WebSphere Liberty Server（IBM Bluemix） - 在服务器上运行RESTful Web服务时出错

时间：2016-04-21 19:05:36

标签： java maven jax-rs ibm-cloud websphere-liberty

我有一个maven RESTful Web服务应用程序（支持JAX-RS）。当我在Tomcat v7.0服务器上运行它时，我的API工作正常。但是，当我在Bluemix中使用的WebSphere Liberty Server上部署相同项目时出现错误。

部署应用程序时，它会毫无问题地加载。我也可以打开index.jsp页面。它甚至可以完美地运行一些API请求调用（通常是不接受任何输入的请求，不会产生输出。但是，对于某些API请求，它会显示此错误：

我无法弄清楚问题。我在Google中搜索并意识到如果编译时环境与运行时环境不同，可能会发生此问题（VerifyError）。但是，我无法弄明白。

这是我的pom.xml文件：

但是在向API发出请求时我收到此错误。 我的错误在哪里？

In your pom.xml you are referencing the JAX/RS implementation of Glassfish/Jersey. This is no problem in Tomcat, because Tomcat is only a Servlet container, but Liberty is a full JEE application server, that comes with its own JAX/RS implementation based on Apache CXF and Jackson.

So first I would recommend that you install Liberty also locally to test your code before you ship it into Bluemix. Just go to liberty's download page.

Then you should remove all your Glassfish dependencies and change your pom.xml to use the following dependency:

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>7.0</version>
    <scope>provided</scope>
</dependency>

This is plain JEE and has no dependency on any vendor specific code. Look at this simple pom.xml. This would run in Liberty on Bluemix.
