jax-rs - java.lang.ClassNotFoundException：org.glassfish.jersey.servlet.ServletContainer 异常

问题描述

我是 JAX-RS 注释的新手，当我尝试运行它时，我得到了一个错误，比如

java.lang.ClassNotFoundException：org.glassfish.jersey.servlet.ServletContainer，

帮我解决这个问题，我添加了 commons-logging 1.2 jar 和 jersey-bundle 1.18 jar。

解决方案

使用这个 web.xml servlet 指令 - 更改必要的信息：

<servlet> <servlet-name>Jersey REST Service</servlet-name> <!-- Define ServletContainer of Jersey --> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> <!-- Define the package to search for classes --> <init-param> <param-name>com.sun.jersey.config.property.packages</param-name> <param-value>com.javatpoint.rest</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>
