II. Answer the Question
1. What is Apache Maven and Gradle?
 Apache Maven is a software project management and comprehension tool. Based on
the concept of a project object model (POM), Maven can manage a project's build,
reporting and documentation from a central piece of information.
 Gradle is an open-source build automation system that builds upon the concepts of
Apache Ant and Apache Maven and introduces a Groovy-based domain-specific
language (DSL) instead of the XML form used by Apache Maven for declaring the
project configuration.
2. What is Web.XML(Web deployment descriptor) use for in spring framework?
 web.xml is a deployment descriptor file while using J2EE. ... Servlet to be accessible
from a browser, then must tell the servlet container what servlets to deploy, and what
URL's to map the servlets to. This is done in the web.xml file of your
Java web application
3. What is <annotation-driven/> tag use for in spring configuration?
 <annotation-driven> is used to detect the annotation like @Controller,
@ResponseBody,….
4. List of 3 type of ViewResolver in spring framework and their usage?
 AbstractCachingViewResolver : Abstract view resolver that caches views. Often views
need preparation before they can be used; extending this view resolver provides
caching.
 XmlViewResolver : Implementation of ViewResolver that accepts a configuration file
written in XML with the same DTD as Spring’s XML bean factories. The default
configuration file is /WEB-INF/views.xml.
 ResourceBundleViewResolver : Implementation of ViewResolver that uses bean
definitions in a ResourceBundle, specified by the bundle base name. Typically you
define the bundle in a properties file, located in the classpath. The default file name
is views.properties.
 UrlBasedViewResolver : Simple implementation of the ViewResolver interface that
effects the direct resolution of logical view names to URLs, without an explicit
mapping definition. This is appropriate if your logical names match the names of your
view resources in a straightforward manner, without the need for arbitrary mappings.
 InternalResourceViewResolver : Convenient subclass of UrlBasedViewResolver that
supports InternalResourceView (in effect, Servlets and JSPs) and subclasses such as
JstlView and TilesView. You can specify the view class for all views generated by this
resolver by using setViewClass(..).
 VelocityViewResolver/FreeMarkerViewResolver : Convenient subclass of
UrlBasedViewResolver that supports VelocityView (in effect, Velocity templates) or
FreeMarkerView ,respectively, and custom subclasses of them.
 ContentNegotiatingViewResolver : Implementation of the ViewResolver interface
that resolves a view based on the request file name or Accept header.

5. Describe annotation bellow with example:
-@Controller
@Controller is similar annotation which mark a class as request handler.
package com.howtodoinjava.web;
@Controller
public class HomeController
{
@GetMapping("/")
public String homeInit(Model model) {
return "home";
}
}
-@Service
@Service is a stereotype for the service layer.
Package com.in28minutes.login
inport org.springframwork.beans.factory.annotation.autowired;
@Controller
public class loginController{
@Autowired
LoginService Service;
@RequestMapping(value="/login",method=RequestMethod.GET)
public String showLoginPage(){
return "login";
}
}
-@Repository
@Repository is a stereotype for persistence layer.
package com.spring.anno;
@Service
public class TestBean
{
public void m1()
{
//business code
}
}
package com.spring.anno;
@Repository
public class TestBean
{
public void update()
{
//persistence code
}

}
-@Rest Controller
@Rest Controller which is a convenience annotation that does nothing more than add the
@Controller and @ResponseBody annotations.
@Target(value=TYPE)
@Retention(value=RUNTIME)
@Documented
@Controller
@ResponseBody
public @interface RestController
-@Request Mapping
@RequestMapping is one of the most common annotation used in Spring Web applications.
This annotation maps HTTP requests to handler methods of MVC and REST controllers.
@RequestMapping(value = "/ex/foos", method = RequestMethod.GET)
@ResponseBody
public String getFoosBySimplePath() {
return "Get some Foos";
}
-@Path Variable
@PathVariableannotation used to get variable name and its value at controller end. e.g.
@RequestMapping(value = "/ex/foos/{fooid}/bar/{barid}", method = GET)
@ResponseBody
public String getFoosBySimplePathWithPathVariables
(@PathVariable long fooid, @PathVariable long barid) {
return "Get a specific Bar with id=" + barid +
" from a Foo with id=" + fooid;
}
-@RequestParam
The @RequestParam annotation is used with @RequestMapping to bind a web request
parameter to the parameter of the handler method.
The @RequestParam annotation can be used with or without a value. The value specifies
the request param that needs to be mapped to the handler method parameter, as shown
in this code snippet.
The default value of the @RequestParam is used to provide a default value when the
request param is not provided or is empty.
@RestController
@RequestMapping("/home")
public class IndexController {
@RequestMapping(value = "/fetch", params = {"personId=10"})

6. 6ចងក្រងដោយ: ថនសារិ
String getParams(@RequestParam("personId") String id){
return "Fetched parameter using params attribute = "+id;
}
@RequestMapping(value = "/fetch", params = {"personId=20"})
String getParamsDifferent(@RequestParam("personId") String id){
return "Fetched parameter using params attribute = "+id;
}
}
-@Model Attribute
@ModelAttribute is an annotation that binds a method parameter or method return
value to a named model attribute and then exposes it to a web view.
@ModelAttribute("person")
public Person getPerson(){
return new Person();
}
-@Request Header
@RequestHeader that can be used to map controller parameter to request header value
@Controller
public class HelloController {
@RequestMapping(value = "/hello.htm")
public String hello(@RequestHeader(value="User-Agent") String userAgent)
//..
}
}
-@Request Body
@Request Body is Annotation indicating a method parameter should be bound to the body
of the HTTP request.
@RequestMapping(path = "/something",method = RequestMethod.PUT)
public void handle(@RequestBody String body, Writer writer) throws IOException {
writer.write(body);
}
-@Response Body
The @ResponseBody annotation can be put on a method and indicates that the return
type should be written straight to the HTTP response body (and not placed in a Model, or
interpreted as a view name).
@RequestMapping(path = "/something",method = RequestMethod.PUT)

public @ResponseBody String helloWorld() {
return "Hello World";
}
