Configure logback in Wildfly

由 余生长醉 提交于 2019-12-23 09:25:22
问题 I have terrible problems to figure out how to configure logging via logback in my Java EE application on Wildfly 10. I tried to put slf4j-api-1.7.21.jar , logback-classic-1.1.7.jar and logback-core-1.1.7.jar in my ear in /lib/ , add logback.xml to resources in my ejb module and add jboss-deployment-structure.xml into my ear META-INF . It almost works... Logback creates my log files and correctly log into them. Unfortunately logging to console works strange. It looks like wildfly concatenated

问题 I created a webapp that runs on Tomcat 8. As always I want to use slf4j and in this case, backed by java.util.logging (because it is the default for Tomcat). The relevant dependencies are this: <!-- logging --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.10</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-jdk14</artifactId> <version>1.7.10</version> <scope>runtime</scope> </dependency> I added some log statements

问题 I'm in the process of switching from Log4j to Logback but I'm not having success at making Logback work yet. I have placed logback.xml in the root directory of my Eclipse Java project and below is its content: <configuration> <appender name="FILE" class="ch.qos.logback.core.FileAppender"> <file>myApp.log</file> <encoder> <pattern>%date %level [%thread] %logger{10} [%file:%line] %msg%n</pattern> </encoder> </appender> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

问题 I have tried to get this working for three days now in my project and created a simple project to test. I searched around very similar issues on here but didn't find anything that helped with how to solve the error I'm getting. I went even as far as reformatting my Fedora 25 as it works on a Windows 10 but still nothing. I have also enabled in both settings and other settings in Intellij-2016.3.4 annotation processing which according to other answers should have fixed it but, it doesn't

问题 Akka and Scala newbie here, please feel free to edit the question as necessary in order to clearly articulate my intent in the domain of Scala and Akka. Before I show code snippets, here's the problem I want to solve: I essentially want to develop a common module for my team to use when they're developing their applications using Akka actors. I want to allow them to mixin a trait which will extend their receive functionality at runtime, mainly for logging purposes. I'm running into compile

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 简介 Feign是一款java的Restful客户端组件，Feign使得 Java HTTP 客户端编写更方便。Feign 灵感来源于Retrofit, JAXRS-2.0和WebSocket。Feign 最初是为了降低统一绑定Denominator 到 HTTP API 的复杂度，不区分是否支持 ReSTfulness。 为什么选择Feign而不是其他 你可以使用 Jersey 和 CXF 这些来写一个 Rest 或 SOAP 服务的java客服端。你也可以直接使用 Apache HttpClient 来实现。但是 Feign 的目的是尽量的减少资源和代码来实现和 HTTP API 的连接。通过自定义的编码解码器以及错误处理，你可以编写任何基于文本的 HTTP API。 Feign工作机制 Feign 通过注解注入一个模板化请求进行工作。只需在发送之前关闭它，参数就可以被直接的运用到模板中。然而这也限制了 Feign，只支持文本形式的API，它在响应请求等方面极大的简化了系统。同时，它也是十分容易进行单元测试的。 基本用法 基本的使用如下所示，一个对于canonical Retrofit sample的适配。 interface GitHub { @RequestLine("GET /repos/{owner
