電子商務社交平臺源碼請加企鵝求求：叄五叄六貳四柒貳五九。這篇文件主要介紹經過springboot 去建立和提交一個表單。html

建立工程

涉及了 web，加上spring-boot-starter-web和spring-boot-starter-thymeleaf的起步依賴。web

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
 
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
 
 
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-thymeleaf</artifactId>
            </dependency>
 
    </dependencies>複製代碼

建立實體

代碼清單以下：spring

public class Greeting {
 
    private long id;
    private String content;
 
    public long getId() {
        return id;
    }
 
    public void setId(long id) {
        this.id = id;
    }
 
    public String getContent() {
        return content;
    }
 
    public void setContent(String content) {
        this.content = content;
    }
 
}複製代碼

建立Controller

@Controller
public class GreetingController {
 
    @GetMapping("/greeting")
    public String greetingForm(Model model) {
        model.addAttribute("greeting", new Greeting());
        return "greeting";
    }
 
    @PostMapping("/greeting")
    public String greetingSubmit(@ModelAttribute Greeting greeting) {
        return "result";
    }
 
}複製代碼

        <p>Message: <input type="text" th:field="*{content}" /></p>
        <p><input type="submit" value="Submit" /> <input type="reset" value="Reset" /></p>
    </form>
