Question

我正在使用带有jetty-maven-plugin 8.1.2.v20120308的jersey-server 1.12。如果我使用的是jersey-server 1.9版本或者不到一切正常但是jersey-server 1.10及以上会导致问题。我是否缺少任何依赖或在pom或web.xml中添加一些东西

但是当我运行mvn -Djetty.port = 9999 jetty时：运行但是得到错误：

我做了双重检查WEB-INF / lib输出如下：

Miteshs-MacBook-Pro:lib miteshpatel$ pwd 
/Users/miteshpatel/Documents/dev/examples/my-webservices/target/my-webservices/WEB-INF/lib
Miteshs-MacBook-Pro:lib miteshpatel$ ls 
asm-3.1.jar     jersey-core-1.10.jar    jersey-server-1.10.jar  log4j-1.2.13.jar

Answer 1

经过几次搜索，我找到了根本原因。如果你正在使用jersey-server 1.10和/或以上，你需要在pom中添加jersey-servlet作为依赖。

https://blogs.oracle.com/japod/entry/jersey_1_10_is_released

jersey-server-1.12与jetty-maven-plugin不能一起工作
