SpringBoot获取yml文件参数,超简单_env.getproperty获取yml自定义参数-优快云博客

本文介绍了一种从Spring Environment中读取YAML配置文件参数的方法，通过自定义GlobalProperties类，封装了常用参数，如server.port、server.context-path、数据库连接信息等，简化了系统对配置的访问。

application.yml文件中的参数其实都在Environment里,所以直接从Environment里读取即可.为方便起见,我自己写了一个参数文件,将常用的一些参数及Environment一并放到里面,方便系统使用;使用时直接用GlobalProperties.getEnv.getProperty("server.port")即可.参考代码如下:

package com.jeelite.modules.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.core.env.Environment;
import org.springframework.stereotype.Component;

@Component("GlobalProperties")
public class GlobalProperties {
   @Autowired
   private Environment environment;
   @Value("${server.port}")
   private String serverPort;
   @Value("${server.context-path}")
   private String serverName;
   @Value("${spring.datasource.driver-class-name}")
   private String driverClass;
   @Value("${spring.datasource.username}")
   private String username;
   @Value("${spring.datasource.password}")
   private String password;

   public String getServerPort() {
       return serverPort;
   }
   public void setServerPort(String serverPort) {
       this.serverPort = serverPort;
   }
   public String getServerName() {
       return serverName;
   }
   public void setServerName(String serverName) {
       this.serverName = serverName;
   }
   public String getDriverClass() {
       return driverClass;
   }
   public void setDriverClass(String driverClass) {
       this.driverClass = driverClass;
   }
   public String getUsername() {
       return username;
   }
   public void setUsername(String username) {
       this.username = username;
   }
   public String getPassword() {
       return password;
   }
   public void setPassword(String password) {
       this.password = password;
   }
   public Environment getEnv(){
       return environment;
   }
}
