SpringBoot教程第20篇:表单提交
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。
<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";
}
}
