我正在使用 jersey 开发应用程序，但收到 404 未找到异常
这是 web.xml

我想使用 jersey pojo 支持，以便我的 webservice 状态类将转换为 json，并且 json 将转换为 CalculatorModal

没有异常(exception)。为什么显示未找到错误是什么？？
最佳答案
我发现问题是因为:我的 web.xml 中有两个初始化参数
a) Application
b) package path
我相信应用程序映射会覆盖包参数映射，然后在我的应用程序类中我必须显式注册我的资源类。
我希望这一点很清楚。
关于java - Jersey 应用程序 404 未找到错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23173816/
