Spring Boot + Jersey发生FileNotFoundException (No such file or directory)

Posted 2020-08-21 vincent_ren

我在使用Spring Boot + Jersey 项目，解决了上一篇随笔中的FileNotFoundException，然后又报了一个FileNotFoundException，不过报错信息不一样了

报错信息如下：

ERROR o.a.c.c.C.[Tomcat].[localhost].[/] - StandardWrapper.Throwable 
org.glassfish.hk2.api.MultiException: A MultiException has 1 exceptions.  They are:
1. org.glassfish.jersey.server.internal.scanning.ResourceFinderException: java.io.FileNotFoundException: /home/vincent/myComponent/spring-boot/yishi-service/target/yishi-service-0.5.0.war!/WEB-INF/classes (No such file or directory)

　　此种问题由于jersey无法通过不解压扫描war包中的包造成的，因为我的ResourceConfig如下：

public class WebApplication extends ResourceConfig {
    public WebApplication() {
        System.out.println("WebApplication init...");

//此处造成
        packages("com.jiajian.yishi.rest");

        property(ServerProperties.TRACING, "ALL");

        // Freemarker
        property(MvcFeature.TEMPLATE_BASE_PATH, "/WEB-INF/fm/");
        register(MvcFeature.class);
        register(FreemarkerMvcFeature.class);
        // PageViewBehavior
        register(PageViewContainerRequestFilter.class);
        register(PageViewContainerResponseFilter.class);
    }
}

目前没有很好的解决方案，

如需使用Jersey可以，通过register(Resource.class) 实现

或者将所以Resource类组成一个单独模块，并通过在启动时unpacked。

                        <groupId>你的Resource的groupId</groupId>
                        <artifactId>你的Resource的artifactId</artifactId>

    </plugins>
