java - 异步调度程序错误

Question

当我尝试完全根据此处显示的示例上传文件时出现错误 Sample

错误是

Allocate exception for servlet com.testapp.rest.JaxRsActivator: java.lang.RuntimeException: Unable to find a public constructor for class org.jboss.resteasy.core.AsynchronousDispatcher

这意味着什么？

Answer 1

如果部署到 JBoss 7.x，您需要将 resteasy 依赖项的范围更改为 provided。这是因为那些特定的库已经作为模块包含在 JBoss 中:

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxrs</artifactId>
    <version>2.2.1.GA</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-multipart-provider</artifactId>
    <version>2.2.0.GA</version>
    <scope>provided</scope>
</dependency>
