注解:@PropertySource 读取 properties

注解获取properties中参数,代码如下:

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
 * @ClassName propertysource
 * @Date 2020/1/3 17:04
 **/
@Controller
@RequestMapping("/PropertySources")
@PropertySource({"classpath:login.properties"})
public class PropertySources {
    @Value("${login.failCount}")
    private String failCountString;//失败次数

    @RequestMapping(value = "/Login" , produces = "application/json;charset=utf-8")
    private void Login() {
        System.out.println(failCountString);
    }
}

  login.properties

login.failCount=3

运行PropertySources/Login

不想采用注解方式:参考:https://blog.csdn.net/qq_41712834/article/details/103005384
