这段代码是ci中的源码,在/system/database/DB_driver.php文件里,我们可以看到ci框架中在遇到db错误时会报错,然后立马退出。如果你一定要在ci中用try catch ,那么你只能改源码了,当你水平还不到家的时候,千万不要乱改,否则后果自负。 记住ci框架中不能使用try catch!!!
try catch finally简析 **第一种情况:**try中无异常,没有finally。 不会执行catch中的语句,执行完try中语句即返回。 **第二种情况:**try中有异常,没有finally int i=1/0中0不能做除数,有异常,跳转到catch中执行处理异常的语句。 **第三种情况:**try中无异常,有finally,且finally中有return 发现返回的...
异常表记录的是try 起点和终点,catch方法体所在的位置,以及声明捕获的异常种类。通过这些信息,当程序出现异常时,java虚拟机就会查找方法对应的异常表,如果发现有声明的异常与抛出的异常类型匹配就会跳转到catch处执行相应的逻辑,如果没有匹配成功,就会回到上层调用方法中继续查找,如此反复,一直到异常被处理为止,或者停止进...

可以看到我们指明的异常监控的是try-catch中的指令,而编译器生成的则是监控异常处理中的指令。 继续看字节码指令,如下图: 根据异常表我已经圈出了第一个异常处理的指令,从52行开始,astore_2表示将索引存储到本地变量表中第2项,实际上就是将“FileNotFoundException e”产生的变量e存入,53至56行指令则是将数字...

Use the try block to contain statements that might raise or throw an exception. Place statements to handle exceptions in one or more catch blocks.
