• 读取appliaction.properties里面的端口数据

@Value方式

@RestController
public class getText {
    //@value方式读取文件
    @Value("${server.port}")
    private String port;
    @GetMapping("getPort")
    public String getPort(){
        return port;
    }
}

使用ConfigurationProperties 配合类来实现

• 类

package com.example.spring.domain;


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

@ConfigurationProperties(prefix = "text")
@Component
public class ServerSettings {
    private String name;
    private String domain;

    public String getName() {
        return name;
    }

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

    public String getDomain() {
        return domain;
    }

    public void setDomain(String domain) {
        this.domain = domain;
    }
}

• 读取

    //读取项目域名
    @Autowired
    private ServerSettings serverSettings;

    @GetMapping("getServer")
    public Object getServer(){
        return serverSettings;
    }
