springboot 多模块打包war,tomcat启动提示找不到配置文件
新项目使用springboot maven module方式新建了多个子模块,(多个)web,service,dao,entity,util、storage。其中web依赖entity、service、util、storage。 uitl模块中有个ConfigUtil.java @Component @ConfigurationProperties @PropertySource(value = "classpath:config.properties",encoding = "utf-8") public class ConfigUtil { ...... } 其中config.properties文件放在util模块的resources文件夹下。 在将其中一个web项目打包成war时,在tomcat中启动时提示找不到config.properties ![图片说明](https://img-ask.csdn.net/upload/202001/20/1579522003_255875.png) 下面是uitl模块的pom文件 ``` <?xml version="1.0"?> <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.zjyc.dsy</groupId> <artifactId>dsy-al</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <groupId>com.zjyc.dsy.util</groupId> <artifactId>dsy-util</artifactId> <name>dsy-util</name> <packaging>jar</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>artemis</groupId> <artifactId>artemis-lib</artifactId> <version>1.0</version> <scope>system</scope> <systemPath>${project.basedir}/src/main/resources/jar/artemis-http-client-1.0-SNAPSHOT.jar</systemPath> </dependency> </dependencies> <build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> </includes> <!-- resource的filtering属性用来表示资源文件中的占位符是否需要被替换,true为需要替换。 --> <filtering>false</filtering> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*</include> </includes> <filtering>false</filtering> </resource> </resources> </build> </project> ``` 下面是web模块的pom ``` <?xml version="1.0"?> <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <modelVersion>4.0.0</modelVersion> <packaging>war</packaging> <parent> <groupId>com.zjyc.dsy</groupId> <artifactId>dsy-al</artifactId> <version>0.0.1-SNAPSHOT</version> <relativePath>../pom.xml</relativePath> </parent> <groupId>com.zjyc.dsy.web</groupId> <artifactId>dsy-web</artifactId> <name>dsy-web</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>com.zjyc.dsy.entity</groupId> <artifactId>dsy-entity</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <dependency> <groupId>com.zjyc.dsy.service</groupId> <artifactId>dsy-service</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <dependency> <groupId>com.zjyc.dsy.util</groupId> <artifactId>dsy-util</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <dependency> <groupId>com.zjyc.dsy.storage</groupId> <artifactId>dsy-storage</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>4.0.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <!-- 引入java编译器插件 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> <compilerVersion>1.8</compilerVersion> <encoding>UTF-8</encoding> </configuration> </plugin> <!-- 资源文件拷贝插件 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <configuration> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>unpack</id> <phase>generate-resources</phase> <goals> <goal>unpack</goal> </goals> <configuration> <artifactItems> <artifactItem> <groupId>com.zjyc.dsy.util</groupId> <artifactId>dsy-util</artifactId> <version>0.0.1-SNAPSHOT</version> <type>jar</type> <overWrite>true</overWrite> <outputDirectory>${project.build.directory}/classes</outputDirectory> </artifactItem> </artifactItems> </configuration> </execution> </executions> </plugin> </plugins> <pluginManagement> <plugins> <!--This plugin's configuration is used to store Eclipse m2e settings only.

Maven聚合的多模块项目如何做单元测试生成汇总的各模块测试报告?
【需求】Maven聚合的多模块项目如何做单元测试生成汇总的各模块测试报告? 【现状】: 已知有用Mavne中Aggregation管理的多个子项目,创建了顶层POM工程sra_pom,然后创建了两个Maven Module子模块sra_client和sra_sa,从git中拉取代码。 如下 ``` <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.sra.dgm</groupId> <artifactId>sra_pom</artifactId> <version>2.0</version> <packaging>pom</packaging> <modules> <module>sra_client</module> <module>sra_sa</module> </modules> </project> ``` 现需要集成该Maven工程到jenkins上完成编译打包,以及单元测试,要求一个工程完成编译打包及测试,并且生成一份按模块划分的汇总的junit测试报告。(统计代码覆盖率,插件为jacoco,junit) 目前已知, * 直接在顶层pom执行maven clean package可直接打成war包。 问:各模块单独建jenkins工程配置jacoco和junit可生成单元测试报告,但在一个jenkins工程总时,对应的jenkins工程及pom该如何配置呢?

什么情况下一个 .pom文件中会有两套完全一样的配置?
【背景】: 1、已有Maven project 及多模块的子工程。如主工程为sacm(Maven project)的父pom工程,另有两个子模块sac,sam(均为Maven Module) 2、主工程sacm依赖仓库里的另一个父pom工程ss 【问题描述】 1、继承maven工程到jenkins上编译报错 ``` “Non-pareable POM /jenkins/workspace/testDemo/./m2cache/cn/ss/parent/2.1.0-release/ss-parent-2.1.0.pom:processing instruction can not have PITarget with reserved xml name (position:END_TAG seen...<p.rofiles>\r\n<?xml....@55:7).........” ``` 2、根据报错提示查看ss-parent-2.1.0.pom文件(父pom文件),发现有两套完全一样的配置。 如 ``` <?xml version="1.0" encoding="UTF-8"?> <project...> ........ <modelVersion>4.0.0</modelVersion> <groupId>com.ss</groupId> <artifactId>ss</artifactId> <version>2.1.0-RELEASE</version> <packaging>pom</packaging> .......... </project> <?xml version="1.0" encoding="UTF-8"?> <project....> ........ <modelVersion>4.0.0</modelVersion> <groupId>com.ss</groupId> <artifactId>ss</artifactId> <version>2.1.0-RELEASE</version> <packaging>pom</packaging> .......... </project> ``` 3、已知可以找到有配置上述依赖的 ``` <dependency> ``` 【求助】:请教大家什么情况,仓库中的.pom文件会有这样两套完全一样的配置,有没有解决办法呢?谢谢! (问题表述不清晰的地方,请@到我,感谢!)

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过...

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入 假设现有4个人...
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
