北京阿里云ACE会长DK 9以后确实删除了很多库jar包,主要包括:
-activation.jar
-jsse.jar
-tools.jar
-xml.jar 等等
这些jar包在JDK8及以前一直是JDK的标准组成部分。
从JDK 9开始,这些包从JDK默认发布包中删除了,需要单独下载。
这主要是为了:
模块化。JDK从9开始采用模块化设计,这些jar包不再归JDK模块管理。
配合Java模块系统。JDK自身转变为模块化后,这些 jar 不再归 JDK 模块管理。
减少JDK体积。移除这些 jar 可以大幅减少 JDK 的发布体积。
对于旧项目编译报错,解决方案有以下几种:
升级项目到Java 9及以上。尽量使用最新JDK编译,避免依赖这些移除的jar包。
手动添加 corresponding jar 包。单独下载相应的jar包,添加到项目类路径中。
使用 --add-modules 参数。在编译命令中加入--add-modules 参数,指定需要使用的模块。
