异常This application has no explicit mapping for /error

Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback. 出现这个异常说明了跳转页面的url无对应的值. 原因1: Application 启动类的位置不对.要将Application类放在最外侧,即包含所有子包 原因:spring-boot会自动加载启动类所在包下及其子包下的所有组件. 原因2: 在springboot的配置文件:application.yml或application.properties中关于视图解析器的配置问题: 当pom文件下的spring-boot-starter-paren版本高时使用: spring.mvc.view.prefix/spring.mvc.view.suffix 当pom文件下的spring-boot-starter-paren版本低时使用: spring.view.prefix/spring.view.suffix 原因3: 控制器的URL路径书写问题 @RequestMapping(“xxxxxxxxxxxxxx”) 实际访问的路径与”xxx”不符合. 转自:https://www.cnblogs.com/lilinzhiyu/p/7921890.html

IDEA开发spring boot应用时 application.yml 或 application.properties 自定义属性提示

大城市里の小女人 提交于 2020-01-05 09:05:24
/*--> */ /*--> */ 在使用spring boot开发过程中,经常会定义一些应用自己的属性,直接写到application配置文件中使用@Value注解进行使用,这样使用也没有什么问题。不过我认为更优雅的方式是定义自己的属性类统一管理,这样在idea中,既能自动提示,又能对配置进行分类管理,显得有条不紊,下面是具体的配置步骤。 第一步:添加依赖(分为maven和gradle两种方式) 1.1 如果你使用的是maven 增加依赖 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> </dependency> 1.2 如果你使用的是gradle 增加依赖并且配置annotationProcessor compileOnly 'org.springframework.boot:spring-boot-configuration-processor' annotationProcessor ‘org.springframework.boot:spring-boot-configuration-processor’ 第二步:创建配置属性类 @Data

Google BigQuery SQL: Prevent column prefix renaming after join

浪尽此生 提交于 2020-01-04 01:57:26
问题 Say you have a table "table_with_100_columns." And you want to add one more column with a simple join... without changing all of the column names. In other words, you wish to write something like SELECT a.* as <a's columns without prefix>, additional_field FROM [table_with_100_columns] a JOIN [table_with_2_columns] b ON a.col1 = b.key You should be able to do this to generate a new table with 101 columns, without having to rename every single column by hand. Right now the only way I know how

问题 http://getbootstrap.com/customize/ Above link, customizes Bootstrap's components, Less variables, and jQuery plugins to get your very own version. I am wondering if it's possible to customize bootstrap by adding prefixes to it's classes, for example: ".container" = ".myid_container" ".btn-group" = ".myid_btn-group" 回答1: You can @extend bootstrap classes and call them whatever you want if you are using sass.

luarocks在macOS系统上的安装

luarocks是基于lua开发的一个包管理工具,所以在安装luarocks之前需要先安装lua(见博客同目录下“lua在MacOS系统上的安装”)。具体的安装步骤如下: 1.源码安装部署luarocks 其实除了源码安装,我们还有其他可以选择的安装方法,比如brew,apt-get,yum等,这里选择源码安装: $ wget http://luarocks.org/releases/luarocks-2.2.2.tar.gz $ tar zxvf luarocks-2.2.2.tar.gz $ cd luarocks-2.2.2 $ ./configure sudo make bootstrap$ sudo luarocks install luasocket$ lua> require "socket" 注:上面的命令是官网的文档里的,与百度到的博客不一致。经实际操作,官网上的可以完美安装,现有博客上的不行。 输出的结果如下: zfydeMacBook-Pro:luarocks-2.2.2 zfy$ ./configure --help Configure LuaRocks. --help This help. --prefix=DIR Prefix where LuaRocks should be installed. Default is /usr/local -

Good Infix to Prefix implementation in Python that covers more operators (e.g. <, <=, etc) of a C program?

别来无恙 提交于 2020-01-01 19:04:13
问题 I have been looking without much luck for an implementation of Python that converts infix to prefix that ranges on a sufficient amount of arithmetic and logic operators and care about its properties on a good python implementation. More specifically I am interested on the operators that would appear on a conditional clause of a C program . (e.g. it would transform a > 0 && b > 1 in prefix. Since I am still newbie to Python I would appreciate if anyone could offer me the implementation or some

如何用wget指定位置?

我需要将文件下载到/ tmp / cron_test /。 我的 wget 代码是 wget --random-wait -r -p -nd -e robots=off -A".pdf" -U mozilla http://math.stanford.edu/undergrad/ 那么是否有一些参数来指定目录? #1楼 从手册页: -P prefix --directory-prefix=prefix Set directory prefix to prefix. The directory prefix is the directory where all other files and sub-directories will be saved to, i.e. the top of the retrieval tree. The default is . (the current directory). 因此,您需要在命令中添加 -P /tmp/cron_test/ (简短格式)或 --directory-prefix=/tmp/cron_test/ (长格式)。 另请注意,如果目录不存在,则会创建该目录。 #2楼 试试这个方法 - import os path = raw_input("enter the url:") fold = raw_input("enter the

xml signature DS prefix?

寵の児 提交于 2020-01-01 09:43:29
问题 Is there a way to sign an XML file with RSA and to have the namespace prefix "ds:Signature" instead of "Signature"? I spent many hourstrying to solve this and from what I can see there is no solution. It seems that it is hard-coded in the class System.Security.Cryptography.Xml.Signature. XmlElement element = document.CreateElement("Signature", "http://www.w3.org/2000/09/xmldsig#"); If anyone knows a solution, I need to sign it like that cause the software importing it verifies it with "ds

jQuery serialize

jQuery serialize模块是对象数组序列化模块。 首先我们先看一下《JavaScript高级程序设计》中的序列化函数,专门用于form参数序列化的。 serialize函数 function serialize(form){ var parts = [], field = null, i, len, j, optLen, option, optValue; for(i = 0, len = form.elements.length; i < len; i++){ field = form.elements[i]; switch(field.type){ case "select-one": case "select-multiple": if(field.name.length){ for(j = 0, optLen = field.options.length; j < optLen; j++){ option= field.options[j]; if(option.selected){ optValue = ""; if(option.hasAttribute){ optValue = (option.hasAttribute("value")) ? option.value : ooption.text); }else{ optValue = (option

关于thrift的介绍:http://www.ibm.com/developerworks/cn/java/j-lo-apachethrift/ Apache Thrift 是 Facebook 实现的一种高效的、支持多种编程语言的远程服务调用的框架。它采用接口描述语言定义并创建服务,支持可扩展的跨语言服务开发,所包含的代码生成引擎可以在多种语言中,如 C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, Smalltalk 等创建高效的、无缝的服务,其传输数据采用二进制格式,相对 XML 和 JSON 体积更小,对于高并发、大数据量和多语言的环境更有优势。本文将详细介绍 Thrift 的使用,并且提供丰富的实例代码加以解释说明,帮助使用者快速构建服务。   好了。身为一个死运维,开发提出需求让装一个这样开发框架,期间提示缺少各种openssl的安装包的库文件依赖。随着安装成功现总结安装过程如下: 安装软件准备:   thrift http://mirror.bit.edu.cn/apache/thrift/0.9.1/thrift-0.9.1.tar.gz   boost http://sourceforge.net/projects/boost/files/boost/1.54.0/boost_1_54
