Advantages of springbok
The advantages of springbok are mainly reflected in the following aspects:
1. Rapid development: SpringBoot provides many out-of-the-box functional modules, which enables us to quickly build a runnable JavaWeb application.
2. Simplify configuration: SpringBoot simplifies the configuration process by automatically configuring many components.
3. Easy to deploy: SpringBoot provides many packaging methods, which makes it easy for us to deploy applications in different environments.
How to use jumping boots
Developing JavaWeb applications with SpringBoot is mainly divided into the following steps:
1. Create a project: You can use SpringBoot to create a project through the official SpringInitializr, or you can use SpringBoot by creating Maven or Gradle projects in the IDE.
2. Add Dependencies: We need to add some dependencies in the created project, which will provide some functional modules out of the box.
3. Writing code: After adding the dependencies, we can start writing code. SpringBoot provides many comments and tool classes, which makes it easier for us to write code.
4. Run the application: After writing the code, we can use the plug-in provided by SpringBoot to package the application, and we can use the command line or IDE to start the application.
example
Let's use a simple example to demonstrate how to use SpringBoot to develop JavaWeb applications.
1. Create a project
First, we need to create a SpringBoot project. We can create a project in the official SpringInitializr, or create a Maven or Gradle project in the IDE, and add the dependency of SpringBoot.
2. Add dependencies
In the created project, we need to add some dependencies. In this example, we need to add the dependency between SpringWeb and Thyme Leaf. We can add the following dependencies in pom.xml:
` ` xml
springframework.boot
Spring boot starter net
springframework.boot
Thyme leaf
```
Write code
After adding the dependencies, we can start writing code. In this example, we need to write a simple controller and a thyme template. We can create a controller named DemoController in the src/main/java/com/example/demo directory, and the code is as follows:
` ` java
@ controller
publicclassDemoController{
@GetMapping("/")
publicStringindex(Modelmodel){
model.addAttribute("message "，" HelloWorld！" );
Return to Index;
}
}
```
In this controller, we use the @GetMapping annotation to specify the access path, use the model to transmit data, and use Thyme's template engine to present the page.
Create a thyme template named index.html in the src/main/resources/templates directory. The code is as follows:
` ` html
SpringBootDemo
```
In this template, we use the syntax of Thyme to present the page, and use $ ＄{ message} to display the data passed from the controller.
Run the application
After writing the code, we can use the plug-in provided by SpringBoot to package the application, and we can use the command line or IDE to start the application. In this example, we can use Maven to package the application and use the command line to start the application. We can execute the following command to package the application:
```
Mvn packet
```
After executing this command, an executable file named demo-0.0. 1-SNAPSHOT.jar will be generated in the target directory. We can use the following command to start the application:
```
Java-jartarget/demo-0 . 0 . 1-snapshot . jar
```
After starting the application, we can visit http://localhost:8080/ in the browser and see the page we wrote.
