SPRING MVC3.2 Case Study--spring MVC3 's various URL mappings +jsp view jumps (3) __jsp

This section focuses on using SPRINGMVC for controller to view, involving code that contains JSP views,

Unlike the largest configuration point in the previous chapter:

The controller @ResponseBody that no view points to is critical code that returns content directly without turning to the JSP view

@Controller public
class Mappingcontroller {

	@RequestMapping ("/mapping/path") is public
	@ResponseBody String Bypath () {return
		' mapped by path! ';
	}
}

Controller pointing to a specific view, no @responsebody, indicating that a JSP view is pointing

@Controller
@RequestMapping ("/views/*") public
class Viewscontroller {

	@RequestMapping (value= "HTML") method=requestmethod.get) Public
	String prepare (model model) {
		model.addattribute ("foo", "Bar");
		Model.addattribute ("Fruit", "apple");
		return "views/html";
	}

Four usage based on view steering:

1. Make a steering view of yourself

	  http://127.0.0.1:8010/views/html---> Corresponding views/html.jsp
	@RequestMapping (value= "HTML", method= requestmethod.get) Public
	String prepare (model model) {
		model.addattribute ("foo", "Bar");
		Model.addattribute ("Fruit", "apple");
		return "views/html";
	}
	

2.spring point to the default view, Org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator the default view to the turn, see log information:

DEBUG Dispatcherservlet Unable to locate requesttoviewnametranslator with Name ' Viewnametranslator ': Using default [Org.s PRINGFRAMEWORK.WEB.SERVLET.VIEW.DEFAULTREQUESTTOVIEWNAMETRANSLATOR@55A58F]

  http://127.0.0.1:8010/views/viewName---> Corresponding views/viewname.jsp
	@RequestMapping (value= "/viewname", method=requestmethod.get) public
	void Usingrequesttoviewnametranslator (model model) {
		Model.addattribute ("foo", "Bar");
		Model.addattribute ("Fruit", "apple");
	}
	

3.URI @PathVariable Acquisition, note that the parameter names must be consistent. Such as:

  http://127.0.0.1:8010/views/pathVariables/bar/apple---> Corresponding views/html.jsp
	@RequestMapping (value=) Pathvariables/{foo}/{fruit} ", Method=requestmethod.get) public
	string Pathvars (@PathVariable string foo, @ Pathvariable String Fruit) {
		//No need to add @PathVariables ' foo ' and ' fruit ' to the model
		//They would be merge D in the model before rendering return
		"views/html";
	}

4. Assign values to JavaBean using the @pathvariable of the URL

Http://127.0.0.1:8010/views/dataBinding/bar/apple---> Corresponding views/databinding.jsp
	@RequestMapping (value=) Databinding/{foo}/{fruit} ", method=requestmethod.get) public
	String dataBinding (@Valid JavaBean JavaBean, Model Model) {
		//JavaBean "foo" and "fruit" properties populated from URI variables return 
		"views/databinding";
	}

public class JavaBean {
	
	@NotNull
	private String foo;

	@NotNull
	private String fruit;
Note that there is a get SET method, space is limited, not in the article
