问题 I have started using WebClient in my Spring boot project recently. Can somebody throw some light on the differences/usages between exchange and retrieve method in WebClient .

Much Thanks. 回答1: According to spring Webclient api documentation the difference between the two is that exchange retrieve in addition to the body other http response

点击上方 java项目开发 , 选择 设为星标 优质文章,及时送达 -- 来源:zhihu.com/question/294282002/ answer/521229241 问题:Spring MVC 过时了吗? 我看了一下这个问题的日志,这个问题是2018年9月提出来的。 那么好,首先给出结论:Spring MVC没有过时,它仍然是当前主流的Java Web开发框架。但是,在这个时间点谈论这个问题就有点意思了。题主提出这个问题的时候,可能都没有意识到这个问题正处在Web开发思想变革的分水岭上。 首先,说一下答主这个问题描述中不准确的地方,后面再着重说说现在的分水岭。 现在jsp似乎已经渐渐淡出大家的视野。web开发朝着前后端分离的方向去了 这个没错。但是, 像spring mvc这样前后端耦合较大的框架是否过时了? 这个疑问就没有必要了。 Spring MVC前后端耦合不大啊。你完全可以使用@RestController。 @RestControlleris a specialized version of the controller. It includes the @Controller and @ResponseBody annotations and as a result, simplifies the controller implementation:

文章目录 简介 依赖关系 数据库连接配置 数据库初始化 DAO操作 Service操作和Transaction controller 测试 简介 上篇文章我们讲到了怎么在Spring webFlux中使用r2dbc,今天我们看一下怎么使用spring-data-r2dbc这个Spring data对r2dbc的封装来进行r2dbc操作。 依赖关系 要使用Spring-datea-r2dbc需要配置下面的依赖关系: < dependencies > < dependency > < groupId > org.springframework.boot </ groupId > < artifactId > spring-boot-starter-data-r2dbc </ artifactId > < version > 2.3.3.RELEASE </ version > </ dependency > <!-- R2DBC H2 Driver --> < dependency > < groupId > io.r2dbc </ groupId > < artifactId > r2dbc-h2 </ artifactId > < version > ${r2dbc-h2.version} </ version > </ dependency > < dependency > <

关注我 转载请务必注明原创地址为: http://www.54tianzhisheng.cn/2018/04/30/springboot_SpringApplication/ 前言 在 Spring Boot 项目的启动类中常见代码如下: @SpringBootApplication public class SpringbotApplication { public static void main(String[] args) { SpringApplication.run(SpringbotApplication.class, args); } } 其中也就两个比较引人注意的地方: @SpringBootApplication SpringApplication.run() 对于第一个注解 @SpringBootApplication ,我已经在博客 Spring Boot 2.0系列文章(六):Spring Boot 2.0中SpringBootApplication注解详解 中详细的讲解了。接下来就是深入探究第二个了 SpringApplication.run() 。 换个姿势 上面的姿势太简单了,只一行代码就完事了。 SpringApplication.run(SpringbotApplication.class, args); 其实是支持做一些个性化的设置

使用 使用起来应该像是这个样子 wxue(options) setup 配置应该是包含一个 setup 选项是一个函数,返回的函数可以 this.xxx 调用,返回的数据可以 this.data.xxx 用到,如下 import { wxue, reactive } from 'wxue' wxue({ setup(options) { const test = reactive({ x : 1 , y : 2 , }) setInterval( () => { test.x++ }, 1000 ) return { test, } }, }) ref api 应该有如下api reactive ref unref toRef toRefs computed watchEffect watch 各种钩子,与小程序生命周期一致 示例 import { wxue, nextTick, ref, onShow } from 'wxue' function useAutoAdd ( x ) { const b = ref(x) setInterval( () => { b.value++ }, 1000 ) return b } wxue({ data : {}, setup(options) { const b = useAutoAdd( 2 ) onShow( () => {
