由 随声附和 提交于 2021-02-11 13:48:18
问题 Update: As there is only one answer for now I try to describe it better now. In short words, my test application runs fine in eclipse and when starting with mvn exec but building a running/working executable jar package does not work for this project. Now the longer description. I'm learning Java for about 8 month and use maven to setup build projects and Eclipse as IDE for writing and debugging. Currently I am trying to make some small database projects using Spring, Hibernate and for

How to track login of users in a Java Spring Boot application

由 懵懂的女人 提交于 2021-02-11 13:19:18
问题 The application is already configured via Spring Session to log user sessions into a SQL database. Now I would like to log the user sessions into my own database table for purposes of tracking user login data. What are some possible ways to do so? 回答1: You can create a bean which implements ApplicationListener<> , for either AuthenticationSuccessEvent or InteractiveAuthenticationSuccessEvent events. See for further info: http://www.baeldung.com/spring-events https://docs.spring.io/spring-boot

这个404你能解决吗？

点击上方蓝字关注 👆👆 今天在tomcat里部署运行了一个小工程，工程结构如下： 运行tomcat服务器后，访问index.html，发现报404： 但是后台接口是正常返回的： 去看webapps里工程目录下，index.html文件是有的，见鬼了，是哪儿出了问题？ 然后看到控制台日志（或者tomcat_home/logs/catalina.log）报错如下： org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping fo und for HTTP request with URI [ /artmuseum/i ndex.html] in DispatcherServlet with name 'springmvc' 大致意思是springmvc这个servlet处理不了index.html。原来是配置有问题。 看看web.xml配置，是这样写的： <!-- 注册前端控制器 --> < servlet > < servlet-name > springmvc </ servlet-name > < servlet-class > org.springframework.web.servlet.DispatcherServlet </ servlet-class > < init-param > <

Spring Boot Binder API support for @Value Annotations

由 試著忘記壹切 提交于 2021-02-11 13:12:40
问题 I am using the Spring Boot Binder API in an EnvironmentPostProcessor (i.e. before the actual application context(s) is (are) refreshed) to bind a custom ConfigurationProperty object. I want users to have to specify exactly one mandatory property in application.yml : com.acme.kafka.service-instance-name: <user-provided value> . Given that, I will be able to derive the other (required but not mandatory to be put in by the user) properties: com: acme: kafka: username: <can be fetched from VCAP

java消息队列--ActiveMQ

1、下载安装ActiveMQ 　　ActiveMQ官网下载地址： http://activemq.apache.org/download.html 　　ActiveMQ 提供了Windows 和Linux、Unix 等几个版本，楼主这里选择了Linux 版本下进行开发。 　　下载完安装包，解压之后的目录： 　 　　从它的目录来说，还是很简单的： bin存放的是脚本文件 conf存放的是基本配置文件 data存放的是日志文件 docs存放的是说明文档 examples存放的是简单的实例 lib存放的是activemq所需jar包 webapps用于存放项目的目录 2、启动ActiveMQ　 　　进入到ActiveMQ 安装目录的Bin 目录，linux 下输入 ./activemq start 启动activeMQ 服务。 　　 输入命令之后，会提示我们创建了一个进程IP 号，这时候说明服务已经成功启动了。 　　 　　ActiveMQ默认启动时，启动了内置的jetty服务器，提供一个用于监控ActiveMQ的admin应用。 　　admin： http://127.0.0.1:8161/admin/ 　　我们在浏览器打开链接之后输入账号密码（这里和tomcat 服务器类似） 　　默认账号：admin 　　密码：admin 　　 　　　到这里为止，ActiveMQ 服务端就启动完毕了。
