1.是指就在application.yml文件里面获取里面属性 的值

再写一个配置类

package com.borya.config;
    
    /**
     * 描述:
     * 发送邮件配置类
     *
     * @outhor 马铭泽
     * @create 2019-06-12 10:24
     */
    
    
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.stereotype.Component;
    
    
    
    @Component
    @ConfigurationProperties(prefix = "email")
    public class SendEmail {
        //发送时间
      private String time;
        //接受邮箱
        private String toEmail;
        //抄收邮箱
        private String ccEmail;
        //发送邮箱
        private String formEmail;
        //发送邮箱密码
        private String password;
    
    
      public String getTime() {
        return time;
      }
    
      public void setTime(String time) {
        this.time = time;
      }
    
      public String getToEmail() {
        return toEmail;
      }
    
      public void setToEmail(String toEmail) {
        this.toEmail = toEmail;
      }
    
      public String getCcEmail() {
        return ccEmail;
      }
    
      public void setCcEmail(String ccEmail) {
        this.ccEmail = ccEmail;
      }
    
      public String getFormEmail() {
        return formEmail;
      }
    
      public void setFormEmail(String formEmail) {
        this.formEmail = formEmail;
      }
    
      public String getPassword() {
        return password;
      }
    
      public void setPassword(String password) {
        this.password = password;
      }
    
      @Override
      public String toString() {
        return "SendEmail{" +
                "time='" + time + '\'' +
                ", toEmail='" + toEmail + '\'' +
                ", ccEmail='" + ccEmail + '\'' +
                ", formEmail='" + formEmail + '\'' +
                ", password='" + password + '\'' +
                '}';
      }
    }

主要的是上面的这个  
@Component  
@ConfigurationProperties (prefix = “你的名字”)  
这两个配置这样就可以根据自己所有的名字做出修改

或者这样的方式就可以获取yml文件里面的值了

2.获取别的配置文件里面的值：

同上文一样只是会增加一个@PropertySource(value = “sendemail.properties”)的注解表名位置

然后用同样的方式就可以获取到配置文件里面的值了：

大概就这两种方式。
