@wendal

网上说 手动 改 内存， 尽量用公共jar，，，都不行啊！ 这是我应用出现 内存一直耗着?@wendal

@wendal 已经设置为这样了
set JAVA_OPTS="-server -Xms1024m -Xmx1024m -XX:PermSize=256M -XX:MaxNewSize=512m -XX:MaxPermSize=512m -Djava.awt.headless=true -Ddruid.registerToSysProperty=true"

@wendal 怎么看出来的，，？ 4个 应用， 他们有共同的jar 每个有 35个 其中 28个左右是 相同的！

我的 应用都是 在jdk7上开发的， 直接把服务器的换成8 不会有影响吧?
服务器是windows的 一个4g内存。
这些共同的jar有必要 公用起来吗？ 那么打包war的时候 ftp上传到服务器，还得把lib的jar删除？@wendal

换成 jdk8+tomcat8
出现

@wendal 打包了， 没有修改war内容，仅仅是换成 jdk8 tomcat也从7 改为8

@wendal war包里面 \WEB-INF\classes\custom 有我的配置文件的 但是 服务器提示

@wendal 尝试了好多次 unpackWARs="false" autoDeploy="true" tomcat 也设置成这样 了。还是不行

错了
unpackWARs="true" autoDeploy="true" tomcat 已经设置成这样了@wendal

@wendal 看到解压的是一个 空文件，，里面没有东西 是什么问题？
