spring boot 读取配置文件

闲话少说 上来就是干

首先 弄个 Config 用于加载 自定义的配置文件'

@Configuration
@PropertySource(value = {"classpath:/mypro/dev.properties"},
        ignoreResourceNotFound = true,encoding = "utf-8")
public class Proconfig {

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }
}

测试

@RestController
public class DemoController {

    @Autowired
    Environment env;
    @GetMapping("test2")
    public Map test2(){
        //@PathVariable(value="id") String id
        Map  response= new HashMap<>();

        response.put("id",2);
        response.put("code",800);
        response.put("msg","成功");
        response.put("a",env.getProperty("a"));
        response.put("b",env.getProperty("b"));
        response.put("c",env.getProperty("c"));
        response.put("mybatis.config-locations",env.getProperty("mybatis.config-locations"));
        return response;
    }
}

方式一 注入 Environment 用 getProperty("") 方法 去获取配置参数
