無法使用java配置訪問屬性文件中的所有屬性？

Question

使用Java配置（@ConfigurationProperties）我只能訪問單個字屬性，如果我想訪問帶后綴的屬性（例如：server.port，server.address）我需要將服務器添加到配置中（ @ConfigurationProperties（“server”） ）。

我需要屬性文件中的所有屬性如何訪問它？

//application.properties
spring.application.name=com-example
server.port=8080
minimum=200
maximum=20000

//Configuration.java

package com.example;

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

@Component
@ConfigurationProperties("server")
public class Configuration {
    private int minimum;
    private int maximum;
    private int port;

    public int getPort() {
        return port;
    }

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

    protected Configuration() {

    }

    public Configuration(int minimum, int maximum, int port) {
        super();
        this.minimum = minimum;
        this.maximum = maximum;
        this.port = port;
    }

    public int getMinimum() {
        return minimum;
    }

    public void setMinimum(int minimum) {
        this.minimum = minimum;
    }

    public int getMaximum() {
        return maximum;
    }

    public void setMaximum(int maximum) {
        this.maximum = maximum;
    }

}

//ExampleController.java

package com.example;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ExampleController {

    @Autowired
    private Configuration configuration;

    @GetMapping("/properties")
    public Configuration getConfiguration() {
        return new Configuration(configuration.getMinimum(), configuration.getMaximum(),
                configuration.getPort());
    }
}

Answer 1

嘗試這個：

@Component
@Configuration
public class Configuration {
    @Value("${minimum}")
    private int minimum;

    @Value("${maximum}")
    private int maximum;

    @Value("${server.port}")
    private int port;

    //Methods
}

根據Configuration它可能是名稱沖突。
