SpringMVC表单的验证及国际化
1.导入Hibernate-validate需要的jar包
2.编写实体类User并加上验证注解
public class User { public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Date getBirth() { return birth; } public void setBirth(Date birth) { this.birth = birth; } @Override public String toString() { return "User [id=" + id + ", name=" + name + ", birth=" + birth + "]"; } private int id; @NotEmpty private String name; @Past @DateTimeFormat(pattern="yyyy-MM-dd") private Date birth; }
ps:@Past表示时间必须是一个过去值
3.在jsp中使用SpringMVC的form表单
<form:form action="form/add" method="post" modelAttribute="user"> id:<form:input path="id"/><form:errors path="id"/><br> name:<form:input path="name"/><form:errors path="name"/><br> birth:<form:input path="birth"/><form:errors path="birth"/> <input type="submit" value="submit"> </form:form>
ps:path对应name
4.Controller中代码
@Controller @RequestMapping("/form") public class formController { @RequestMapping(value="/add",method=RequestMethod.POST) public String add(@Valid User u,BindingResult br){ if(br.getErrorCount()>0){ return "addUser"; } return "showUser"; } @RequestMapping(value="/add",method=RequestMethod.GET) public String add(Map<String,Object> map){ map.put("user",new User()); return "addUser"; } }
ps:
1.因为jsp中使用了modelAttribute属性,所以必须在request域中有一个"user".
2.@Valid 表示按照在实体上标记的注解验证参数
3.返回到原页面错误信息回回显,表单也会回显
5.错误信息自定义
在src目录下添加locale.properties
NotEmpty.user.name=name can't not be empty Past.user.birth=birth should be a past value DateTimeFormat.user.birth=the format of input is wrong typeMismatch.user.birth=the format of input is wrong typeMismatch.user.id=the format of input is wrong在SpringMVC配置文件中配置
<!-- configure the locale resource --> <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> <property name="basename" value="locale"></property> </bean>
6.国际化显示
在src下添加locale_zh_CN.properties
username=账号 password=密码locale.properties中添加
username=user name password=password创建一个locale.jsp
<body> <fmt:message key="username"></fmt:message> <fmt:message key="password"></fmt:message> </body>
在SpringMVC中配置
<!-- make the jsp page can be visited --> <mvc:view-controller path="/locale" view-name="locale"/>
让locale.jsp在WEB-INF下也能直接访问
最后,访问locale.jsp,切换浏览器语言,能看到账号和密码的语言也切换了
