    出现错误场景:

    a4c26d1e5885305701be709a3d33442f.png

    在另外的电脑上测试过是可以正常运行的,但是,换到自己电脑上就出现此类错误,主要原因是Tomcat、mysql-connector-java、jdk几个之间的版本不匹配。

    个人推测比较有可能是mysql-connector-java和tomacat版本不匹配,但是不能肯定。(更确切的原因目前也还是不知道)

    我最初的配置是:

    JDK:1.7.0.67

    jre1.7

    tomcat 8.0.21

    mysql-connector-java 5.0.4

    解决方法如下:

    一、更改了tomcat的版本为apache-tomcat-7.0.64

    二、更改mysql-connector-java版本为5.1.24

    二者选其一即可。

    ps:写入数据库的时候用到了数据连接池,如果不使用数据连接池的话不会有这个问题。

  • web jsp 500错误

    今天在写jsp时出现了两个错误,差点让我崩溃!
    第一个错误:
    在写web用户登录实验时,在验证过程中出了问题 ,  “500错误” 说是空引用异常,通过在代码中用System.out.print打印输出,看是哪里出错。发现原来是密码的值没有传进去,后来经过仔细对比发现是在login.jsp中密码的对象名与user.java中的密码对象名不一致  所以传不进去。
    以后单词一定要拼对,前后要一致。

    第二个错误:
    jsp文件在当前工程中可以运行成功,当把这相关的jsp文件和.java文件复制到另一个工程里去就运行不出来。

    出现如下错误:

    The value for the useBean class attribute [model.Data] is invalid
    当时在网上找了很多解决方法都失败了,当我重启Eclipse发现好了!真是神奇。
    所以以后遇到这种问题, 还有一种解决办法就是关掉Eclipse再重启
