    com.zyd.type3=Springboot - @ConfigurationProperties

**一、@ConfigurationProperties方式**

**自定义配置类：PropertiesConfig.java**

@Component 
    @ConfigurationProperties(prefix = "com.zyd")
    public class PropertiesConfig {
    	public String type3;
    	public String title3;
    	public Map<String, String> login = new HashMap<String, String>();
    	public List<String> urls = new ArrayList<>();
    
    	public String getType3() {
    		return type3;
    	}
    
    	public void setType3(String type3) {
    		this.type3 = type3;
    	}
    
    	public String getTitle3() {
    		try {
    			return new String(title3.getBytes("ISO-8859-1"), "UTF-8");
    		} catch (UnsupportedEncodingException e) {
    			e.printStackTrace();
    		}
    		return title3;
    	}
    
    	public void setTitle3(String title3) {
    		this.title3 = title3;
    	}
    
    	public Map<String, String> getLogin() {
    		return login;
    	}
    
    	public void setLogin(Map<String, String> login) {
    		this.login = login;
    	}
    
    	public List<String> getUrls() {
    		return urls;
    	}
    
    	public void setUrls(List<String> urls) {
    		this.urls = urls;
    	}
    }

### 另外一种方式： ###

自定义citycode.properties

#List properties
    citycode.list[0]=www
    citycode.list[1]=localhost
    citycode.list[2]=wuhan
    citycode.list[3]=tianjin
    
    
    #Map Properties
    citycode.map.www=4201
    citycode.map.wuhan=4201
    citycode.map.tianjin=1200

设置一个类去读取properties

import lombok.Data;
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.context.annotation.PropertySource;
    
    import java.util.ArrayList;
    import java.util.HashMap;
    import java.util.List;
    import java.util.Map;
    
    @Data
    @Configuration
    @PropertySource("classpath:citycode.properties")
    @ConfigurationProperties(prefix = "citycode")
    public class CityCodeConfig {
    
        private List<String> list = new ArrayList<>();
    
        private Map<String, String> map = new HashMap<>();
    
    }
