配置文件读取

		Properties prop=new Properties();
		InputStream in= new FileInputStream(TestProperties.class.getResource("/").getPath() + "/file/test.properties");
		BufferedReader buffer = new BufferedReader(new InputStreamReader(in, "utf-8"));
		prop.load(buffer);
		System.out.println(prop.getProperty("ip"));

　　

注入方式读取:

1.新建配置文件resource.properties,添加内容server_url=http://192.168.0.158/

2.在spring配置文件中加载<context:property-placeholder location="classpath:conf/resource.properties" />

3.在controller中取值

@Value("${server_url}")
private String server_url;
