SpringBoot读取两种格式的配置文件(xml/yml)

一般情况下我们常用Enventment读取配置，读取.properties，本篇文章主要从
.properties和.yml文件来分析如何使用.也谈不上分析，直接上代码，一看就会了。如果不会yml的同学，直接看代码也能看懂了(规则是死的会用就ok)

• 首先引入依赖

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

读取.properties

master.ds.url=jdbc:mysql://localhost:3306/test
master.ds.username=root
master.ds.password=root

      @ConfigurationProperties(prefix = "master.ds",locations = "classpath:application.properties")
      public class PropsConfig {
         private String url;
         private String username;
         private String password;
      }
  
 

读取yml

      myProps: #自定义的属性和值
        simpleProp: simplePropValue
        arrayProps: 1,2,3,4,5
        listProp1:
          - name: abc
            value: abcValue
          - name: efg
            value: efgValue
        listProp2:
          - config2Value1
          - config2Vavlue2
        mapProps:
          key1: value1
          key2: value2
  
 

      @ConfigurationProperties(prefix="myProps") //application.yml中的myProps下的属性
      public class YmlConfig {
         private String simpleProp;
         private String[] arrayProps;
         private List<Map<String, String>> listProp1 = new ArrayList<>(); //接收prop1里面的属性值
         private List<String> listProp2 = new ArrayList<>(); //接收prop2里面的属性值
         private Map<String, String> mapProps = new HashMap<>(); //接收prop1里面的属性值
