Java's if-else is a two-way conditional branching statement. It can be used to route program execution through two different paths. The if statement can be used as an if-else-if ladder and can be nested one if statement inside another.
如果异常没有被正确处理,就会导致“Bean初始化错误:Instantiation of bean failed; nested exception is java.lang.ExceptionInInitializerError”问题。为了解决这个问题,你可以在静态初始化块中添加适当的异常处理逻辑,或者将数据库连接操作移到非静态代码块中执行。总结:通过以上步骤和示例代码的分析,你应该能够定位并解...
