1. Use of frame function

1.1 write controller class

1.1.1 the controller code to be completed is as follows:

package test.demo.controller;

import com.wuyiccc.helloframework.core.annotation.Controller;
import com.wuyiccc.helloframework.injection.annotation.Autowired;
import com.wuyiccc.helloframework.mvc.annotation.RequestMapping;
import com.wuyiccc.helloframework.mvc.annotation.RequestParam;
import com.wuyiccc.helloframework.mvc.annotation.ResponseBody;
import com.wuyiccc.helloframework.mvc.type.ModelAndView;
import com.wuyiccc.helloframework.mvc.type.RequestMethod;
import test.demo.pojo.Book;
import test.demo.service.BookService;

import java.util.List;

/**
 * @author wuyiccc
 * @date 2020/7/15 22:16
 *Do you say that you have no clothes, and you are in the same robe with your son~
 */
@Controller
@RequestMapping(value = "/book")
public class BookController {


    @Autowired
    private BookService bookService;

    @RequestMapping(value = "/all", method = RequestMethod.GET)
    @ResponseBody
    public List<Book> getAllBooksInfo() {
       return bookService.getAllBooksInfo();
    }


    @RequestMapping(value = "/add", method = RequestMethod.POST)
    public ModelAndView addBook(
            @RequestParam(value = "bookName") String bookName,
            @RequestParam(value = "author") String author
    ){

        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setView("addSuccess.jsp").addViewData("bookName", bookName).addViewData("author", author);

        return modelAndView;
    }


}

1.2 writing service class

1.2.1 code for service:

package test.demo.service;

import com.wuyiccc.helloframework.core.annotation.Service;
import test.demo.pojo.Book;

import java.util.ArrayList;
import java.util.List;

/**
 * @author wuyiccc
 * @date 2020/7/15 22:18
 *Do you say that you have no clothes, and you are in the same robe with your son~
 */

@Service
public class BookService {


    public List<Book> getAllBooksInfo() {

        List<Book> booksInfo = new ArrayList<>();
        booksInfo.add(new Book("book1", "wuyiccc1"));
        booksInfo.add(new Book("book2", "wuyiccc2"));

        return booksInfo;
    }

}

1.3 write POJO class

1.4 specify the property configuration of the framework in the configuration file

1. We indicate in the framework that the configuration file to be scanned is config / hellofframework- config.properties Therefore, the relevant configuration of our framework needs to be written in this configuration file. When the framework starts, it will automatically read the relevant attribute values from this configuration file

1.5 static resources

1. Static resources must be placed in the static / directory. We have instructions in the framework source code

1.6 write JSP page

1. Similarly, the JSP page must also be in the templates / directory, which we have explained in the framework source code

1.7 framework function test

1.7.1 configure Tomcat first and then run it

1.7.2 accessing static resources

1.7.3 visit JSP page

1.7.4 test controller returns JSON data

1.7.5 test data forwarding of controller

2. Future plan

1. thisWrite a framework with ioc-aop-mvc function from scratchThe column is my study notes, of course, the code is not my original, but in the process of sorting out the notes, because I write the explanation according to the code again, so in the process of explanation, I inevitably mixed my personal understanding, and made some improvements on the basis of the original code.
2. In the near future, according to my understanding of spring source code, I will optimize the hellofframework again. This optimization may be to enhance the existing ioc-aop-mvc function, or to add some functions similar to spring
3. Finally, I plan to write a simple usage document for Hello framework after this note is completed. The content of the document may be put on GitHub. It depends on the situation.
4. come on.
