        <dependency>

            <groupId>org.springframework.boot</groupId>

yml:

user:

   name: lisa

   postcode: 610424199612112800

user.java方式一：使用@ConfigurationProperties注解实现批量对应属性值

package com.pecool.customer.entity;

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

import org.springframework.stereotype.Component;

@Component

@ConfigurationProperties(prefix="user")

public class User {

    private String name;

    private String postcode;

    public String getName() {

        return name;

    }

    public void setName(String name) {

        this.name = name;

    }

    public String getPostcode() {

        return postcode;

    }

    public void setPostcode(String postcode) {

        this.postcode = postcode;

    }

    @Override

    public String toString() {

        return "User [name=" + name + ", postcode=" + postcode + "]";

    }

}

user.java方式二：在属性上使用spring 的@Value注解也可以获取到yml或properties中的值

package com.pecool.customer.entity;

import org.springframework.beans.factory.annotation.Value;

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

import org.springframework.stereotype.Component;

@Component

//@ConfigurationProperties(prefix="user")

public class User {

    @Value("${user.name}")

    private String name;

    @Value("${user.postcode}")

    private String postcode;

    public String getName() {

        return name;

    }

    public void setName(String name) {

        this.name = name;

    }

    public String getPostcode() {

        return postcode;

    }

    public void setPostcode(String postcode) {

        this.postcode = postcode;

    }

    @Override

    public String toString() {

        return "User [name=" + name + ", postcode=" + postcode + "]";

    }

}

Test.java

package com.pecool;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.context.junit4.SpringRunner;

import com.pecool.customer.entity.User;

@SpringBootTest

@RunWith(SpringRunner.class)

public class TestA {

    @Autowired

    private User user;

    @Test

    public void xxx(){

        System.out.println(user);

    }

}
