Android应用启动过程

没办法，毕竟我又不会，而且在开发应用层的时候也没怎么接触过。但是这东西内容太多了，如果我不写点东西的话长时间不接触肯定会忘记，所以决定一面探究这个过程一面写下这篇文章。

AliOS Things 是 AliOS 家族旗下的、面向 IoT 领域的、轻量级物联网嵌入式操作系统。文本旨在给大家示范一下其中的lorawanapp的示例，完成一个LoRaWAN网络的构建和数据传输，并通过该示例让大家对AliOS Things有一个初步的了解。系统框架图：如下分别介绍了基于VSC, IAR, Keil三个Toolchain的工程示例：基于VSC 基于IAR 基于Keil 不同Toolchain下代码大小比较 Compiler Flash(KB) RAM(KB) Optimization Level gcc 61.26 6.67 -Os iccarm(IAR) 43.83 6.18 -O3 armcc(Keil) 42.64 6.20 -O3 *因为LoRaWAN协议栈内有浮点运算，而大部分跑LoRaWAN的mcu均不含硬件浮点能力，所以需要软件实现

java之mapstruct的应用

一、MapStruct是一个代码生成器，简化了不同的Java Bean之间映射的处理，所以映射指的就是从一个实体变化成一个实体。例如我们在实际开发中，DAO层的实体和一些数据传输对象(DTO)，大部分属性都是相同的，只有少部分的不同，通过mapStruct，可以让不同实体之间的转换变的简单。我们只需要按照约定的方式进行配置即可。 MapStruct是一个可以处理注解的Java编译器插件，可以在命令行中使用，也可以在IDE中使用。MapStruct有一些默认配置，但是也为用户提供了自己进行配置的途径。缺点就是这玩意在使用工具自带的编译器是，不会生成实现类，需要通过maven的方式来进行编辑，才会生成实现类，总体上面来说还是很好用的。相对于BeanUtil等，简介性还是很明显的。目前MapStruct的版本基本都是固定了，可以自己尝试着弄一下。官方api文档地址：http://mapstruct.org/documentation/stable/reference/html/ 二、用到MapStruct需要一个依赖包和一个插件（pom.xml的官方配置） <dependencies> <dependency> <groupId>org.mapstruct</groupId> <artifactId>mapstruct</artifactId> <version>1.2.0.Final</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.7.0</version> <configuration> <source>1.8</source>  <target>1.8</target>  <annotationProcessorPaths> <path> <groupId>org.mapstruct</groupId> <artifactId>mapstruct-processor</artifactId> <version>1.2.0.Final</version> </path> </annotationProcessorPaths> </configuration> </plugin> </plugins> </build> 三、我这里谢了一个简单的例子供参考 package com.troy.jpa.service.mapper; import com.troy.jpa.dto.UserDTO; import com.troy.jpa.entity.User; import com.troy.jpa.service.util.AgeUtil; import org.mapstruct.InheritConfiguration; import org.mapstruct.Mapper; import org.mapstruct.Mapping; import org.mapstruct.Mappings; import java.util.List; @Mapper(componentModel = "spring", uses = {AgeUtil.class}) public interface UserMapper { @Mappings({ @Mapping(source = "age", target = "age", qualifiedByName = {"AgeUtil", "ageAdd"}), }) UserDTO userToDTO(User user); @InheritConfiguration User DTOToUser(UserDTO userDTO); List<UserDTO> userListToDTOList(List<User> users); } package com.troy.jpa.service.util; import org.springframework.stereotype.Component; import javax.script.ScriptEngine; import javax.script.ScriptEngineManager; import javax.script.ScriptException; @Component public class AgeUtil { public String ageAdd(String age) throws ScriptException { ScriptEngineManager engineManager = new ScriptEngineManager(); ScriptEngine engine = engineManager.getEngineByName("JavaScript"); Object eval = engine.eval(age + "+1"); return eval.toString(); } } 说明： 1）在接口上面加入@Mapper，就可以实现实体和DTO之间的装换 2）componentModel 是加入模块，一般都是spring容器，在实现类中会加入@Component注解 3）uses引入外部类，用于实体和DTO之间的工具类 4）多个@Mapping在@Mappings里面编写，也可以单个编写@Mapping。如果实体和DTO之间数据字段一样，可以不加任何注解 5）qualifiedByName 的用法，主要是用来转换特殊数据处理的自定义方式。{}中第一个代表bean，第二种达标方法。 6）@InheritConfiguration 的用法，也就是反向映射。当source，target字段不一样，写第一个。其它的映射可以不用再写@Mapping，直接加入@InheritConfiguration注解即可 7）@Mapping 中的ignore 赋值 true可以忽略某个字段（这个主要是在字段相同，但是类型不同，并且不能装换的时候用）四、当然我这里主要是写的几种常用的用法，mapstruct中还有其他的写法，和api我这里不一一介绍。我提到的主要是比较常用的写法，其他很多方式。可能会用到。但是可以作为自己学习的开始。

[IOS]地图的简单应用

IOSMapKit如何快速入门？下面我来写一个简单的Demo，做简要介绍。效果图：操作步骤： 1.首先创建一个项目，在xib的view中添加一个MapVIew控件，并且导入MapKit.framework和CoreLocation.frameword框架。 2.实现ViewController的代码： ViewController.h: #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #import <CoreLocation/CoreLocation.h> @interface DXWViewController : UIViewController<CLLocationManagerDelegate> @property (retain, nonatomic) IBOutlet MKMapView *mapview; @property(retain,nonatomic)CLLocationManager *manager; @property(retain,nonatomic)CLLocation *location; @property (retain, nonatomic) IBOutletCollection(UILabel) NSArray *labels; @end ViewController.m: #import "DXWViewController.h" #import "Place.h" @interface DXWViewController () @end @implementation DXWViewController - (void)viewDidLoad { [super viewDidLoad]; self.manager = [[CLLocationManager alloc] init]; self.manager.delegate = self; //精度 self.manager.desiredAccuracy = kCLLocationAccuracyBest; [self.manager startUpdatingLocation]; self.mapview.showsUserLocation = YES; } -(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations { self.location = [locations objectAtIndex:0]; [self.labels[0] setText:[NSString stringWithFormat:@"%f\u00B0",self.location.coordinate.longitude]]; [self.labels[1] setText:[NSString stringWithFormat:@"%f\u00B0",self.location.coordinate.longitude]]; [self.labels[2] setText:[NSString stringWithFormat:@"%gm",self.location.horizontalAccuracy]]; [self.labels[3] setText:[NSString stringWithFormat:@"%gm",self.location.altitude]]; [self.labels[4] setText:[NSString stringWithFormat:@"%gm",self.location.verticalAccuracy]]; Place *place = [[Place alloc] init]; place.coordinate = self.location.coordinate; place.title = @"Title"; place.subtitle = @"subTitle"; [self.mapview addAnnotation:place]; //设置精度范围 MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(place.coordinate, 1000, 1000); [self.mapview setRegion:region animated:YES]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)dealloc { [_mapview release]; [_labels release]; [super dealloc]; } @end 3.创建大头针的类： Place.h: #import <Foundation/Foundation.h> #import <MapKit/MapKit.h> @interface Place : NSObject<MKAnnotation> @property(copy,nonatomic)NSString *title; @property(copy,nonatomic)NSString *subtitle; @property(assign,nonatomic)CLLocationCoordinate2D coordinate; @end 本文转蓬莱仙羽51CTO博客，原文链接：http://blog.51cto.com/dingxiaowei/1366415 ，如需转载请自行联系原作者
