java - 我需要为 JDK 1.9 下载哪个 Jersey 版本？

Question

我正在使用 jdk 1.9。我正在尝试提供一个简单的 ReST 服务。使用 Maven 原型(prototype)创建项目:jersey-quickstart-webapp。然后我继续修改 pom.xml 和 web.xml。我的maven配置如下图所示:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

当我尝试访问这个 URL 时:http://localhost:8080/webapi/myresource - 我看到以下错误:

当我将构建配置从 1.9 更改为 1.8 时

<configuration>
    <source>1.8</source>
    <target>1.8</target>
</configuration>

服务正常运行，我在浏览器上看到了预期的结果。

我正在使用 Intellij，项目 SDK - 9，项目语言级别 - 9

我应该导入哪些 jar 以使其与 1.9 一起使用？或者我是否需要更改 Maven 配置才能使其正常工作？

Answer 1

当前 Jersey 有一个阴影 asm 5 依赖项的问题，它不适用于 Java 9 字节码。看起来 Jersey 1.x 没有被 Java 9 采用，目前还不清楚这种支持是否会到来。作为临时解决方案，我做了一个 branch我删除了阴影 asm，迁移了代码中的包以使用常规 asm 依赖项并将 asm 6.0 放入 maven 依赖项中。

您只能从此分支构建 jersey-server 和 jersey-servlet 模块，因为只有这两个依赖于 asm 并在您的项目中使用这两个自定义工件。

我的项目在这样的替换下运行良好，但我不能保证它是 100% 有效的解决方案，我无法毫无失败地构建整个发行版，也无法投入时间进行全面采用和检查是否正确现在。同时， Jersey 的主要部件制造没有问题。

因此，您的最终 pom 将如下所示:

<!--regular jersey dependencies with the last 1.19.4 version-->
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-server</artifactId>
    <version>${custom-jersey-with-asm6.version}</version>
