springboot 将yml文件内容注入javaBean

这是使用注解的方式分为两步：

1、编写 yml 文件

2、编写 javaBean 接收类

下面上代码： 

application.yml

myProps: #自定义的属性和值  
  simpleProp: simplePropValue  
  arrayProps: 1,2,3,4,5  
  listProp1:   #List中的元素是Map
    - name: abc  
      value: abcValue  
    - name: efg  
      value: efgValue  
  listProp2:  
    - config2Value1  
    - config2Vavlue2  
  mapProps:  
    key1: value1  
    key2: value2 

MyConfig.java

package testSpringBoot;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

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

@Component
// 不加这个注解的话, 使用@Autowired 就不能注入进去了
@ConfigurationProperties(prefix = "myProps")
// 配置文件中的前缀
public class MyConfig {
    private String simpleProp;  
    private String[] arrayProps;  
    private List> listProp1 = new ArrayList>(); //接收prop1里面的属性值,List中的元素是Map  
    private List listProp2 = new ArrayList(); //接收prop2里面的属性值  
    private Map mapProps = new HashMap(); //接收prop1里面的属性值

	public String getSimpleProp() {
		return simpleProp;
	}

	public void setSimpleProp(String simpleProp) {
		this.simpleProp = simpleProp;
	}

	public String[] getArrayProps() {
		return arrayProps;
	}

	public void setArrayProps(String[] arrayProps) {
		this.arrayProps = arrayProps;
	}

	public List> getListProp1() {
		return listProp1;
	}

	public void setListProp1(List> listProp1) {
		this.listProp1 = listProp1;
	}

	public Map getMapProps() {
		return mapProps;
	}

	public void setMapProps(Map mapProps) {
		this.mapProps = mapProps;
	}

	public List getListProp2() {
		return listProp2;
	}

	public void setListProp2(List listProp2) {
		this.listProp2 = listProp2;
	}

 
}
