Spring 3.0 supports configuration based on class annotations. The main function is from a sub-project named javaconfig of spring. Currently, javaconfig has been upgraded to a part of spring's core framework. A pojo labeled with @ configuration annotation can provide bean configuration information required by spring and XML-based configuration. Its a

the product of two numbers and return the result: function myFunction(a,b){return a*b;}document.getElementById("demo").innerHTML=myFunction(4,3); The innerHTML of the "demo" element will be: 12 You can also use the return statement when you only want to exit the function. The return value is optional: function myFunction(a,b){if (a>b) { return; }x=a+b} If a is greater than B, the above code exits from the function and does not calculate the sum of a and B.
