SpringBoot读取配置文件的方式

SpringBoot读取配置文件的方式

application.yml

	my.name: dada

使用Environment方式

	@RequestMapping("/test")
	@RestController
	public class UserController {

 		@Autowired
 		private Environment env;
 		
	    @GetMapping("/hello")
	    public String hello(){
	        String name = env.getProperty("my.name");
	        return  name;
	    }

使用@Vaule方式

@RequestMapping("/test")
	@RestController
	public class UserController {

 		 @Value("${my.name}")
   		 String name;
 		
	    @GetMapping("/hello")
	    public String hello(){
	        return  name;
	    }

使用prefix方式

MyConfig.class

package com.dada.config;

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

/**
 * 〈配置类〉
 *
 * @author hupengda
 * @create 2019/1/10
 */
@ConfigurationProperties(prefix = "my")
@Component
public class MyConfig {

    String name;

    public String getName() {
        return name;
    }

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

UserController

@RequestMapping("/test")
	@RestController
	public class UserController {

 		 @Autowired
  		 MyConfig myConfig;
 		
	    @GetMapping("/hello3")
	    public String hello3(){
	        return  myConfig.getName();
	    }
