SpringBoot获得application.properties中数据的值

第一种方式获取:

1.application.properties文件

server.port=8088
server.servlet.context-path=/springboot-ActiveMQ/
spring.activemq.broker-url=tcp://localhost:61616

#自定义属性
url=http://127.0.0.0:8899

  

2.一个GetPropertiesController测试类

package com.qingfeng.test;

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

@RestController
public class GetPropertiesController {

  @Autowired  
    private Environment environment; 
	
	//http://localhost:8088/springboot-ActiveMQ/getProperties
	@GetMapping("/getProperties")
	public void getProperties() {
	//获取项目端口号server.port=8088
	System.out.println("项目端口号为:"+environment.getProperty("server.port"));
	//获取activemq路径spring.activemq.broker-url=tcp://localhost:61616
	System.out.println("获取activemq路径为:"+environment.getProperty("spring.activemq.broker-url"));
	//获取自定义属性url=http://127.0.0.0:8899
	System.out.println("获取自定义属性路径为:"+environment.getProperty("url"));
	}
	
}

  

3.启动项目访问http://localhost:8088/springboot-ActiveMQ/getProperties可以看到控制台输出

项目端口号为:8088
获取activemq路径为:tcp://localhost:61616

 

第二种方式获取

1.application.properties文件

server.port=8088
server.servlet.context-path=/springboot-ActiveMQ/
spring.activemq.broker-url=tcp://localhost:61616

#自定义属性
url=http://127.0.0.0:8899

  

2.Test测试类

package com.qingfeng.test;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.PropertySource;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@PropertySource("classpath:application.properties")//读取application.properties文件
public class Test {
	
  //获取项目端口号server.port=8088
  @Value("${server.port}")  
    private String servePrort;  
	
  //获取activemq路径spring.activemq.broker-url=tcp://localhost:61616
  @Value("${spring.activemq.broker-url}")  
    private String activemqUrl;  
	
  //获取自定义属性
  @Value("${url}") private String url; @GetMapping("/get") public void get() { //获取项目端口号server.port=8088 System.out.println("项目端口号为:"+servePrort); //获取activemq路径spring.activemq.broker-url=tcp://localhost:61616 System.out.println("获取activemq路径为:"+activemqUrl); //获取自定义属性url=http://127.0.0.0:8899 System.out.println("获取自定义属性路径为:"+url); } }

  

3.启动项目访问http://localhost:8088/springboot-ActiveMQ/getProperties可以看到控制台输出

项目端口号为:8088
获取activemq路径为:tcp://localhost:61616
获取自定义属性路径为:http://127.0.0.0:8899
