Spring Boot Learning Advanced Notes (i)-initial experience, creating basic Web Features

What is Spring boot? , what are the benefits of using spring boot? These things not too much statement, self-Baidu, in this as just a developer's point of view, record their own learning spring boot process, as a learning note to share with you, if there is anything not rigorous or wrong place, please leave a message to point out. First, initialize the structure of the project

Create a basic MAVEN structure project framework through the official website (http://start.spring.io/), such as! Click the button "Generation Project" to generate a basic directory, and then import to eclipse, you can write code! In the process of importing the project, select Maven-Existing maven Projects.

The overall project structure is as follows:

Ii. Introduction of Web Modules

1. In the MAVEN siege configuration file "Pom.xml", add

<dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-web</artifactId> </dependency>

There are two modules in the Pom.xml file by default:

Spring-boot-starter: core modules, including automatic configuration support, logging and YAML;

Spring-boot-starter-test: Test modules, including JUnit, Hamcrest, Mockito

2, write controller, in the package "controller" directory to create "Helloworldcontroller.java" class, through the class annotations, control the specific format of the returned data:

Package Com.zh.SpringBootDemo.controller;

Import Org.springframework.stereotype.Controller;

Import Org.springframework.ui.ModelMap;

Import org.springframework.web.bind.annotation.RequestMapping;

Import Org.springframework.web.bind.annotation.RestController;

@RestController //returns JSON data

@Controller //Jump to the corresponding page

Public class Helloworldcontroller {

@RequestMapping("/hello")

Public String Index () {

return "Hello World";

}

@RequestMapping ("/")

Public String Index (Modelmap map) {

//Add an attribute to read in the template

Map.addattribute ("host", "http://blog.didispace.com");

//Return template file name, corresponding to src/main/resources/templates/index.html

return "index";  

//    }

}

Third, run view

After running "Springbootdemoapplication.java" under the project root, open "http./Localhost:8080/hello" To see the returned results!
