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
