Spring Boot解析自定义配置文件（yaml）

一、新建Spring Boot项目

      怎么建问度娘，这里只说解析的事

      

 

二、添加配置文件

      在resources下添加文件夹config，在此文件夹下新建配置文件serviceConfig.yml, 输入以下内容：

app:
  name: myService
  description: test read yaml file
  create: 20180712

 三、在com.isoft.centerserver下新建包common, 并新建类ServiceConfig.java，如下：

@ConfigurationProperties(prefix = "app") //节点名称
@PropertySource(value = {"classpath:config/serviceConfig.yml"}) //文件路径及文件名称一定要对哦
@Value("${配置文件中app下对应的字段名称}")

package com.isoft.centerserver.common;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;

/**
 * Created by Administrator on 2018/7/12.
 */
@Component
@ConfigurationProperties(prefix = "app")
@PropertySource(value = {"classpath:config/serviceConfig.yml"})
public class ServiceConfig
{
    public String getName()
    {
        return name;
    }

    public void setName(String name)
    {
        this.name = name;
    }

    public String getDescription()
    {
        return description;
    }

    public void setDescription(String description)
    {
        this.description = description;
    }

    public String getCreateTime()
    {
        return createTime;
    }

    public void setCreateTime(String createTime)
    {
        this.createTime = createTime;
    }

    @Value("${name}")
    private String name;

    @Value("${description}")
    private String description;

    @Value("${create}")
    private String createTime;
}

四、应用配置

将上面的配置类注入到controller中，具体如下：

package com.isoft.centerserver.controller;

import com.isoft.centerserver.common.ServiceConfig;
import net.sf.json.JSONObject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Administrator on 2018/7/12.
 */
@RestController
public class HealthController
{
    @Autowired
    private ServiceConfig serviceConfig;

    @RequestMapping(value = "/health", method = RequestMethod.GET)
    public JSONObject health()
    {
        JSONObject result = new JSONObject();
        result.put("status", 200);
        result.put("description", this.serviceConfig.getDescription());
        result.put("name", this.serviceConfig.getName());

        return result;
    }
}

五、测试结果：
