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.

Eclipse用tomcat插件运行项目报错求助!!!
Eclipse用tomcat插件运行项目报:Dmaven.multiModuleProjectDirectory system property is not set. Check $M2_HOME environment variable and mvn script match.然后我按照网上的"可以设一个环境变量M2_HOME指向你的maven安装目录 M2_HOME=D:\Apps\apache-maven-3.3.1 然后在Window->Preference->Java->Installed JREs->Edit 在Default VM arguments中设置 -Dmaven.multiModuleProjectDirectory=$M2_HOME"这个方法去做! 完成这些步骤后去运行就会报:����: �Ҳ������޷��������� Dmaven.multiModuleProjectDirectory=$M2_HOME这个uanma错误!!!!!!!该怎么解决
spring过滤器 jetty插件启动项目报错,用tomcat启动不会报错,怎么回事啊?

springMVC+maven,启动报报JNDI的错误,但我没有用到JNDI

使用jenkins进行自动化部署到tomcat deploy-to 插件,未打印任务后续操作日志?
![图片说明](https://img-ask.csdn.net/upload/201901/03/1546503413_43859.png)我已经配置了构建后操作,但问题是我的日志? ![图片说明](https://img-ask.csdn.net/upload/201901/03/1546503524_603795.png) 直接就没有任何构建后操作,然后就结束了...这是什么情况?没搞明白。 插件是deploy-to tomcat 是8 有配置7 和8都不行。 现在我感觉就是插件有问题,因为构建后操作都未打印,如果有报错这个还好说,哪里配置出错,先行就是直接提示成功,但未做我想要做的事情。求jenkins高手指点一下。
Springboot启动报错 一个是找不到url 一个是找不到dao
## 之前一直启动都没有问题,今天突然发现启动不了 ![图片说明](https://img-ask.csdn.net/upload/201910/10/1570671612_490949.jpg) ## 然后我把启动的位置改成@SpringBootApplication(exclude = DataSourceAutoConfiguration.class) ``` package com.mall.shopping.demo; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration; /*@SpringBootApplication*/ @SpringBootApplication(exclude = DataSourceAutoConfiguration.class) public class DemoApplication {

Python爬虫精简步骤1 获取数据
爬虫的工作分为四步: 1.获取数据。爬虫程序会根据我们提供的网址,向服务器发起请求,然后返回数据。 2.解析数据。爬虫程序会把服务器返回的数据解析成我们能读懂的格式。 3.提取数据。爬虫程序再从中提取出我们需要的数据。 4.储存数据。爬虫程序把这些有用的数据保存起来,便于你日后的使用和分析。 这一篇的内容就是:获取数据。 首先,我们将会利用一个强大的库——requests来获取数据。 在电脑上安装
