SpringBoot读取指定配置文件

通过@PropertySource注解读取指定配置文件 ```java @RestController @RequestMapping @PropertySource(value = "classpath:exception.properties", encoding = "UTF-8") public class TestPropertiesController {

@Autowired
Environment env;

@GetMapping("testEnv")
public String testENV(HttpServletRequest request) {
    String demo_00001 = env.getProperty("DEMO_00001");

    return demo_00001;
}

} ```
