Recently the company's project is ready to use MAVEN, switching down is very simple, but the compilation found a very strange phenomenon, is not configured in the Pom jar package or the version of the jar is not configured to appear in the Lib folder, at first thought it was exclusions not set, But after repeated experiments found that can not completely solve the problem, some belong to the project team customized jar package also has multiple versions, and some computers are compiled without p

, because many resources are "long-connected" ways.such as database connection pool This is a typical long-term connection, in order to ensure the efficiency of the connection pool, we can not set the validity of a single connection too short. This has led to the inability of such long connections to respond quickly to changes in the mapping of DNS servers.There is only one workaround: After the mapping of the DNS server changes, the application needs to be restarted to allow long connections to

Can not underestimate this simple finally, seemingly simple problems behind, but hidden countless mystery. Next I will take you step-by-step to uncover this finally mysterious veil.Problem Analysisfirst of all, let me ask you a question: Finally statement blocks are bound to execute?Many people think that finally statement blocks are definitely going to execute, including some very experienced

variable is only visible in the method, construction method, or block of statements that declares it; local variables are static variables on the stack that are seldom used except when declared as constants; Static variables are stored in a static storage area. Static variables are created at the beginning of the program and are destroyed at the end of the program. 3,a instanceof Car. ()=. ()= .

The if...else of the Java conditional statementThe operation of the If...else statement is one step more than an if statement: when the condition is true, the code block of the if part is executed, and if the condition is not true, the else part is entered. For example, if the test result is more than 90 points, reward an IPHONE 5S, or do 500 push-ups.Syntax:650)

I am debugging this statement, how can I skip the jar package and execute it? Sometimes, jump to a breakpoint that I have not set for no reason The third obstacle: write a program, and the errors may not be unde

In programming, there are three basic techniques that can change the process control of a program: Call method; Select Cycle. Here, we mainly talk about the choice statement.The selection statements in Java are essentially the same as in C, including: If statement; If/else statement; Swi
