java - 休息网络服务

标签 java web-services rest jboss7.x soap-client

我正在我的项目中新开发一个 Rest Web 服务。但是当我点击 url 时它会抛出错误。下面我提到了我的 web.xml 文件代码以及我收到的错误。 提前致谢。

我已经写在Web.xml文件中

<servlet>
    <servlet-name>jersey-serlvet</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
      <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
      <param-value>true</param-value>
    </init-param>
    <load-on-startup>6</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>jersey-serlvet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>

疑虑: 1 我可以使用哪些 jar 来开发 Rest Web 服务。 2 您能否建议我有关休息服务项目中的配置步骤。

最佳答案

你得到了java.lang.NoClassDefFoundError，因为你的pom中缺少一些依赖项。

尝试将 asm 依赖项添加到您的项目 pom.xml

<dependency>
    <groupId>asm</groupId>
    <artifactId>asm</artifactId>
    <version>3.3.1</version>
</dependency>
