# io.spring.platform和org.springframework.cloud #

主要是用来对项目中引入jar的管理，这样后续引入的jar就不需要引入版本了

<dependencyManagement>
    		<dependencies>
    			<dependency>
    				<groupId>io.spring.platform</groupId>
    				<artifactId>platform-bom</artifactId>
    				<version>Brussels-SR4</version>
    				<type>pom</type>
    				<scope>import</scope>
    			</dependency>
    			<dependency>
    				<groupId>org.springframework.cloud</groupId>
    				<artifactId>spring-cloud-dependencies</artifactId>
    				<version>Dalston.SR2</version>
    				<type>pom</type>
    				<scope>import</scope>
    			</dependency>
    		</dependencies>
    	</dependencyManagement>

但是很多项目会自动引入，所以上面那种方式基本上已经被淘汰了

<parent>
    		<groupId>org.springframework.boot</groupId>
    		<artifactId>spring-boot-starter-parent</artifactId>
    		<version>2.2.2.RELEASE</version>
    		<relativePath/> 
    	</parent>

# <module> #

说明当前的maven项目是以下项目的父模块

<modules>
    		<module>../security-app</module>
    		<module>../security-browser</module>
    		<module>../security-core</module>
    		<module>../security-demo</module>
    	</modules>

# commons #

常用的工具包

<dependency>
    			<groupId>commons-lang</groupId>
    			<artifactId>commons-lang</artifactId>
    		</dependency>
    		<dependency>

# controller层中常用注解 #

## @RequestParam ##

映射请求参数栋java方法的参数

## @PageableDefault ##

指定分页参数默认值

## @PathVariable ##

映射url片段到java方法的参数

//正则表达式，只能接收数字   {id:\\d+}
    @RequestMapping(value = "user/{id:\\d+}")
    	public String test(@PathVariable(name="id") String id){
    		System.out.println(id);
    		return "ok";
    	}

## @JsonView ##

控制json输出内容

public class User {
    	
    	public interface UserSimpleView {};
    	public interface UserDetailView extends UserSimpleView {};
    	
    	private String id;
    	
    	private String username;
    	
    	private String password;
    	
    	private Date birthday;
    
    	@JsonView(UserSimpleView.class)
    	public String getUsername() {
    		return username;
    	}
    
    	public void setUsername(String username) {
    		this.username = username;
    	}
    
    	@JsonView(UserDetailView.class)
    	public String getPassword() {
    		return password;
    	}
    
    	public void setPassword(String password) {
    		this.password = password;
    	}
    
    	@JsonView(UserSimpleView.class)
    	public String getId() {
    		return id;
    	}
    
    	public void setId(String id) {
    		this.id = id;
    	}
    	
    	@JsonView(UserSimpleView.class)
    	public Date getBirthday() {
    		return birthday;
    	}
    
    	public void setBirthday(Date birthday) {
    		this.birthday = birthday;
    	}
    	
    }

当方法上使用了 @JsonView之后，只返回user方法中注解了当前注解的属性

@GetMapping("/{id:\\d+}")
    	@JsonView(User.UserDetailView.class)
    	public User getInfo(@ApiParam("用户id") @PathVariable String id) {
    //		throw new RuntimeException("user not exist");
    		System.out.println("进入getInfo服务");
    		User user = new User();
    		user.setUsername("tom");
    		return user;
    	}

## @RequestBody ##

映射请求体到java 方法的参数，大部分用于处理post请求过来的请求体

@PostMapping
    	public User create(@RequestBody User user) {
    
    		System.out.println(user.getId());
    		System.out.println(user.getUsername());
    		System.out.println(user.getPassword());
    		System.out.println(user.getBirthday());
    
    		user.setId("1");
    		return user;
    	}

# 前后端分离中Date的使用 #

在前后端分离的系统中，前端传给后端的时间为时间戳，后端传回给前端的也是时间戳，因为在前后端的思想中，后端对应着多个前端，对于日期的转换成如果由后台处理，其处理逻辑将非常麻烦。

//传到后台的是时间戳，返回回去的时候不需要做任何修改，又直接返回回去
            @PostMapping
    	public User create(@RequestBody User user) {
    
    		System.out.println(user.getBirthday());
    
    		user.setId("1");
    		return user;
    	}

# 校验注解 #

## @NotBlank和@Valid和BindingResult ##

当数据传入的时候，判断是否为空，两个注解要一起使用，否则不会生效。BindingResult类可以使得即使触发了@Valid也会进入到代码中执行（通过BindingResult获取错误信息），而不是直接给前端返回错误码。

@NotBlank(message = "密码不能为空")
    	private String password;

public User update(@Valid @RequestBody User user, BindingResult errors) {
    
    		System.out.println(user.getId());
    		System.out.println(user.getUsername());
    		System.out.println(user.getPassword());
    		System.out.println(user.getBirthday());
    
    		user.setId("1");
    		return user;
    	}

## 大部分校验注解 ##

   <td>Constraint</td> 
   <td>详细信息</td>

  </tr> 
 </tbody> 
</table>

## 自定义校验注解 ##

创建注解，该注解的处理逻辑主要在 MyConstraintValidator类中，里面的三个元素必须存在，message是出现错误之后返回给前端的信息

@Target({ElementType.METHOD, ElementType.FIELD})
    @Retention(RetentionPolicy.RUNTIME)
    @Constraint(validatedBy = MyConstraintValidator.class)
    public @interface MyConstraint {
    	
