Writing code is good and multi-purpose multi-purpose trycatch throws well

Which I don't feel better, now that others give us trycatch and throws, that is to say, both of which have the most suitable place, depending on the business to see what you need, usually there is a place dedicated to all exceptions thrown trycatch, directly throws elsewhere, such as spring exceptionhandler is about

CodePudding user response:

Depending on the specific nor demand, in the framework throws, of course, for a business to try, and then feedback to the front

The ITEM 73 Effective Java
Top method should capture the low-level exceptions thrown, and will capture abnormal translated into can comply with the intention of abnormal layer method, throw again, that is often said the unusual escape,

Think need exception thrown to the outside of the throw, don't need to catch out

CodePudding user response:

Try catch used to handle exceptions, throws to outer throws an exception,
For backend project controller calls the service call dao layer, layer is generally an exception is thrown outwards, the outermost controller to try and catch catch, and for processing, then return to the front, report user errors after processing

CodePudding user response:

Try catch their processing,
Throws exception class is to the JVM
Difference with the JVM process has unusually direct
Terminates
Try catch the abnormal will not end even if run
Will still perform the following code,

CodePudding user response:

Processed by the small white feel yourself Chou has actually had better have a try catch, for other people to do service throws
