springboot–属性配置02

spring默认的属性配置文件是：application.propertity
推荐使用application.yml

server:
  port: 8080
cupSize: F
girl:
  cupSize: G
  age: 22

GirlProperty.java

package com.rick;

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

/**
 * Created by rick on 2017/1/10.
 */

@ConfigurationProperties(prefix = "girl")
@Component
public class GirlProperty {

    private Integer age;

    private String cupSize;

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getCupSize() {
        return cupSize;
    }

    public void setCupSize(String cupSize) {
        this.cupSize = cupSize;
    }
}

属性使用HelloController.java

package com.rick;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;

/**
 * Created by rick on 2017/1/10.
 */

@RestController
public class HelloController {

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

    @Resource
    private GirlProperty girlProperty;

    @RequestMapping(value="/hello", method = RequestMethod.GET)
    public String sayHello() {        
        return girlProperty.getCupSize() + "=>" + girlProperty.getAge();

}
