Spring boot configuration: how to return always same random value when referenced?

由 余生颓废 提交于 2020-04-11 06:39:10
问题 I have the application property APP_ID that should be randomly generated (UUID) and that should have the same value for the entire Spring Boot application. What I did was the following: I defined in the application.properties file the APP_ID=${random.uuid} . The UUID gets created successfully, however for every property reference @Value("${APP_ID}") I will get a different UUID. Example: In class Foo I want to use the appId : @Value("${APP_ID}") private String appId; In class Bar I want to use

MyBatis连接Oracle数据库的例子

之前我曾写过一篇博客，提及了如何建立一个最简单的MyBatis连接Oracle数据库的Demo。 博客地址如下： http://my.oschina.net/Tsybius2014/blog/626206 在这篇博客中，我使用了XML配置MyBatis连接数据库相关的内容，并通过MyBatis提供的函数，直接通过XML文件配置的内容，通过SqlSessionFactory建立SqlSession。 本文将说明另一种建立SqlSession，还是使用 SqlSessionFactory ，但不通过XML配置文件建立，而是通过代码直接建立。 我的电脑操作系统版本为Win7旗舰版（ServicePack1），Oracle版本为Oracle11g 程序使用的jar包有：mybatis-3.2.2.jar、ojdbc14-10.2.0.2.0.jar 之前有配置文件mybatis-config.xml内容如下： <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <environments default=

NoSuchJobException when running a job programmatically in Spring Batch

由 别说谁变了你拦得住时间么 提交于 2020-04-08 11:35:19
问题 I have a Job running on startup. I want to run this job programmatically at a particular point of my application, not when I start my app. When running on startup I have no problem, but I got a "NoSuchJobException" ( No job configuration with the name [importCityFileJob] was registered ) when I try to run it programmatically. After looking on the web, I think it's a problem related to JobRegistry, but I don't know how to solve it. Note : my whole batch configuration is set programmatically, I

问题 I'm building a single page application which does all of it's html request routing on the client side and on the backend it uses dropwizard to provide a bunch of JSON services. Essentially I'm having trouble getting the jetty in dropwizard to serve index.html for every request except to the following paths: /css /i18n /img /js /lib /services /templates In fact I'm having a lot of trouble finding documentation that tells you how to setup any http routing at all.

How to specify include directory for configure script

由 岁酱吖の 提交于 2020-04-07 14:54:12
问题 I have a linux system at my workplace with pretty old packages and no root access. I'm compiling packages that I need from source with --prefix=[somewhere in homedir] . My problem is that I just can't find out how to convince configure to look for header files in a specific directory. The source is cpp. I tried with environment variables related to g++ and looking up flags and googling but I had no success. Can someone help me solve this? 回答1: The normal way to do this is --with-<feature>=

What is the “source” attribute of the Context element of an Apache Tomcat configuration file for?

由 拟墨画扇 提交于 2020-04-05 19:30:52
问题 It's somehow related to Eclipse. For example: <Host> <Context docBase="foo" path="/foo" reloadable="true" source="org.eclipse.jst.j2ee.server:foo" /> </Host> 回答1: Eclipse WTP adds the source attribute to the project-related <Context> element to identify the location of the source code associated with the context (thus, the actual project in the workspace which has been deployed to this server from inside Eclipse). If you wondered about this due to a warning during Tomcat's startup, since

Action class execution flow in Struts

由 ≯℡__Kan透↙ 提交于 2020-03-27 07:03:40
问题 I was in an impression that execute() method in Struts is the first method called when action class is invoked from struts.xml . But when I debug my code which has a constructor in action class, I see that constructor gets executed first(I am not creating any instance here). 1) Can some please explain the flow of execution in action class, i.e. what methods are called before actually getting to execute. 2) I am not sure why constructor is getting called 回答1: Struts calls a lot of stuff before
