全局设置

server:
  port: 8081
  servlet:
    context-path: /luckymoney

引用值①

minMoney: 1
maxMoney: 999

@Value("${minMoney}")
private BigDecimal minMoney;

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

引用值②

对象配置
重点：@Component、@ConfigurationProperties

limit:
  minMoney: 1
  maxMoney: 999
  description: 最少要发${limit.minMoney}元，最多能发${limit.maxMoney}元

@Component
@ConfigurationProperties(prefix = "limit")
public class LimitConfig {

    private BigDecimal minMoney;
    private BigDecimal maxMoney;
    private String description;

    getter()/setter()...
}

  @Autowired
    private LimitConfig LimitConfig;

    @GetMapping("/hello")
    public String say(){
        return "说明" + LimitConfig.getDescription();
    }

开发生产分离

新建两个yml，分别为application-dev.yml（开发）,application-prod.yml（生产），通过修改application.yml的spring.prfiles.active指定dev/prod

spring:
  profiles:
    active: prod

Controller相关注解

• @Controller 处理http请求，单独的@Controller需要模板，引入thymeleaf依赖
• @RestController spring4注解，等同于@ResponseBody+@Controller返回Json
• @RequestMapping springboot1.0配置url路径，springboot2.0有@GetMapping...

路径信息获得

@RequestParam("") 获取？后面的值，名称需要匹配
@PathValue("") 获取/后面的值
