Spring Boot全局配置文件详解_springboot设置is

一. 全局配置文件概述及优先级

–file: ./config/

–file: ./

–classpath: /config/

–classpath: /

翻译成语言如下（ 按照优先级从高到低的顺序 ）：

 

 

$ java -jar myproject.jar --spring .config .name = myproject

java -jar run-0.0.1-SNAPSHOT.jar --

spring .config .location = D:/application.properties

二. application.properties配置文件

package com.lagou.pojo;
 
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
 
import java.util.Arrays;
import java.util.List;
import java.util.Map;
 
@Component
@ConfigurationProperties(prefix = "person")   //实现批量注入（set方法）
public class Person {
 
    private int id;            //id
    private String name;      //名称
    private List hobby;       //爱好
    private String[] family; //家庭成员
    private Map map;
    private Pet pet;          //宠物
 
    public int getId() {
        return id;
    }
 
    public void setId(int id) {
        this.id = id;
    }
 
    public String getName() {
        return name;
    }
 
    public void setName(String name) {
        this.name = name;
    }
 
    public List getHobby() {
        return hobby;
    }
 
    public void setHobby(List hobby) {
        this.hobby = hobby;
    }
 
    public String[] getFamily() {
        return family;
    }
 
    public void setFamily(String[] family) {
        this.family = family;
    }
 
    public Map getMap() {
        return map;
    }
 
    public void setMap(Map map) {
        this.map = map;
    }
 
    public Pet getPet() {
        return pet;
    }
 
    public void setPet(Pet pet) {
        this.pet = pet;
    }
 
    @Override
    public String toString() {
        return "Person{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", hobby=" + hobby +
                ", family=" + Arrays.toString(family) +
                ", map=" + map +
                ", pet=" + pet +
                '}';
    }
}

package com.lagou.pojo;
 
public class Pet {
 
    // 类型
    private String type;
    // 名称
    private String name;
 
    public String getType() {
        return type;
    }
 
    public void setType(String type) {
        this.type = type;
    }
 
    public String getName() {
        return name;
    }
 
    public void setName(String name) {
        this.name = name;
    }
 
    @Override
    public String toString() {
        return "Pet{" +
                "type='" + type + '\'' +
                ", name='" + name + '\'' +
                '}';
    }
}

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <optional>true</optional>
        </dependency>

@RunWith(SpringRunner.class)
@SpringBootTest
class Springboot01DemoApplicationTests {
 
    @Autowired
    private Person person;
 
 
    @Test
    void contextLoads() {
        System.out.println(person);
    }
}

 YAML文件的扩展名可以使用.yml或者.yaml。

application.yml 文件使用 “key: （空格） value” 格式配置属性，使用缩进控制层级关系。

（2）value值为数组和单列集合

person :

    hobby :

       play,

       read,

       sleep
