如何捕获JVM_Bind异常：java.net.BindException：地址已在使用中

Question

How can i catch the Bind exception? i used the following lines

try{
    //some code
}
catch (java.net.BindException e) {
    //some code
}

and

try{
    //some code
}catch (BindException e) {
    //some code
}

but none of them is working giving me the error

`java.net.BindException: Address already in use: JVM_Bind
java.net.DualStackPlainSocketImpl.bind0(Native Method)
java.net.DualStackPlainSocketImpl.socketBind(DualStackPlainSocketImpl.java:106)
java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:376)
java.net.PlainSocketImpl.bind(PlainSocketImpl.java:190)
java.net.ServerSocket.bind(ServerSocket.java:376)
java.net.ServerSocket.<init>(ServerSocket.java:237)
...

Can anybody give me an idea? Thanks in advance :)

Answer 1

Are you sure that the try block surrounds the code that throws the exception? I say, either it's not, or that the BindException is wrapped with some other Throwable before thrown. In that case, try

try {
    // the problematic code
} catch (Throwable t) { // <--- here, Throwable
   // better log the error here
}
