springMVC+thymeleaf form表单提交前后台数据传递
- 后端:
@RequestMapping(value = "/add", method=RequestMethod.POST)
public String save(@ModelAttribute(value="message") Message message) { ... }
- 前端:
<form action="#" th:action="@{/add}" th:object="${message}" method="post"> <input type="text" th:field="*{info}" /> <input type="submit" /> </form>
- Message实体类
1 public class Message { 2 private String info; 3 public String getInfo() { 4 return info; 5 } 6 public void setInfo(String info) { 7 this.info= info; 8 } 9 }
特别注意 th:field
这个属性在Spring-mvc里很重要,承担着绑定后台Bean属性的重任
th:field必须是选择表达式(*{…})
