yaml的基本使用

yaml是鬆綁定的

my:
  my-baby: xiongda

my:
  myBaby: xiongda

my:
  my_baby: xiongda

yaml是鬆綁定的，也就意味着以上三種方式結果都是一致的

@Component
@ConfigurationProperties(prefix = "my")
public class Config {
	
	private String myBaby;

	public String getMyBaby() {
		return myBaby;
	}

	public void setMyBaby(String myBaby) {
		this.myBaby = myBaby;
	}
	
}

myBaby字段對應的內容都會被set爲 xiongda

幾種常見的類型

一、注入List

my:
  list: 
   - list1
   - list2

對應的數據類型

package com.example.demo;

import java.util.List;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "my")
public class Config {

	private List<String> list;

	public List<String> getList() {
		return list;
	}

	public void setList(List<String> list) {
		this.list = list;
	}
	
}

二、注入Map

my:
  map:
   name: xiongda
   age : 18

對應數據類型

package com.example.demo;

import java.util.List;
import java.util.Map;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "my")
public class Config {
	private Map<String, Object> map;

	public Map<String, Object> getMap() {
		return map;
	}

	public void setMap(Map<String, Object> map) {
		this.map = map;
	}
	
}

三、注入pojo

my:
  person:
   name: xiongda
   age : 18

對應數據類型

package com.example.demo;

import java.util.List;
import java.util.Map;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "my")
public class Config {
	private Person person;

	public Person getPerson() {
		return person;
	}

	public void setPerson(Person person) {
		this.person = person;
	}
}

四、List嵌入

my:
  lists:
   - [1,2,3]
   - [4,5,6]

對應數據類型

package com.example.demo;

import java.util.List;
import java.util.Map;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "my")
public class Config {
	private List<List<Integer>> lists;

	public List<List<Integer>> getLists() {
		return lists;
	}

	public void setLists(List<List<Integer>> lists) {
		this.lists = lists;
	}
	
}
