=18pro.map.sex=0pro.list4[0]=hjsahjdhjsapro.list4[1]=dwadasfwafpro.list4[2]=fsdadwadpro.list4[3]=ewqrsafsa

ProConfig

import lombok.AllArgsConstructor;import lombok.Data;import lombok.NoArgsConstructor;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.Configuration;import java.util.List;import java.util.Map;/*** TODO** @author WJM* @description* @date /4/10 10:13*/@Data@AllArgsConstructor@NoArgsConstructor@Configuration@ConfigurationProperties(prefix = "pro")//@PropertySource("classpath:/my.properties")public class ProConfig {private Map<String, String> map;private List<String> list4;}

YmlConfig

import lombok.AllArgsConstructor;import lombok.Data;import lombok.NoArgsConstructor;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.Configuration;import java.util.List;import java.util.Map;/*** TODO** @author WJM* @description* @date /4/10 10:29*/@Data@AllArgsConstructor@NoArgsConstructor@Configuration@ConfigurationProperties(prefix = "yml")//@PropertySource(factory =YamlPropertySourceFactory.class,value = "classpath:my.yml")public class YmlConfig {private Map<String, String> map;private List<String> list3;}

Test输出结果

YmlConfig(map={name=sagdwa, age=18, sex=0}, list3=[dsajhdsa, dsjahjdhwa, dshjgahjghwur, dsujahuwdw])
ProConfig(map={name=张三, age=18, sex=0}, list4=[hjsahjdhjsa, dwadasfwaf, fsdadwad, ewqrsafsa])
