编译环境和打包环境的问题、logback打印两次的问题、Jersey入参和出参
今日遇到一个十分棘手的问题：在eclipse中编译没问题，但是gradle打包却通不过，经过同事的提醒才知道可能是环境的不同导致的。然后去检查才发现：eclipse使用的是JRE的lib，但是gradle的设置却用的是JDK-HOME的，但是JDK-HOME没有rt.jar，导致打包失败。
将JRE的lib/rt.jar拷贝过去即可。
另外一种gradle失败的情况是找不到中央库
Cannot resolve external dependency mysql:mysql-connector-java:5.1.38 because no
repositories are defined.
Required by:
:dzg-server-api:3.2.1
加上或者其他的即可
repositories {
jcenter()
}
logback打印两次的问题是由于：
Jersey可以通过注册ContainerRequestFilter和ContainerResponseFilter或者VertxRequestProcessor和VertxResponseProcessor来统一获取入参和出参。

使用Professor还可以统计接口返回时间
从gradle 2.12开始，可以使用compileOnly来引入类似servlet-api的jar包，可以达到只编译不引入的目的，类似maven的provided。
