Spring PropertySource，获取指定application.properties文件

@PropertySource注解的使用

• @PropeertySource，指定加载配置文件
  • 配置文件映射到实体类
• 使用@Value映射到具体的java属性

CustomConfig.java

package net.cybclass.sp.aop;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;

@Configuration
@PropertySource(value = "classpath:config.properties")
public class CustomConfig {
    @Value("${server.host}")
    private String host;
    @Value("${server.port}")
    private int port;

    public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }

    @Override
    public String toString() {
        return "CustomConfig{" +
                "host='" + host + '\'' +
                ", port=" + port +
                '}';
    }
}