    	String message();
    
    	Class<?>[] groups() default { };
    
    	Class<? extends Payload>[] payload() default { };
    
    }

MyConstraintValidator，校验逻辑主要在isvalid方法中

public class MyConstraintValidator implements ConstraintValidator<MyConstraint, Object> {
    
    	@Autowired
    	private HelloService helloService;
    	
    	@Override
    	public void initialize(MyConstraint constraintAnnotation) {
    		System.out.println("my validator init");
    	}
    
    	@Override
    	public boolean isValid(Object value, ConstraintValidatorContext context) {
    		helloService.greeting("tom");
    		System.out.println(value);
    		return true;
    	}
    
    }

# 后端错误请求抛出 #

## 浏览器错误抛出 ##

直接在resources文件夹下创建文件以及页面即可

## ![20200105212728278.png][] ##

## 自定义后端错误返回 ##

创建异常类

public class UserNotExistException extends RuntimeException {
    
    	/**
    	 * 
    	 */
    	private static final long serialVersionUID = -6112780192479692859L;
    	
    	private String id;
    	
    	public UserNotExistException(String id) {
    		super("user not exist");
    		this.id = id;
    	}
    
    	public String getId() {
    		return id;
    	}
    
    	public void setId(String id) {
    		this.id = id;
    	}
    
    }

创建ControllerExceptionHandler类，当controller层返回异常时，自定义返回内容

@ControllerAdvice
    public class ControllerExceptionHandler {
    
    	@ExceptionHandler(UserNotExistException.class)
    	@ResponseBody
    	@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    	public Map<String, Object> handleUserNotExistException(UserNotExistException ex) {
    		Map<String, Object> result = new HashMap<>();
    		result.put("id", ex.getId());
    		result.put("message", ex.getMessage());
    		return result;
    	}
    
    }

# RESTful  API的拦截 #

## 过滤器（Filter） ##

@Component
    public class TimeFilter implements Filter {
    
    	/* (non-Javadoc)
    	 * @see javax.servlet.Filter#destroy()
    	 */
    	@Override
    	public void destroy() {
    		System.out.println("time filter destroy");
    	}
    
    	/* (non-Javadoc)
    	 * @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse, javax.servlet.FilterChain)
    	 */
    	@Override
    	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
    			throws IOException, ServletException {
    		System.out.println("time filter start");
    		long start = new Date().getTime();
    		chain.doFilter(request, response);
    		System.out.println("time filter 耗时:"+ (new Date().getTime() - start));
    		System.out.println("time filter finish");
    	}
    
    	/* (non-Javadoc)
    	 * @see javax.servlet.Filter#init(javax.servlet.FilterConfig)
    	 */
    	@Override
    	public void init(FilterConfig arg0) throws ServletException {
    		System.out.println("time filter init");
    	}
    
    }

### 过滤器实现流程 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3OTA5NTA4_size_16_color_FFFFFF_t_70 1][]

## 添加第三方过滤器 ##

因为第三方过滤器中没有加component注解，所以需要我们写一个配置类来添加

@Configuration
    public class WebConfig{
    	
    	@Bean
    	public FilterRegistrationBean timeFilter() {
    		
    		FilterRegistrationBean registrationBean = new FilterRegistrationBean();
    		
    		TimeFilter timeFilter = new TimeFilter();
    		registrationBean.setFilter(timeFilter);
    		
    		List<String> urls = new ArrayList<>();
    		urls.add("/*");     //拦截所有的请求
    		registrationBean.setUrlPatterns(urls);
    		
    		return registrationBean;
    		
    	}
    
    }

过滤器拦截还是存在很多问题的，只能知道拦截下来的http请求和响应的内容，不知道具体是哪个方法去处理的。这个时候需要后面的拦截器来具体处理。

## 拦截器（Interceptor） ##

@Component
    public class TimeInterceptor implements HandlerInterceptor {
    
    	/* (non-Javadoc)
    	 * @see org.springframework.web.servlet.HandlerInterceptor#preHandle(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, java.lang.Object)
    	 */
    	@Override
    	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
    			throws Exception {
    		System.out.println("preHandle");
    		
    		System.out.println(((HandlerMethod)handler).getBean().getClass().getName());
    		System.out.println(((HandlerMethod)handler).getMethod().getName());
    		
    		request.setAttribute("startTime", new Date().getTime());
    		return true;
    	}
    
    	/* (non-Javadoc)
    	 * @see org.springframework.web.servlet.HandlerInterceptor#postHandle(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, java.lang.Object, org.springframework.web.servlet.ModelAndView)
    	 */
    	@Override
    	public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
    			ModelAndView modelAndView) throws Exception {
    		System.out.println("postHandle");
    		Long start = (Long) request.getAttribute("startTime");
    		System.out.println("time interceptor 耗时:"+ (new Date().getTime() - start));
    
