idea+weblogic出现的问题

本地使用weblogic 配置Idea 登录出现的问题

1、登录失败

错误信息：登录时校验用户信息发生异常！
错误原因：生成的验证码，在放入request.getSession.setAttribute后；登录时校验，未获取attribute的值；

代码位置：
前台：

request.getSession().setAttribute(Const.SESSION_VERIFYCODE, buffer.toString());

在weblogic改为https登录时，下面这一行会报错

String verifyCodeSession = (String) request.getSession().getAttribute(Const.SESSION_VERIFYCODE);

取得值为null

原因：访问路径的问题，不要写localhost，要写具体的ip，比如https://10.12.12.12:7002/webDemo

2、进入首页出错

后台日志：

原因：有可能是Jdk版本不对，本地使用的1.8，后来在weblogic服务创建域的时候使用1.7，可以访问。

3、线程泄露，内存溢出

Exception in thread “[STANDBY] ExecuteThread: ‘1’ for queue: ‘weblogic.kernel.Default (self-tuning)’”

原因：JVM内存使用过大，应扩大内存。

参考：
https://blog.csdn.net/su1573/article/details/102706086

D:\Oracle\Middleware\user_projects\domains\base_domain\startWebLogic.cmd

在call 上一行增加：

set USER_MEM_ARGS=-Xms512m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=1024m

或者进入：

D:\Oracle\Middleware\user_projects\domains\base_domain\bin\setDomainEnv.cmd

在218行增加：

set USER_MEM_ARGS=-Xms512m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=1024m

待续...
