Vaadin，Jetty，Spring Data，Maven-例外 [英] Vaadin, Jetty, Spring Data, Maven - Exception
问题描述
我正在尝试将Spring Data集成到我们的Vaadin项目中.因此，我尝试运行以下使用相同技术的示例代码:
https://github.com/henrikerola/vaadin-spring-boot-todo
我唯一更改的是我添加了码头，因为我们需要在项目中使用它.
不幸的是，在jetty:run之后，我得到了以下异常:
Exception in thread "main" java.util.ServiceConfigurationError:
org.apache.juli.logging.Log: Provider org.eclipse.jetty.apache.jsp.JuliLog not a subtype
我的pom.xml看起来像这样:
<?xml version="1.0" encoding="UTF-8"?>...

我还没有机会找出造成这种情况的实际原因，但是我怀疑码头与码头之间存在类路径问题. spring-boot首选的tomcat.
- 无论如何，如果您打算进一步使用可能最简单的spring-boot，请
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jetty</artifactId> </dependency>此外，您可能不想运行
mvn jetty-run，而是希望运行demo.DemoApplication，以便它可以正确发现spring配置并初始化上下文.- 如果计划避免使用spring-boot，请删除父定义以及其他启动依赖项和插件.另外，请记住手动设置应用程序以在starup上初始化spring上下文.
I'm trying to integrate Spring Data within our Vaadin project. So I tried running the following sample code which uses the same technologies:
https://github.com/henrikerola/vaadin-spring-boot-todo
The only thing I changed is that I added jetty as we need to use it for our project.
Unfortunately, after
jetty:runI'm getting the following exception:Exception in thread "main" java.util.ServiceConfigurationError: org.apache.juli.logging.Log: Provider org.eclipse.jetty.apache.jsp.JuliLog not a subtypeMy pom.xml looks like this:
<?xml version="1.0" encoding="UTF-8"?>... <modelVersion>4.0.0</modelVersion> <groupId>org.test</groupId> <artifactId>demo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>demo</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.2.3.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <start-class>demo.DemoApplication</start-class> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>com.vaadin</groupId> <artifactId>vaadin-spring-boot-starter</artifactId> <version>1.0.0.beta2</version> </dependency> <dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>com.vaadin</groupId> <artifactId>vaadin-bom</artifactId> <version>7.4.2</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>9.2.10.v20150310</version> </plugin> </plugins> </build>解决方案I haven't had the chance to dig up the actual reason for this, but I suspect a classpath issue between jetty & tomcat which is preferred by spring-boot.
- Anyhow, if you plan on further using spring-boot which is probably easiest, the spring-boot documentation offers an example of replacing tomcat with jetty, and it's simple as adding the following to your pom:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jetty</artifactId> </dependency>Also, instead of running
mvn jetty-runyou'd probably want to run thedemo.DemoApplicationso it can properly discover the spring configuration and initialize the context.- If you plan on avoiding spring-boot, then remove the parent definition as well as the other boot dependencies and plugins. Also, remember to manually setup the application to initialize the spring context on starup.
