有些同学可能需要从 application.properties 配置文件中读取自定义配置，可使用如下方法获取
配置文件内容
hello.world = hi spring boot!
java 代码如下
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class SampleController {
@Autowired
private Environment environment;
@RequestMapping(value = "/say", produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
public String say() {
String msg = environment.getProperty("hello.world");
return msg;
}
}
