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。 Spring Cloud大型企业分布式微服务云架构源码请加一七九一七四三三八零

<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：

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

@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

<!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>
