我想我已经遇到了以下问题Jersey doesn’t always work with Spring Boot fat jars.解决方法应该是将POM中的Jersey dependencies设置为requiresUnpack.

我的POM看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                            <artifactId>jersey-container-servlet</artifactId>
                        </dependency>
                        <dependency>

                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

但是当我尝试运行使用mvn包构建的JAR时,仍然会出现以下错误：

2017-01-13 10:44:28.229 ERROR 9289 --- [ost-startStop-1] o.s.b.c.embedded.tomcat.TomcatStarter    : Error starting Tomcat context. Exception: org.springframework.beans.factory.UnsatisfiedDependencyException. Message: Error creating bean with name 'org.springframework.boot.autoconfigure.jersey.JerseyAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jerseyConfig' defined in URL [jar:file:/home/mikael/Dev/Java/Java%20Programs/springBootDemo/target/demo-0.0.1-SNAPSHOT.jar!/BOOT-INF/classes!/net/hagstrom/JerseyConfig.class]: Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [net.hagstrom.JerseyConfig]: Constructor threw exception; nested exception is org.glassfish.jersey.server.internal.scanning.ResourceFinderException: java.io.FileNotFoundException: /home/mikael/Dev/Java/Java Programs/springBootDemo/target/demo-0.0.1-SNAPSHOT.jar!/BOOT-INF/classes (No such file or directory)

运行我在IDE中使用Artifacts构建的JAR工作得很好.

我的POM或我用Maven构建JAR的方式有问题吗？

解决方法:

这可能已经修复了.我发布了几篇与使用Spring Boot,Jersey 2和Docker创建API相关的博客文章,并使用Swagger记录它们：http://tech.asimio.net/2016/04/05/Microservices-using-Spring-Boot-Jersey-Swagger-and-Docker.html和http://tech.asimio.net/2016/05/07/Documenting-multiple-REST-API-versions-using-Spring-Boot-Jersey-and-Swagger.html,两者都附带源代码,我不需要解压缩和重新打包Jersey 2依赖项.

另一方面,当我正在为另一个关于Services Registration and Discovery using Spring Cloud, Eureka, Ribbon and Feign的博客编写附带的源代码时,我正在整合Spring Boot和Jersey 1(Jersey 1没有Spring Boot启动器我记得解决了解决Jersey 1依赖关系的问题需要为该特定API服务创建多模块Maven项目.
