Java Fat Jar上的Apache骆驼计时器空指针异常
我正试图在Gradle项目中使用Camel 3.5实现一个计时器,下一个是OpenJDK8Java Fat Jar上的Apache骆驼计时器空指针异常,java,gradle,timer,apache-camel,Java,Gradle,Timer,Apache Camel,我正试图在Gradle项目中使用Camel 3.5实现一个计时器,下一个是OpenJDK8 from("timer://watchexpiration?fixedRate=true&period=600000&delay=0")... 但是,在使用/gradlew build构建胖jar并作为java-jar build/libs/app.jar运行之后 java -jar build/libs/app-all.jar 我在控制台收到下一个错误
from("timer://watchexpiration?fixedRate=true&period=600000&delay=0")...
但是,在使用/gradlew build
构建胖jar并作为java-jar build/libs/app.jar运行之后
java -jar build/libs/app-all.jar
我在控制台收到下一个错误
Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to resolve endpoint: timer://watchexpiration?delay=0&fixedRate=true&period=600000 due to: Error binding property (delay=0) with name: delay on bean: timer://watchexpiration?delay=0&fixedRate=true&period=600000 with value: 0

但是,如果我使用/gradlew run
运行,那么就像我预期的那样运行良好。
我不想在这个项目中使用任何框架。我觉得这只是一个配置问题,或者我的配置有问题
我怎样才能修好它

隐藏jar可能很棘手,因为您需要处理重复的条目。在ApacheCamel中有许多META-INF
服务文件,这些文件正被您简单的jar
方法覆盖。使用它可以自定义合并过程
plugins {
id 'java'
id 'application'
id 'com.github.sherter.google-java-format' version '0.8'
id "com.github.johnrengelman.shadow" version "6.0.0" // Added plugin
}
repositories {
jcenter()
}
dependencies {
// ...
}
application {
mainClassName = 'com.eip.App'
}
// Removed jar step
test {
useJUnitPlatform()
}
googleJavaFormat {
exclude '**/App.java'
}
// Added shadow plugin configuration
shadowJar {
mergeServiceFiles() // Tell plugin to merge duplicate service files
manifest {
attributes 'Main-Class': 'com.eip.App'
}
}
apply plugin: 'com.github.johnrengelman.shadow'
着色的可执行jar将具有后缀-all.jar
java -jar build/libs/app-all.jar
谢谢你的快速回答。对不起,给你一张吉拉的票。很好!再次感谢!
