• 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
