    Constructs a InvocationTargetException with a target exception

    这个异常是指反射异常

    一走到这个地方就报错,显示是有可能会报空指针,但是参数都是有的

     

     

    查询之后,发现是dao也就是我的这个mapper注入的时候,忘记加@autowired了,导致spring容器中没有对这个dao类进行实例化,这个dao类就可能是null,就出现了空指针的情况。

    Constructs a InvocationTargetException with a target exception
    flex通过blazeds与后台java交互,访问flexSession里的值时,总是报上面那个错误。
    让人抓狂,在网上搜,有朋友说在数据库交互时遇到过,这与我的问题相差太远。
    在万般无奈时,发现写入session值时与取值时,两个类名虽相同,实际上是两个不同
    的类,哎,当细心,再细心,再细心哪

    调试程序,遇到:Constructs a InvocationTargetEXception with a target exception

     

    在 java.lang.reflect包中的InvocationTargetException.java类中的InvocationTargetException;

     

    解释说是系统在创建一个类,在构造函数中就出错;

     

    发现:除了构造函数,创建类的实例出错都会报这个错误;

    如有一个成员变量:在定义的时候直接new出来,结果有Exception,也报这个错误
