Saving a custom Response using the Cache Storage API

阅读更多关于 Saving a custom Response using the Cache Storage API

问题 I'm using Cache Storage to build an progressive web app ( PWA ). There is a custom object that I need to put into my cache, but the cache accepts Response objects as an argument. So my question is how to properly create Response object, that has the JSON in it. I know I can use other caching strategies ( localStorage or IndexedDB ) but I'm particularly curious about this case - saving custom JSON in cache as a request. var myJSON = JSON.stringify({custom:"object"}); caches.open('cache-name')

问题 I'm coming across an issue where I can't seem to set the headers for a fetch request and I think I'm missing something var init = { method: 'GET', headers: { 'Accept': 'application/json', 'Content-Type': 'application/json', 'Authorization': 'Bearer myKey' } }; return fetch(url, init).then(function(response){... When the request is inspected in the network tab, I'm not seeing the headers get set and instead see Access-Control-Request-Headers:accept, authorization, content-type when I would

How to left join fetch multiple children in Hibernate?

阅读更多关于 How to left join fetch multiple children in Hibernate?

问题 I'm working with hibernate and I'm having troubles creating an hql query that fetches all the children of my object. For example: The Object User has a list of Cars and a list of Friends. To get a user with his cars I would use following query: from User u left join fetch u.cars where u.id = ? This works fine, so I thought it would be easy to get a user with his cars and with his friends with following query: from User u left join fetch u.cars left join fetch u.friends where u.id = ? But this

问题 I am trying to query a quote API for a freeCodeCamp project I'm updating to React.js. I am now trying to use Fetch or Axios to query the API but it's caching the response in the browser. I know in $ajax there is a { cache: false } that would force the browser to do a new request. Is there some way I will be able to do the same with Fetch or Axios ? The cache-control setting seems to be already set to max-age: 0 by Axios . This is my code I have that is querying the API. generateQuote = () =>

阅读更多关于超详细 Spring @RequestMapping 注解使用技巧

@RequestMapping 是 Spring Web 应用程序中最常被用到的注解之一。这个注解会将 HTTP 请求映射到 MVC 和 REST 控制器的处理方法上。在这篇文章中，你将会看到 @RequestMapping 注解在被用来进行 Spring MVC 控制器方法的映射可以如何发挥其多才多艺的功能的。 Request Mapping 基础用法在 Spring MVC 应用程序中，RequestDispatcher (在 Front Controller 之下) 这个 servlet 负责将进入的 HTTP 请求路由到控制器的处理方法。在对 Spring MVC 进行的配置的时候, 你需要指定请求与处理方法之间的映射关系。要配置 Web 请求的映射，就需要你用上 @RequestMapping 注解。 @RequestMapping 注解可以在控制器类的级别和/或其中的方法的级别上使用。在类的级别上的注解会将一个特定请求或者请求模式映射到一个控制器之上。之后你还可以另外添加方法级别的注解来进一步指定到处理方法的映射关系。下面是一个同时在类和方法上应用了 @RequestMapping 注解的示例：代码 @RestController @RequestMapping( "/home") public class IndexController {

1.目标：建立“部门”和“员工”之间的单向多对一关联关系。多：员工一：部门 2.创建持久化类 3.希望Hibernate映射自动生成的数据库表 4.配置hbm文件 ①使用插件生成hbm文件 ②Department这一端进行普通的单表映射即可 ③Employee这一端使用many-to-one标签关联Department      < many-to-one name = "department" class = "Department" fetch = "join" column = "DEPT_FK" /> 5.延迟加载 ①默认情况下，加载一个Employee对象到内存中，并不会立即去查询关联的Department对象。 ②设置为立即加载 < many-to-one lazy = "false" 发送两条SQL语句，先查Employee，然后立即查询Department ③设置迫切左外连接 < many-to-one .
