SpringBoot Series @PropertySource Usage Profile

SpringBoot Series @PropertySource Usage Profile

Following the blog post: SpringBoot Series @Value and @ConfigurationProperties contrast usage after, the blog continues to introduce usage @PropertySource annotations, through knowledge on a blog, you can know @Value and @ConfigurationProperties can be used to obtain a configuration file property value, but there is a detail easily overlooked, and that is, these two notes are to get the default profile property values in Springboot project, that is, the property value application.yml or application.properties

But we want with attributes, certainly can not go all the default configuration files in the stack, if you want to refer to attribute values ​​for other configuration files, you can use @PropertySource notes described in this blog

User.properties a new configuration file:

user.userName= root
user.isAdmin= true
user.regTime= 2019/11/01
user.isOnline= 1
user.maps.k1=v1
user.maps.k2=v2
user.lists=list1,list2
user.address.tel= 15899988899
user.address.name=上海

Use @PropertySource ( "classpath: user.properties") corresponding to the acquired properties file, then @ConfigurationProperties (prefix = "user") attribute mapping

package org.muses.jeeplatform.bean;

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

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

@Component
@PropertySource("classpath:user.properties")
@ConfigurationProperties(prefix = "user")
public class User {

    private String userName;
    private boolean isAdmin;
    private Date regTime;
    private Long isOnline;
    private Map<String,Object> maps;
    private List<Object> lists;
    private Address address;

    @Override
    public String toString() {
        return "User{" +
                       "userName='" + userName + '\'' +
                       ", isAdmin=" + isAdmin +
                       ", regTime=" + regTime +
                       ", isOnline=" + isOnline +
                       ", maps=" + maps +
                       ", lists=" + lists +
                       ", address=" + address +
                       '}';
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public boolean isAdmin() {
        return isAdmin;
    }

    public void setAdmin(boolean admin) {
        isAdmin = admin;
    }

    public Date getRegTime() {
        return regTime;
    }

    public void setRegTime(Date regTime) {
        this.regTime = regTime;
    }

    public Long getIsOnline() {
        return isOnline;
    }

    public void setIsOnline(Long isOnline) {
        this.isOnline = isOnline;
    }

    public Map<String, Object> getMaps() {
        return maps;
    }

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

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

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

    public Address getAddress() {
        return address;
    }

    public void setAddress(Address address) {
        this.address = address;
    }
}

Address class corresponding to:

package org.muses.jeeplatform.bean;

/**
 * <pre>
 *
 * </pre>
 *
 * @author nicky
 * <pre>
 * 修改记录
 *    修改后版本:     修改人：  修改日期: 2019年11月03日  修改内容:
 * </pre>
 */
public class Address {
    private String tel;
    private String name;

    @Override
    public String toString() {
        return "Address{" +
                       "tel='" + tel + '\'' +
                       ", name='" + name + '\'' +
                       '}';
    }

    public String getTel() {
        return tel;
    }

    public void setTel(String tel) {
        this.tel = tel;
    }

    public String getName() {
        return name;
    }

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

Write a junit test class

package org.muses.jeeplatform;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.muses.jeeplatform.bean.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@org.springframework.boot.test.context.SpringBootTest
public class SpringBootTest {

    @Autowired
    User user;

    @Test
    public void testConfigurationProperties(){
        System.out.println(user);
    }

}

Reading success, would not be written in the default configuration in the application.properties

User{userName='root', isAdmin=false, regTime=Fri Nov 01 00:00:00 CST 2019, isOnline=1, maps={k1=v1, k2=v2}, lists=[list1, list2], address=Address{tel='15899988899', name='上海市'}}

Note: For @PropertySource notes, the default configuration file is not supported yml read, need to be modified before they can rewrite
