NeoProperties.java

package com.neo.comm;

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

@Component
@ConfigurationProperties(prefix="neo")
public class NeoProperties {
    private String title;
    private String description;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }
}

OtherProperties.java

package com.neo.comm;

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

@Component
@ConfigurationProperties(prefix="other")
@PropertySource("classpath:other.properties")
public class OtherProperties {
    private String title;
    private String blog;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getBlog() {
        return blog;
    }

    public void setBlog(String blog) {
        this.blog = blog;
    }
}

获取：

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

 

import javax.annotation.Resource;

    
    @Value("${neo.title}")
    private String title;
    @Resource
    private NeoProperties properties;
    @Resource
    private OtherProperties otherProperties;

    System.out.println("title:"+properties.getTitle());