    	}
    
    	/* (non-Javadoc)
    	 * @see org.springframework.web.servlet.HandlerInterceptor#afterCompletion(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, java.lang.Object, java.lang.Exception)
    	 */
    	@Override
    	public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
    			throws Exception {
    		System.out.println("afterCompletion");
    		Long start = (Long) request.getAttribute("startTime");
    		System.out.println("time interceptor 耗时:"+ (new Date().getTime() - start));
    		System.out.println("ex is "+ex);
    
    	}
    
    }

@Configuration
    public class WebConfig extends WebMvcConfigurerAdapter {
    	@SuppressWarnings("unused")
    	@Autowired
    	private TimeInterceptor timeInterceptor;
    	
    	@Override
    	public void addInterceptors(InterceptorRegistry registry) {
    		registry.addInterceptor(timeInterceptor);
    	}
    	
    
    }

### 拦截器实现流程 ###

## 切片(Aspect) ##

切片也就是对spring aop的运用，我们由于拦截器不能指定requestmapping方法，不是非常灵活，而aop的话可以指定方法，并且对方法进行增强。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3OTA5NTA4_size_16_color_FFFFFF_t_70 3][]

@Aspect
    @Component
    public class TimeAspect {
    	
    	@Around("execution(* com.imooc.web.controller.UserController.*(..))")
    	public Object handleControllerMethod(ProceedingJoinPoint pjp) throws Throwable {
    		
    		System.out.println("time aspect start");
    		
    		Object[] args = pjp.getArgs();
    		for (Object arg : args) {
    			System.out.println("arg is "+arg);
    		}
    		//args保持的是存入的参数
    		long start = new Date().getTime();
    		
    		Object object = pjp.proceed();
    		//object是调用方法返回的对象
    		System.out.println("time aspect 耗时:"+ (new Date().getTime() - start));
    		
    		System.out.println("time aspect end");
    		
    		return object;
    	}
    
    }

总结：过滤器无法拿到处理的方法的信息，拦截器无法拿到处理的方法传入的数据，切片可以完成前面两个的不足。

    			}
    		};
                  return result;

    }

## 使用DeferredResult异步处理Rest服务 ##

类似于对于每一个应用创建一个线程，线程1发送处理请求，线程2监听接收请求，消息队列简单来说就是MQ，应用2线程就是具体处理请求的应用。

## 异步处理配置 ##

# swagger自动生成文档 #

这个是后端写好代码之后，给前端的接口文档

添加相关依赖

<dependency>
    			<groupId>io.springfox</groupId>
    			<artifactId>springfox-swagger2</artifactId>
    			<version>2.7.0</version>
    		</dependency>
    		<dependency>
    			<groupId>io.springfox</groupId>
    			<artifactId>springfox-swagger-ui</artifactId>
    			<version>2.7.0</version>
    		</dependency>

添加注解

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3OTA5NTA4_size_16_color_FFFFFF_t_70 8][]

输入（注意大小写）

http://localhost:8081/swagger-ui.html

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3OTA5NTA4_size_16_color_FFFFFF_t_70 9][]

在方法上面添加ApiOperation注解，就会在swagger文档中对调用方法描述

@PostMapping
    	@ApiOperation(value = "创建用户")
    	public User create(@Valid @RequestBody User user) {
    
    		System.out.println(user.getId());
    		System.out.println(user.getUsername());
    		System.out.println(user.getPassword());
    		System.out.println(user.getBirthday());
    
    		user.setId("1");
    		return user;
    	}

也可以在属性上添加ApiModelProperty注解，就会在swagger文档中对属性的描述

@ApiModelProperty(value = "用户名")
    	private String username;

对于传入参数的说明使用ApiParam注解

# 引用properties中的属性 #

## properties中自动注入properties文件中的属性 ##

在resourc文件下创建config.properties

# dcm文件存储路径
    project.dcm_image=/dcm_image
    # 标注等其余文件
    project.other_file=${project.dcm_image}/other_file

## 类属性注入properties文件中的属性 ##

创建config.java类,@Component将Config对象注入到Spring容器中，@PropertySource("classpath:config.properties")表示将config.properties注入容器，@ConfigurationProperties(prefix = "project")将config.properties前缀为project和类的变量一一对应

@Component
    @PropertySource("classpath:config.properties")
    @ConfigurationProperties(prefix = "project")
    @Data
    public class Config {
        private String dcm_image;
        private String other_file;
    }

## 单个属性注入properties文件属性 ##

在properties文件注入后，如果引用单个文件，可以用@\{\}

@Value("${project.dcm_image}")

## 利用ResourceBundle类获取properties中属性 ##

ResourceBundle bundle = ResourceBundle.getBundle("config");
    #config.properties 省略后缀名
    String filePath = bundle.getString("project.dcm_image");

## properties乱码 ##
