import javax.annotation.Resource;


@Configuration // 标志为注解类
//@ConditionalOnWebApplication //是web类的时候加载
@EnableConfigurationProperties(HelloProperties.class) // 使得HelloProperties属性文件生效
public class AutoConfig {

    // 导入属性文件
    @Autowired
    private HelloProperties helloProperties;

    @Bean
    public HelloService helloService() {
        HelloService service = new HelloService();
        service.setHelloProperties(helloProperties);
        return service;
    }
}

package com.dyl;

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


@ConfigurationProperties(prefix = "example.hello") //  绑定配置文件中所有以example.hello开头的配置
public class HelloProperties {

    
    private String prefix;

    
    private String suffix;

    public String getPrefix() {
        return prefix;
    }

    public void setPrefix(String prefix) {
        this.prefix = prefix;
    }

    public String getSuffix() {
        return suffix;
    }

    public void setSuffix(String suffix) {
        this.suffix = suffix;
    }
}

package com.dyl;


public class HelloService {

    
    HelloProperties helloProperties;

    public String sayHello(String name) {

spring.factories

org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.dyl.AutoConfig

    1.0-SNAPSHOT

application.properties

example.hello.prefix = "EXAMPLE"
example.hello.suffix = "HELLO"

@Resource
HelloService helloService;

System.out.println(helloService.sayHello("dyl"));

Result:

"EXAMPLE"-dyl-"HELLO"
