这篇文件主要介绍通过springboot 去创建和提交一个表单。
创建工程
涉及了 web，加上spring-boot-starter-web和spring-boot-starter-thymeleaf的起步依赖。
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | <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> |
创建实体
代码清单如下：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | 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; } } |
创建Controller
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | @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" ; } } |
页面展示层
src/main/resources/templates/greeting.html
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | <!DOCTYPE HTML> <html xmlns:th= "http://www.thymeleaf.org" > <head> <title>Getting Started: Handling Form Submission</title> <meta http-equiv= "Content-Type" content= "text/html; charset=UTF-8" /> </head> <body> <h1>Form</h1> <form action= "#" th:action= "@{/greeting}" th:object= "${greeting}" method= "post" > <p>Id: <input type= "text" th:field= "*{id}" /></p> <p>Message: <input type= "text" th:field= "*{content}" /></p> <p><input type= "submit" value= "Submit" /> <input type= "reset" value= "Reset" /></p> </form> </body> </html> |
架构代码如下 :
