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
