Spring Boot 中 yml 配置、引用其它 yml 中的配置。# 在配置文件目录（如：resources）下新建application-xxx
项目结构文件
server:
port: 8088
application:
name: VipSoft Env Demo
spring:
profiles:
include:
dic # 在配置文件目录（如：resources）下新建application-xxx 开头的yml文件，多个文件用 "," 号分隔，不能换行
#性别字典
user-gender:
0: 未知
1: 男
2: 女
application-dic.yml
将字典独立到单独的yml文件中
#支付方式
pay-type:
1: 微信支付
2: 货到付款
在 resources 目录下，创建META-INF目录，创建 spring.factories文件，
Spring Factories是一种类似于Java SPI的机制，它在META-INF/spring.factories文件中配置接口的实现类名称，然后在程序中读取这些配置文件并实例化。
内容如下:
# Environment Post Processor
org.springframework.boot.env.EnvironmentPostProcessor=com.vipsoft.web.utils.ConfigUtil
ConfigUtil
package com.vipsoft.web.utils;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.context.properties.bind.BindResult;
import org.springframework.boot.context.properties.bind.Binder;
import org.springframework.boot.env.EnvironmentPostProcessor;
import org.springframework.core.env.ConfigurableEnvironment;
import org.springframework.core.env.PropertySource;
import org.springframework.util.Assert;
public class ConfigUtil implements EnvironmentPostProcessor {
private static Binder binder;
private static ConfigurableEnvironment environment;
public static String getString(String key {
Assert.notNull(environment, "environment 还未初始化！";
return environment.getProperty(key, String.class, "";
}
public static <T> T bindProperties(String prefix, Class<T> clazz {
Assert.notNull(prefix, "prefix 不能为空";
Assert.notNull(clazz, "class 不能为空";
BindResult<T> result = ConfigUtil.binder.bind(prefix, clazz;
return result.isBound( ? result.get( : null;
}
/**
* 通过 META-INF/spring.factories，触发该方法的执行，进行环境变量的加载
*/
@Override
public void postProcessEnvironment(ConfigurableEnvironment environment, SpringApplication application {
for (PropertySource<?> propertySource : environment.getPropertySources( {
if (propertySource.getName(.equals("refreshArgs" {
return;
}
}
ConfigUtil.environment = environment;
ConfigUtil.binder = Binder.get(environment;
}
}
DictVo
package com.vipsoft.web.vo;
public class DictVO implements java.io.Serializable {
private static final long serialVersionUID = 379963436836338904L;
/**
* 字典类型
*/
private String type;
/**
* 字典编码
*/
private String code;
/**
* 字典值
*/
private String value;
public DictVO(String code, String value {
this.code = code;
this.value = value;
}
public String getType( {
return type;
}
public void setType(String type {
this.type = type;
}
public String getCode( {
return code;
}
public void setCode(String code {
this.code = code;
}
public String getValue( {
return value;
}
public void setValue(String value {
this.value = value;
}
}
DefaultController
package com.vipsoft.web.controller;
import com.vipsoft.web.utils.ConfigUtil;
import com.vipsoft.web.vo.DictVO;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
import java.util.ArrayList;
import java.util.LinkedHashMap;
import java.util.List;
@RestController
public class DefaultController {
@GetMapping(value = "/"
public String login( {
return "VipSoft Demo !!!";
}
@GetMapping("/list/{type}"
public List<DictVO> listDic(@PathVariable("type" String type {
LinkedHashMap dict = ConfigUtil.bindProperties(type.replaceAll("_", "-", LinkedHashMap.class;
List<DictVO> list = new ArrayList<>(;
if (dict == null || dict.isEmpty( {
return list;
}
dict.forEach((key, value -> list.add(new DictVO(key.toString(, value.toString(;
return list;
}
}
运行效果
