示例【Spring MVC 使用AnnotationFormatterFactory格式化数据】

创建index.jsp

<body>
	<h4>测试表单数据格式化</h4>
	<form action="register" method="post">
		<table>
			<tr>
				<td>日期类型:</td>
				<td><input type="text" name="birthday"></td>
			</tr>
			<tr>
				<td>整数类型：</td>
				<td><input type="text" name="total"></td>
			</tr>
			<tr>
				<td>百分数类型：</td>
				<td><input type="text" name="discount"></td>
			</tr>
			<tr>
				<td>货币类型：</td>
				<td><input type="text" name="money"></td>
			</tr>
			<tr>
				<td></td>
				<td><input type="submit" value="提交"></td>
			</tr>
		</table>
	</form>
</body>

创建User

package com.po;
import java.util.Date;
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.format.annotation.NumberFormat;
import org.springframework.format.annotation.NumberFormat.Style;
public class User {
	//日期类型
	@DateTimeFormat(pattern="yyyy-MM-dd")
	private Date birthday;
	//正常数字类型
	@NumberFormat(style=Style.NUMBER,pattern="#,###")
	private int total;
	//百分数类型
	@NumberFormat(style=Style.PERCENT)
	private double discount;
	//货币类型
	@NumberFormat(style=Style.CURRENCY)
	private double money;
	public Date getBirthday() {
		return birthday;
	}
	public void setBirthday(Date birthday) {
		this.birthday = birthday;
	}
	public int getTotal() {
		return total;
	}
	public void setTotal(int total) {
		this.total = total;
	}
	public double getDiscount() {
		return discount;
	}
	public void setDiscount(double discount) {
		this.discount = discount;
	}
	public double getMoney() {
		return money;
	}
	public void setMoney(double money) {
		this.money = money;
	}
	@Override
	public String toString() {
		return "User [birthday=" + birthday + ", total=" + total + ", discount=" + discount + ", money=" + money + "]";
	}
}

创建UserController

package com.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import com.po.User;
@Controller
public class UserController {
	@RequestMapping("/register")
	public String register(@ModelAttribute User user,Model model) {
		System.out.println(user);
		model.addAttribute("user", user);
		return "success";
	}
}

配置springmvc-config.xml

<!-- 装配自定义格式化转换器-->
<mvc:annotation-driven/>
<!-- 定义扫描的包 -->
<context:component-scan base-package="com.*" />
<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value=""></property>
	<property name="suffix" value=".jsp" />
</bean>

创建success.jsp

<body>
	<form:form modelAttribute="user" action="">
	<table>
		<tr>
			<td>日期类型：</td>
			<td><form:input path="birthday"/></td>
		</tr>
		<tr>
			<td>整数类型：</td>
			<td><form:input path="total"/></td>
		</tr>
		<tr>
			<td>百分数类型：</td>
			<td><form:input path="discount"/></td>
		</tr>
		<tr>
			<td>货币类型：</td>
			<td><form:input path="money"/></td>
		</tr>
	</table>
	</form:form>
</body>
